Apple's AirPods Pro 2 now have a “hearing aid feature”: a hearing test and the ability to amplify sound for mild or moderate hearing loss, with a free software update.

Experts say that addressing hearing deficits is beneficial for our health, and it has become easier in recent years.

The hearing aid feature is available with AirPods Pro 2 models, and requires an iPhone or iPad to set it up. It starts with built-in tests that will help users determine if they have hearing loss, set up the feature if they do, and set personalized amplification levels.
