Wireless Data

I have the HS850 (after an HS820) and still find the volume way too soft to hear, especially in a car. I know the new H700 isn't out yet but was wondering if anyone has heard anything about whether the volume would be better? I cannot believe when they design those at Moto a committee listens to it, tests it, and then says, "Oh ya, that volume is plenty loud". I have good hearing and I have to strain to hear what the other person is saying! Thanks, Cory
