These sound (and look!) so much better than the more expensive headphones I had previously bought. The sound is rich and warm, and voice/video calls are crystal clear. I use these for both music and calls all day long, and they're wonderful. The only ding against these is that they can get tight on the ears after a few hours—especially if you wear glasses. For the price they cannot be beat.

My favorite headphones!
Overall
I own 3 expensive headphones (AKG & Sennheiser). I saw an ad for the KPH30i and bought them, as I found my expensive phones hot, uncomfortable and difficult to use in bed. Wow, from the first listen I was hooked on these Koss phones. I compared them to my other phones, and liked these Koss phones best. First, they sound balanced from top to bottom frequencies, with an articulate midrange. These phones actually present an accurate soundstage! They're comfortable, and I can listen for hours without fatigue. I've purchased a second pair, and find the KPH30i to be my go-to phones. I highly recommend these phones! These are the best bargain in high end audio!

A warm and natural sound.
Overall
And a good reminder that headphones do not have to be fancy or expensive to sound decent.

Comfort, sound & price
Overall
Very comfortable light weight headphones with great sound for 30 bucks - the flexible earpiece mount is comprised of an elastomeric material and patented by Koss - US10136210

Once again from Koss, amazing value!
Overall
I have the KSC-75s and I love them. After seeing a review I thought I'd also try these out of curiosity.
Much more comfortable than I thought they'd be, as I expected to have to open up the headband a bit. No need and I'm 6'3" with a large head.
Initially they are a little 'warm' sounding and lacking the top end sparkle, but a simple bit of EQ and they come alive.
Deeper bass than the KSC-75 and possibly a little less detailed, but altogether still an absolute bargain.
Forget your Sennheiser HD25s and the B&W series. Save your money and buy these!

Smooth Warm sound but lacks the high frequency details I love.
Overall
I love the sound of KSC75 but not the slip over ear design. Some will love the smooth warm sound of the kph30i, but I need the high frequency details that the ksc75 has and these cant do that. The bass is boomy in the mid bass range. Koss please please do a version. Of this head phone with the titanium coated ksc75 driver in it and you will strike gold..

Stunning Performance for $30!!!
Overall
Purchased these on a suggestion from a audiphile friend at audiocircle.com. I was very aprehensive, but $30 is not much money to try something new. So far these new KPH30i's have made me smile more so than with a $1000 pair of Beyer T1's! They are light, fast, great sounding, natural, have an ability to dive into the details of a song...so lifelike. Lars Erstrand, Jazz at the Pawnshop. Larry Carlton "Discovery" have never sonunded so good....absolutely full of Koss Magic!! Thanks for such a sweet set of headphones that dont break the bank!!

Great performance for the Price!
Overall
I got these and the philips shp9500 to test them out and I ended up returning the SHP9500. The sound quality is almost the same with the KPH30i been slightly more muddy but with more bass. I couldn't justify spending $50 more for the SHP9500 compared to the KPH30i. Really happy with my purchase. I use them almost every day for Gaming on my Computer for about 2 or 4 hours gaming sessions and then to watch Youtube as well and Youtube Music.
Highly recommended.

I just received the headphone and I’m in love!
Overall
I have many headphones and even though I’m not the expert audiophile person, I love music and I always listen to music when I work on my professional as an artist. I always use headphone for a very long time. This is the first Koss headphone I decided to get because how nice of the vintage look, somehow it’s really charming to me. The sound quality and bass is absolute outstanding. I just have to share that I love it !
