AirPods Pro 2 Hearing Assistance Media Assist

Hi RBravenec

welcom to te te Apple (user-to-user) Community!

Re: "When I toggle the Media Assist switch on and off, I hear no change in the music even though I have serious loss of hearing at the higher frequencies".

Am no expert in this area, yet your request deserves some response

Wondering how we can be of assistance, and what you hoped to achieve by toggling Media Assist on and off ..

Eg: .when you first turned on Media Assist, that allowed you to "apply the audio adjustments based on your test results to music and video playing on your device",

Those audio adjustments are likely to be in place ... you may need to turn them off if you no longer want to use Media Assist. I could be wrong.

Apple Support's online article has the details: (Scroll right down to "Set up and use Media Assist"

The hearing-health features are intended for those with "mild to moderate" hearing loss

If you were wanting to make other adjustments to the music you hear.

Above linked article says:

"You can adjust other settings like tone, ambient noise reduction, and Conversation Boost with the Hearing Assistance controls in Control Center. Hearing Assistance controls are automatically added to Control Center when you set up the Hearing Aid feature."

and

"You can adjust settings like amplification level (how much your AirPods amplify the sound around you), left-right balance, tone, and Conversation Boost on iPhone" (The steps for this are given in above article)

Also says:

"Most media apps, like Apple Music or Podcasts, also have their own volume controls, so make sure to check the apps if you're having an issue with the volume of music, video, or other media in your AirPods."

All the best :-)
