In this embodiment, each of the Bluetooth host device 110, the first member device 120, and the second member device 130 supports the BLE Audio technology. In this situation, the processing circuit 117 of the Bluetooth host device 110 is further arranged to operably generate audio data complying with related specifications of the BLE Audio technology (hereinafter referred to as BLE audio data), and to operably utilize the host-side communication circuit 111 transmit the BLE audio data to all member devices in the Bluetooth device set 102. The first control circuit 125 of the first member device 120 is further arranged to operably utilize the first audio processing circuit 127 to process the BLE audio data transmitted from the Bluetooth host device 110, and to operably instruct the first audio processing circuit 127 to control the first audio playback circuit 162 to playback the contents of the BLE audio data. Similarly, the second control circuit 135 of the second member device 130 is further arranged to operably utilize the second audio processing circuit 137 to process the BLE audio data transmitted from the Bluetooth host device 110, and to operably instruct the second audio processing circuit 137 to control the second audio playback circuit 172 to playback the contents of the BLE audio data.
