EP-T21 - Windows doesn't recognise as an audio device

Hi! I just received my EP-T21 yesterday. I seem to have successfully paired them with my laptop (Windows 10), however, they appear as ‘other’ rather than ‘audio’ so I don’t seem to be able to select them for use as headphones.

I’ve unlinked and retried, restarted my laptop and retried, but no luck. They seem to work just fine with my phone (which I’ve since unpaired from, to avoid confusion).

I’d really like to be able to use these ASAP for work calls etc. so any help is very much appreciated!
