Hi All, I did try searching for this so I hope I am not repeating. In the manual for the Soundcore2 it tells me to hold down BT button for 2 seconds to Un-pair. When in fact that does not work, but double tapping BT button does. Just thought you would like to know.
You can try it by pressing the volume +/- button at the same time for 3 seconds.
And let see if it's work!
Or just remove from your source device BT list...
Open up BT settings, Look for name you want to remove/impairNext to the name, look for settings icon... Press itThen press UNPAIR
