I'm not a Bluetooth techie, so I can't compare this to other headsets, but after a month of ownership, I can say it works great.My car has built-in Bluetooth, but everbody tells me that when I'm in the car it sounds like I'm under water. Not so with the Motorola - I'm told it's crystal-clear.The only negatives I have are:* The multifunction button has no tactile feel - it leads you to press too hard, and too often. This is especially a problem when you're walking or driving.* The flip out mic is nifty, but the headset tends to wobble if you shake your head at all.
