I'm in the exact same boat. The AirPods just fit perfectly like no other pair before but for most of my friends it's the opposite.
I'm intrigued how the AirPods Pro will fit. We will see I guess.
What gives me hope is that they might have used the exact same ear model to build these new ones, so maybe this will be the first pair of rubber earphones I will ever like?
Every other in-ear headphone I've tried has been super painful and falls out at the slightest bump.
