A:Answer Included is a very short USB-C to USB-C cable intended for charging, and a 3.5mm headphone cable for connection to other devices.
Use caution with the "not allowing wireless" part - if you are not allowed to connect wireless devices to your computer then you should be fine, but even when plugged in these headphones still have the ability to transmit and receive signals, so these headphones should not be used in a totally locked down wireless environment.
