I can't get over how much I love these cans. Except for the slightly bloated bottom, which doesn't reveal itself on most cuts, these sound as good as anything I've heard except crazy expensive stuff like HD800s and the original Orpheus. I like them better than the HD 580/600/650, K/Q701, and Beyer DT-880's, all of which I own now (not for long) or have owned for years. I absolutely love the big, easy spacious sound and the fact that they don't need an amp, which I consider a huge PItA. The proof of how good these are is, I can't take the damn things off! Un-modded they have some serious problems, but switching to the velour pads (included) and removing the foam discs reduces the problems to entirely acceptable levels.
