    # Simple tool to switch the Creative BT-W5 Bluetooth Audio dongle between AptX Adaptive **Low Latency** or **High Quality** mode.
    # Of course, only works with Bluetooth headphones that support AptX Adaptive, such as the Tranya X3
    # Reverse engineered based on communication between Creative's desktop app for Windows and the BT-W5
