Which Airpods Pro Model fits similarly to the Airpods 1st Gen?

Hi, I currently have the Airpods 1st gen and they fit absolutely perfect in my ears, but the battery is at its limit.

I tested the Airpods 3 but they fell out of my ears immediately.

I don‘t really need noice cancellation and stuff but it would be nice to have ofc.

So my question is which model I should consider testing and what tipsize would be the best in my case, maybe someone has the same problem as me.
