The integrated USB socket, of course, has another function - it charges the headset as it's connected. It's not the only headset to do this, but it is convenient and saves on having to remember to take a cable, docking station or charger with you on holidays or business trips. Its integrated battery offers a claimed six hours of talk time, and 10 days standby per charge, so it should outlast the great majority of 3G based smartphones.
It's also good to see that the lid and body of the headset are permanently linked together by a short plastic tether, which extends neatly from the interior of the BIZZ's body when you separate the two halves of the headset. Though you may very well lose the headset, you won't end up with just one half in your pocket, searching for the other.
The BIZZ is not as good looking as the Aliph Jawbone, with its leather ear hook and diamond pattern finish, but it's far from ugly. I've seen people wandering around the local supermarket with things plugged into their ears that make them look like extras from the original Star Trek series - complete with bulky bodies, and blinking lights bright enough to land a 737.
The BIZZ's black and silver livery is tasteful and its slender and wiry black ear hook that tucks away neatly out of sight is the opposite of this. It's also very small and light. Instead of extending halfway down your cheek towards your mouth, the body of the headset measures a mere 52mm, front to back, and weighs just 10g.
