Tunable transparency mode sounds great, and I wish Apple would do something like this as first-party support.
As a casual trombone player, who often plays in louder settings, the airpods pro are almost excellent hearing protection. Passive (even "audiophile" or "concert") earplugs make me feel like I'm under water. Airpods Pro attenuate a lot of sound but don't feel so unnatural.
Unfortunately, they tend to drop my own sound out of the mix when sounds around me get louder.
I'd love a mode that selectively let in more trombone frequencies, or better, that mixed noise cancellation and transparency to give me more of a studio monitor effect. Maybe the airpods could figure out which sounds were mine via the buzzing sounds that propagate through my head from my lips.
