These headphones are really interesting to me. Seem pretty good out of the box, but also probably good for eq. As a side note, I know the headphones.com crew went and got their hrtfs ... done ... in the UK, and found that you can have very different in-ear response between different people, but what frequency range are we talking about? Is it generally 2 KHz and up that the outer ear affects? Just wondering in that review which part of the frequency response is affected by the HRTF compensation and which part is not?
