Sooo this is a really dumb feature. BUT you can't use the mic on the headphones to record audio because the phone itself doesn't have an option to use an external mic. So unless the app you're using has that option, it won't work. You can't use external mics to record audio on the default camera app either. It's a really stupid feature of these phones. I just talked to customer support and they said there are regional laws prohibiting it, but I'm not sure if thats true. They also said the OnePlus 8 series does work with external mics but everything I've seen online states otherwise. I'm going to order one and will try to remember to keep you guys updated. If it doesn't work I'm sending it back and going to iPhone haha.
Here is a way to make third party mics to work, you need an adapter and to use a different camera app
