This means that adapters have to be purchased in order to use accessories etc. The USB Type C to 3.5mm audio splitter cable splits an audio signal over two sockets for use with 3.5mm stereo equipment.PLEASE NOTE: This audio adapter will not work with phones/tablets etc that have a 3.5mm port as well as a USB C Port, the phones cannot detect the USB C adapter and defaults to speaker.USB Type C to 3.5mm audio splitter cableUSB Type C maleTwo 3.5mm stereo socketsSupports 16bit 44.1KHz
