Audeze MM-520 Open-Back Professional Planar Magnetic Headphones

MM-520 Open-Back, Over-Ear Professional Planar Magnetic Headphones, by Audeze.

The Audeze MM-520 is the next evolution in the Manny Marroquin Signature Series, engineered alongside the 18-time Grammy-winning mix engineer for flawless studio translation. Building on the acclaimed MM-500, this open-back headphone introduces Audeze’s revolutionary SLAM™ (Symmetric Linear Acoustic Modulator) technology. By optimizing internal earcup air pressure, SLAM™ delivers unprecedented low-end impact and soundstage transparency while preserving critical midrange neutrality.

At its core, the MM-520 utilizes 90mm planar magnetic drivers featuring Ultra-Thin Uniforce™ diaphragms and Fazor™ phase management. This advanced architecture ensures mastering-grade precision, pinpoint spatial imaging, and ultra-low distortion (under 0.1% THD) across an expansive 5Hz to 50kHz range. The result is a clinical monitoring tool that eliminates low-end guesswork in any environment.

Tailored for both traditional consoles and mobile workflows, its high-sensitivity, 18-ohm design is easily driven by laptops and portable interfaces alike. For marathon sessions, it features upgraded memory foam earpads for premium comfort, complete with a new magnetic attachment system for effortless replacement.
