Audeze MM-520 Open-Back Professional Headphones

The Audeze MM-520 is an open-back planar magnetic headphone built specifically for studio mixing and recording, refined in Audeze’s Southern California workshop with the latest generation of acoustic technologies. At its core are 90mm planar magnetic drivers featuring SLAM technology for tighter, deeper low-end definition and precise midrange expression — the kind of accuracy professional engineers need when decisions have to translate out of the headphone and into the room. Audeze’s Fluxor magnet array, Fazor phase management, and Ultra-Thin Uniforce diaphragm work together to deliver a frequency response spanning 5Hz to 50kHz with less than 0.1% THD at 100dB SPL. Upgraded memory foam earpads with magnetic attachment make the MM-520 as practical as it is precise, purpose-built for marathon sessions in the studio or out in the field.

“The MM-520 is more focused overall. Everything translates a little easier — just more dialed in.” — Manny Marroquin, 18-Time Grammy-Winning Producer/Engineer

Key Features

• SLAM Technology: Proprietary acoustic management system engineered for low-end definition and midrange precision in planar magnetic drivers
