For the newbies: What is bluetooth? It is a technology that allows a device such as a mobile phone to be paired with a separate nearby device, usually a speaker or other sound system, to project the audio from your phone to the larger system (or a wire-free headphone set). Projecting an MP3 collection downloaded to a cell phone, for instance, into an automobile’s speaker systems is one such use. Hands-free telephone use is another application.
