True Wireless Stereo (TWS) uses Bluetooth signals instead of wires or cables to transfer sound. TWS differs from wireless accessories that do not physically connect to a media source but still rely on physical connections to ensure that multiple parts of a device can function together. It needs the micro battery solution for their products, such as the button cell battery.
