Just as an opposing viewpoint, I have a few pairs of those Extreme Isolation cans, and as corny as they look, they seem to be pretty popular with the drummers. They sound decent, they are cheap, and the really do isolate, and to top it all of they are pretty comfortable.
In addition, they were just recently redesigned with better drivers and better cables which makes them more reliable in a studio situation. Plus, the owner there is really great and provides excellent customer support. I blew out 2 of the older designs with the lower impedance drivers, and he replaced them, "no questions asked". The newer design with the higher impedance drivers are much more robust, and are pretty much impossible to blow out, even with deaf drummers!
