What you need to know

  • Apple has released a new firmware update for the new 3rd generation AirPods and AirPods Pro.
  • Firmware 4A402 and 4B66 should bring performance improvements and bug fixes.

The 3rd generation AirPods and AirPods Pro have both received a firmware update.

As reported by MacRumors, Apple has released a new firmware update for both of Apple's new earbuds and its now longstanding pro earbuds. The 3rd generation AirPods now run firmware version 4B66 and the AirPods Pro now run firmware version 4A402.

Apple today released a new 4A402 firmware update for the AirPods Pro, which is up from the prior 4A400 firmware that was released back in October. Apple has also updated the AirPods 3 firmware to 4B66, up from the 4B61 that was previously available.

Apple does not let us know what the purpose of a firmware update is. While they typically do not bring any notable features to the AirPods lineup, they usually bring some performance improvements and bug fixes.

If you are trying to manually update the firmware in your AirPods, you're in for an odd process. Apple updates AirPods firmware in the background, so there is no way to tap a button and manually initiate the update. However, the update typically occurs when your AirPods and iPhone are charging together, so you try to do that to potentially initiate the update.
