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.

Start by putting your AirPods Pro 2 in your ears and then open Settings. Tap on your AirPods (near the top of the Settings page) and look for the Hearing Health section. You’ll see options for Hearing Protection, Hearing Assistance, and Take a Hearing Test. Tap that to get started.
