AirPods Pro Ear Tip Fit Test fail (seal is actually good on both sides)

I purchased a set of AirPods Pro on the day they became available in store. I personally had problems with them. The noise reduction seemed to work sometimes and just stop working and then start working again. Sometimes better in one ear than the other. I found the Ear Tip Fit Test and ran it. Both sides indicated failure. Long story short, I tried every possible combination of tip sizes and was never able to get both to pass the Ear Tip Fit Test. Left would pass and right would fail. I would adjust the right and then the right would pass and the left would fail. Out of frustration I took them into the Apple Store where I purchased them. They had me try the demo pair (which was pre-installed with medium tips on left and right). I paired the store demo AirPods Pro with my iPhone and placed them into my ear. They passed both left and right immediately. I switched to the small tips and tried again. Both sides passed immediately. I switched to the large ear tips and repeated the test. Both sides passed on the first try. I placed the medium demo tips onto my personal AirPods and tried the test 10 times. It failed every single time despite adjusting and pressing them into my ears between tries. At the end of the Genius session - the very nice Apple Store employee took a new pair off the shelf and exchanged them for my bad pair. It was clear that the original pair had some type of issue. If you are having trouble getting your AirPods Pros to pass the Ear Tip Fit Test, I would take them back and exchange them. They are probably defective. I am so happy that Apple fixed the problem as soon as I took it to them.

Your mileage may vary.
