What do I do if the battery level indicators on my MW09 True Wireless Earphones case are not lighting up?

First, make sure your case is fully charged. 

1. To charge your case via wired charging, plug the USB-C cable into the right side of the case, and the other end into a power source. 
2. To charge wirelessly, center your earphone charging case on a wireless charging pad with the LEDs facing upwards. 
3. If the case does not appear to be charging, check to make sure the cable is secure, and try another cable/charging source, if possible. 
4. If the case still does not charge, please see this article. 

Next, make sure the earphones are properly placed inside the charging case. “L” represents placement for the left earphone and “R” for the right earphone.

Make sure the charging pads on the earphones and charging pins in the case are clean, and that there is no other debris in the case. Use a damp Q-tip or damp cloth to lightly rub the charging pads and pins.

If the earphones still have battery life, but the charging case battery is depleted when the earphones are placed inside the case and the lid is closed, the indicator lights will not illuminate to display the battery level status.
