Audio issues with AirPods

I had an issue for a few days and wanted to see if other have it as well and if there is a solutions.

I use AirPods Pro to watch videos on TikTok and the majority of the video are in mono meaning the sound is in « the middle » but some videos have stereo audio that leans slightly towards the left side and there’s a slight echo to it and I can’t change it. I tried forcing my audio in mono in the accessibility setting in my iPhone but the videos that are stereo sounds weird when I use that option. Am I the only one experiencing that ?
