The Sony MDR-7520 is a pair of studio-grade headphones designed for use in demanding professional applications such as mixing and broadcast monitoring. The headphones feature 50mm drivers with Liquid Crystal Polymer diaphragms and neodymium magnets to deliver a frequency response of 5 Hz to 80 kHz, an extended frequency response that brings out the deepest bass and crisp treble.

The headphones have a closed-back earcup design with thick around-ear cushions to block out environmental noise and provide lasting comfort. These headphones are constructed out of a magnesium alloy housing that prevents extraneous vibrations, freeing the lows and highs from outside interference.

The single-sided OFC cable is designed for high conductivity, providing clear signal transfer and up to 3" of slack. The cable is detachable for easy replacement.

A gold-plated 3.5mm plug and a 1/4" adapter offer wide compatibility with a variety of consumer and professional audio devices. A soft case is included for convenient storage and transportation.
