Welcome to TuFang Store-Bluetooth HeadphonesThe Bluetooth headset is the application of Bluetooth technology to the hands-free headset, allowing users to avoid the entanglement of annoying wires and easily communicate in various ways. Since the advent of Bluetooth headsets, it has been a good tool for mobile business people to improve efficiency.A Bluetooth laptop is a laptop with Bluetooth wireless communication function. The name Bluetooth also has a legend. In the 10th century AD, when the Nordic princes were fighting for hegemony, the King of Denmark stepped forward. With his unremitting efforts, the bloody war was stopped, and all parties sat at the negotiating table. Through communication, the feudal lords released their past suspicions and became friends. Because the king of Denmark loves blueberries so much that his teeth are dyed blue, he is called the king of Bluetooth, so Bluetooth has become synonymous with communication. Today, a thousand years later, when a new wireless communication specification is introduced, people use Bluetooth to name it again. In 1995, Ericsson first proposed the concept of Bluetooth. The Bluetooth specification works in the microwave frequency band, the transmission rate is 1M bytes per second, and the maximum transmission distance is 10 meters, which can reach 100 meters by increasing the transmission power. Bluetooth technology is open globally and has good compatibility on a global scale. The whole world can be connected through a low-cost invisible Bluetooth network.
