I love my AirPods Pro, but I don't feel the need to upgrade the earbuds themselves. Since the USB-C port is on the case, you'd think we could just buy a new case... but I'm guessing that's too much to hope for.
It's ridiculously annoying you have to make an appointment, but you can get a replacement case. I haven't checked with how compatible the models are between earbuds and cases. The USB-C replacement case is quoted at $99. The same price as the lightning version.
