- Make sure that the earbud is seated properly in the charging case.
- Close the case, Confirm that the red LED turns on while charging.
Once charged, if the earbud is still not functioning, test if you hear sound when using the touch sensor on the non-functioning earbud.

Reset to the default factory settings.
- Ensure that you charge both earbuds before restoring them to their factory settings.
- Take the right earbud out of the charging case. Once the LED light has turned blue, touch and hold the touch sensor(on the right earbud) for roughly 7 seconds. The earbud's LED will alternate between blue and red.
- Within 1-2 seconds from performing step 2, touch and hold the right earbud's touch sensor for about 10 seconds. The earbud's blue LED will blink rapidly, and when the power turns off, the right earbud will return to it's original factory settings.
- Repeat steps 1 to 3 with the left earbud to complete the factory resetting process.
