Wobbly AirPods

I love to run, love to listen to podcasts and audiobooks, and love my AirPods Pro (2nd generation with Lightning). However, I’ve continually had an issue with them while running, where the AirPods have a pop to them with the sound. It’s intermittent; happens at least 50% of the time, and doesn’t seem to have any pattern. Imagine running for three miles and hearing a slight percussive bump every second (to the cadence of my stride) against the side of your head. Sometimes its in one ear, sometimes both ears. 

I’ve had the earbuds replaced multiple times, but can’t seem to solve this. If anyone has an answer I’d love help. It’s making me wonder if there’s something better out there.
