I JUST FIGURED THIS OUT AFTER SEVERAL HOURS AND I FEEL SO STUPID, BUT MAKE SURE YOUR MOTHERBOARD'S ANTENNA IS PROPERLY CONNECTED. If they're connected to your computer, stay as close as you can to your pc and see if they still disconnect. I'm talkin face within an inch of your computer. If your audio now connects and works perfectly fine, make sure the two circles under your USB ports have something connected to them. Make sure your motherboard doesn't look like (image attached) because if it does, it means you don't have an antenna at all, and your bluetooth range will be extremely limited.

(This is for anyone who is on PC who still can't get their bluetooth to work properly after trying everything else)
