This bluetooth headset perfectly meets my expectations! Incredibly easy to use and setup (it took me 5 minutes to pair two phones) I recommend this product to those who, like me, often take the road with one or two phones (professional & personal example). Personally, I use a Samsung Galaxy S2 and a BlackBerry Curve and everything works perfectly, I switch from one phone to another with ease, seamlessly and transparently. The sound quality is good and it seems that the humbucker optimizes my voice on the other side ... Only flat, the voice, which is a little robot ...
