Basically echoes my experience with them.  Also, it probably helped that I was either driving them with GS-X or B22, IIRC. 
 
  
Yeah, I doubt I would have been able to use mine if I had more hair (I shave my head regularly), as my head is definitely on the big side.  They did give me a bit of a headache if wore them too long, though to be fair, most headphones give me headache with the exception of Grados.
