Pros: Great sound, great reputation.
Cons: Cheap components/ plastic where there should be nylon or metal.

Bought these as a gift for my son who loves listening to music on his computer. He's delivered them to me twice in the last month, with the plastic head band in one hand, the earpiece in the other. Cheap plastic headband attachments which can't hold up under stress (I think my plastic spoon in my lunch box is better quality!). I've sent an email to Bose, as I'm not the type that keeps receipts and warranty cards on things I believe to be high quality. My mistake. Would probably be great for a small child, with a small head, who acted like a 60 year old. Anyone with a large head, forget it.
