I personally use H700, its a step higher and usually found for a $100 at local retailers, but is the best in my opinion, especially for my Razor v3. Honestly i haven't tried any others with my phones but one i connected h700 to vx8500 there was a noticeable difference, so i would stick with a same manufacturer. in any case, 700 is like h850, but smaller and a bit more pricey, but awesome
I'm looking for a headset to go with my Razr V3 that doesn't sound like you're talking on a headset. I don't care if it's Bluetooth or not; I have ordered an adapter to allow me to use a 2.5 mm headset plug.
I tried the Motorola bluetooth H650, I believe, but was told my voice sounded "distant."
I assume a headset with a boom mike would provide the best clarity to the person I'm speaking with. I want to talk mainly while driving.
