Koss KPH40 Utility On-Ear Headphones, Detachable Interchangeable Cord System, Retro Style, Ultra Lightweight Design (Stealth Black)

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!

These are Gods headphones. You won't find more amazing sound for the money than with any of the KOSS titanium driver headphones like these! Had these for a year now. They have the same exact drivers as the KTXPro1 and other Koss titanium headphones but the durable and lightweight metal headband is stronger and comfy. Feels almost like your not even wearing headphones. Because the speaker pivots in the center they perfectly angle themselves to fit your ears unlike the KTXPro1 or PortaPro. The cord can be swapped and upgraded to a USB-C version with a built in high res DAC that really improves the already amazing sound when connected to your smartphone or PC. They also now make a bluetooth upgrade module for these! The original cord was damaged when I got it caught on a door knob one day and kept walking. KOSS shipped me a new one within 5 days no questions asked. The USB-C utility cable got snagged at the gym after having it almost a year and again to my surprise KOSS replaced this much more expensive upgrade cable no questions asked and mailed it to me in just a few days. Koss provides their famous Lifetime warranty on these and will replace them with no hassle. I have used the warranty in the past on a pair of KTXPro1 headphones that were 7 years old and they actually honored the warranty. There are also awesome customization accessories available for these online. Besides the USC-C and Bluetooth upgrades I mentioned Koss also sells many different color earpads. Aftermarket companies make speaker housing replacements in many colors, speaker mod and cable upgrade kits from Hundo and even replacement metal headbands on some sites are available in both black and stainless steel. There is even a Koss modding community on Reddit.

The Koss KPH40 headphones are really good for what they are — a lightweight, budget headphone. If you ended up here after watching a glowing review by a tech influencer stating that these compete with $200 cans, you will probably be disappointed. They just don't, especially if you appreciate strong bass. Detail in the mids and highs are outstanding; no notes. Crisp, sparkly, but not fatiguing. The low end lacks any 'oomph.' I suppose that is mostly to do with how open they are. There is none of the sound pressure you feel from over-the-ear sets. If you try to force them with EQ, you get a ton of distortion. Their comfort is amazing. That is what you get in the trade for the bass, and I think the compromise is a fair one in the right usage case. I forget that I'm wearing these. They're a dream. Getting them adjusted properly is a bit fidgety, but it can be done. They're so light, the clamp force is just right, and the ear pads are soft & breathable. No noise cancellation to speak of; you will be very aware of your surroundings. Whether that is a positive or negative is up to you. Avoid using at high volumes in quiet public places, sound bleeding is significant; don't be *that* person. These are great for casual listening. Teleconferencing. I think they would be amazing for gaming. I have headphones that sound better for not a lot more money, but they're big, hot, and uncomfortable. I reach for the Koss KPH40 far more often. They are not "the best headphones under $200!!!!," but they may be the best for you during most points of the day.

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

So good are these, and for travelling they are just perfect

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.

Doskonałe słuchawki dla ludzi, którzy słuchawek a uszach specjalnie nie lubią.Nie przeszkadzają, nie uwierają, a grają doskonale. Lepsze od Porta Pro. I ładniejsze. Jedne z najlepszych słuchawek jakich słuchałem i w stosunku do tej jakości rewelacyjnie tanie. Choć widzę, że już powoli drożeją, a dodatkowe wymienne kable (np. usb-c) są koszmarnie drogie.
