The Bluetooth headset is the application of Bluetooth technology to the hands-free headset, allowing users to avoid the annoyance of wires and easily communicate in various ways. Since the advent of Bluetooth headsets, it has been a good tool for the mobile business community to increase its efficiency.
Bluetooth is a low-cost, high-capacity short-range wireless communication specification. A Bluetooth laptop is a laptop with Bluetooth wireless communication capabilities. The Bluetooth name has a legend. In the 10th century AD, the Nordic princes fought for hegemony and the Danish king stepped forward. With his tireless efforts, the bloody war was stopped and all parties sat down at the negotiating table. Through communication, the princes were unknowing and became friends. Because the Danish king loves to eat blue plum, so that the teeth are dyed blue, known as Bluetooth King, so Bluetooth has become synonymous with communication. A thousand years later, when the new wireless communication specification was introduced, people used Bluetooth to name it.
