For the second time in as many weeks, Apple has updated the firmware for AirPods Pro 2 (both USB-C and Lightning variants).

Apple has not yet posted release notes for this firmware update, but will do so at this support page.

This fall, AirPods 2 are expected to get a new “clinical grade” hearing test function as well as the ability to function as over-the-counter hearing aids. Apple received the first-ever FDA authorization for hearing aid software on September 12. There has been some evidence that the latest iOS 18.1 and macOS 15.1 include the code for this feature, but it is not yet activated in the beta. It is quite possible that Apple will enable it with a server-side switch when it is ready, and these frequent AirPods Pro 2 firmware updates may be the result of rigorous internal testing of the feature.

Updating your AirPods firmware

There isn’t a way to force an upgrade to the new firmware; it will automatically install when the AirPods are in their case and charging. It can take hours or even days to get the latest firmware. If you haven’t used your AirPods in a long time, taking them out of their case and using them for a few minutes before putting them back in and on the charger may help speed things up.

To see what firmware version your AirPods are running, you can open the Settings app, select your connected AirPods (near the top), scroll down past all the options to the About section, and look at the Version line. You can also find this information in General > About > [name of your AirPods].
