I have a Motorola V710. I was searching for a perfect bluetooth headset for my mobile. I have tried one from I/O Gear and one from BodyGlove and both of them sucked. The audio quality was bad and all that. Finally I found this. Now my friends say they can hear me loud and clear. It is really convenient. Only drawback is that if you wear it for too long it hurts because the ear clip is a little too tight. Other than that it is quite good for its price.
