WOW!!!
Honestly I'm shocked. These headphones sound amazing. Incredible resolution, instrument separation, and clarity. It's been a while since music has been this fun. I ordered some Yaxi pads to go with mine and slapped on an EQ from the AutoEQ project on Github. These are probably my favorite headphones I've ever owned. Incredibly light and comfortable while sounding phenomenal.

I couldn't believe the quality of sound I was getting out of these old-fashioned headphones.

I had a pair my late grandad and Mum got me Koss headphones similar to these when I was very little for my portable cassette player. But over the years they went missing. But buying this has been the best decision I've made, they sound fantastic and even better than I remember, the bass is punchy and mids and highs are clear but not overpowering, simply better than any other headphones I've used in a long time. Comparing to my very expensive Sony's I very much improve the sound quality on these. You won't regret your purchase and if you want them wireless, get something similar to the FIIP BTR5's.

I had insanely high expectations for these and they surpassed them 10 fold. At such a low cost you literally have nothing to lose

I wanted a lightweight & comfortable, affordable, yet great-sounding pair of on-hear headphones to sit at my desk (not travel) with. Fortunately, Koss came up in one of my many searches and I suddenly remembered my very first pair of headphones for my very first stereo back in the late 70's. They surprisingly blew away all the competition back then, even Pioneer, Panasonic and Sony headphones. Sounded like you were right in the concert hall! So I looked at all the latest offerings by Koss, and really appreciated the long review for this pair by the top reviewer 'Ender'—comparing different models of Koss & other headphones. (I don't have time to be an audiophile, I just want to enjoy my music collection in iTunes while sitting at the computer). I immediately ordered these headphones. I knew I would also want to extend the cable, but waited until after they arrived to see the size and types of plugs they were fitted with. (The Q&A for this product in regard to that was too technical & confusing to follow.) These headphone did not disappoint! They have that great Koss sound, with a comfortable lightweight band on my head, which gratefully doesn't get snagged in my thick curly hair. Don't let the appearance of the thin foam earpads fool you— they are comfy, secured well and transmit the audio clearly. (UPDATE: I had initially tried adding a pair of Yaxi pads as suggested by another helpful reviewer, but those would not stay on, and were so thick the sound was being muffled. Stick with the OEM earpads!) Next up was to find a longer extension cable that fit. Curious that Koss doesn't offer anything—even on their website. I first noted that the tip that plugs into the cable that is permanently attached to the headphones is 2.5mm (male) and the other plug that goes into your computer, music device, etc. is 3.5mm (thicker plug), also male. Then I had to learn the difference between TRRS (3 black rings on the tip of the plug) and TRS (2 black rings). So the search was on for a quality extension cable with a 2.5mm male TRRS plug and a 3.5mm male TRS plug—which is exactly what these headphones require. I found only one such cable on Amazon—ASIN: B08MX53T1T and took a chance despite the ridiculous product name. Turns out it is of solid build and does not diminish the sound quality of these Koss headphones. Total length of combined straight & coiled cord is 51 inches, not stretched. Minimal upgrade costs and these headphones are customized for my comfort & listening pleasure! I recommend all of these parts, but probably not as a mobile on-the-go setup—I'm not sure the headphones would hold up to that, they seem too fragile for traveling with. (The extension cable would certainly hold up, though.) Enjoy, and I hope this helped!

Soy muy aficionado a koss desde hace muchos, años. Mis primeros auriculares fueron Koss. Me gusta su sonido y que son ligeros, aunque son demasiado caros. Bajando el precio venderan mas.
