When every EQ move, compression adjustment and balance decision matters, accuracy becomes everything. The Audeze MM-520-back headphones were developed to provide recording, mixing and mastering engineers with a trusted reference that reveals the truth in every production. Created in collaboration with 18-time Grammy Award-winning mix engineer Manny Marroquin, the MM-520 builds upon the acclaimed MM-500 platform while introducing Audeze’s latest SLAM technology for enhanced low-frequency precision and spatial realism. Combining reference-grade planar magnetic performance with exceptional comfort and studio-ready efficiency, the MM-520 is designed to help engineers make critical decisions with confidence and achieve mixes that translate consistently across real-world playback systems.

Reference Accuracy Designed for Professional Production

The MM-520 was engineered specifically for critical listening applications where detail, balance and translation are essential. Its open-back architecture creates a spacious and natural soundstage that makes it easier to evaluate stereo imaging, depth and instrument placement with precision. Working closely with Manny Marroquin, Audeze refined the headphone’s voicing to deliver a balanced presentation capable of exposing subtle tonal changes, transient information and mix details that often remain hidden on conventional headphones. The result is a highly revealing monitoring tool equally suited to mixing, mastering, editing and professional content creation.

Advanced Planar Magnetic and SLAM Technology

At the core of the MM-520 is Audeze’s 3.5" planar magnetic driver featuring an Ultra-Thin Uniforce diaphragm, Fluxor magnet array and Fazor waveguide technology. These innovations work together to deliver exceptional clarity, ultralow distortion and lightning-fast transient response across an expansive 5Hz–50kHz frequency range. New SLAM (Symmetric Linear Acoustic Modulator) technology further enhances performance by optimizing internal acoustic pressure, resulting in greater low-frequency authority, improved spatial imaging and increased depth without sacrificing the neutral midrange presentation that professional engineers rely on for accurate monitoring.

Built for Long Sessions and Everyday Studio Use

Designed for demanding studio environments, the MM-520 combines premium performance with exceptional comfort and practicality. Upgraded memory foam ear pads provide long-term listening comfort, while the magnetic attachment system allows for quick removal and replacement when needed. Despite its professional capabilities, the headphone’s efficient 18 Ohm design makes it easy to drive directly from audio interfaces, mixing consoles, laptops and portable production rigs without requiring a dedicated amplifier. Hand-assembled in Southern California and built to withstand daily professional use, the Audeze MM-520 delivers the transparency, reliability and comfort required for today's most critical audio workflows.
