seriously guys, he asks for headphones with the best sound for his budget; he doesn't care about the look and you're still talking bout skullcandy?!
skullcandy = cool looks not cool sound
So far what has been mentioned sennheiser and JVC make real quality headphones but i'm fairly sure that for 250dollar you're just in the price range for a beyer dynamics DT 770
and really, these headphones have better sound quality then some recording studios headphones; if you have a trained ear you can even hear the flaws on professional recordings; by example a squeeking chair or coughing in the background, it's quite scary what you can hear through these babies...
if you're really a music person who enjoys listening a lot and has an ear for detail and can appreciate this; go for a beyer dynamics; every other headphone you'll wear after wearing a beyer dynamics will sound like crap....

i know in the shop they're priced 300 dollar but i've seen them going out for around 200; so if you can find a pair; don't hesitate!
good luck and don't let anyone tell you otherwise untill they themselves have tried a pair of beyer dynamics....
