I have tried a few BT headsets, first the Motorola HS850 two times if the first time wasn't enough, the crackling, gurgling & static was way too much for me.
Then a Jabra 350v works great but has low volume, especially if the car windows are down and the radio is on.
Finally after careful consideration the Plantronics Discovery 640 is perfect for me, loud volume, so loud it will burst your eardrum on the highest setting. Not to mention that I forgot it was in my ear because it's so light. I thought the in your ear plug was going to irritate me but to my surprise the gel plugs is genius.
The Plantronics Discovery 640 is awesome.
