Adaptive Transparency is such a promising feature. I would love if transparency mode could eliminate the sound of noises like air conditioners, road noise, and construction while still being "transparent". It seems that, as of now, it's limited to loud noises only.
I hope it at least eliminates the hear-loss-causing pops that occur when you have loud, brief clicking noises like that of a bug zapper. For older models, you should never use the Airpods next to a bug zapper. I learned the hard way, in the form of tinnitus.
