Superlux HD-990 Studio Headphones

Open-Back Studio Monitoring Made Accessible

The Superlux HD-990 32ohms is a fully open-back dynamic headphone built for mixing, arranging, mastering, and long monitoring sessions. Its 50 mm neodymium driver delivers a balanced frequency response from 10 Hz to 30,000 Hz with stable imaging, helping engineers judge dynamics, spatial cues, and timbre with confidence. The 32 Ω impedance and 93 dB/mW sensitivity let it run comfortably from audio interfaces, laptops, and mobile devices without needing a dedicated headphone amplifier.

Comfort and Inclusions

Soft velour earpads, a uniform ~4.5 N clamping force, and a ~245 g weight (without cable) keep extended sessions fatigue-free. A 2 m straight cable with a 3.5 mm plug, a 3.5/6.3 mm gold-plated stereo adapter, and a carrying pouch come in the box.
