In recent years, the Bluetooth headset industry has been unprecedentedly hot. The giants have piled up the Bluetooth headsets. The exterior of the Bluetooth headset has completely abandoned the way of wire connection. The technology is gradually mature and the host can work alone. When you need to turn into two-channel stereo, turn on another earplug to automatically loop back to form a two-channel stereo mode. In different usage scenarios, you can choose to wear single and double ears freely. The product experience is excellent and the usage scene is rich.

In addition to Bluetooth headsets, we also have a variety of options such as USB Type-C and Lightning interface headsets, especially the TWS True Wireless Bluetooth Headset for a completely wireless listening experience.

TWS is the abbreviation of True Wireless Stereo, which means true wireless stereo. The implementation of this technology is based on the development of chip technology. Technically speaking, the mobile phone connects to the main earphone, and then the main earphone connects to the auxiliary earphone wirelessly, thereby realizing the true separation of the left and right channels of the Bluetooth.
