Lose yourself in the music you love, enjoying enhanced sound quality and hours of listening comfort. The MDR-Z7M2 provides elegant audio reproduction, from highs to lows, with 70mm HD drivers, aluminium-coated Liquid Crystal Polymer diaphragms, Fibonacci-patterned grill and a larger magnet that's twice the volume of the magnet used in its predecessor. The result is the reproduction of a three dimensional, spatial sound experience existing in live atmosphere.
