A New Generation of Studio Accuracy

The Audeze MM-520 represents the latest advancement in the Manny Marroquin Signature Series, developed in collaboration with the 18-time Grammy Award-winning mixing engineer for exceptional studio translation. Expanding upon the highly regarded MM-500, these open-back headphones incorporate Audeze’s groundbreaking SLAM™ (Symmetric Linear Acoustic Modulator) technology. By refining internal earcup air pressure, SLAM™ delivers extraordinary bass authority and enhanced soundstage openness while maintaining essential midrange accuracy. Furthermore, the MM-520 is engineered to provide dependable monitoring across a wide variety of professional production environments. Its advanced acoustic design helps reveal subtle details that are often overlooked with conventional headphones.

Revolutionary SLAM™ Acoustic Technology

The defining innovation of the MM-520 is the integrated Symmetric Linear Acoustic Modulator (SLAM™) system. This advanced solution fine-tunes internal air pressure within the open-back earcups to maximise driver consistency and efficiency. The outcome is a powerful yet remarkably precise low-frequency response combined with improved spatial transparency, all without compromising the critical midband region. This technology allows engineers to make more confident decisions during mixing and mastering sessions. It also enhances overall realism, creating a more immersive and natural listening experience.

Designed with Manny Marroquin

Created alongside 18-time Grammy-winning mix engineer Manny Marroquin, the MM-520 is purpose-built for demanding professional applications. Carefully tuned for reliable mix translation, it ensures that productions retain their balance across car audio systems, club sound systems, home speakers, and consumer headphones. As a result, engineers can work with greater certainty when evaluating bass response, dynamics, and tonal balance. Its reference-grade presentation makes it an invaluable tool for both recording and post-production work. The MM-520 helps streamline workflows by reducing the need for constant cross-checking on multiple playback systems.

Advanced 90mm Planar Magnetic Driver Technology

At the heart of the MM-520 are large 90mm planar magnetic drivers featuring Ultra-Thin Uniforce™ diaphragms and a Fluxor™ Neodymium N50 magnet structure. These drivers react instantly to intricate musical transients, delivering exceptional speed and precision. Combined with Fazor™ phase management technology, the MM-520 achieves ultra-low distortion levels below 0.1% THD, ensuring highly accurate and transparent sound reproduction. This sophisticated driver architecture preserves the integrity of every recording with remarkable detail. Even complex arrangements remain clear and well-defined, allowing critical listening without compromise.

Flexible Performance for Modern Production

With its low 18-ohm impedance and elevated sensitivity, the MM-520 integrates seamlessly into contemporary production workflows. Whether connected to a professional mixing console, portable recording interface, or directly to a laptop, these headphones provide consistent and authoritative performance without requiring a dedicated headphone amplifier. This versatility makes them equally suitable for studio installations and mobile production environments. Users can enjoy the same level of accuracy regardless of their chosen source equipment. The efficient design also ensures excellent performance when travelling between different work locations.

Enhanced Comfort for Extended Listening

Engineered for prolonged professional use, the MM-520 features upgraded memory foam ear cushions that evenly distribute pressure and minimise listening fatigue. In addition, a newly developed magnetic attachment mechanism enables quick and effortless earpad replacement and maintenance. This practical design improves long-term durability while helping users maintain peak comfort during lengthy recording, mixing, or mastering sessions. The lightweight construction further contributes to all-day wearability. Every element has been designed to support productivity without distraction.

Exceptional Frequency Range and Dynamic Capability

Offering an expansive frequency response from 5Hz to 50kHz, the MM-520 reproduces both deep sub-bass information and delicate high-frequency detail with remarkable accuracy. Capable of handling up to 5W RMS power and delivering clean output levels exceeding 130dB SPL, these headphones provide substantial dynamic headroom with virtually no audible distortion. This outstanding performance ensures they meet the rigorous technical requirements of modern professional audio production. Their wide bandwidth allows engineers to monitor recordings with greater confidence and precision. The result is a highly revealing listening tool capable of exposing every nuance within a mix.
