I find the fit of the supplied earphone sleeves supplied with my AirPod 2 Pro's totally unsatisfactory. Normally this would not be and issue as as I have a soft case full of them, many different types and sizes. Naturally Apple has its own design. As it is I cannot wear them because they are not securely fitted in my ears, specifically my right ear I have had the right earpiece fall out twice and that sitting at my desk, fortunately. I more or less like their sound but I am not going to use them out in the wild until I can securely anchor them in my ears. I have tried the add on ear hooks and lanyards which ruins their fit and comfort. The one thing I can see doing is getting them custom fitted. Has anyone done this. You can get kits that allow you to take a mold of your auditory canal which you send in for custom fitted ear sleeves. My problem is this costs more the $150 bucks. These AirPod are not that good, I have perfectly fitted Shure SE-425's and 535's that blow the AirPods out of the water sound wise, they just don't have the Apple ecosystem goodies.
