I bought the Bose in-ear headphones about two weeks ago and just returned them today. They were good headphones, but not good enough that I'd pay $100 for them! They only rest in in your ear and they don't clog em, so if you're the type to like regular headphones and not actually IN ear headphones you might like these. They don't block off any noise and the base of these headphones are CRAZY, the treble isn't that great though. I returned them today and got the Bose around-ear headphones.
These headphones are GREAT! The fact that they are around your ear, they block off a good amount of noise. The treble and bass ratio is good! My only complaint is that the wire is SUPER long and there are some cons the fact that it's around the ear. It'll be hard to listen to music with these while I'm in my bed sleeping or if I'm in the car because I like to sleep with my head on the side!
If you're going to get Bose headphones I recommend you go to an actual Bose store because they give you a 30 day trial, if you don't like em, return em! They also have a year waranty which I was really satisfied with because my main concern was the headphones breaking since I don't really take that much care of my stuff.
