A few years ago some colleagues and I created a SOFA format for headphone transfer functions and put several different databases together so you can compare the effect of inter-subject and intra-subject variation in frequency responses for different sets of headphones. We had relatively good results applying a regularized equalization to HD650s, but there is a lot of variation between subjects and even for different seatings of the same headphones on the same subject above 4 kHz. When you equalize the headphones without regularization, these high-frequency notches often move slightly and the peak introduced by the EQ ends up sounding like a distortion effect. This can certainly harm good localization, but is also just really distracting in general and reduces the quality of the audio greatly.
