If for some strange reason your earbuds have become unlinked from each other, here's how to pair them again (to each other).
- On your mobile: Delete previous pairings from: Settings - Bluetooth -- (delete, forget...)
- Put the earbuds in the charging case.
- On your mobile: Turn off Bluetooth.
- Take both earbuds out of the charging case, then press the touch panel of both earbuds 4 times simultaneously.
- Look at the LEDs on the earbuds; they will light up. This means the earbuds have been reset.
