V-Moda M80s or Monster DNA...both fantastic with a slight edge to the DNAs for comfort.  Edge to M80s for durability though, so depends on your priorities.  Both sound awesome so you can't go wrong with either.

I found the M-80s new at radioshack for $129 a couple weeks ago.

Sennheiser HD25-1 II. Use mine constantly and couldn't be more satisfied. Light, rugged, good isolation, and they sound fantastic. Plenty DJs use these, as well. My buddy who's a DJ loves his.

The Philips Downtown headphones are pretty good too.  They feel really comfortable and sounds quite good for a $30 headphone.  Isolation is really good too .

Get the JVC HAS400. It is only around $25 and has great detail.
