Well known market players Bang & Olufsen have reinvented themselves with the chic and modern design of the Earset 2. The aluminum-clad headset, apparently features two microphones and some newfangled gadgetry to optimize the transmitted sound quality (think bone conduction, but with less bone conduction and more microphones). Finally this one is equipped with BlueTooth. The features include dial microphones and a form of intelligent voice-isolating technology. Battery life is estimated to last up to 4 hours for talk time, while standby time is 25 times that amount.
