The very best stereo phones.

Overall

I purchased porta pro Jr. Headphones in 1989. I fell in love with them. The bass,midrange and treble are perfect.This stereo phones produce a clear,clean sound.The bass is not too boomy and muddy.I am currently unemployed.I will talk to a close friend of mine to see if he can order this stereo phones for me.

Best Pair of Headphones I Own

Overall

I was introduced to Koss by a friend in 2011 with one of their now discontinued in-ear headphones and thought they were excellent all the way around. When I went to college in 2013 I needed a portable, lightweight pair of headphones that would last me all the way through. I researched them a bit and I ended up buying a pair of Koss PortaPros. I recently had to buy replacement ear pads since the original ones were worn ragged. Now its 5 years later and the only regret I have is spending the extra money to get the headphone attachment.
My only complaint is that even though the headphone pressure is quite slight, it can get tiring after 8+ hours of continuous use.
Thank you for a superior product that far exceeds expectations Koss!

excellent headphones

Overall

I have more expensive headphones, but I enjoy listening to music longer with these headphones. I have had mine for over 5 years now. When and if they break, I intend to buy another pair.
Review by Dan / (Posted on 7/16/2018)

My new favorites.. can't stop listening.

Overall

These headphones are quite neutral, slightly forgiving of poor recordings and are comfortable with the different firmness options. I now know what the hype is about with these headphones. I have not been wanting to listen to my music so often in years.
Review by ekolite / (Posted on 7/16/2018)

Outstanding

Overall

Just returned an older pair for exchange and I will have to say you can't beat Koss and their lifetime warranty. Received the new pair today. Easy no hassle return. I have 2 pair if porta pros and I think these are the best for the money. You can't go wrong buying these

Excellent lightweight headphones

Overall

I love the koss porta pro, they are lightweight and the sound is excellent with powerful bass. I really wish they make a bluetooth version. Please don't change anything just replace the cord with bluetooth :-)

Great headphone though a bit fragile

Overall

I have had many many pairs of these, the sound quality and comfort is exactly what I expect in a headphone and they are my main pair. The only issue I have is that the collapsible part never seems to work out for me and the wires tend to break a lot.

You have to not be rough with them and put them somewhere where they can not potentially be broken. Other than the durability these are the best pair of headphones I have ever bought.
Review by Storm / (Posted on 1/1/2018)

Great look, great sound, great price

Overall

I went through the many reviews about the Porta Pro On Ear Headphone and for my budget, it looked the real thing to me. My older headphones were just the earbud/earphone type and I was already happy with them. As soon as I got my Porta Pro, I tried it on and I love it. I bought another for my Uncle after a few days. He loved it too.

best head band headphones in theMarket

Overall

I have always been a titanium drivers Koss fan, and just last year I gave this one a chance to come into my headphones collection in spite they are not. Nevertheless they're awesome with punchy Bass sound, and are comparable to some other active and much more expensive brands in fact. These Koss are just your choice for long lasting periods for rock music. Yes they lack the krispy highs of some of the other Titanium featured Koss, but they are well balanced and detailed in delivering cord sounds, and if you rather more Bass punch, this is your choice. I didnt like the short cord lenght thais much. But headset metallic band and comfortability are worth it their cost. excelent performers.

Surprise

Overall

I bought them 1985 mostly for bicycling also for winter. They just do not break up after years of heavy use. I had many years of non use because could not get the replacement cushions in my country. Years went by, almost all of my music is converted to apple lossless and going for a walk with these I have say there rock and sound better with classic too than most of the modern in ear plugs. Much more comfortable than any in ear that I have tried, Koss being near. Very durable.

2 years Pro

Overall

Hi,

I have been using them for two years now and they are exceptional now more than ever.

I compare them to newer models from work colleagues at similar price tags (event sennheisers) and can't find anything better.

I want to congratulate you on your professional product and will recommend them to anyone.

Hearing Your Music for the First Time

Overall

There is a reason these headphones have been around forever; Its simple, they work.
They work so well in fact that when I put them on it was like I was listening to my music for the first time, and no I wasn't listening to Madonna. I have heard things I had never noticed before, everything is so clear and balanced. I have bought numerous headphones in this price range but these are definitely the best.

They BANG Hardcore Rap and Headbanger Metal!!!

Overall

Had these for many years and they sound great! Bass good mids and crystal-clear highs!!! They BANG hardcore rap & metal, and Classical & Jazz sound nice and clean. Best hp (for the price of course) I had in many years. In my opinion they blow BEATS by Dre out the water!!! Sound good on iPod, PC and home receiver.

Very long tima ago..

Overall

I own my first Porta sind 31 years!! Bought anno 1985, it is still working. Although, i've purchased an newer one for 3 years ago, to preserve to older one. Really a good thing to listen music without limitations. And i will never use phones with noise cancelling. Never!

Excellent product

Overall

I've been using these earphones for ages. There are solid. The 60 ohms bandwidth is the key. It makes these earphones the best. You get for what you pay for.
Highly recommended.
Review by ludobubner / (Posted on 10/1/2016)

Just WOW!!!

Overall

So I gotta say that a little research went a long way with these. Just look at the specs and you'll notice the range, the sensitivity is the norm so no special gear other than your smartphone and iDevices needed, and the Lifetime Warranty- really a lifetime warranty if shit happens to them. I am utterly pleased with these headphones for about 5years now. And if you are into the retro look I guess these work. Only con is that these bleed sound so others will hear what you are listening to, so please remember to listen within reason master blaster and to play good music lol. Enjoy!!!

Great sound, very comfortable

Overall

I have had these headphones for about four months. The Porta Pros sound great with all kinds of music. They have an "open," realistic sound which is well-balanced. They are very lightweight and comfortable, as well as extremely portable. The quality of construction seems very good, and they come with a warranty. I don't think I could be happier with these, especially considering the very reasonable price.

Porta Pro Headphones.

Overall

I have owned my pair of Porta Pro for 6 years ,just had to order the new ear pads for them which is normal for 6 years of use ,and the pads are inexpensive. The sound after 6 years is still impeccable,and I am a bass hound and a lover of Trance & Blues ,also Classic Rock. These headphones fulfill excellent sound in all the different music categories. There durable and nothing has broken on them,as for them pulling a hair from time to time no big deal ,I figure by having a small piece of my hair in them proves there mine per my DNA if ever stolen,Laugh! Long story short : I LOVE THEM!!!

INPUT FROM A PRO

Overall

I RECOMMENED THE PORTA PRO'S TO A D/J ONECE, HE STATED THAT HE'S NEVER HEAD ANYTHING LIKE THE HEADPHONES BEFORE, HE WAS IMPRESSED BY THE BASE PRODUCTION AND THE CLEAR SOUND.....
Review by BRYANT / (Posted on 3/11/2016)

Excellent for the price, great bass/EQ, lightweight and durable

Overall

I've been through them all - From some of the most expensive phones to the lesser priced and settled on the PortaPros for just about everything I do. I HATE earbuds and far prefer the response and quality from over-the-ears but they're usually too bulky. Enter the Koss PortaPro - they're the perfect balance of earbud comfort and over-the-ear performance.

They are EQ'ed very well. No overpowering bass or compressed, over-compensation for the audio spectrum like the "B" phones (2 "B" brand names - You'll have to figure them out).

I use the PortaPros primarily as lightweight studio monitor phones as they're so comfortable and are EQ'ed so naturally.

The metal band is durable but as some others comment, it can get stuck in your hair when you remove them but to me this is part of the 'charm' of the PortaPros. Plus my hair is short, so I'm not too concerned.

Great warranty and support from Koss. All in all, the best band-for-buck headphone out there in my opinion.

Perfeito!!!

Overall

Eu possuo um Porta Pro há mais de 10 anos. Lógico que cuido dele muito bem! Mas o equipamento está em perfeito estado de glória! Pra mim, é sem igual. Confortável, excelente som! O melhor!
Review by Daniel Mota / (Posted on 1/28/2016)

Wow customer support

Overall

I had a 15 year old pair of porta pro's that broke. Koss replaced under their lifetime warranty. Brand new pair, same old beautifully balanced sound.

Only suggestion is that Koss offer a version with a microphone.

Great sounding headphones for the price / metal headband needs to be redone

Overall

As everyone says, these headphones don't cease to amaze. I compare them to other brands at 3x, 4x, 10x the price and they are holding their own. They are so good that I can comfortably say they could be used to produce/write music on your laptop while you travel. You will hear all the lows, mids, and highs with these headphones. Their sonic signature is slightly mid-forward and warm in the treble section (rolls off a bit). Bass is solid and extends quite low.

BUT, the metal headband catches my hair from time-to-time and pulls a root out if I am not extremely careful! Ouch! This needs a re-work.

Koss, you have a winner with these headphones. Make a v2 of this which is still portable and compact but with a headband that is hair/scalp friendly please!

If it weren't for this gripe, I would have given it 5 stars.

Overall

just got my new koss porta pro classic and I 'm loving them. I have hooked it up to all my devices and I must say the sound is the great . if your a music lover of Jazz, Beethoven, classic R&B or classic rock, then you can't beat it. I have a few headphones and for the money you can't go wrong. looking into buying more of your product thank you -tooley2

Great for glasses-wearers

Overall

I end up wearing these for about 95% of my day, at home and for work. They're so lightweight that I forget that I have them around my neck. These also play nice with glasses! My glasses and the headphones never rub or clack together.
I've had mine for half a year and listening to other small headphones now, the Porta Pro set has noticeably better sound quality.
I firmly believe that humans will never create a more comfortable pair of headphones than these.
Review by Call Ins / (Posted on 11/27/2015)

You won't believe your ears

Overall

Take what other reviewers have said about these headphones, believe them, and then multiply it by 100.I found them here in review http://topchoice.best/main-review/best-headphones . I received a pair of Koss UR-20s as a gift years ago and loved them so naturally I looked to Koss again when replacing my portable/on-the-go headphones. I figured they were good, especially considering that the design seems unchanged since the 1980s (which has to mean something), but I also figured that this was one of those things that was just too good to be true. However, these are bar-none the most amazing headphones I have ever put on my head. Listening to some of my favorite songs for the first time was one of those 'wow' moments where you realize you have found something that changes your expectations completely. The bar will be raised the instant you hear the bass response and incredible acoustic qualities of these light, comfortable headphones.
I don't know what I'm impressed with the most: the amazing bass, the excellent stereo division, or how loud they can get! These things are just as amazing as most of the reviews show them to be and then a lot more... I was worried about the eighties styling, but in person they don't look bad at all. I hate headphones that scream for attention, but these don't look like that when you have them on and I have already been wearing them in public (something I didn't think I would do after only seeing the picture of them online). And even if they're a bit outdated in appearance, the design is so functional you won't even give looks a second thought after you put them on.
One thing is for sure: these things have plenty of bass! Not too much (not "boomy"), but they seem properly tuned for listening to things without "bass booster" turned on, which I like. Even with the bass settings adjusted high, the bass remains clear and crisp. I'm not sure how much power these can handle without damaging them, but I listen to them very loud and they do not sound distorted or stressed at all.
I can't say enough good things about these PortaPros! They're simply amazing. These are the first headphones (or speakers) I've had that sound absolutely awesome without adjusting the equalizer or pumping up the bass. They sound good on everything from R&B to Country and everything in-between. I've been especially impressed that they pull the bass and highs out of a song without getting that shrill, tinny treble that plagues so many headphones. If there ever was a question about the quality of Koss stereophones in my mind, these PortaPros have put it to rest and made me into a lifetime customer!
Review by alexascott / (Posted on 11/16/2015)

better but not the best

Overall

it's very very good phones in the field of sound but it has poor material of the cable, case, and even plastic of phone. I was expecting to have phones in Apple quality for its price.
Review by starik061 / (Posted on 11/11/2015)

Koss Porta Pro

Overall

I had 4 pairs in about 5 years (only 1 actually broke). It doesn't matter what other headphones I own, I keep coming back for these, each and every time. I have yet to find a pair of headphone at this price range of 50$ and even more, that can give me a sound like these little ones do. I listened headphones that were priced at 200-300$ and they are still not as good as Koss Porta Pro. The more expensive headphones, yeah, they have more clarity on all ranges, but their sound isn't full enough, it doesn't have that oomph (not speaking about bass here) that Koss does. Probably the best thing about them is that, even if they have 60ohm impedance rating, they are very easy to drive. I am listening them with an old iRiver T10 (you won't believe how good this player sounds) without any kind of amp. I own their direct rival also, the Sennheiser PX100 II, but I cannot say which of them I like more. They are quite different in sound signature and they complete each other very well, so if you have the possibility, go and buy both of them as you will not regret it. Bottom line: one of the best headphones I have ever. heard

Pros: sound quality, very comfy, unique retro style

Cons: cable quality
Review by Alex / (Posted on 5/4/2015)

Not Best in Price Range.... Simply the Best!

Overall

I have used $250 headphones that didn't sound as good as my Koss PortaPro headphones. They are crystal clear in the upper and mid ranges and give amazing quality of sound in the bass ranges. Headphones are not supposed to be good if you want to hear full bass. But these are. Forget the latest fadphones and get these. Unless you are wearing headphones just to show off the latest fad brand name. Then go ahead and spend your money on junk. The PortPros are the best, not just for the money, but for 5 times the money, at least.

Pros: the perfect sound in all ranges, especially bass

Cons: wire to each earphone instead of one, with connection to other within the set
Review by JoeG / (Posted on 3/9/2015)

is koss Porta pro worth

Overall

Quite nice but for me just 50 usd can get this ?? It's really worth it but only for the sound and portability

Pros: it contains a 3d sounds and it's cheap and portable

Cons: keep clicking hair and old fashioned design
Review by jobwong2cheng / (Posted on 3/8/2015)

Worth every dime!

Overall

I will always recommend them with all my heart! The sound so great, it beats everything at the same price. After getting them in 2013, i still have them with no visual defect.

Pros: Sound, head resting, Sound again!
Review by Daniel / (Posted on 3/1/2015)

Best sound

Overall

I just did a side-by-side comparison of this with the compomprable Bose headphones (SoundTrue on-ear). The Koss sound is so good it's difficult to review, because it's flawless. The Koss bass was more warm, while the Bose treble sounded chintzy and unreal.

Pros: light, small, prefect sound

Cons: disign looks funny to me

Porta Pro

Overall

I like these because they provide good portable sound without solidly plugging up your ears

Pros: Sound good, really do fold, light on the ears

Cons: a little fragile

Sound quality is the same as 30 years ago!

Overall

These on-ear phones are as good as any over-the-ear phones I've ever heard. Got my first pair 30 years ago, but they got stepped-on and broken. Got these as a gift, and am once again in stereo heaven. No fatigue at all from wearing these for hours on end!

Pros: Ultra-light, wide dynamic range, excellent bass and highs!

Cons: Volume control removed from earlier version
Review by Mediaace / (Posted on 1/20/2015)

Best by far

Overall

I've been using these since 90 when I was in the military. I bought them because of how they looked not knowing it would have the quality of sound. Every time I buy something else I always come back to these. Special!!!

Pros: light, easy to wear, compact, great bass

Cons: none
Review by dabrowhnornett / (Posted on 1/16/2015)

Beats...Dre's BEATS!

Overall

I have owned Porta Pros for many years. The sound quality is amazing and the clarity rivals that of a Bose product. They fold up nicely for storage in the included pouch. If anything goes wrong with them from normal use, you can return them for a warranty repair. Save your money from the big flashy headphones; these are the last set you will ever need!

Pros: Quality Durability Warranty

Cons: May be a bit tight during break in period

A real retro beauty

Overall

I have finally found the best headphones for me and my ears. Nothing comes even close. I hope that Koss will never change the design, as its perfect.

Cons: None
Review by Furtin / (Posted on 12/1/2014)

A gift that really keeps on giving

Overall

Received these headphones as a gift to replace old and broken Koss 35A phones. I was taken aback by their retro design but one listen to my ipod with these surprised the heck outa me. Perhaps the folks giving these knew about their reputation. I mostly use these with an ipod and my tablet, but they sound super with my stereo too. I really have no complaints as there really is nothing to complain about. Some have commented about catching in your hair, so I've fitted them for me and taped the bands with Gaffers tape. Now there is no issue and the phones are already sized for me each time I pick them up. All I can say is Thanks Koss for continuing to produce these wonderful headphones. BTW, I am a musician playing bass for 36+ years and love the bass response.

Pros: Amazing sound and comfort, durable, retro.

Cons: Pretty much none.
Review by Carlo / (Posted on 11/13/2014)

Throwback Gold

Overall

Koss has been producing these headphones since I have been alive and they are still the best dollar for dollar headphones in existence. These make $400 headphones sound like subsonic garbage. Buy these or you will regret it for the rest of your life.

Pros: Amazing Clarity, Unstoppable Bass, Built To Last

Cons: Not made out of platinum and diamonds
Review by EvilBAkeOven / (Posted on 10/21/2014)

its a real ICON

Overall

clunky old structure, hair always get caught in the head band, the comfort zone won’t stay in a place where you slide them. but.... extraordinary sound performance. Clear and bass rich I'm so happy to have this piece of history. I bought my Porta as a gift for my friend, but after I tested the piece, I changed my mind and I’m giving him another gift instead ;) I have it along with Sony MDR-V6 , I can't use them both and I can't get rid of one neither

Pros: Great sound , unexpected bass

Cons: no isolation, but it is what it is

A Year Later and Still in Love!

Overall

Got my pair a little over a year ago and still in love with them. Everything just sounds better with these headphones. They do a take a little more space when storing but you're definitely getting your money's worth. My mom loves her pair too.

Pros: light weight, durable, incredible sound

Cons: bulky storage
Review by Fern / (Posted on 9/6/2014)

You cannot beat the price and the service!

Overall

The Koss Porta Pro is the best headphone at its price range, period. Clean and crisp sound across all frequencies, not to mention the charming bass. I bought my first pair in 2004 and a 25 anniversary version in 2009. The frame of the latter broke in 2009, so I kept them in storage. Not until recently did I found out that they have a limited life time warranty. I sent my 25th anniversary version back for repair and received a brand new frame within three weeks with no questions asked. Not many brands stand behind their products as Koss does, especially considering these are budget headphones comparing with many other hi-end products.

Pros: Clear sound, deep bass, solid build.

Cons: Can feel a bit tight after wearing it for a long time
Review by ofpower / (Posted on 8/14/2014)

Best in its class!!!

Overall

Although I have seen these headphones many years ago, I only got my 1st pair in 2011. Today, I got my 2nd pair (my 1st pair is still fully working). They are the best phones in its price class, beating the competitors that might cost 2-3 times more. My favourite Hi-Fi phones comes from another manufacturer, which costs 5 times more than the PortaPro. but the PortaPro sounds very close to it and it is my "allround" phones.

Pros: Clear sound, good bass and high frequency.

Cons: Feels a bit flimsy.
Review by Andy R / (Posted on 8/9/2014)

3 time buyer

Overall

Saw this pair on cnet as a good pick for budget headphones. Liked them so much I have not bought other headphones since. I use these to listen to music while cooking, games while gaming, and whatever I need. Great deal for the price.

Pros: Flawless sound quality, light, and comfortable

Cons: None after 4 years

Bought in the early 90's and still going strong!!

Overall

This set of headphones have given many years of great service. I do replace the ear cushions occasionally but it is an easy process. I use these with my iPod, iPad and MacBook Pro.

Pros: Fantastic full range sound. Light and Comfortable
Review by California Dodger / (Posted on 6/9/2014)

Just But It

Overall

The band was catching my hair occasionally due to the design, so I shaved my head, I really do like these, I guess!? Due to the open back / ventalated design of the speakers, everyone can here what you are listening to, its a really cool feature when you want the attention and have people to ask you "What kind of phones are those, I can here them all the way over here", just so you can show them off. Not so cool when they get attention from my Prof or the Librarian. These have a well balanced sound, almost a flat line on a Parametric EQ Test.

Pros: Servicable

Cons: Has a cord like all others.
Review by Rooted Superuser / (Posted on 6/7/2014)

5 Years and Still Great!

Overall

I got these 5 years ago as a christmas present and they still sound brand new even when I use them for hours and hours every week. I've used them for everything from listening to music, video games, and working on studio recordings. A simple design and really great sound. If any of my friends ask me about headsets this is always my first recommendation. For the price it's unbeatable.

Pros: Clarity

Cons: Occasional Hair is pulled
Review by Jacob / (Posted on 5/29/2014)

PortaPro is KING...

Overall

without doubt the best sounding earphones you'll ever hear for the price. I am a bass player and have fairly high demands when it comes to the bottom end, and it has always been the portapro I turn to when I really want to listen to a track in sweet hi-fidelity. Crystal clear highs from the 20K tops. But the real cream here for me is the bass response - down to 15K without any hint of boominess or "floppiness" - just tight, well-rounded, bass. You will find the odd track or two that might need a bottom end boost, but I can guarantee this will be the source file and not the headphones. Try not to listen to anything less than 320kbps in these beauties, otherwise you will hear the limitations of compressed file formats.

Pros: Sound, Weight, Small Form Factor

Cons: Foam Ear Covers, Cord Length

Heaven on the Ears

Overall

Once you get by the body and the simplicity of the construction, these are the best ever over the ear headphones I have ever purchased. I wore them to work out and they were a trooper, except the sweat caused the sleeve to rust and then the ear piece broke. I had them for three years and I used them constantly. When they broke I sent $9 to Koss for handling and shipping and they replaced them. They are, by far, the best sounding, and most comfortable headphones I have ever owned. If there were some way to add noise cancelling to these they would rival the expensive brands.

Pros: Lightweight-comfortable-great sound

Cons: Looks - Not Noise Cancelling

Small size, big sound.

Overall

Just got my Koss PortaPro headphones in, and I thought this has to be a joke. These are dinky. The website and youTube reviews were good, but for a moment there, when I pulled them out of the package, I thought I had made a major mistake. A plain metal ribbon headband, with small speakers, that fold up into a size not much larger than a tennis ball, and a thread like cord that looks like it would be more appropriate for ear buds than headphones. Then I listened to them. I've had more expensive headphones that didn't come close to the PortaPro. Hearing is believing. Only my 40 year old Koss Pro4AA has a broader sound spectrum, at twice the price, and much more than twice the weight. Because of the weight, I wouldn't wear the heavy Pro4AA for anywhere near as long as the PortaPro. I can see why reviews online rate these as high as other brands (nameless here) that sell for three times as much...or more. Apologies for the blurb, but I'm impressed. I'm sorry now I waited so long to try them out.

Pros: lightweight, compact size, broad spectrum sound

Cons: looks flimsy, cord looks vulnerably thin. cord is occasionally too short.

Amazing

Overall

I bought these at K Mart. I tried them out on my cell phone and bought them on the spot. These cans rival the sound of my Grado headphones. The highs are clear and strong and the bass is tight. Just simply amazing.

Pros: excellent clear sound

Cons: none

Wonderful, Amazing!

Overall

I'm a professional musician and I do my studio recordings and monitoring with different headphones and speakers. I'm really surprised with Portapro for quality and strength of design and sound quality and precision! the depth of the bass and treble detail produce a three-dimensional sound which compares reality with recorded playback! These are awesome! are also so comfortable and lighter in a few minutes you forget you have them on and allows you to listen to natural sound.

Pros: Portable, comfortable, perfect sound, beautiful design and amazing price!

Cons: None
Review by Pablo Q. M. / (Posted on 3/30/2014)

Incredible

Overall

I got these for their portability. Initially I expected these to have tin-can sound, but it turns out to sound even better than my over-ear headphones! The mid-bass and mid-range sounded incredibly smooth and vocals feel so real. The highs are pretty good too, but the bass drowns it out a bit, but is easily remedied by using an equalizer to tone down the bass. These cans also have a large vertical soundstage. The only negative with the PortaPros is the massive sound leakage. Overall, I'll definitely buy these again!

Pros: Clear, Good Soundstage, Bassy, Portapro, Durable

Cons: Slightly warm
Review by Andy / (Posted on 3/29/2014)

Excellent choice

Overall

am glad to see Koss still makes these headphones. I've had mine for 10 years or more and still love them. Excellent sound quality, light weight, minimal bulk. Koss stands behind them solidly as I did have them repaired once. All other light weight phones seems to be junk, but these Koss Porta Pro are wonderful - you can't get audio this good unless you go to full enclosure type phones.

Pros: Incredible sound quality

Cons: none

Incredible

Overall

I've typically gravitated towards headphones in the $300-$500 range in an effort to find that "perfect" sound. This is the first time I've had this much fun with my music collection. Seriously Koss... great job! :)

Pros: Legendary for a reason. Comfort and sound couldn't be better.

Cons: Dated look but it wouldn't be the porta pro's without it.

Great for outdoor use

Overall

I listen to these on my long running sessions outdoors. They hold up well even during rainy weather. But I would recommend a waterproof hat when running during a heavy rainstorm.

Pros: Amazing clear sound, awesome bass, and comfortable

Cons: none really

Awesome 'Phones!

Overall

I have been using a pair of Koss TNT/88 for 25 years and went to check on replacement pads for them. I was surprised to see the PortaPros were still being sold. I almost picked them up in 1989 but got the TNT/88 instead. After reading the reviews I figured I should try them out. Turns out the choice was correct! They are one of the most comfortable headphones I have ever worn, they are lighter and smaller than they appear online. Sound quality is fantastic. Bass is awesome and not boomy, highs are crisp but not grating like on some other headphones. I have many pairs of headphones from over the ear Sennheisers, on the ear JVC's and in-ear Panasonics that I alternated depending on the music and environment, the Porta Pros have pretty much relegated them to the drawer. I love the retro look, no one around me has phones that look like mine and I think that is great!

Pros: Solid bass, comfortable

Cons: None

Big sounding little headphone

Overall

Very comfortable (important) solid bass , lovely highs and fantastic detail , really good . Look funky from side but cool from straight on. Fit under a beanie hat. I have 18 set of headphone , I cant help it and these are one of my favorites.

Pros: Great sound funky light comfortable style

Cons: Feel delicate but have comforting warranty

Overall

These super little gems have great frequency response,with minimal battery drain. Better overall performance than Bose and did I mention battery drain. I've tried them all over the past 40+ years and these are the most efficient of all. first purchased 1988. :-)

Pros: Best Power Efficient Ever

Cons: None

Great headphones!!

Overall

I purchased these from Amazon and am very pleased. I compared their sound to much more expensive brands/models. These are great especially if you consider the price.

Pros: Excellent sound and comfort

Cons: Maybe a little dated looking
Review by Adrian / (Posted on 12/25/2013)

An Evergreen Model

Overall

There's a reason why these have been around since the 80's - performance sells. Very small footprint when folded up, very convenient to carry. A key advantage to these headphones is the fit - the metal headband acts to clamp the 'phones just right onto the ears (although there is a switch to even lesser the clamping), which gives optimal bass from such a good ear-speaker seal. At the $50 price point, they are a good value, considering their build quality and sonic performance. Also, Koss is the best with a warranty - should they become damaged they will make them good again. I've had mine for many years.

Pros: Great fit, good bass, clear mid- and treble performance.

Cons: Cushions disintegrate over time.
Review by Jerry / (Posted on 12/14/2013)

Gotta Try Them!

Overall

After researching and countless online reviews/referrals I decided to give these a try. Originally got the KSC75 Clips at a local store to make sure the "rumors" were true and sure enough; both of these headphones are the real deal. A must have for anyone who enjoys music.

Pros: Sound and Comfort

Cons: None

Solid performer

Overall

I use these every day at work. Comfortable, great sound--surprisingly good for the price paid. Don't let the retro look fool you these are great headphones. Love the warranty that I needed to use once. $9 and boom! They sent me a new pair. Great!

Pros: Value price, great sound, foldable, warranty

Cons: Metal band can catch hair

I've owned a pair of these for more than ten years, and while every three or four years a wire comes a little loose or the cushions wear out the warranty helps me replace them easily and cheaply!

Cheapest Professional sound money can buy

Overall

Set seemingly cheap and out of place in design product will guarantee to surprise even the professional of the sound. This product has a lifetime warranty. I tried a lot of headset. The Koss Porta Pro is my preferred. Point!

Pros: Very clear and limpid sound

Cons: Truly none

Never heard better quality for such a price!

Overall

I was looking for new headphones once I grew tired of my various collection of ear buds. I also have a couple headphones like Bose and AKG, I thought I was fully satisfied with these headphones but I wanted something more. I looked online and the Koss Porta Pros seemed to have good reviews so I decided to give them a go. Once I bought them and tried them on I was astonished. The fullness of the sound and the clarity of instruments was unbeatable to my standards. The Porta Pros are definitely a bang for the buck and I definitely recommend them to anyone who is looking for a more fulfilling listening experience.

Pros: The 80-esque design, the comfort levels, the low price and of course the amazing sound

Cons: From time to time the headband snags my hair
Review by Karol / (Posted on 6/11/2013)

Porta Pro has the best sound

Overall

I bought my first pair about 6 years ago. Since that time, there have been several headphone manufactures that have developed better sounding headphones, but only if you are willing to spend 4X more. These are by far the best sounding headphones for the cost. They have this feature where you can adjust the pressure of the earpads on your ears. While this feature is not that important to me, I can see where this would be of benefit to some. The dynamic range of these headphones are wide enough to allow the listener to hear ALL of the music. The dynamic range of the human ear is about 8Hz to 20KHz. The range of these headphones is 15Hz-25KHz, more than adequate to cover the audible wavelength and any inaudible harmonics which add richness to sounds.

Pros: Great sound for price

Cons: none
Review by mcleanpe / (Posted on 5/29/2013)

Best headphones EVER!

Overall

Great headphones which work well with all your modern devices. iPhone, Nintendo 3DS, PSP, Macbook Pro, MP3 players, etc. Amazing sound. Tried Grado, B+W P5, Sennheisers but these are better in my opinion. Why pay more? How about version with titanium drivers?

Pros: Easy to drive, sound fantastic

Cons: No hard case available :(

I don't need another headphones

Overall

I'm a music lover and my friends too , but when I show the Porta Pro to them they went to the store to grab a pair they use the Porta Pros more than the dr dre , they liked it more they all tell me the sound is more balance and accurate with every genre of music

Pros: Everything, but most important sound, has no match.

Cons: Nothing, this are perfect

Porta-Pro is still the best

Overall

Porta Pro delivers full sound from portable music players without blocking your ears, so you can keep aware of what's going on around you. When folded they easily fit in a coat pocket or bag. I love these headphones and would recommend to everyone looking for great sound under $50.

Pros: Small, light, very compact when folded, fantastic sound!

Cons: light plastic build
Review by FK / (Posted on 4/12/2013)

Superb sound quality

Overall

Sound quality is excellent, retro look, comfortable, stay on your head when running. Just wish they were made out of better material, the plastic is a bit cheap and mine broke - not sure how/when. Having said that I will be buying another pair.

Pros: Sound quality is excellent, retro look, comfortable, stay on your head when running.

Cons: Could be made with better plastic to make them more robust.
Review by ct / (Posted on 4/10/2013)

Wow.

Overall

First impression: Wow. Second Impression: Wow. These are great phones! Full-bodied bass, thorough mids, and mellow trebs. For under $50 what more could you ask for? Their lightweight design appears cheap at first, but upon listening I am completely blown away. They're easily powered by a portable MP3 player and still provide a great sense of depth and separation instead of muddy or "heady" sounds. Thanks Koss, you have one more converted believer!

Pros: Lightweight, inexpensive, powerful, retro look, depth of sound.

Cons: Retro look for some.
Review by Joe C. / (Posted on 4/6/2013)

The single best headphones for your money on the market.

Overall

These are one of the best purchases I've ever made. I recommend them to anyone looking for a pair of headphones regardless of the price range they are looking into. I foolishly stood up once while plugged into a computer and one of the cords snapped, but the warranty had it fixed within a couple weeks. Do yourself a favour and buy these headphones!

Pros: Rugged and compact design, astounding sound quality with clear highs and deep lows, comfortable, open ear design makes them ideal for running/biking.

Cons: Visually a little out of style, but you don't mess with success.

BEST EVER

I have heard the "Beats by Dre"...they are garbage! I've been wearing these headphones since the early 90's. I am a music fanatic and I even have a crazy sound system in my car. These headphones sound like the inside of my car. The base is amazing!!!! DON'T PASS THESE UP!!

I've own these since 2000 and have traveled the world with them in my backpack! I've stepped on them and sat on them and put them through lots of torture. They were staring to give out and crack on the plastic. I'll just buy new ones!! Love them like crazy and my $325 Bose sure have collected a lot of dust over the years.

Cons: They're fugly looking

Ut Oh!!!

Overall

I've owned the original larger (heaver version) Koss headphones from back in the day! These sound very close to the older model, but with these you can hear what’s going on around you. Excellent quality set these are, unfortunately, wire is too short and while I got out of my chair, the wire was under my foot and it pulled out of the speaker (damn)!!! But i went online and ordered another pair! Immediately...cuz there aint nothin better...lol

Pros: Best Sounding Headphones for this price! Most Definitely!!!

Cons: Wires are too short! THAT’S ALL!!!

The best

Overall

So basically my Bose OE died on me, thinking that I am not worthy of spending expensive headphones, I bought these. I never looked back since. These are the most awesome headphones that I have ever bought. Light, great sound, great highs and low’s, even base! 2 cons, it’s leaking pretty bad. but if your seatmate does not mind, you’re good to go. The second one is the build quality isn't that +A. Plastic feels gonna snap. Best PROs.... LIFETIME WARRANTY! Enough said.

Pros: Light, Awesome sound, clean

Cons: feels gonna break within a couple of months
Review by Gino / (Posted on 2/13/2013)

Simply the best you can get!

Overall

I have tried almost all headphones for professional use and this small headphone is excellent compared to its competitors. I use them for travel, in the gym and even in the studio I have some pairs lying around. The bass is really incredible compared to much more expensive headphones.

Pros: Sound, portability, design

Cons: None
Review by Morten / (Posted on 2/2/2013)

One of my favorites products

Overall

I bought my first set of Porta Pros in the late 80's. I kept them until I accidentally shredded the cable when it got caught on my leg while on the stationary bike. I was shocked to find that they were still being made. I went out and bought 2 pairs. Since then I have owned other more expensive (cooler) headphones, but none that have sounded as good or was more comfortable than my Porta Pros. I still use them in the gym 3 to 4 times per week so I tend to wear them out every 3 or so years. The great sound and comfortable design make working out way more pleasant. Thanks for maintaining such a great product for a fair price over such a long time span.

Pros: Consistancy

Cons: Used to be cool
Review by Ed / (Posted on 1/20/2013)

one word.. great!

Overall

Great sound for that price! A little bit bassy and high frequencies are crisp but not at the level of the KSC75. Comfortable enough but mechanical is weaker than other compact headphones I tested. Anyway a very good choice for mobility.

Pros: sound quality

Cons: not so robust as others

My ears are happy

Overall

I cannot go out with listening to music, and I've gone through a lot of on-ear-headphones that have superb sound quality, good build, but what has always ticked me off is how they hurt my ears after hours of having them on. I just bought these this morning and I've had them on for about 4 hours now and my ears still feel nothing. I absolutely love it! Good build quality, excellent sound, excellent feel! I am now a fan of Koss!

Pros: Excellent sound quality, Very compact, Feels good to wear, Ears won't hurt even after having them on for hours

Cons: My hair tends to get stuck at the metal band but it rarely happens

Great Reliable Headphons

Overall

I've been buying these since the 80's and have always found them to sound fantastic and easy to carry around. Also, they truly honor the warranty whenever there has been a problem. Buy these!

Pros: Great sound and potability

Cons: Like most portable headphones, they break at the plug.
Review by Charlie Mingus / (Posted on 12/10/2012)

FANTASTIC sound, mechanically weaker

Overall

The Porta Pros acoustic quality is proverbial. For instance, anytime when somebody tries to argue with me, that you "cannot" hear "any" difference between, let's say, 160 and 320kbs mp3, I use Porta Pro to easily prove them wrong and to let them experience the real difference in sound quality by themselves. Before I voice here my concerns about mechanical sturdiness, I must say that I do abuse my gear a lot coz I mostly use it when running or travelling. My first Porta Pro I bought in early 90's. They cost me a small fortune and lasted 10+ years. Even long after all ear cushions and the supportive pads were gone, I still used them for the fantastic sound they offered, which beats any open and most of closed earphones with unimaginable ease. I was pleasantly surprised to see in early 2000s how much the price dropped. Then I was quite disappointed to see they also don’t last what they had used to. The "25th Anniversary" black edition lasted less than a year, and the replacement too. I find the firmness regulation mechanism the weakest point even with the first pair I bought in 90s. This hasn’t changed - that is still the first thing that breaks down in few weeks' time and from that moment on, the earphones are in "firm" mode. Since usually you have shorter time to listen available than the time which it takes before your ears to start hurt, I don’t find this as a big problem. What I do abhor, however, is the poor quality of cable which leads to 3.5mm jack. The 90's model lasted 10+ years. The cable was soft and had rubbery feel. The two pcs which I bought a year or two ago had a cable which had a more plastic touch and which also is stiffer. Both broke in the connection between the jack and the cable, and as a result the sound only went into one speaker. This happened only after few months of use. Of course, the earphones are very affordable but still. If you buy somewhere where the so-called "life-time warranty" is applicable, do keep the receipt. It might come handy sooner than you might expect. Also, what I m going to do w my next pair is to wrap an inch of cable above jack with black duct tape to move tear and wear from the connector part to more flexible part of the cable. Professionally I have been involved with companies who outsource their production from developed countries elsewhere. Sometimes locally sourced components do not have such good quality, or, in order to save a cent or two, a marketing decision is made to use "very slightly" lower quality parts for the not-so-critical components. I know that 1990's are gone and it will never be back. But if you ask me, I would MORE THAN happily pay 50% more and get the overall mechanical sturdiness to which I got used to 20 years ago. However, all this is "rich men's problems". Like complaining that the seats in new Ferrari are slightly less durable than the seats in the older one. It is still Ferrari! :-) If you have never listened to these earphones, try them and you will hear by yourself.

Pros: Sound (especially basses), lightweight, foldable

Cons: Regulation of firmness, jack cable

Porta pro time machine

Overall

What a throw back. I originally picked up a pair in 1990 while in the military. I thought they sounded good at that time. I had one of the first portable CD players and enjoyed listening. I really used this pair to death and I purchased another and then moved on to ear bud headphones. So I was online and found these again and said, let’s try them out again and see if I still like them. I gotta tell you, this is one of the best deals on the internet. These sound better than any ear bud and most over the ear phones. You gotta try them. If you don’t like them, then just return them. In the end you will keep them.

Pros: Great sound. Comfortable

Cons: Easily broken

Koss PortPro Headphones

Overall

I just purchased a pair of Koss Porta Pro headphones after reading the review and ration on CNET. I was a little skeptical $50 headphones that sound that good, too good to be true. I was not happy with my Aviator SkullCandy's ($140) so I was looking for a new headset for X-Mas.I purchased the Koss at K-Mart of all places because they carry them in stock. I put the Koss on and immediately I could tell the difference these headsets are GREAT, very good bass, clear crisp sounds. I am very happy with my purchase.

Pros: Light weight, superb sound and clearty

Cons: fold better
Review by Cesar / (Posted on 12/5/2012)

Excellent sounding headphones, great value.

Overall

Like someone else here, I had been wanting to grab a pair of these and found them, of all places, in a K-Mart. Couldn't resist buying them. Look, for $40, you're not gonna find a better sounding pair of phones...and you may be hard pressed to find a pair that cost twice as much, to sound as good as these. Get them, you will be glad you did.

Mind-Blowing

Overall

I've had these headphones for several years now, and my brother owned them for about a year or so before he gave them to me. My family is a bit on the audiophile side, so I've had many different headphones to compare these to--notably Koss DJ100 and Sennheiser HD555. In all honesty, I may actually prefer my Koss Porta-Pros over either pair. Being someone that tries to achieve the best listening experience (on a budget, of course), I have listened to many, many headphones. These headphones have always seemed to conquer even the high-end $150+ headphones, and, needless to say, they crush every headphone in its price range. All of my friends are skeptical of them because of their classic (and kind of cheap) appearance, but their face says it all when I have them put them on. It's pretty funny watching people's reactions when they realize that $50 headphones are miles ahead of their $200 headphones in terms of sound. My only complaint is that they start to make the tops of my ears sore after wearing them for several hours on end; however, that's to be expected with most headphones. Their light weight also means they're kind of flimsy, so be careful handling them. I would go throwing them in your book bag or letting them fall onto the floor. They break very easily. However, if you care for your headphones as you should, they can easily last you an upwards of 5 - 10 years. If you're looking for headphones with high-end sound, but not the high-end price, these headphones are perfect. They sound amazing, feel great on your head, and your wallet will appreciate the price.

Pros: Incredible sound quality, Affordability, Lightweight

Cons: They tend to become uncomfortable after 2 - 3 hours of constant wear.
Review by Brian / (Posted on 11/16/2012)

Outstanding Value

Overall

I have 2 pairs of the Koss Porta Pros. The y both sound fantastic and I have not found any others that come close to the sound and comfort. My kids have managed to snap one of my Porta Pros twice by mis-handling them and I have managed to damage the cord on my other set when I snagged it on a chair, but on all 3 occasions my Porta Pros were repaired under warranty within 2 days (at my local reseller here in Sydney Australia). If I ever lose these I would head straight to my Koss dealer and replace them with the same model.

Cons: Not the most stylish headphones

PORTA PROS

I went 12 years trying to find these headphones, not thinking to go online. I lost the one’s I purchased from the exchange when I was on active duty. Then my car got crushed when I was in an Atlanta, GA hospital. I finally found them in, of all places, a K-Mart in North Augusta, SC. Do you sell an extension cord for the headphones? Koss Corporation: Yes, Bryant we do sell extension cords. You will want to check out the accessories section of our site for your options!

Pros: Best Sound in the World

Cons: The cord looks like it could break easily

Still have not found one better

Overall

There are 3 pairs in my household. Put these headphones on and you feel as if you are right in the party or in the studio monitoring the recordings. You will hear sounds in the music that you didn't know were there. It has one of the best bass response of any headphone phone in its class, and headphones that cost $199 and $299 plus. Friends with the fashion statement headphones are always impressed with the KOSS Prota Pro when I let them have a listen. Some of them even feel ripped off. Monster will do to headphones what they did to copper cables. Remember those $100 HDMI cables, oh yeah, same crooks make beats. Keep you the good work KOSS. It's all about frequency response and designing a speaker to produce it accurately.

Pros: Bass, clarity, overall frequency response

Great Sound

Overall

I have two pair. These are some of the best sounding headphones you can find in a compact jogging size. Yes even compared to Bose and other premium brands. They are worth more than they cost. The metal band sometimes pulls my hair, and you won't win any sleek ear bud headphone looks contests because these are over the head supported, but they won't fall out your ears. These are winners. I'm so glad Koss still makes them.

Pros: Great Sound
Review by DetroitJake / (Posted on 10/3/2012)

Fantastic Product

Overall

I've had my Prota Pro's since 2007. There still going strong and do create the truest sound you would get from a pair of headphones costing $200.00+. Though they are delicate and can break easily if not properly handled. I would say that after owning them for 6 months, they did lose sound in one ear at one time and I had sent the back for repairs. Koss sent me a new pair super fast. And you can't beat their Lifetime Warranty on all their products with a no question ask. Really a great product and great company to do business with. Seriously.

Best of the Rest

Overall

I bought these about three years ago from B&H back East and the price included shipping. They are better than I ever expected for the cost. I use them while working out or just relaxing. My mother (86) bought a pair at my suggestion and she loves them. She uses them to listen to music and books on tape. They are the best of the rest and save you $$$.

Pros: Great Sound - Terrific Range - Lightweight - Comfortable - Well made

Cons: Don't block out outside sounds

You'll be shocked at how good they are.

Overall

I've had my pair since 1996 - that's 16 YEARS, and they still sound amazing. I've tossed them around, I've replaced the foam around the ear pads -- they dry out like any foam after 10 years, I've had my little girl yank on the cord -- and they still work flawlessly. BEST HEADPHONES I'VE EVER BOUGHT. HANDS DOWN. The only thing I can say negative is that the foam pads on the head strap (I’m sure that's not what you call it) came off after several years, but they don't really serve much of a purpose and still fit great without them. I'm sure Koss would replace them if I sent them in since they have a lifetime guarantee, too. They also are a little "old school" looking as they're open ear, but for some this is actual style points and not a negative. All in all, there is no way to understand just how rich and clear these things are until you put them on your head. I've worn $100 over the ear professional headphones that don't touch how amazing these things are. I'm constantly putting them on heads of my skeptical friends and watching their eyes light up with amazement when I hit play on my iPhone. BUY A PAIR. YOU WON'T BE SORRY.

Pros: Rich bass, comfortable, durability, lifetime guarantee

Cons: Design looks dated, foam pads on head strap fell out after several years of use

Perfect Headphones

Overall

I own one pair since five years and I still love the great sound. The only con is that the headphones come off when you do not put them in a box for transport and then you cannot tell which is the right and which is the left one. I have tested them against some 25 other headphones like Sennheiser and Monster but these are to my ears the ones with the most realistic sound. You can spend 5 times more money but don´t get better sound. Only my In-ear Shure SE535 produces even better sound but is less comfortable and cost 10 times as much. And you cannot compare closed to open headphones. Highly recommended.

Pros: Natural, distinct sound, comfortable fit.

Cons: none

porta pro

Overall

I bought this from your distributor in Vietnam in Ho Chi Minh City. It is fantastic, better than my brother’s PX100II which he paid more for!!

Pros: fantastic sound

Five Stars +

Overall

This headset has the best sound reproduction of any headset that I have owned, including much more expensive, full-sized ones. The frequency response is excellent up and down, but the bass fidelity is superb. Some other headsets emphasize bass response and end up with a very muddy sound, but Porta Pros reproduce the bass clearly and naturally. The fact that it is portable is just a big plus. I have taken these everywhere. I use these on my home stereo, my tablet device while watching or listening to streaming media, my portable radio, my iPod, and for in-flight entertainment instead of the cheesy headsets that the airlines sell you. In all cases, I have been 100% satisfied; it is no wonder that they have been around since 1984. If Koss ever announces that they will stop making these, I will buy half a dozen so that I will always have a pair.

Pros: excellent fidelity; portable

Cons: None

Excellent

Overall

I bought these yesterday in Berlin-great sounding, doesn’t tire the listener out...even with other genres. The Perfect buy for me. And I tested it against AKG, Beyer Dynamics, Sony etc.

Pros: Price, Comfort & Sound

Cons: Colour
Review by Frankie Flowerz / (Posted on 7/24/2012)

Amazing

Overall

Ignore the way these look, unless you like 80s style gear that is primarily plastic. Despite the way these look, they are amazing headphones. I have some Bose on the ear phones that are blown away by these Porta Pros. The sound is comparable to phones that cost three times more. In addition to this, they are under warranty for life. So, forget about the plastic frame. Koss will stand behind it. However, it the many years I have used these, for working out, riding my bike, and just listening, I have never had a problem. Trust me. You will be amazed by the sound quality of these headphones.

Pros: Sound, Lightweight, Comfort

Cons: 80s Style

the best head set ever

Overall

The song is nice and they are loud plus they have held up to me so they are durable.

Pros: Nice sound and portable lightweight, strong

Cons: none
Review by T79B / (Posted on 6/27/2012)

Quite simply the best !!

Overall

These headphones have to be experienced to be believed. I listen to jazz, exotica, vocalist and electronica. The first time I used these I knew my other phones were going to be second in line. I even tried them with phones costing much more...the winner every time was the PortaPros. On many Internet short lists of best headphones of all time these are there. Look for yourself. PortaPros are a classic that has not changed over the decades (thank goodness)

Pros: Full natural sound, very comfortable, collapse

Cons: My expensive headphones are gathering dust

Koss PortaPro

Overall

They produce a lot of bass (nothing major, although I do like my AKG's for the fact that they are flat and can be tweaked with the computer settings. Bass isn't so bad though. Great buy!

Pros: Very powerful, great sound quality, very comfortable (don't even notice they're on)

another world

Overall

I'm not an expert, but I enjoy hear music, in a variety of styles. I did not have knowledge of terms like hi end or audiophile, until try a friend's Porta Pro. The word, at that moment, that I exclaimed using those phones for the first time was "funny sound", I could experience a new level of entertainment at listening music.

Pros: Amazing sound, easy to use.

Cons: Price in Brazil
Review by Marcos / (Posted on 6/19/2012)

Definitely the best headphones under $100

Overall

See Pros and Cons.

Pros: Still one of the best sounding headphones after all these days. Extremely balanced-sounding with full and extended lows, warm and natural mids, detailed and smooth highs. Very well-built even though it looks flimsy.

Cons: NONE... Well, the price went up a bit in the last few years.

Best Headphone value out there

Overall

I bought a set of these at Ft. Carson back in 1990 before shipping out for Desert Storm. I was blown away by the deep base and crystal clear high's. For the next 22 years they delivered incredible sound until I accidently stepped on them and broke them the other day. There was no doubt about what I would buy to replace them. And after 22 years, they still cost the same price I paid for them back in 1990. That's amazing!! KOSS ROCKS!!

Pros: Everything

Cons: None

Porta Pro On-Ear

Overall

Excellent headphones for the price. Nice fold-up design. Produces very accurate tones. I've had mine since 2007. Still working perfectly. Unfortunately, the design and construction is pretty delicate. You just have to be careful with it. I did lose sound in on ear about 3 months after I purchased them. KOSS replaced them really quick. So far no problems. I should have purchased the other model that I think they discontinued that had a noise cancelling device attached to it or was it an amplifier with volume control. Can't remember. It too got good ratings. Anyway, extremely satisfied with these light headphones. They produce some incredible bass. Also love the life time warranty on this phone too. With the lifetime warranty options, I'm set for the rest of my life.

Pros: Sound Quality

Cons: Delicate construction

The Best Portable Headphones Ever

Overall

I have owned Koss Porta Pros for over 20 years. The sound was amazing then and I haven't heard any phones that will touch them in all around sound. The Bass is strong and TIGHT, not boomy. You can hear every instrument including voices. Every time I let a friend listen to them they are blown away. I own 5 pairs. One each for my spouse and I's MP3 player and one for the computer. I use them ALL the time so I have 2 spares in case of any breakage. I then send them back to Koss with $7 for a new or repaired set. They are very durable so that doesn't happen often.

Pros: Amazing Natural Sound through the whole sound spectrum.

Cons: None

Best headphones in price range

Overall

These on ear headphones are the best and most comfortable I've listened to for under 150$. The warm, deep and detailed tones are fantastic. The lightweight design and cushy pads don't cause any strain on my head. Listening to them is easy and recommended for long periods of time. The one thing that keeps them from being a perfect product is the thin cord is easy to tear at the jack; the cord is not very durable overall. If you have an MP3 player or listen to music through your phone these are a must have.

Pros: Very comfortable, Great sound quality, good price

Cons: Small cord easy to break

Top Quality Headphones

Overall

I have been a proud owner of this headphone for over 15 years and still have the same super sound I got the first time I used it. Base, middle tone, high tone, everything super. Excellent product. Price also is ok. I can only recommend

Pros: Everything! Best sound, Comfortable, Lightweight, Quality

Cons: none

Super Sound, Low Price

Overall

I love these headphones and use them every day. Got mad when the second pair was broken, but I got a new cord from Koss themselves. THANK YOU KOSS FOR MAKING BEST HEADSETS EVER (LOVE ALL OF THEM)

Pros: Comfortable, easy to travel with, low price and good sound (the bass can go really low) and of course really good service if you call Koss. (Warranty for the rest of my life)

Cons: Had two of them and both have broken, but I got new cord on the second one.

The One and Only...

Overall

What can be said about these headphones that has not already been said in the 25+ years they have been in production? Well, my girlfriend thinks they look silly... And that for some odd reason makes me love them more. Out of few phones I currently own, I always find myself reaching for these. With the wonderful bass and full bodied sound comes the whole "Porta Pro Experience". - First you try and squeeze them out of the tiny bag that Koss has provided. - Then you unroll, unhook and unfold them. - Next comes the pain of adjusting them on your head as they rip hairs out (surprisingly gratifying). - The plug, that Tiny little plug now gets placed into whatever devise you have waiting for them. - Finally, the sound, you forget just how wonderful it is almost every time as it hits your ears. Heaven. Thank you Koss for this gem.

Pros: Comfort (Once On), Warm Sound

Cons: Hair Ripping, Short Cord
