The open-back design allows air to flow through the earcup, creating a more natural, room-like soundstage. Instruments feel more naturally positioned and the sound is less fatiguing over long sessions. For mixing, the open-back presentation makes it easier to judge stereo width and depth.
The DT 990 Pro 250Ω version requires a headphone amplifier to reach its full potential. Using it from a laptop socket will produce insufficient volume and less dynamic range. A dedicated headphone amp or high-quality interface headphone output is recommended.
The DT 990 Pro has a V-shaped frequency response with enhanced bass and a bright, airy top end. This makes it initially exciting and enjoyable, but the bright treble can be tiring over very long sessions.
Mixing engineers and critical listeners who need a wide, open soundstage. Not suitable for tracking where sound isolation is needed. Requires a headphone amplifier for best results.
The Beyerdynamic DT 990 Pro is an excellent open-back headphone for mixing and critical listening. The wide soundstage and detailed sound make it a pleasure to work on. The 250Ω impedance requires an amplifier, and the open design leaks sound. But for mixing sessions in a quiet studio environment, the DT 990 Pro is a compelling choice at £129.
