Apple distributes AirPods beta firmware build 9B5043a to developers and testers

Apple has distributed a new beta firmware update for its AirPods lineup, according to MacRumors. The release is available to developers and public beta testers. It affects the AirPods Pro 2, AirPods Pro 3, AirPods 4, AirPods 5, and AirPods Max 2. The build number is 9B5043a. This rollout involves devices connected to specific operating system versions.

Which devices are affected?

The firmware applies to five specific Apple audio products. MacRumors lists the AirPods Pro 2, AirPods Pro 3, AirPods 4, AirPods 5, and AirPods Max 2 as eligible. These are the only models mentioned in the report. Organizations with mixed fleets should verify which models are in use before assuming coverage.

Who can install this update?

The beta is available to both developers and public beta testers. According to MacRumors, users must have an iPhone, iPad, or Mac running iOS 26, iPadOS 26, or macOS 26 or later. The beta option appears in the AirPods settings interface on these host devices. Toggling the setting enables the download.

How does the installation process work?

Installation requires the AirPods to be connected to the host device and connected to power. MacRumors states that users must connect the AirPods to an Apple device and connect them to power. For AirPods Max, 9to5Mac specifies plugging the charging cable into the earphone. MacRumors notes that installation can take a few hours. There is no standalone update interface on the earbuds themselves.

What changes does this firmware include?

Apple has not provided a changelog for this beta release. MacRumors states there is no word on what is included because Apple does not offer notes for AirPods beta releases. This lack of detail is typical for pre-release firmware but complicates risk assessment for operations teams.

Questions to ask your suppliers

Teams should ask whether this firmware version is compatible with existing management profiles. Check if the vendor provides any telemetry regarding the beta's stability or scope. Determine who within your organization is authorized to enable beta toggles on corporate devices. Ensure that asset inventory systems can track firmware states for these audio peripherals. Clarify the process for rolling back to stable firmware if issues arise.

What to do and how to stay safe: Apple

• Audit managed devices to see which hosts are running iOS 26, iPadOS 26, or macOS 26.
• Restrict access to the beta firmware toggle in device configuration profiles.
• Monitor internal channels for reports of connectivity issues or battery drains.
• Wait for official documentation before applying updates to production fleets.
