Overview of the LED indications of the
charging case
When a USB cable is connected or the charging case is placed on a
wireless charging station, the LED of the charging case permanently
displays the charging process:
If you open the lid of the charging case and no USB cable is con-
nected or the charging case is not placed on a wireless charging sta-
tion, the LED of the charging case displays the battery charge status
or the charging process of the earbuds. If you close the lid of the
charging case, the LED will go off after 5 seconds.
