AirPods fall out almost immediately for me. AirPods Pro the left pod fits perfectly and stays put but my right pod with any sized tip falls out within minutes. I wish they came with wingtips.
Same here, left stays in, right falls out with both the medium and large tip.

I'm wondering if it the ear canal is dryer than the left side, rather than a different shape.
