I'm working on a PhD in metallurgy... Cables make me weep.

I never was much of a believer in burn-in, but after now listening to many headphones I've heard characteristics of headphones change over time. Not every headphone benefits, but some definitely do. For full-sized headphones though I don't think people give pad break-in enough credit.
Absolutely. Changes in the pads will alter the angle and distance to the ear, and in the case of supraaural pads will also affect your ear shape. In addition to the psychological affects of comfort on audio, all these can have a profound effect on perceived audio quality.
I have personally yet to hear any significant change in sound due to driver burn-in.

Oh well haters will be haters and a fool is soon parted from his money.
