I have two mobile phones paired with the PowerBuds. How can I switch between them?

If you have two mobile phones--A and B, for example both have been paired with the earphones, and you are currently using A but you want to switch to B, do the following:
Open the Bluetooth device list on mobile phone A and disconnect the Amazfit PowerBuds first, then open the Bluetooth device list on mobile phone B to select and connect the Amazfit PowerBuds.
