Bluetooth headset is the application of Bluetooth technology on hands-free headsets, so that users can avoid the annoyance of annoying wires and freely call in various ways. Since the advent of Bluetooth headsets, it has been a good tool for mobile business to improve efficiency.

Bluetooth is a low-cost, large-capacity, short-range wireless communication specification. The name Bluetooth has a legend. In the 10th century AD, when the Northern European princes fought for hegemony, the King of Denmark stood up. With his unremitting efforts, the bloody war was stopped, and all parties sat at the negotiating table. Through communication, the princes released their suspicions and became friends. Because the King of Denmark loves blueberries so much that his teeth are dyed blue, he is known as Bluetooth King, so Bluetooth has become a synonym for communication. Today, a thousand years later, when the new wireless communication specification was introduced, people used Bluetooth to name it. The Bluetooth specification works in the microwave frequency band, with a transmission rate of 1M bytes per second, a maximum transmission distance of 10 meters, and 100 meters by increasing the transmit power. Bluetooth technology is open globally and has good compatibility worldwide. The whole world can be connected through a low-cost invisible Bluetooth network.
