Great sound, only lasts a year

Overall

Simply love the sound quality, and the comfort, which is why I keep coming back to them. But after a few pairs, it's clear they don't last longer than a year for me. Even without rough handling, after a while the sound stops coming to one ear, first intermittently with jiggling, then altogether.

Cant live without these!

Overall

Great sound, very comfortable. Would like to see ear bud replacements easier to put on. Sometimes they dont fit right and become deformed. Other then that, GREAT PRODUCT.

The best choice for bikers

Overall

I commute on a motorbike and have been using Koss Plug for years as it has been such a saviour for me. The plugs don't hurt my ears when I am wearing the helmet, and provide excellent sound and outside noise insulation. I listen to podcasts, audiobooks, Spotify while on the road as well as in the office and never have to turn the maximum volume on my phone. The only problem is that they don't last long enough in this harsh environment so I have to replace them once a year or so, which is still a good term considering the amount of usage and low cost. But I only replace them with a new pair of Koss Plugs, so thanks Koss for not discontinuing them and keeping price down!

Excellent sound

Overall

I love these headphones! This is the second pair I’ve ordered. The sound is excellent and the price is too! I have one for home and one for the office.

The best you can possible get!

Overall

I bought my PLUG last year and I couldn't be much more happier! At first, it takes awhile to get used to the cushions, but after two/three days of listening you will feel comfortable enough to wear it for as much as you want. The sound quality goes beyond, very solid, incredible bass sound (you won't need to increase your volume much to hear a bass instrument, put it in the minimum and you'll hear it well!) and great outside noise isolation for great price!

Best headphones for long periods of time

Overall

I've owned on-ear, over-ear, and in-ear headphones from most of the top brands. Some of them cost over $400. These are the most comfortable headphones, and the only ones I can wear for over 4 hours strait (I'm a developer) without feeling any discomfort. I love these!!

You Can't Beat These

Overall

I am now on my 3rd pair of these in a span of 11 years. These are the best set of earbuds I have ever owned. I have only replaced them due to either misplacing them or accidentally pulling a wire loose. I wear them on my motorcycle, on the lawn mower, on my bike or just relaxing in my chair. The bass is perfect (for me) and the foam forms to my ear canal blocking out all outside noise. For the price and how robust they are you aren't going to beat them.

The only pair of earbuds that do what they are supposed to do!!!

Overall

I am a professional sound engineer and i am using this pair of earbuds for almost 10-12 years, to listen music while exercising, traveling etc.

What i am looking for from a pair of earbuds is to be able to loudly play music, so they can give me that vibe i need for exercising and to isolate me from external noises. I tried many earbuds but this one was the only one which delivered the sound without distortion or without be burned in a week. I also used it once in a club that i was working as an in ear monitoring solution for the musicians, and they accepted it without any complaints.

The frequency response misses some high frequencies, something that can be easily corrected through some equalizer, which almost all the music players have.

This is the third pair i bought in the 10 years of usage and every time i had problem it was because of the wire, which tends to be cut, at the strain reliefs either near the earbuds or near the plug. Maybe if it was a little bit longer this could be avoided. Anyhow, i am more that willing to spend $15 every 3-4 years for a new pair of earbuds which meets all my requirements :)

I would also be very pleased if they could upgrade it by adding a microphone so it could work as a hands-free, since because of the sponge, which does amazing job as noise canceler, is a little annoying to take it out of the ear and put it back in every-time the phone rings.

Definitely recommended to people that seeks for quality sound at high volumes.

Thank you very much KOSS,

simply amazing

Overall

these are the best earphones i have had in my entire life, i tried several earphones from myfriends which usually cost about the same price, but when i tried these, my mind just exploded, amazing bass, amazing treble and i can't hear anything, including myself. i would recommend these to anybody.

Overall

I can enjoy my music,and It blocks out ALL outside noise.
LOVE LOVE LOVE these !!
Can't hear my annoying roommate at all.

Thank you Koss

Foam plugs is the best idea ever!

Overall

This is most amazing headphones I ever have. Period. Foam parts works and feels really good. No more ear pain due wrong in-ear part size or form. No more strange sounds because of one of the plugs fall off partly, or even just fall off. Once I got my first koss plugs I've turned down volume on my player from 80% to 15%. Listening classic orchestra. In subway.

Pros: Nose cancellation, very comfortable, amazing sound

Cons: as all headphones - cord
Review by Nc / (Posted on 4/8/2015)

Happy to have them!

Overall

I have used a pair of these for the past 4 or 5 years as in-ear monitors while playing drums. They work great to block out too much drum and cymbal noise while I'm in a drum booth. The foam seals your ear canals well and is very comfortable. I highly recommend them. For the price you can't beat them!

Pros: Sound great, low cost

Cons: cords are a little fragile if you get too rough with them
Review by Marshall Rinker / (Posted on 2/12/2015)

Great earbuds

Overall

I love these! Koss has always been great and they don't disappoint. These have great bass, not like normal earbuds at this price. That's another good thing - the price. Don't pay hundreds when you could just get these.

Pros: Great sound, great bass, memory foam is cool

Cons: NONE!!
Review by jerff / (Posted on 3/6/2014)

Great inexpensive phones.

Overall

I've used sponge ear plugs for years so putting these in is not an issue. They have to be rolled tight and held while they expand into the ear canal. Once in, they stay very well and I think this enhances the sound. The wires are very thin so they feel fragile but so far this has not been an issue. Sound is a bit bass heavy although treble is still very good. I love my KOSS.

Pros: Light, comfortable, and fantastic sound

Cons: Wires are very thin
Review by jjohn / (Posted on 11/29/2013)

Isolation and bass!

Overall

This is my second pair of these with the first being about 10 years ago. I had the standard pair that comes in the box with the phone. These are so very much better than the free pair and a lot better than the Panasonics. The noise isolation and bass cannot be beat at this price. It has to be the best value anywhere. I can't believe the increase in quality you'd get with a $50 pair would be worth it. Get this pair and you won't be disappointed. Perfect for the gym and watching movies on a tablet/phone.

Pros: Noise isolation, really good range, comfortable foam

Cons: Seem to tangled easily, used to come with more foam ear plugs
Review by Kosser / (Posted on 10/24/2013)

Amazing

Overall

I use these in the new york subway system, and they cut out nearly all of the noise. Other earphones force you to raise the volume to beat out the rumble and roar, and some don't succeed no matter how loud they get. With these, I can hear perfectly with the volume on 1 (or 2, depending on the song). When I am walking home on the street, I'm completely in the world of my music, and it makes me so happy. Comfortable, high quality sound, low price, noise isolating. This is all I want out of a headphone.

Pros: superb noise isolation, comfortable, great quality

Cons: wind whistles through the vent holes, a tapping on the wire is heard in the headphones
Review by Zo / (Posted on 9/12/2013)

Simply Amazing

Overall

I wanted non-expensive earbuds/headphones. Almost all the reviews said this was great. And it is. I don't regret buying it at all. Thank you, Koss, you did it again.

Pros: I hear every detail & looms great & fits great in my ear.

Cons: There is a bit much bass, highs sound a bit low. Lowering the volume might help.
Review by Arnold Scott / (Posted on 8/17/2013)

Love 'em!

Overall

Love these earbuds! They are very comfortable (and my ears are picky about what they'll allow me to stick in there for an extended amount of time), the foam conforms to your ear which has the added benefit of noise isolation and improved sound conduction. They have a nice beefy sound with good clarity. I would like to have a case for them, as I have had a pair go bad because of carrying them in my pocket. I would also love to see a cell phone version with a mic built in.

Pros: Comfortable, great sound, isolating, cheap!

Cons: Don't yawn or eat with them, cuts off sound
Review by Josh / (Posted on 7/25/2013)

Good Sound for the Price

Overall

Great sound but does not include a case so I use an eyeglass case to store them in my gym bag. They will last a long time if you don't tangle the cord so you might need to find a case or something if you use them at the gym!

Pros: Deep Bass, Mid Range and Highs!

Cons: Wish they would include a case
Review by pwh007 / (Posted on 6/11/2013)

THE best

Overall

This is definitely the best earphones I have EVER come across. They fit in your ear firmly and comfortably, and sound amazing.

Pros: comfortable, very good sound isolation, great performance

Cons: none
Review by rode / (Posted on 4/3/2013)

Best value

Overall

Beats out anything else in this price range. If you are thinking about getting a cheap pair of those 5 dollar pieces of crap sold in department stores in bulk, or those kinds that come pre-packaged with mp3 players , consider just spending a bit more and experience these.

Pros: Amazing sound quality for the price

Cons: Durability isn't as good as some of the others on the market, but these are infinitely superior in sound quality.
Review by Voxe / (Posted on 1/26/2013)

excellent value

Overall

I travel on airplanes a lot. The excellent fit of the foam cap in my ear canal blocks the sound of the jet engines as well as crying kids. I have tried other brand name ear buds that are much more expensive but do not deliver the sound quality I enjoy with my Koss buds. Thanks Koss.

Pros: Frequency range, comfortable, inexpensive

Cons: Short cord
Review by Deck rat / (Posted on 12/23/2012)

My Favourite

Overall

That one is my favourite earphone. It's a little bit better than Spark Plug. It's king of the price / performance but I'll try KEB40.
Review by SertacAygun / (Posted on 11/11/2012)

Absolutely amazing

Overall

I have been using these headphones for about 6 months now and their performance is amazing. These easily beat out a pair of $150 noise canceling headphones I bought a few years back. Best deal in headphones I have ever made.

Pros: Sound, Price, Comfort

Cons: none
Review by Chris / (Posted on 10/24/2012)

Great for the money

Overall

These are the best ear buds I have ever had. I have been using them for years. Unlike the others, I do not have any problem with the ear cushions as I use them daily in the yard, working out, skiing and snowboarding, and most importantly - on airplanes. I find that I break the wires before an ear cushion will wear out (call me - I have dozens of spares). I find the sound is superior to any, I repeat - ANY other ear bud product out of the dozens I have tried over the years.

Pros: Good sound

Cons: durability
Review by Wreckah / (Posted on 8/28/2012)

The best there are

Overall

I've been using these for years. They block out of a ton of sound while delivering powerful bass tones. For train and plane rides they act like earplugs. For my work in the office they keep me in a quiet cocoon - sometimes the music stops but I just leave them in and forget to start the music up because they are so peaceful and quiet! And they are so tiny and inexpensive compared to other headphones boasting noise isolation and big sound. Can't go wrong with these.

Pros: deep bass & sound isolation

Cons: none for me
Review by bandmate / (Posted on 8/20/2012)

Great for Working Out

Overall

These headphones are excellent for working out. They are lightweight and the expanding foam plugs stay in your ears, even when you are sweating. For the money, you can't beat these headphones. They will break after some heavy use but I have found that a pair lasts me about 1-2 years and that is using them on a regular basis, gym workouts, running, yard work, etc.

Pros: Cheap, lightweight

Cons: Will break after heavy use
Review by Rick / (Posted on 8/18/2012)

Best "Cheap" Earphone Ever

Overall

I put the word "cheap" in quotation because they certainly don't sound cheap. In the $10-30 price range they can't be beat. The sound quality is reminiscent of earphones that cost three times as much. The bass will satisfy those who enjoy punchy bass, but it is not offensive to those who want even response. They respond well to EQ. The tips wear out rather easily, but are easily replaced. By that time you would have gotten your $15 out of them anyway. I picked them up as a temps while I waited for my Klipsch-s4s to arrive, but those have since quit on me and the plugs remain strong. I think I will just stick with these and my ATH-M50s.

Pros: Good sound quality, (mostly) Even response, Comfortable

Cons: Tips wear out
Review by Andrew / (Posted on 6/13/2012)

amazing

Overall

Great set of earbuds.

Pros: Soft to the ear, fantastic sound quality, brings out just about every nuance of sound.

Cons: Cord should be a bit longer
Review by Cass / (Posted on 6/11/2012)

Amazing!

Overall

If you are looking for incredible bass response and great overall sound on a budget then these are the earbuds for you. I absolutely love them and I can’t wait to try the iSpark and pathfinder models next. Best $15 headphones (including full size) I have found yet. They even beat many much more expensive models from other brands. Great job Koss. My only dislike was that after a few months of HEAVY usage, the foam pads wouldn't stay compressed long enough to get in my ear. I will say that I put them through serious usage and they even got wet a few times. The problem is easily and cheaply remedied with the replacements offered by Koss. Thank you Koss.

Pros: Excellent bass response, comfy fit, snug in ear, crisp highs, great mids

Cons: Can be tough to get in the ear after a few months
