Hello tamifrombenicia,
I know this can be really frustrating, especially for the price point of the AirPods. Currently Apple isn’t selling any accessories for the AirPods, so I suggest purchasing trustworthy third party accessories. I bought the AirPods too, and they were always falling out. So I purchased Earhoox 2.0, they hold them securely in your ear with a comfy fit. They are $10.00 and you can choose from black, white, and blue. You can take a look at earhoox.com.
I hope I pointed you in the right direction!
