Oh, I know how annoying this is! I've been there. Here is my guess. you used the AirPods. You may have had some wax build up. It got compacted. This can cause that plugged up feeling that also distorts your hearing and then can create ringing. https://www.medicalnewstoday.com/articles/ear-feels-clogged-and-ringing#earwax-impaction I'd get some debrox and try to see if that helps. (at any drug store, follow directions. Safe for babies, safe for everyone). If that doesn't solve it, sure you aren't getting an ear infection? But I had this for a different reason which was issues with my Eustachian tube. Try the earwax fix first. Let me know.
