Summary: I wrote one year ago that my ur40 headphone wouldn't be suite solid. It was partially an error. Yes finally after one year they have let me down... But 3 hours per day using, and a so good quality for a so good price: I have ever buy 2 new pairs of these headphones!
Summary: I highly recommend the UR40 open back phones for great dynamic listening and every studio should have a pair for rough mixing and comparable listening, because most music is listened to on phones, buds, small laptop speakers and cars.
Pros: Great dynamic sound. Open back design makes it perfect for mixing music with surround ambience very similar to using desk top monitor speakers for mixing, but without bothering others in the house. Comfortable and breathable for long mixing sessions.
Cons: Cord too short, I had to buy a an extended cord. Would be better if the cord came out of one side rather than both sides.
Summary: I've bought these headphones twice, after each pair's 3-year life expectancy expired. However, seeing as they were only $40 (and I've found them even cheaper under the RadioShack brand), they weren't too shabby.
Summary: I've been using my pair of UR40's for over 10 years & they still sound awesome! I've ripped wires out of the phones ( & they were easy to fix!) pulled the cord out of my cdplayer/ipod/pc/etc, dropped, thrown, shook, folded incorrectly, and sat on them- & their still here.
Pros: Great sound, very snug & comfortable fit, large earpads don't crush ears & BEST PART- Outer mesh allows the set to breathe- no swamp ears!
Cons: Short cable, slick black material on earpads eventually wears off
Summary: I wear a sweat band at the gym over the headphones. It improves the fidelity and base, and makes the external noise significantly lower. Toss in large gym bag when done. Incredible durable--averages 5 years of use 7 hours a week before open circuit one channel. Best value on the market by far.
Summary: I am musician, cellist, and it is my first Koss. Sound is clear and crisp, basses also detailed and limited. Stereo restitution is good. Ÿou can ear each instrument with good orchestral record. I try it first with organ music and also vocal music.
Pros: open-closed headphones, very good sound restitution for classical or voices, limited basses
Summary: I bought two pairs of these for 30 a piece new from a store that was closing down. They have worked very well. Truly a "live sound" type of sound. No need for an EQ really. One pair make a slight cracking sound when there is heavy bass, but the other is working well for now.
Summary: I have used mine for 8-10 years and have loved them. I've dropped them, gotten them caught on things and pulled out of the jack, etc. and still haven't had any problems. I use them all day for work and they're extremely comfortable.
