I have tested the Bose QC3 and newly released QC15 headphones at the Apple store. They sound great, but man, $300-$400? Anyone know of any models (not necessarily Bose) that has great sound (especially bass) that are more in the $100-$200 range?

Ive heard Sennheiser makes great headphones, but besides the Apple store, I dont know any business that have headphones out so they can be tested.

Thanks
