A set of high quality sounding headphones for a very decent cost are the Superlux hd681. Build quality is on par for the cost, but the sound is phenomenal. They have a huge sound stage and on the razr maxx sound terrific. If you want a set of great sounding cans and don't want to break the bank, I highly suggest these.
