While I appreciate FLYaway3x's review, I'm still not convinced when it comes to the QC3's. Firstly, the on-ear style is a big negative regardless of the material. There was really no reason for Bose to reduce the ear-cup size. Second, is the need for yet another charger for the battery. I would rather carry four rechargeable AAA's instead.
Here's a question to Bose. Suppose my charger dies while I'm in London? How do I charge my headphones then? It's not like Bose products/accessories are available at your corner electronics store.
