Bluetooth is an industrial specification for wireless personal area networks (PANs) which offer a way to connect and swap information between devices such as mobile phones, laptops, PCs, printers, digital cameras, and video game consoles over a secure, globally unlicensed short-range radio frequency.

BLUETOOTH HEADSET APPLICATIONS
Today, the Bluetooth technology is implemented in a variety of new products such as phones, printers, modems, headsets & Bluetooth for cars. Bluetooth is acceptable for situations when two or more devices are in proximity to each other and don't require high bandwidth. Bluetooth is most commonly used with phones and hand-held computing devices, either using a Bluetooth headset or transferring files from phones/PDAs to computers.

TYPES OF BLUETOOTH HEADSETS
Bluetooth wireless headsets can typically be classified into three general categories as:

	The ear bud headset is a headset having a wire connection to the base unit. These have the speaker encased in a cylindrical casing designed to be positioned in the opening of the auditory canal of a user's ear.
	These are offered as an alternative to ear bud headsets & these utilize speakers that rest on the ear.
