From Cnet (Rated 4/5-Excellent):
“-The bottom line: Not only is the Aliph Jawbone Icon attractive and affordable with great call quality, but it is also highly customizable with advanced features that makes it the most innovative Bluetooth headset we’ve seen to date.
-One of the first headsets in the world to have a built-in “operating system.” This internal chip can be programmed to provide a far richer experience than other headsets can; for example, this lets it have a visual battery meter right next to the one on the iPhone.
-It can answer, reject, and end calls, plus it has last number redial, voice dialing support, call mute, and multipoint technology that lets it connect up to two devices simultaneously.
It now has spoken alerts and custom audio tones for certain functions. For example, it’ll read out incoming caller ID, and when you press the Talk button while not on a call it’ll tell you the estimated remaining battery life.”
