Apple has released a new beta firmware update for several AirPods models. Firmware build 9B5042a is now rolling out to developers and public beta testers who have opted into AirPods beta updates.

The release covers the AirPods Pro 2, AirPods Pro 3, AirPods 4, AirPods 5, and AirPods Max 2. Apple has not provided release notes for the update, so it is not clear whether the firmware contains bug fixes, performance changes, or other improvements.

Which AirPods models are included?

The beta firmware is available for five product lines:

  • AirPods Pro 2
  • AirPods Pro 3
  • AirPods 4
  • AirPods 5
  • AirPods Max 2

Because Apple does not publish notes for AirPods beta firmware releases, testers will need to evaluate the update themselves. The company has not identified any specific new features or changes associated with build 9B5042a.

How to enable AirPods beta updates

Apple provides a beta firmware setting when compatible AirPods are connected to an iPhone, iPad, or Mac running iOS 26, iPadOS 26, or macOS 26 or later. The option is available in the AirPods settings interface.

Users who want to test the firmware can turn on beta updates from that menu. The setting is intended for developers and public beta testers, meaning it is separate from the standard firmware update process used by most AirPods owners.

How AirPods firmware updates install

After beta updates are enabled, the AirPods must be connected to a compatible Apple device. The earbuds or headphones also need to be connected to power before the firmware can download and install.

The process may take several hours. Unlike iPhone, iPad, and Mac software updates, AirPods do not include a dedicated button that lets users manually start a firmware installation. Keeping the AirPods connected to the Apple device and plugged in gives the update an opportunity to complete.

Apple has not said when the firmware will move beyond beta testing or whether build 9B5042a will introduce changes visible to users. For now, the release is primarily relevant to testers who want to try pre-release AirPods software and provide feedback through Apple's beta programs.
