The Samson SR990 is a wired, over-ear closed-back studio reference headphone designed for accurate mixing, critical listening and music playback. It uses 50 mm neodymium drivers with 32 Ω impedance and 95 dB sensitivity, delivering a 20 Hz-20 kHz response. A 8.25 ft (2.5 m) cable terminates in a gold-plated 3.5 mm connector with a gold-plated 6.3 mm adapter. Premium velour and protein-leather ear pads and a self-adjusting headband provide long-term comfort and passive isolation.
