Pros: Everything, Sound is awesome, quality is good too
Cons: They are expensive, but for what you are getting they are not.

I really think that these headphones are awesome. I am fortunate enough to own a Bose portable CD Player (Fortunate because they didn't make that many). The two of them together gives you an unbelievable sound experience. Put them on, close your eyes, you'd swear you were listening to Large tower speakers an a sub-woofer.
