No sound from one side of the earphones
If no sound is heard from one side of the earphones, restoring the settings of the earphones to the initial state may solve the problem.
Follow the steps below to check whether there is any abnormality with the sound output.
Restoring settings to the initial state
Insert the earphones into the charging case
Press and hold the button on both sides of the earphones for about 15 seconds to initialize
Delete the registration information of the earphones from the BLUETOOTH® settings
Remove both earphones from the charging case at the same time and place them back in again
After the indicators on the earphones and charging case are lit, remove both sides of the earphones at the same time
After a few seconds, the indicators on the earphones and charging case will turn on.
After pressing and holding the button for 10 seconds, the indicator “flashes once”. Continue pressing for another 5 seconds until the indicator “flashes once” again.
If you release your finger before the second time the indicator “flashes once”, initialization will not be complete.
If you released your finger too early, perform the initialization process again from the start.
Check that indicators on both earphones are turned off before performing the next operation.
The L and R sides are automatically connected to each other, and the earphones are restored to the initial settings.
After taking out the earphones, move the L and R earphones close to the device to pair with.
Wait for a short while. When the L indicator starts to flash quickly, the earphones are ready for device pairing.
