Audeze MM-520

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.

The SLAM™ Technology Advantage
The defining breakthrough of the MM-520 is the integrated Symmetric Linear Acoustic Modulator (SLAM™). This system optimizes internal air pressure within the open-back earcups to maximize driver linearity. The result is a visceral yet highly accurate low-frequency impact and enhanced soundstage transparency, all without muddying the critical mid-range.

Engineered Alongside Manny Marroquin
Developed in partnership with 18-time Grammy-winning mix engineer Manny Marroquin, the MM-520 is built for demanding studio environments. Meticulously voiced for flawless mix translation, it ensures your work sounds consistent on car stereos, club PAs, and consumer headphones alike—eliminating low-end guesswork so you can deliver final bounces with absolute confidence.

Massive 90mm Planar Magnetic Drivers
At the core of its clinical performance are large 90mm planar magnetic drivers utilizing Ultra-Thin Uniforce™ diaphragms and a Fluxor™ Neodymium N50 magnet array. These drivers respond instantaneously to complex transients. Paired with Fazor™ phase management, the MM-520 achieves an ultra-low distortion rating (<0.1% THD), ensuring uncoloured, precise sound reproduction.

Versatile Driveability for Modern Workflows
With a low impedance of 18 ohms and high sensitivity, the MM-520 fluidly adapts to any modern workflow. Whether you are plugged into a high-end studio console, a portable audio interface, or directly into a laptop while on the move, these headphones deliver consistent, full-scale performance without the need for a dedicated amplifier.

Premium Comfort for Marathon Sessions
Built to fade into the background during grueling sessions, the MM-520 features upgraded memory foam earpads that distribute weight evenly and minimize fatigue. Additionally, a new magnetic attachment system allows for effortless earpad replacement and cleaning, extending the longevity of your headset through years of daily commercial use.

Unrivaled Frequency Extension and Dynamics
Boasting an ultra-wide frequency response from 5Hz to 50kHz, the MM-520 captures subsonic depth and high-end detail that standard monitors miss. Capable of handling up to 5W RMS and pushing clean levels past 130dB SPL, it provides a massive, distortion-free dynamic range that easily satisfies the strict technical demands of modern production.
