Got mine today. So far it seems like it does what it says. I wanted the black one to go with my Sprint 8703e Blackberry.
I couln't wait for the shipping, so I got the grey one from Cingular. Had a few problems @first trying to fit the ear loop. It took a few hours to get it just right/ put it on the right way. Once you do it fits nice. Kind of heavy compared to my Plantronics 510. Audio wasn't as good at first since I didn't place the Jawbone as it should be. It needs to thouch your face. Once I got that going it was good. Did a few calls with some music in the background and the other side couldn't hear any music. Now to wait for Aliph to start shipping my black headsets. Price, $119 retail.
