A free update to Apple's AirPods Pro 2 earbuds allows consumers to take a hearing test and add an over-the-counter hearing aid function. Here's how it works.

Apple Watches ping you when it’s time to wear hearing protection. And now, in many countries, the AirPods Pro 2 earbuds can function as over-the-counter hearing aids.

What’s more, once the hearing aid is set up on AirPods Pro 2, that hearing profile is embedded on the earbuds and you’ll be able to use it without having your iPhone nearby.
