Summary: I have owned these for 10 to 20 years and used the warranty at least once, at which time the drivers were renewed. I felt guilty spending so much on a set of headphones - until I heard them, after which I never regretted the purchase. My speakers include a pair of time-corrected (with digital crossovers) K-horns in a 5.1 system, a pair of Dayton-Wright electrostatics in another 5.1 system, and a pair of Ambience ribbon speakers in a 2.1 system.
Summary: These are some of the best high-end headphones out there. The sound of these phones is full and natural. No heavy bass or bright highs. You can listen all night long. They are very comfortable, and lightweight. Pricey, but there are deals out there. The 950 have a very open sound, which is a bit different from other headphones I have.
Summary: I've had these for 20 years now and love them. If you are into private listening with fullness and detail you should have a set of these. I am looking to buy a 2nd pair for my other stereo. They really stand behind the product. I had a problem once and they replaced them no questions asked.
Summary: May i just add one important factor with these fantastic cans. Please make an attempt to use all battery power when listening despite having the rca cord I was in cloud 9 and did not want to leave sonic heaven Very thirsty for juice but i use rechargable - right to the end of red light- with no noticeble lack of quality
Summary: First of all, these ESP-950's aren't for your average listener. These awesome headphones produce an accurate, detailed & very transparent sound most audiophiles and many amathur audiophiles (I'm in the later group) will enjoy using. Though I'm still more use to a closed-ear style headset, having been weaned on the original Pro4A's, with the liquid filled headphone ear covers back in the late sixties, I found these lightweight headphone cups quite comfortable with their...
Summary: I cannot believe the inane and ludicrous use of this web site. I though it was to be for honest and impartial evaluations of the product under discussion. To those idiots who don't know what a message board or chat rooms are for get a life. Now to my review. In one word STUNNING! These phones have got to be close to being the best phones on the market. Crystal clear highs and subsonic lows.
Summary: these are simply one of the best sounding headphones on the market. however they'd be even better if koss would address some of the problems below: -as most people, i too have had that horrible squealing problem. here's a couple of tricks to (momentarily) stop it: 1) give the outer portion of the ear piece a flick with your finger 2) turn off the headphones for about 8 hrs. then vaccum the outer portion of each ear piece - do not vaccum the inner portion.
Summary: I've had these phones for many years and after putting up with the squeal for a long time I sent them to the repair facility here in Canada. They completely replaced the units and now they have been working for the last 3 months perfectly. I have always loved the sound (or lack of it) ever since I first purchased them. They really don't have any sound but simply give you what's on the recording.
Summary: I am very satisfied with my purchase. Everytime I inform people that I spent over $500 on headphones, they react like I' nuts...until they give these beauties a listen. I have never had a problem in the time I've had them (since 1994). No "squeal," no discharges. It is important to attenuate the volume on the accompanying energizer properly or you will introduce distortion. Adjusted properly, the sound is crisp with airy highs and decent bass. Midrange is incredible.
