Hi. I didn't look at the video as I don't go off site to investigate things. But I'd guess it is likely built up wax. They make drops you can put in to help remove it. Don't shove a q tip down there. It's only one ear, by the way? We can get growths there. Or something 'can' get lodged. I really think you need a doctor to take quick look. It's impacting your hearing which is problematic. And you probably know earbuds that go directly in your ears are not great for you. They make kinds that vibrate outside your ear now which are a much better choice. Don't know what you listen to for 14 hours a day but if it is loud, I'd curtail that for the longevity of your hearing. good luck
Hello~I would see a regular ear specialist, you probably have some major wax built up and you need a professional to irrigate them, don't do it yourself, it is not safe and could cause deafness.
