Frequency response notes
Fairly close to the SoundGuys preference curve. There is a dip between about 50 and 100 Hz and the sub-bass is slightly louder than ideal. The 2 to 8 kHz range is slightly under-emphasised and the response drops steeply above 10 kHz.13Reviewsoundguys.com/sennheiser-hd-280-pro-review-53109Read 23 October 2026SoundGuys measured response compared with its headphone preference curve.
