      Note: The following procedure uses WF-C700N images for reference.

      1. Clean the earbuds, inside the charging case, and the charging port of the earbuds, and then check the indicator of the charging case.

        Make sure the earbuds are properly inserted into the charging case.

        Charging may fail if the earbuds aren't touching the charging case or if the charging port is dirty.

        After cleaning the earbuds, the inside of the charging case, and the charging port of the earbuds, set the earbuds into the charging case, and without connecting the charging cable, check the indicator of the charging case. For details on how to clean the earbuds, refer to our headphone cleaning and maintenance article.
        Note: When cleaning, do not use compressed air to remove dust. This can cause dust to get into the microphone or sound outlet holes, leading to malfunction.

        Hints: Check again that the earbuds are properly inserted and not floating in the charging case.
