First and foremost, this is a very comfortable headset. It is also quite intuitive to use and the sound quality is good. Set-up was quick, and instructions are clear and straight-forward. My only complaint is that unlike my last Bluetooth headset, it does not pass voice-dial commands to the phone.  (At least I haven't figured out how to do it!)  It would be nice to be able to tap the button, speak a command, and have the phone dial.  But in the grand scheme of things, not such a huge deal.
