I have the Sprint Optimus S and a Plantronics Voyager 520 bluetooth headset , I use voice commands and voice dialing to make phone calls, etc, etc, and the volume on the voice dialing part is very low in my bluetooth to the point where I can just about barely hear it, and turning up the volume on the bluetooth itself has no effect on the voice dialing part, I've checked all the settings I could see and could not find anyway to turn this up so I can hear it, does anybody know of an app, or someway to make the voice command voice louder.. Thanks
