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
Press and hold the button on both sides of the earphones for about 3 seconds to turn off the power
Press and hold the button on both sides of the earphones for about 20 seconds to initialize
Delete the registration information of the earphones from the BLUETOOTH® settings
Insert the earphones into the charging case
After the indicators on the earphones and charging case are lit, remove both sides of the earphones at the same time
The indicators on the earphones light up in red, and the power of the earphones turns off after the red light goes off.
The indicators will flash in white for three times every 10 seconds.
If you release your finger before the second time the indicator flashes three times in white, initialization will not be complete.
If you released your finger too early, perform the initialization process again from the start.
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 for the L indicator to flash quickly and alternately in red and white. The earphones are now ready for device pairing.
