Does 17.7.1 let you enter the audiogram test result to use the "hearing aid" function? If yes, you are probably right. If not, it is not a hearing aid, just a background noise cancellation. Honest question here because I don't have an airpod pro 2.
Yes it does. It is a hearing aid. Apple the Airpod Pro 2s in September 2022 but they didn't publicise it but let people find out for themselves. What it led to was Apple getting mountains of information from the people who owned them about hearing aids. 150,000 of them. They mentioned it in the Apple iPhone 16 keynote in September.
The AirPods are effectively "tuned" by your audiogram AND they also have excellent noise cancellation and excellent Loud Sound Noise Reduction.
