CRACKLING WITH IPHONE 12 PRO MAX AND PHONAK HEARING AIDS

Thanks. I just tried:

Settings - General - Transfer or Reset iPhone - Reset - Reset Network Setting

I had to re-connect to my home wi-fi network and re-pair the Phonak hearing aids. The first pairing paired both hearing aids, but I couldn't use them for phone calls. Then Iturned the right hearing aid off and on again while in Settings/Bluetooth. The second time added the 'third' device to allow phone calls using the hearing aids.

The third device is named "R-Phonak hearing aid".

A quick test seems that the crackling is gone. For now, at least.

Thanks again.

A new MyPhonak app was released today. Try it and see if it works with his iPhone 12 to clear up the static.

I have a similar problem with an iPhone 13 paired with Phonak hearing aids, and have been using the new MyPhonak app. Today, my wife could hear me fine, but I could hear crackling when she spoke. Previously, friends heard lots of static and distortion when I called them. When I switched from hearing aids to iPhone audio, all was well; for them.

For me, the problems seems to be with phone calls only. Apple Music and Podcasts have worked fine.

I've spent hours on this forum and tried several fixes, but the problem remains.

I sent an email to accessibility@apple.com 7 hours ago, but haven't gotten a reply yet.

You should get a reply but it will take some time. I know it is frustrating but hang in there.
