            What is TWS Bluetooth headset

            TWS English: True Wireless Stereo, which means true wireless stereo. The realization of this technology is based on the development of chip technology, which means that the mobile phone is connected to the main speaker through the main speaker, and then the main speaker is connected to the slave speaker through Bluetooth wireless mode to realize the true Bluetooth wireless separation of the left and right channels. When the slave speakers are not connected, the master speakers return to mono sound quality. TWS technology uses the field of Bluetooth headsets, so it also spawned a new product-TWS Bluetooth headsets.
