Slightly bass heavy, but I'm a big fan of the Sony MDR-EX51's. They're nothing amazing, but IMO they're solid performers for a bargain price (if you buy online, in stores they seem to go for $40-$50). Only complaint is that I can't keep the damn silicone tips on them so I have to keep replacing them (using complys now instead).
