A:AnswerThis controller does not have a 3.5mm audio jack to plug into the controller. It only has a USB-C port for the charging cable. There may be compatible USB-C headsets but I would recommend using either a wireless headset that connects directly to the Switch by bluetooth or one that connects by USB-A dongle. If you need to use a 3.5mm audio cable, find a 3.5-to-usbc adapter and try that for the USB-C port on the controller or a 3.5-to-bluetooth and pair that to the Switch.
