The MM-520 is the next evolution of its purpose built studio headphones in the Manny Marroquin Signature Series
Building upon the award-winning foundation of the MM-500, the new MM-520 integrates Audeze’s revolutionary SLAM™ (Symmetric Linear Acoustic Modulator) technology to provide audio professionals and creators with unprecedented bass accuracy and spatial detail.
Developed in close collaboration with 18-time Grammy-winning mix engineer Manny Marroquin, the MM-520 is a purpose-built tool designed to deliver mixes that translate perfectly across any system. By incorporating SLAM™ technology, the MM-520 optimizes air pressure within the earcup to enhance low-frequency impact and soundstage transparency without sacrificing the mid-range neutrality that made the original MM-500 a studio staple.

Audeze MM-520 Key Features:
- Audeze’s Symmetric Linear Acoustic Modulator (SLAM™) enhances bass performance and spatial imaging, providing a more visceral yet accurate low-end response.
- Refined by one of the industry’s top engineers to ensure mastering-grade reliability and emotional engagement.
- Features 90mm planar magnetic drivers with Ultra-Thin Uniforce™ diaphragms and Fazor™ phase management for ultra-low distortion and clinical precision.
- High sensitivity and low impedance allow the MM-520 to be driven easily by consoles, interfaces, or laptops, both inside and outside the studio.
- Upgraded memory foam earpads designed for comfort during marathon mixing sessions, with magnetic attachment for easy replacement
“The MM-520 represents the latest entry in our mission to provide creators and professionals with the ultimate monitoring tool” stated Sankar Thiagasamudram, Audeze CEO. “By adding SLAM™ technology to Manny’s signature series, we’ve created a headphone that delivers even more truth in the low-end while maintaining the signature clarity Audeze is known for”, he added.”
The Audeze MM-520 is available for $1799 atwww.audeze.com and through authorized dealers worldwide.

What is SLAM technology?
SLAM, maintains a perfect seal and diaphragm tension, while simultaneously improving bass performance.SLAM incorporates precisely engineered channels seamlessly integrated into the ring that connects the earpads to the drivers. Each channel’s length, cross-section, and shape are meticulously tuned through advanced simulations, precision measurements, and critical listening to achieve the ideal low-frequency response.
These acoustic channels relieve pressure buildup and acoustically modulate the low-frequency response, smoothly boosting bass, similar to adding a gentle low-frequency shelf. The result is significant bass enhancement, 6 dB or more extending as deep as 10 Hz.
A proper seal between earcups and ears inherently creates increased pressure between the ear and diaphragm. Consequently, the diaphragm faces greater resistance when compressing air toward the ear compared to when moving away.
SLAM resolves this issue by allowing controlled pressure equalization between the diaphragm and ear area, ensuring fully symmetric and uniform forces regardless of diaphragm direction. This linearized force significantly reduces distortion and improves transparency, adding openness and clarity to the soundstage.
