Audeze MM-520 Open-Back Professional Headphones

Precision You Can Trust: The New Standard for Mix Translation

The Audeze MM-520 is a purpose-built open-back planar headphone designed for engineers who need their mixes to translate flawlessly across every playback system. Voiced in close collaboration with 18-time Grammy-winning mix engineer Manny Marroquin, it delivers a studio-grade monitoring environment that eliminates acoustic guesswork. Whether you are a mixing professional in a world-class facility or a producer working on a mobile laptop setup, the MM-520 is your ultimate tool for critical listening and mastering.

Truth in the Low-End
The defining technical advancement of the MM-520 is Audeze’s SLAM™ (Symmetric Linear Acoustic Modulator) technology. This innovation manages internal air pressure within the earcup through a precision-engineered ventilation ring to optimize airflow and generate a distinct bass port effect. For professionals, this means a level of low-frequency accuracy and "truth" that traditional open-back designs often struggle to provide, ensuring your kick and bass decisions hold up from the studio to the car.

Clinical Precision with Virtually Zero Distortion
Built around 90mm planar magnetic drivers, the MM-520 utilizes Ultra-Thin Uniforce™ diaphragms and Fazor™ phase management to deliver ultra-low distortion and pinpoint transient response. These technologies ensure your audio remains transparent and clinically precise, allowing you to hear deep into every detail of your mix. Because these headphones are remarkably easy to drive with a low 18-ohm impedance, you can expect this mastering-grade performance directly from your interface, console, or laptop.

Unmatched Workflow and Maintenance
Designed for the rigours of daily studio life, the MM-520 features upgraded memory foam earpads that provide luxurious comfort for marathon sessions. A new magnetic attachment system allows worn or degraded earpads to be swapped out in seconds, ensuring your investment stays in peak condition without requiring a service trip. The robust aluminum and steel construction ensures these headphones remain a reliable partner for recording on-the-fly or critical reference monitoring.
