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. When the slave speaker is not connected, the main speaker returns to mono sound quality. TWS technology has been applied to the field of bluetooth headsets, so a new product-TWS bluetooth headset was born.

According to the requirements of the EU WEEE & RoHS directives, domestic qualified third-party testing agencies separate products according to materials and use different materials to detect hazardous substances. The role of RoHS certification is to prevent the incorporation and use of prohibited substances, planned abolished substances, and reduced substances (hazardous substances) in the components and materials of electronic and electrical equipment. Protect the earth\'s environment and reduce the deteriorating impact on the ecosystem, protect human health, and maintain the sustainable and healthy development of human society.
