The Plantronics 5200, the newer version of the Legend, has the LOUDEST audio of any BT headset I have tested, pairs with Motorolas as well. The Voyager also pairs, but the audio output is a lot weaker. I know the Jabras also pair with my Moto. My Moto will also pair to my AVR, my TV, my Macbook etc, but besides pairing, it has no functionality with those devices...it hates my cars also.
