The H850 is an open-back monitoring headphone built for music production and critical listening. A 50 mm dynamic driver works into an open rear chamber, producing a wide soundstage and natural high-frequency extension. It carries Hi-Res Audio certification from the Japan Audio Society. A detachable 3.5 mm single-ended cable and a 4.4 mm balanced cable are both included, using 2.5 mm dual-pin connectors so customers can match their own source gear. The earpads attach magnetically for fast replacement, which suits studios where the headphones are in constant use.
