Koss ESP-950 Electrostatic Headphone ESP-950 Headphones & Earphones
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.
