I had a pair of Sennheiser HD570. I bought this back about 7 years ago and they still sound amazingly good. List price at the time was about $150, but I got it off Ebay for around $80. My friend had a pair of Bose (the collapsible $150 one) that has noise-canceling, but sound-wise my Sennheiser headphone beats that Bose stuff out of the water. I'd recommend any mid/high-end Sennheiser headphones. They are totally worth the money. Especially when you like listening to music with lots of layers and bass. You'll feel the difference right away. Good hunting!
