TWS is the abbreviation of True Wireless Stereo in English, which means true wireless stereo. TWS technology is also based on the development of Bluetooth chip technology. According to its working principle, it means that the mobile phone connects to the main earphone, and then the main earphone quickly connects to the secondary earphone wirelessly, so as to realize the wireless separation of the left and right channels of Bluetooth.
