Sony MDR-CD780

High Quality Closed-Front Open-Back Headphones create a wide and open sound stage and are ideal for use with all digital sound sources, from Sony Walkman® personal stereo players to Hi-Fi stereo components
Aura-Nomic design and virtual shaft mechanism in the headphone housing positions the earpads in accord with angle of the head, for a stable and comfortable fit
Large 50mm Drivers for Deep Bass, Wide Dynamic Range are significantly larger than most headphones for noticeably deeper bass, lower distortion and wider dynamic range; frequency response extends down to a low 5Hz
Anti-Resistant ABS Resin Baffle Board minimizes resonance to produce purer sound
25mm Thick Urethane Earpads distribute pressure evenly around the ear for exceptional comfort over extended listening sessions
Extremely Wide Frequency Response 5Hz-30kHz spans frequencies above and below the entire audible sound spectrum
Self-Adjusting Double-Band Headband for a customized fit and increased comfort
Higher Power Neodymium Magnet for maximum energy with minimum size; ounce for ounce, Neodymium is far more powerful than conventional Samarium Cobalt or Aluminum magnets
Replaceable Cloth Earpads are removable and washable
