If you're looking for a bluetooth headset to be hands-free and wire-free in the car, don't waste your money on this one. I find it completely unusable while driving. Even at maximum volume, calls can't be heard over the slightest background or road noise. I find myself holding the headset with my hand, trying to mash it into my ear to hear anything at all, but in fact I might as well be holding the cell phone to my ear. I have no problem hearing the cell phone.
