Welcome to Community@Insignia!
Generally speaking, the USB port on a TV may be used by technicians to access important functions during repairs, or used by consumers for JPEG image playback. In such case, connecting headphones by USB would not work.
With that said, I'll be happy to look into this for you if you will please reply with your Insignia product model number. Additionally, the TV model number would be helpful.
Thank you for writing to us.

Thank you for sharing the requested information.
I was able to inspect the TV User Manual which confirms that the USB port for this TV is for JPEG photo playback and service only.
As you mentioned, the TV has no audio output, so the Insignia headphones do not appear to be compatible with your TV. However, if you have a sound bar or other home theater audio system, you may be able to connect your headphones by that means. You can find more information on connecting these headphones to your devices in the headphones User Manual.
I regret I don't have better news, but I hope this helps.
