As far as bluetooth headsets go, there are a ton of great ones to choose from. It just all depends on what you are looking for. The Plantronics Voyager Pro+ is great because of it’s battery life.
I decided to test this one on a road trip with it connected to my primary phone using GPS. This headset made it through a 12 hour drive without dying. For me this was really impressive so I decided to test it a little further. While spend 3 Days of being away from chargers other than at night I wore this headset from 11AM until about 2AM. I only had to charge this headset once in that 3 days. That is with streaming music, making phone calls and using GPS all day long.
It is quoted at having 6 hours of talk time and 6 days of standby time. If you are looking for battery life without losing features this is the way to go. It completely supports AD2P, and has 2 microphone noise cancellation with audioiQ2 technology, and comes with Plantronics Vocalyst for one year for free. The MSR of this headset is $99.99 which is not bad at all for what you are getting.
