The MM-100 is Audeze’s entry into the professional mixing headphone space at a more accessible tier, while retaining much of the core driver architecture and design lineage of the MM-500. It uses 90 mm planar magnetic drivers with ultra-thin Uniforce diaphragms and Fluxor magnets, delivering precise transient response and consistency across the frequency spectrum.

The open-back design is engineered for studio use, with a focus on accurate phase behavior and mix translation. The MM-100 offers notably low distortion and a linear response, particularly in the low mids and upper bass—areas often misrepresented in dynamic headphones. While the treble range is tuned conservatively, it maintains clarity for balancing high-frequency content without excessive sharpness.

The mechanical design borrows structural elements from Audeze’s higher-end models, with adjustable spring steel headband and floating suspension strap. The earpads are slightly smaller than the MM-500 but use the same angled geometry for accurate imaging. It includes a single-sided detachable cable and ships with a soft protective pouch.
