Koss ESP-950 Electrostatic Stereophone

Koss UR20 Stereophone, Dynamic Element for extended frequency response Closed leatherette ear cushion for maximum isolation and deep bass. Built for maximum durability for DJ and recording use Straight, single entry 8 foot cord - Black - Mini-phone stereo 3.5 mm connector The ESP950 Electrostatic Stereophone System is the pinnacle of audio reproduction. The standard upon which all other electrostatic headphones can be measured. A professional listening system so distortion free, it literally pushes the limits of the world's most sophisticated instruments that attempt to measure its performance. The result is an experience that no other stereo system can approach. A revolutionary design in electrostatic transducers which includes cross matched mechanical damping and semi-conductive coating. The result is an ultra-flat frequency response across the entire range: deep, clean bass with real power that other attempts at electrostatic transducers can only envy. You would expect nothing less from the people who introduced the world to private listening with its first SP3 stereophone in 1958. The ESP includes the Electrostatic Stereophone, energizer, battery pack, leather carrying case, connecting cables, and 120 VAC adapter. This unit is equipped with soft, vinyl closed ear cushion design for isolation. The Electrostatic Stereophone features pivoting ear cups and adjustable, detachable headband for comfort and convenience. The ESP950 has a straight, dual entry 4 foot cord/6 f

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.
