Try to avoid wearing headphones as they aren’t particularly sexy. The room doesn’t need to be bright, you just need to focus soft light onto your body.
You can do this by making your computer screen a little brighter than usual and turning off the main light in your room.
99% of computers have decent microphones built in, so that’s one half of the problem taken care of. In the ideal situation, you will both be in a private place so that you can turn up the volume and hear every little detail of what both of you are doing.
But if you are in a place where you need to be quiet, then earbuds are the best option, not big headphones!
So higher quality pictures are what you should be aiming for.
