What reviewers say

Reviewers agree the DT 990 Pro is comfortable and solidly built, with spacious, detailed sound that MusicRadar thinks suits mixing, and SoundGuys calls it a bargain. MusicRadar and SoundGuys note the 250-ohm version needs an amplifier; Audio Science Review measured exaggerated treble, weak deep bass and high distortion, and doesn't recommend it.
