Excellent! Wonderful sound on music with real solid bass. These headphones actually are just -1dB @ 20Hz - a very rare thing depite abundant false claims! The 3dB peak @ 100Hz is tolerable, and better than most. The dip at 8kHz is a 'design feature' necessary in a good headphone to compensate for difference between side and frontal presentation. It has to be a compromise as this difference varies between people, but listening tests on tones suggest this is pretty effective for me.

Some headphones fail to come back above 10kHz, others have peaks in the HF too.

Overall sound on these is the best I have found.

Measured using modified Lindos MM3 mic built into earplug - ear canal closed off.
