Airpod Pro 1 having a crackling sound when I wear them

I have recently encountered the issue of my Airpods Pro Gen 1 having some sort of crackling sound only when I talk, and it is only on the left earbud. I have tried cleaning the bud and the case but it doesn't seem to work. Has anyone gone through this problem before? It has been bothering me because when I talk to people with them on, I get a weird crackling sound in my left ear from the bud.
