Overall this headset is one of the best I have owned, and I own quite a few. I have 3 different Jabras, a motorola, another plantronics, and various other off brands. This headset is clear and since it fits directly in the ear, more than loud enough. Pairing is a snap. I am currently using it with my new Samsung a990.The only gripe, which isn't really anything serious is this. I wear the headset in my right ear. While driving at night, the blinking of the device is extremely bright. You can see it through the cabin of the vehicle.
