Why won't my USB c headphones work on my new s21

Can anyone tell me plz why my USB c headphones won't work

Hi
The Galaxy S21 doesn’t come with a headphone jack
But if you have a usb connecter click on the get help button At the bottom of the page And run a diagnostic test

You would need usb connection
