The Wall Street Journal recently looked at the "etiquette quandaries" caused by Bluetooth-enabled wireless headsets. Not only do people wearing the headsets sometimes look ridiculous ("you look like a half-assimilated Borg"), social mix-ups are now commonplace, especially in busy urban environments like New York. If you happen to bump into someonone and are not aware that the other person is wearing a "robotic-looking" phone headset, the chance encounter could quickly turn into a comedy of errors. Anyway, these Bluetooth-enabled headsets range in price anywhere from $30-$150, and now there are even super high-end headsets for the fashion-conscious that are closer to $300 each. In fact, Oakley and Motorola recently teamed up to make a wireless bluetooth headset that clips on to Oakley's sunglasses.
