It's not the doppler effect that's causing this as there is no relative velocity between your ears and the headphones.

However, this is a real (not imagined) issue. I've brought it up before on a thread about singers singing out of tune in headphones. It seems to have something to do with SPL...the louder the cans, the worse the problem. Who knows, it might be somthing like your mouth and nose need to be exposed to the same relative pressure changes in order to keep the tympanic membranes 'calibrated', but that's just a wild ass guess.
