TWS is the abbreviation of True Wireless Stereo, which means True Wireless Stereo. TWS technology is also based on the development of Bluetooth chip technology. According to its working principle, the mobile phone is connected to the main earphone, and then the main earphone is connected to the secondary earphone in a wireless way, so as to realize the real wireless separation of bluetooth left and right channels. When the slave speaker is not connected, the master speaker returns to mono sound quality. In TWS earphone, the circuit is divided into two parts: charging bin and earphone. SCCB series and SWFI series are recommended to be used in the charging bin, and SDHL series and SZFC series are recommended to be used in the earphone, which can optimize the noise of earphone bottom, inductance noise and other common problems.
