Hello OneRonPolicy,
Thank you for reaching out to Apple Support Communities, and we'll be happy to help in any way we can. We understand you're having issues with the fit of your AirPods. You can find the best tips for your ears using this information: Choose your AirPods Pro ear tips and use the Ear Tip Fit Test - Apple Support
"Choose the best ear tip size
Your ear tips should make a good seal with your ear canal. When the fit is right, you experience better noise cancellation, and music has a rich bass sound.

Your AirPods Pro come with three sizes of ear tips. The medium size comes already attached, and small and large sizes are in the box that your AirPods Pro came in, under the tray, nested inside the charging cable. To check the size of an ear tip, unroll its edge and look for S, M, or L etched on the inside of the ear tip near its base.
Try inserting the AirPods with the medium-sized ear tips in your ears so that the AirPods are seated comfortably and securely. If you can’t get a good seal, try adjusting the AirPod or switch to a larger ear tip. If the ear tip feels too large in your ear or is uncomfortable, try a smaller ear tip."
While we can't speculate as to how many drops they can withstand, we recommend keeping it from happening so you don't have to find out.
We hope this helps.
Cheers!
