Frequency response notes
Strong emphasis in the highest frequencies, which can sound grating. Bass is present but not emphasized as much as on consumer headphones. The mids sit slightly behind the highs. SoundGuys suggests lowering everything above 6 kHz by about 5 dB.7Measurementsoundguys.com/beyerdynamic-dt-770-studio-80ohm-review-15348Read 23 October 2026SoundGuys lab review of the DT 770 PRO with its spec box listing 80 ohm impedance. The frequency response chart is a script chart that did not load, so the text is the source: a very strong emphasis in the highest frequencies, lows not emphasized as much as on consumer headphones, mids a bit behind the highs, and a suggestion to lower everything above 6 kHz by about 5 dB. SoundGuys states no target curve in the text.
