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.

Now that iOS 18.1 is available to the masses, Apple’s new hearing aid feature is ready for use. The tool is one of three hearing health items the company announced alongside the iPhone 16 in September.

For now, the hearing aid feature is only available with the AirPods Pro 2 model. Users will need an iPhone or iPad to set it up. The feature setup starts with built-in hearing loss tests to determine whether or not users have hearing loss. If they do, they can then set up their own customized amplification levels.
