I just bought KRK kns-6400 headphones. I had sennheiser hd 215 and they were amazing but I had to return them because there was static in the left side. They didn't have any more 215's so I got the KRK. They're apparently brand new on the market, I was the first to purchase them from the store. They got their first shipment the day I went in.

These headphones blow the 215's out of the water. more clarity, deeper bass, more power handling. These things can go loud. They're also small and lightweight, far more comfortable than the 215. I'm very happy with them and for the price you can't really get better headphones.
