Super Bluetooth
Once two or more BT devices are connected, Super Bluetooth will be enabling
you to adjust the volume and audio balance of each BT device, and calibrate a
connected speaker to better synchronize sound with the video on your smartphone.
To get a better listening experience, we suggest that your device connects with up
to four audio devices simultaneously.
A calibration reminder will pop up every time a connected Bluetooth speaker
changes. A third or fourth Bluetooth device can only be added if you are
connected to a 5GHz Wi-Fi network.

differently.
