Zivio Boom Bluetooth 2.1+EDR headset with 10-hours of talk time (300 hours standby) is now shipping. The obvious feature here is that extending boom, which grows from a base of 53.5-mm to a delicate 137-mm. That little trick puts the mic directly in front of your hot, steaming chat box which supposedly results in better audio pickup (no yelling!) to the benefit of those on the receiving side of the call (and around you). $130, that's how much.
