Please follow the steps below to perform a reset. It should resolve products such as;

- One side no sound

- Unstable Bluetooth connection


Steps:


1. Turn off the Bluetooth function on your phone/tablet, and also on any close-by devices to avoid accidental pairing.


2. Insert the earphones into the charging case and touch and hold the right and the left touch control panel for at least 9 seconds. You will see LED blink at the 6th seconds and it blinks again at the 9th seconds. (Anything stored in the memory will be cleared from the earphones.)


3. Take out the earphones from the case and keep the left and right earphones very close to each other (less than 10cm) for the left and right side pair with each other. The LED of one earphone will change from fast blinking to slow blinking. The LED of the other earphone will change from fast blinking to off.


4. Pairing is successful when you hear "earbuds paired". 


5. Lastly, pair your earphones with your Bluetooth device again.
