It succeeds the MM-500 and introduces SLAM – Symmetric Linear Acoustic Modulator – an acoustic system that manages air pressure inside the earcup to address the most persistent weakness of open-back designs: low-end control and sub weight. The 90mm driver platform carries over from the MM-500 with Ultra-Thin Uniforce diaphragm, N50 Fluxor magnet array, and Fazor phase management intact. SLAM is an additional acoustic layer on a proven transducer, not a ground-up redesign. At 18 ohms impedance and 102 dB\/mW sensitivity, the MM-520 runs directly from an audio interface, console headphone output, or laptop without a dedicated amplifier.\u003c\/p\u003e\n\n\u003ch3\u003eTranslation as the design standard\u003c\/h3\u003e\n\u003cp\u003eStudio headphones are judged on one thing: whether the mix holds up everywhere else. The MM-520 was built around that question. Midrange neutrality is the foundation – kick and bass need to lock without bloating, vocals need to sit correctly, reverb and delay tails need to be readable and placeable. SLAM adds deeper and firmer low-end extension that typically falls short in open-back designs, where pressure equalization bleeds bass energy. The result is a reference tool where decisions made during mixing carry across playback systems more consistently – fewer corrections needed when moving from headphones to monitors, consumer earbuds, or a car stereo.\u003c\/p\u003e\n\n\u003ch3\u003eHardware built for long sessions\u003c\/h3\u003e\n\u003cp\u003eMemory foam earpads attach magnetically, making replacement or cleaning a tool-free process. At 555 g the MM-520 sits at the heavier end of the planar magnetic monitoring category – relevant for sessions running multiple hours. The package includes a 2.5 m cable, 3.5 mm to 6.3 mm adapter, travel case, and soft carry bag. THD below 0.1% at 100 dB SPL and a frequency response extending to 5 Hz and 50 kHz place the MM-520 in measurement-grade reference territory. Maximum SPL above 130 dB provides headroom for tracking loud sources without driver limiting. Priced at $1,699, it occupies the top position in Audeze's Marroquin lineup, above the MM-500 and the more accessible MM-100.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSLAM technology – symmetric air pressure management for controlled bass in an open-back design\u003c\/li\u003e\n\u003cli\u003e90mm planar magnetic driver with Ultra-Thin Uniforce diaphragm and N50 Fluxor magnets\u003c\/li\u003e\n\u003cli\u003eFazor phase management reducing phase distortion and diffraction\u003c\/li\u003e\n\u003cli\u003e18 ohm impedance – runs from interfaces, consoles, and laptops without a dedicated amp\u003c\/li\u003e\n\u003cli\u003e102 dB\/mW sensitivity – usable monitoring levels from standard headphone outputs\u003c\/li\u003e\n\u003cli\u003eTHD below 0.1% at 100 dB SPL\u003c\/li\u003e\n\u003cli\u003eMagnetically attached memory foam earpads – tool-free swap\u003c\/li\u003e\n\u003cli\u003eOpen-back design – natural soundstage, no in-head localization\u003c\/li\u003e\n\u003cli\u003eCo-developed with Manny Marroquin over four years of active studio use\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: open-back, over-ear, planar magnetic\u003c\/li\u003e\n\u003cli\u003eDriver: 90 mm, Ultra-Thin Uniforce\u003c\/li\u003e\n\u003cli\u003eMagnets: N50 Fluxor, dual-sided array\u003c\/li\u003e\n\u003cli\u003eFrequency response: 5 Hz – 50 kHz\u003c\/li\u003e\n\u003cli\u003eTHD: below 0.1% (100 dB SPL, 1 kHz)\u003c\/li\u003e\n\u003cli\u003eImpedance: 18 ohms\u003c\/li\u003e\n\u003cli\u003eSensitivity: 102 dB\/mW\u003c\/li\u003e\n\u003cli\u003eMaximum SPL: above 130 dB\u003c\/li\u003e\n\u003cli\u003eMaximum input power: 5 W\u003c\/li\u003e\n\u003cli\u003eWeight: 555 g\u003c\/li\u003e\n\u003cli\u003eCable: 2.5 m, 3.5 mm to 6.3 mm adapter included\u003c\/li\u003e\n\u003cli\u003ePrice: $1,699\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Audeze","offers":[{"title":"Default Title","offer_id":54012413477201,"sku":"60262","price":2191.31,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/AudezeMM-5201.jpg?v=1781175868","url":"https:\/\/wrdtunes.com\/fr\/products\/audeze-mm-520","provider":"Wired Tunes","version":"1.0","type":"link"}
