I find the Motorola HS820 headset to be fine if not good. It does exactly what it says it should. It is a bluetooth headset, no more, no less. The range is good and I can here the people I'm calling very clearly and they can hear me. Battery life? it lasts a good two days I would not know as I charge mine every night when I'm not using it. I reccomend to anybody, with headsets, phones whatever, don't complain about batterry time, just frequently charge the thing. Overall a good headset.
