5 Stars, graded on a curve
I bought these looking to replace some Klipsch headphones I’ve had for about 15 years where the foam is starting to disintegrate. I also have a pair of Audio-Technical headphones. I used the Klipsch phones for going to the gym or the times I’m allowed to use at work. They have a slightly better sound quality than these Koss phones but were about three times the price (15 years ago). The AT phones have a superior quality to either the Koss or Klipsch and I use those exclusively for music editing. They were also at a higher price point. There’s probably someone out there with a $500 set of phones who think the ATs are not the greatest, but most of us probably don’t require that level. These Koss phones are doing what I need at a very modest price. They are comfortable and lightweight as can be, and don’t fall off even when I’m running or otherwise moving quickly. I don’t believe they are labeled as noise-cancelling, but my gym plays horrible music over the speaker system and I don’t hear it while I’m listening at a modest level on these Koss phones. My personal preference would like it if these had a better high range, but the bass is perfect without getting muddy. One other feature I like is the cord length. The wires coming off the earpieces end at about one foot length with a female mini-plug end. The supplied extension is just short of three feet, making the total length around four feet with a tangle-free cord. I find this ideal, but for those needing more length, a different extension is an easy fix.

Great Koss sound! Found the perfect cable extension.
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!

Crazy Soundstage
When I first got these I got them out of the box and started listening to music, and music for these is pretty good for the price range. Not much sub-bass to speak of, but it’s a small driver open back unit. The bass that is there is pretty strong. There’s a little bit of bloat in the upper bass range that can be distracting for me right at first, but I find that as I listen longer my ears/brain adjust and it’s not too much of a problem. Kick drums and floor toms have a lot of impact, but I don’t hear much resonance in them like you might through better headphones. Mids and highs are smooth enough that I don’t notice any distracting peaks in tone.Resolution gets better than what these offer, but again, they are 40 dollars. All in all, not a bad sounding unit at all and they are definitely good enough to just relax on the couch, drink a drink, turn your brain off and enjoy music. They are also great if you need to wear something while you are working, doing chores, running errands, or whatever because they aren’t so detailed you start to get overly analytical with the music and get distracted. They are also crazy open in terms of sound isolation, so you won’t miss out on anything happening in the real world. Sound leak is real though, so I would avoid wearing them anywhere where you might be bothering someone else if they could hear them (libraries, planes, etc.).The soundstage on these, though? *chef’s kiss* I was listening to a song where the volume starts low and slowly increases over the first part of the track and I took them off for a second because I thought I had forgotten to switch my source from my living-room speakers to the headphones. It didn’t sound like the music was being pumped straight into my ears, it sounded like the music was in the room with me. At full volume, this effect is less noticeable, but the soundstage and imaging are pretty great for headphones at this price range. I’m always hearing sounds that have me looking around the room. You really feel surrounded by what you are listening to.I don’t know how many people are going to use these for watching movies, but they are crazy good. I like to use headphones to watch movies at night so I can turn them up loud without disturbing my duplex neighbor. I just watched Resident Evil: Welcome to Raccoon City with these (first movie I’ve used them with), while running the headphones off of a Fiio BTR5 (bluetooth adapter) connected to my media computer. I took the headphones off probably 4 or 5 times during the movie thinking that I heard something in the room with me, or something happening outside my house. Little faint noises don’t just sound quiet, they sound like they are actually around you spatially. The effect is honestly pretty striking.I have other gear that technically sounds better if I really want to get analytical with my listening session, but these really do deliver at this price point. If you’re an audiophile you probably have gear better than this, but I would still recommend them just for the reminder that you don’t have to spend a fortune to enjoy what you are listening to. For anyone else, or anyone new to the hobby, this is an awesome place to start. For 40 bucks, how can you lose?

I had insanely high expectations for these and they surpassed them 10 fold. At such a low cost you literally have nothing to lose
Reviewer –
I was dubious about paying £40 for a cheap looking pair of headphones, but they’re the best headphones I’ve tried to date, even compared to much more expensive ones from big brands. I have the Koss KSC75 and while the sound was good the comfort wasn’t there.These are light, comfortable and have the perfect amount of pressure against the ear for me. They also don’t trap heat and get sweaty like over ear headphones do.I’m not the best at describing sound but they’re punchy and have surprisingly good bass.

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.
