I took back my $350 Beats by Dre Studios for a pair of Audio Technica ATH-M50s after some strong recommendations from the folks at head-fi.org. They're one of the best purchases I've made in the last few years, they're that good.
Also - I abuse the crap out of these. They're very durable.
I found recertified ones for $105. I guarantee you won't find anything near as good as these for that price.
