My post was taken down because a similar post was already on but it had no similarity at all it's talking about when touching the earbuds or hair is touching in the earbud or wen taking them off.... my things is where my Airbus pro 3 it's wen the music is loud or a certain level and it's on any mode it makes a high pitch noise like cracking while I have them on without touching nothing
Try resetting the buds in the wear app, then repairing them. If this doesn't work you will need to take them to an authorized service center for them to diagnose them to see if they fail an audio test.
