I currently own the Bose, Jawbone Icon, Blue Ant Q3. I have the new Jawbone ERA coming today actually.
My experience:
Bose sounded the best but had no battery indicator on phone (which i like). Also had no way to control music (start/stop). Not the loudest but sufficient. Really liked the ear gel.
Jawbone Icon had the best noise cancellation but was low volume and lots of crackle. Did not find it comfy.
Blue Any is the best all around (currently using). Has battery indicator for phone, volume control on device, and can use with music. Very good noise cancellation and decently loud. But the fit is the worst of the three. I don't like the earloops as i find it moves around and takes longer to put on. The included ear piece is supposedly able to be used without loop but it never stays put.
