Yup, that's them. Best bass response I've ever heard in a small headphone. Won't go back to anything else at this point.

Trick is, when you first get them, resist the temptation to jam them into your ears extra tight. I did that at first, and Doug did that at first. You'll irritate your ears that way. They should seal very gently and get good bass without needing to push them in hard or fiddle with them. Just use the correct size rubber gasket.
