It’s probably a bit niche, and given the vendor probably impossible but… I have a Logitech G935 headset, that I use with my PC. There is a minimally functional open source configuration program to get things like the sidetone/loopback set up on linux but not much more than that. The dongle is a USB-A thing, of course.
IF (and it’s a big if) a dongle for this kind of headset could be made, especially if it could spoof the pairing that goes on in the background for it, that would be great. It’d be a big project because I’m sure Logitech would be no help at all, but it would be pretty great. Well beyond my skill level, though. I should probably just buy a bluetooth headset lol
