When I set the WF-1000XM3 earbud headphones in the charging case and close the lid, the red indicator light flashes for about 15 seconds and then turns off

    This is an indication that the remaining battery charge of the charging case is low. Connect the charging case with the supplied USB Type-C™ cable, and finish charging the headphones with the cable connected.
