I swear, it sounds like you guys are hearing different headphones than I. I agree that it has better bass than most headphones, but "...less refined..."? "...muddled..."? Nope, didn't hear it that way at all. But then, I heard them from the beginning on some pretty high end gear, so...there ya go. Are you sure you're not just hearing FOTM backlash? You know, just because it's a FOTM, doesn't mean it's bad.
Ben -- at least take the opportunity to hear a pair if you can. I'm not going to say buy a pair outright, because obviously they may not be for you, but don't discount them outright, neither.
