Apple has released a new beta firmware build for five AirPods models, giving developers access to version 9B5043a. The update is available for AirPods Pro 2, AirPods Pro 3, AirPods 4, AirPods 5, and AirPods Max 2.

Apple has not disclosed what the firmware changes. The company does not provide release notes for AirPods beta firmware, so the update’s purpose and any changes to audio performance, connectivity, or features are currently unknown.

Which AirPods models are included

The new beta applies to the following models:

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

The release is aimed at developers rather than general users. Beta firmware can introduce changes that have not been fully tested, making it less suitable for people who rely on their AirPods for everyday use.

How to enable AirPods beta updates

Users with an eligible pair of AirPods can find the beta firmware setting when the earbuds or headphones are connected to an iPhone, iPad, or Mac running iOS 26, iPadOS 26, or macOS 26 or later.

To access the feature, users can open the AirPods settings interface on the connected Apple device and turn on beta updates. Once enabled, the AirPods will be eligible to receive available beta firmware releases.

AirPods firmware installation takes time

AirPods firmware updates do not install through a dedicated software update button. Instead, Apple devices download and apply the firmware while the AirPods are connected and charging.

Because of that process, installation may take several hours. Keeping the AirPods connected to a compatible iPhone, iPad, or Mac and connected to power gives the update an opportunity to complete.

The absence of release notes means users will need to wait for further information or test the firmware themselves to determine what has changed. Apple has not announced specific improvements or fixes associated with build 9B5043a.
