Here is Samsung's official use of the USB-C port/connector: Use headphones or audio adapters The Note10 includes AKG headphones that have a USB-C connector. Just connect the headphones into the USB-C port on your phone – the same one your charger goes in. You can also use Bluetooth headphones to listen to everything without wires.
