Superlux HD990 32Ω Open-Back Studio Headphones with 50mm Neodymium Drivers

The Superlux HD990 32Ω combines a fully open acoustic design with the flexibility to work across a wider range of audio devices. Its slim open-back housing allows unrestricted airflow around the 50mm neodymium drivers, helping reduce internal reflections and creating natural depth, clear stereo positioning and an open sense of space. An optimized magnetic system keeps the drivers responsive, with defined bass, fast transients and detailed dynamics across a wide 10Hz–30kHz frequency range. The 32Ω version is designed for greater source flexibility. It can reach practical listening levels more easily from audio interfaces, computers and many portable devices, making it a strong choice for users who move between studio production and everyday listening systems. Soft velour ear pads and a lightweight 245g construction provide comfort for extended sessions. A detachable 2 m 3.5mm-to-3.5mm cable features a locking connection at the headphone side for a more secure fit. A gold-plated 6.3mm stereo adapter and carrying pouch are also included. As a fully open-back headphone, the HD990 allows outside sound in and lets some audio escape, making it best suited to studios, editing rooms and quiet listening environments.

FULLY OPEN ACOUSTIC DESIGN – A slim, fully open rear housing allows unrestricted airflow around the 50mm drivers, reducing internal reflections for natural depth, spacious imaging and clear stereo positioning.
ENHANCED MAGNETIC DRIVE – Large 50mm neodymium drivers use an optimized magnetic system for responsive diaphragm control, delivering defined bass, fast transients and dynamic detail.
NATURAL, ACCURATE MONITORING – A wide 10Hz–30kHz response delivers controlled lows, clear mids and smooth highs, helping reveal tonal balance, ambience and subtle details in music and mixes.
FLEXIBLE 32Ω PERFORMANCE – The 32-ohm design is easier to drive from lower-voltage sources, making the HD990 well suited to audio interfaces, computers and many portable audio devices without limiting it to a dedicated studio headphone amp.
LIGHTWEIGHT WITH SECURE DETACHABLE CABLE – Soft velour ear pads and a lightweight 245g design support long sessions. The detachable 2 m 3.5mm-to-3.5mm cable locks securely at the headphone connection to help prevent accidental disconnection.
