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.\u003c\/p\u003e\n\n\u003cp\u003eHandcrafted 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.\u003c\/p\u003e\n\n\u003ch3\u003eKEY FEATURES \u0026amp; PROPRIETARY TECHNOLOGIES\u003c\/h3\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eSymmetric Linear Acoustic Modulator (SLAM):\u003c\/strong\u003e Optimizes internal air pressure and airflow distribution across the open-back earcups, enhancing low-frequency impact and spatial imaging without obscuring midrange detail.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eManny Marroquin Voicing \u0026amp;
