<$150 Headphone Suggestions

I'd just like some suggestions on headphones that are less than $150 (preferably). I've been looking at the ath-m50's.

what do you do? do you care about noise isolation?

Ya If anything I would look into the ath-m50s. I don't have a pair myself, but I've heard a lot of good reviews about them.

I picked up a set of the m50s on ebay for $115 brand new. A shame that people are paying 150-170 on Newegg/ Amazon :/
