Set headphone accommodations for AirPods
When you use supported AirPods with iPhone, iPad, or Mac, you can change the accessibility settings for your AirPods to suit your hearing needs. Amplify soft sounds and adjust certain frequencies to help music, movies, phone calls, and podcasts sound more crisp and clear. If you have an audiogram in the Health app 
on iPhone, you can use the audiogram to customize your audio.
