Sony MDR-CD580

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
40mm drivers are larger than most headphones for deeper bass, lower distortion and wider dynamic range; frequency response extends down to a low 10Hz
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
Wide Frequency Response 10Hz-25kHz spans frequencies above 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
Anti-Resistant ABS Resin Baffle Board minimizes resonance to produce purer sound
Gold plated UniMatch® plug adaptor supplied allows headphones to be used with all types of components
Replaceable Cloth Earpads are removable and washable
Detachable LC-OFC Litz Wire for headphone cable minimizes signal transmission loss and may be removed for storage convenience, or if you would like to purchase a longer cord
