The Audeze MM-520 is a professional open-back planar magnetic reference headphone developed in collaboration with 18-time Grammy-winning producer and engineer Manny Marroquin. Expanding Audeze's professional MM series, the MM-520 combines large 90mm planar magnetic transducers with Audeze's proprietary Symmetric Linear Acoustic Modulator (SLAM) technology to optimize airflow and internal pressure for accurate low-end translation, spatial precision, and clinical clarity.
Handcrafted in the USA, the MM-520 is engineered specifically for producers, recording engineers, and content creators who require mastering-grade monitoring reliability both inside and outside the studio. Featuring a low impedance of 18 ohms and a sensitivity rating of 102 dB/1mW, these headphones can be easily driven directly by studio consoles, audio interfaces, or laptops. Upgraded magnetic memory foam earpads ensure long-session comfort and effortless maintenance during demanding mix sessions.
KEY FEATURES & PROPRIETARY TECHNOLOGIES
- Symmetric Linear Acoustic Modulator (SLAM): Optimizes internal air pressure and airflow distribution across the open-back earcups, enhancing low-frequency impact and spatial imaging without obscuring midrange detail.
- Manny Marroquin Voicing & Tuning: Meticulously tuned alongside the 18-time Grammy-winning engineer to ensure reliable mix translation across car stereos, club PAs, and consumer audio devices.
- 90mm Planar Magnetic Transducers: Utilizes Ultra-Thin Uniforce diaphragms, Neodymium N50 Fluxor magnet arrays, and Fazor phase management for transient response and ultra-low distortion (<0.1% THD).
- High Sensitivity & Low Impedance: 18-ohm impedance and 102 dB/1mW sensitivity allow for high-performance operation directly from laptops, portable audio interfaces, or mixing consoles without requiring high-power external amplification.
- Magnetic Memory Foam Earpads: Plush, fatigue-reducing memory foam ear cushions feature a magnetic attachment system for quick removal, cleaning, and replacement.
- Ultra-Wide Frequency Extension: Wide 5 Hz to 50 kHz frequency bandwidth captures subsonic frequencies and high-frequency harmonics.
