The Bluetooth headset not only liberates people's hands, but also avoids the pain of the hands and neck brought by people when they hold the phone for a long time, and can also effectively reduce the harm of electromagnetic waves to the human body. Since the advent of Bluetooth headsets, Bluetooth headsets have been a good tool for mobile business people to improve their efficiency. In 1995, Ericsson first proposed the concept of Bluetooth. The Bluetooth specification uses the microwave frequency band, the transmission rate is 1M bytes per second, the maximum transmission distance is 10 meters, and the transmission power can reach 100 meters by increasing the transmission power. Bluetooth technology is globally open, with good compatibility on a global scale, and the world can be connected through a low-cost invisible Bluetooth network.
