I own a pair of Audio Technica ATH M50s and they are in the same price backet as the ones you posted. Great sounding pair for the price and they're solidly built.
It really depends what you're looking for in your music taste. Check a forum called head fi for reviews on each headphone you are looking at. It will give you the sound signature and pros/cons for each headphone. If possible try to test them out at your local electronics retailer.
