You sir, are blessed to have a steel helix, antihelix and triangular fossa. Not even stretching my K518DJ over a stack of books helped. 
Haha! And just to make you more...jealous, the "drilling-on-the-top-of-your-head" gripe from the SRH750DJ doesn't affect me as well

I think it helped that I got the K81 from bro Erwin, who says that he has a big head, thus, the K81 was stretched over time. However, in the case of the Bose OE, it wasn't to my advantage since it became loose on my head (compared to those available for testing in Apple stores).
Still, it's all cool
