If you encounter connection or pairing issues when using your earbuds, try restarting them by following these steps:
a) Put both earbuds in the charging case, and close the case.
b) Wait for more than 2 minutes.
c) Take your earbuds out of the case. The earbuds have been restarted.
The pairing information is retained even if the earbuds are restarted. The earbuds will automatically connect to the last paired device if taken out of the case.
