The earbuds are magnetically pulled into the charging compart­ments.

2.Connect the USB-C connector of the USB cable to the USB-C socket of the charging case.

3.Connect the USB-A connector to a corresponding socket of a USB power source (to be ordered separately). Make sure that the USB power source is connected to the power supply system.
