I currently have the H700, and can hear people well enough, but it continually moves on my ear and people a CONSTANTLY telling me I sound EXTREMELY quite even when I am driving with the windows up and the radio off.
the 3 main features the BT MUST have are:
1. stays in place, I am constantly moving, indoors outdoors and since I am in TX the BT MUST be able to withstand sweating
2. Must be REALLY good at canceling ambient noise
3. and of course work with the BEST phone ever!!!!!!!!!!!
(6800 if you weren't sure)
I really don't care if it is one that goes into the ear or hook over the ear.
