I returned this product because of the excessive static and low volume. Callers couldn't hear me well, nor could I them. I ended up getting the Jawbone Aliph, which is sigificantly heavier, but at least everyone can hear me, there is no more static, and I can hear my callers with reasonable ambient noise levels. I have a blackberry 8830, maybe that's the problem here, but I've found the Moto Bluetooth devices to lack when using with my other previous phones.. . .
