Product Description

Amazon.com Product Description

Audiophiles seeking the best headphones money can buy should definitely consider the Koss ESP-950 electrostatic stereophone. The headset uses state-of-the-art electrostatic transducers rather than the fiber cone drivers typically used in headphones and loudspeakers. These transducers operate on currentless electrostatic charges with push-pull capacitor plates to induce movement in an intervening, low-mass, semiconductive diaphragm. That's a technical way of saying that these ear pieces are highly sensitive and very responsive to minute fluctuations in audio, rendering your music with delicacy and warmth, and with microdynamics--tiny fluctuations in the musicians' output level--intact. The stereophone uses a soft, vinyl closed-ear design for sonic isolation and includes a battery pack, a leather carrying case, connecting cables, and a 120-volt AC adapter.

I bought this from Amazon in November and it went kaput in December. I since sent it back to Koss taking them up on their lifetime warrenty. I recieved a free new energizer unit. This headphone is excellent (and I own many of the top brands); Use it with a tube headphone amplifier to get best results.

5.0 out of 5 stars An audio classic that still sounds great, June 7, 2011

The Koss ESP-950 has been around for over 20 years, and yet it holds up when compared to the best headphones available today. This is an electrostatic design, known for it's clear and lifelike presentation. Stax, from Japan, is the leader in electrostatic headphones, but the American-made Koss compares well with the Stax Lambda line, comes with a lifetime warranty, and includes a portable amp and a calfskin carrying case for less than the cost of the Stax Lambda models. The overall presentation of ESP-950 is accurate, musical and detailed, with details apparent even at lower listening levels. The bass is slightly rolled-off, but the sound of a string bass (an instrument I used to play) is very accurate. The best sound qualities of this headphone, though, are shown in it's very sweet midrange -- this is a great headphone for vocals. I've owned the Sennheiser HD600 (a well-regarded high-end headphone), as well as the Stax Lambda Pro and I prefer the sound of the Koss ESP-950. Highly recommended!

5.0 out of 5 stars Extremely Pleasing Transcients, February 26, 2003

I bought a pair of the ESP 950's in 1994 from a wholesaler for 495.00, I have collected high end audio gear my whole life and have several complete systems; however night time listening can
make your family very hostile...so I use these for stealth listening of my SACD and Hybrid Surrond encoded DVD's and Cd's.
The transcients on electrostatic phones are amazing, they tend to be a little bright with standard supplied connects, so I use my Transparent Audio Music Plus RCA inter-connects to the koss
E 90 unit which come with and runs these babies. Shear heaven!
I have been thinking of having some one build me a tube headphone amp for these headphones...then my family would be hostile again ..cause I would not want to go to work anymore.
