I recently got my first Bluetooth phone and based on a few reviews I read online and the recommendation of the phone-store owner I picked this headset. I use it with a Motorola Razr. They work together quite well. This is an ear-bud type headset meaning it's slightly less comfortable but far more stable and better sounding than the flat ones. If there were a warning with this headset it would be not to buy it online. Mine came, in a sealed package, with the wrong power adapter. It was very easy to remedy this in the phone store, but would have been difficult had I bought it online.
