Bluetooth cell phones and Bluetooth headsets communicate in a short-range radio frequency with each other, making your cell phone completely hands free. A Bluetooth headset have a fairly decent range of coverage at around 30 feet or 10 meters.
Of course Bluetooth headsets can be only used with Bluetooth enabled cell phones.

The Bluetooth headsets come in two main flavors:

• With Booms using a traditional earpiece, the microphone is arched toward the mouth, separate from the earpiece.
• No booms or sometimes referred to as boomless Bluetooth headsets, the microphone is located on the earpiece.
