Hey JP,
We're glad you thought to ask Apple Support Communities about using Headphone Accommodations and the audiogram feature. The following resource has some great information on this feature, and which headphones are compatible. Your AirPods Pro are on the list, so no worries there: Customize headphone audio levels on your iPhone or iPad
We also thought the following resources would be helpful:
Hearing accessibility features in iOS
Use Made for iPhone hearing devices
Made for iPhone compatible hearing devices
Use Live Listen with Made for iPhone hearing aids
For additional assistance with these great features, reach Apple Support using these steps, if needed: How to contact Apple for accessibility support
We hope this information helps. Thanks again, and have a wonderful day!
