Initializing

If no sound is heard from one side of the earphones or the earphones cannot be connected to your BLUETOOTH device, initializing the earphones may solve the problem.

Information of all the paired devices will be deleted (initialized). Perform pairing again from the start.

Start by deleting the registration information of the System from the BLUETOOTH setting on the BLUETOOTH device.

Charge the charging case beforehand.

Remove the earphones once if they are inserted into the charging case.

Follow the steps below to initialize the settings of both the L and R earphones.

 

Start by initializing the L earphone.
