Jawbone headsets are mainly marketing - they don't sound any better than any other high end headset.
At the moment, the Plantronics Voyager Pro is probably the best there is. The Motorola HX1 does REAL Jawbone conductivity and sounds fantastic.
The Blue Ant Q1 is not bad, but doesn't sound as good as the Voyager Pro.
If you have $89 to spend - go with the Voyager Pro, you won't regret it.
