I'm looking for some Bluetooth headset. My requirements are: - discrete design. I don't like those weird giant models that make you look like a douche. - good sound quality (please, no ****** bass). - ability to hear my environment. So no in-ear models (and if it has noise-cancellation, I want it to be optional). - buttons: volume up and down, answer/music controls. - good call quality. I want the other person to understand what I'm saying, not hearing the wind. Also a good mic is a must in order to make Siri properly work. - bonus: good battery duration. Btw kind of dumb question: is it possible to use simultaneously a Bluetooth headset and a smart watchboth connected to an iPhone 5? Thanks in advance!
