Overview

The Audeze MM-520 is an open-back, planar magnetic headphone built as a portable reference tool for mixing and mastering. A 90mm Ultra-Thin Uniforce diaphragm sits inside a Fluxor magnet array with Fazor phase management and SLAM acoustic tuning, giving it tight, well-defined bass and accurate midrange detail. At 18 ohms and 102 dB sensitivity, it's easy to drive from an interface, laptop, or portable source, making it a reliable reference you can bring with you outside the studio.
