I have these as well, ordered at the same time as the equivalent 2.0 for my Beats Fit Pro. I've used Comply tips with other earbuds in the past, and always stopped using them after a while - the foam for some reason just didn't stay pliable and would stop staying in my ears. I quickly stopped using the Beats Fit Pro versions for the same reason - though really the silicone tips for the BFP work really well for me, so I'm ok with that.
But the 3.0 tips for the AirPods Pro 2 are fantastic - in fact they make the APP usable for me for anything but sitting still. Once I begin moving around, the AirPods would always start falling out - none of the standard silicon tips work well for me. These Comply tips are great and now I'll use the APP for working around the yard, etc., which I just couldn't do before.
