What reviewers say

Reviewers agree the DT 770 Pro is a durable, comfortable and good-value studio workhorse with low distortion. RTINGS measured a bright tuning whose prominent treble can tire over long sessions but helps with editing, while MusicRadar found it neutral; MusicRadar also found it bulky and not built for travel, as it doesn't fold.
