Beyerdynamic DT 990 Pro X - Open-back clarity for the mix

The DT 990 Pro X is an open-back studio headphone for producers and engineers who mix, edit and listen critically. Its new STELLAR.45 drivers run at 48 ohms, so they reach full level straight from an interface or laptop - no dedicated amp needed, unlike the classic 250-ohm DT 990 Pro. A detachable locking cable replaces the old fixed lead. Available at Soundium.

Key Features

• STELLAR.45 drivers: New 48-ohm driver system delivers a detailed, open sound from almost any source.
• Easy to drive: Low 48-ohm impedance runs cleanly from interfaces and laptops, no headphone amp required.
• Open-back design: Wide, natural soundstage that keeps your ears fresh through long sessions.
• Detachable locking cable: Mini-XLR connector swaps the cable in seconds, unlike the older fixed lead.
• Velour earpads: Soft, breathable cushions stay comfortable over multi-hour mixes.
• Made in Germany: Handcrafted build with replaceable parts for years of service.

Customer Benefits

The open-back stage gives an airy, honest read on your low end and reverb tails, which is exactly what you want when editing and mixing. Dropping from 250 to 48 ohms means the DT 990 Pro X reaches proper level from a laptop or small interface without a separate amp, so it slots into a mobile setup the day it arrives. Light velour pads and a 292 g body keep it comfortable across a full session.
