Apple's AirPods Pro will reportedly gain a new 'hearing aid mode' with iOS 18. The device already offers a Conversation Boost feature, but Apple has not advertised it as a hearing aid device as that requires FDA regulatory approval. https://www.macrumors.com/2024/03/11/airpods-pro-to-gain-hearing-aid-mode-ios-18/
@estherschindler My MIL already uses them for a hearing aid. At least I think so, they look like AirPods.
