Description

The MDR-7520 earns its spot on the mix-engineer’s desk through sheer detail retrieval. Sony fitted each earcup with a 50mm driver using a liquid crystal polymer diaphragm, a material chosen specifically for how precisely it moves in response to signal — the result is sound reproduction that stays honest across a wide frequency range, so you’re judging the actual mix, not a colored version of it.

50mm driver units with LCP diaphragms for accurate, wide-range reproduction
Closed-ear design for real acoustic isolation in loud or shared spaces
Neodymium magnets paired with OFC voice coils, rated for 4,000mW power handling
Gold-plated stereo Unimatch plug works with both 1/4″ and 1/8″ jacks
OFC cord for clean signal transfer with minimal loss
Soft carrying case included for storage between sessions

Build quality follows a fixed, rugged construction meant to hold up to daily studio or field use rather than fold-flat portability. The earpads use a pliable cushion material that settles naturally around the ear, which does double duty: comfort over long tracking sessions and better passive noise isolation from room bleed.

Specs at a glance: dynamic closed-back design, 50.0mm drivers, 5-80kHz frequency response, 24 ohm impedance, 108 dB/mW sensitivity, 4,000mW power handling, a 9.8 ft cord, and a weight of 9.5 oz.

Whether you’re at a monitoring station in a broadcast booth or tracking vocals in a control room, the MDR-7520 is built to give you a trustworthy, isolated listen every time.
