15. How to switch between both Bluetooth devices when the BTR3 is connected with them simultaneously?

A: When BTR3 is connected with two devices(such as two smart phones) at the same time, it will be automatically switched between both devices by default. That is, after connecting two devices with the BTR3 at the same time via Bluetooth, when you pause music in the first device A, then it will automatically switch to second device B if you start to play music on device B , and vice versa.

When it is set to "Manual"  in FiiO APP,  you could quickly press the BTR3's Power button twice to switch between A/B devices.
