What is TWS Bluetooth headset? How to apply for SRRC certification of TWS Bluetooth headset?

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.

The relationship between TWS headset and Bluetooth 5.0 technology

The latest Bluetooth headset is compatible with Bluetooth 5.0 technology!

Bluetooth 5.0 is a Bluetooth technology standard proposed by the Bluetooth Technology Alliance in 2016. Bluetooth 5.0 has correspondingly improved and optimized the speed of low-power devices. Bluetooth 5.0 combined with WiFi assists in positioning indoor locations to increase transmission speed and increase effective working distance.

The latest version of Bluetooth 5.0, the core specification of Bluetooth, has significantly improved the transmission capabilities of Bluetooth technology, allowing Bluetooth technology to increase the transmission speed by 2 times, the transmission range by 4 times, and the broadcast data packet by 8 times.
