I have a BlueAnt z9, which I DON'T recommend. It's rated up there with the Jawbone, can pair with 3 devices which is nice, but the noise reduction doesn't work well in any kinda of breezy outdoor setting, and people complain of a constant hiss during calls. It doesn't fit snugly in your ear, and the range of sound sounds like someone talking thru a paper cup. You also need to hold the multifunction button for *THREE* seconds to end a call. If you don't plan on using it outdoors, it's ok. It comes with a USB pigtail you can charge with on any USB port, and a wall charger. I have the 3.4 firmware.
