Apple did not treat AirPods Max 2 as an afterthought in the iOS 27 cycle; it pulled the over-ear headphones into beta firmware testing just after iOS 27 beta 2 and macOS 27 beta 2 landed.
That is the real signal beneath the firmware note. Apple is widening the test surface around AirPods features before the next OS release, with AirPods Max 2 getting its first beta firmware and other supported models receiving second beta builds, according to 9to5Mac .
AirPods Max 2 enters the iOS 27 test cycle later than the rest
The expectation was simple: Apple had already said AirPods Max 2 would “soon” join AirPods 4, AirPods Pro 3, and AirPods Pro 2 in supporting beta firmware updates after the first iOS 27 and macOS 27 betas. The reality arrived with the second OS betas.
Apple is now rolling out the first-ever beta firmware build for AirPods Max 2, while releasing fresh beta firmware for:
- AirPods Pro 2
- AirPods Pro 2 (USB-C)
- AirPods 4
- AirPods 4 with ANC
- AirPods Pro 3
- AirPods Max 2
All supported models are on version 9.0.304, build 9A5304b.
The split matters. AirPods Max 2 is not just receiving a normal public maintenance update. It is entering Apple’s pre-release firmware lane during the same cycle as iOS 27 and macOS 27. MLXIO analysis: that makes this less about one headphone model and more about Apple tightening how AirPods firmware, iPhone software, and Mac software move together.
For related context on the beta switch itself, see our earlier coverage of how iOS 27 hides AirPods’ best upgrade behind a beta switch and why iOS 27 fixes the AirPods settings mess users hate most.
The supported-device list shows Apple’s current AirPods testing boundary
The rollout draws a clear line around which AirPods are inside this beta cycle. The current beta includes newer AirPods Pro, AirPods 4, and AirPods Max 2 models. Older models are not listed in the 9to5Mac report as part of this beta push.
That boundary matters because Apple announced upcoming AirPods features at WWDC26, including custom EQ and Apple GymKit syncing. MacRumors also reports that iOS 27, iPadOS 27, and macOS Golden Gate add a new AirPods interface, custom EQ support, and compatibility with the new Siri AI.
The before-and-after is stark:
- Before: AirPods firmware mostly appeared as quiet background updates, with users checking version numbers after the fact.
- After: Eligible users can opt into beta firmware from AirPods settings on an iPhone, iPad, or Mac running the required beta OS.
- Before: AirPods updates were mostly invisible unless something broke or a feature appeared.
- After: AirPods firmware is visibly tied to Apple’s annual OS beta cycle.
Apple’s own enrollment path is also more explicit now. On iOS 27 beta or macOS 27 beta, users connect AirPods, open Bluetooth settings, tap the information button, and enable “AirPods Beta Updates.”
Apple notes that once users turn on the “AirPods Beta Updates” switch, “firmware updates will be installed when your AirPods are in their charging case and nearby” the paired iPhone or Mac.
That sounds easy. The risk sits underneath.
Version 9A5304b is unified, but the public firmware baseline is not
The clean number in this release is 9A5304b. Every supported model in the beta gets the same build. But Apple’s public firmware versions remain fragmented by product.
Apple’s support page lists current public firmware versions including 8E258 for AirPods Max 2, 8B41 for AirPods Pro 3, 8B41 for both versions of AirPods Pro 2, and 8B39 for AirPods 4 and AirPods 4 with Active Noise Cancellation.
That creates the real technical tension:
| Device group | Public firmware listed by Apple | New beta build |
|---|---|---|
| AirPods Max 2 | 8E258 | 9A5304b |
| AirPods Pro 3 | 8B41 | 9A5304b |
| AirPods Pro 2 | 8B41 | 9A5304b |
| AirPods 4 / AirPods 4 with ANC | 8B39 | 9A5304b |
MLXIO analysis: the unified beta build suggests Apple wants one firmware branch tested across several current AirPods lines. That does not mean every device gets the same features, and Apple has not published release notes for 9A5304b detailing model-by-model changes. It means the test cycle now spans multiple product tiers at once.
That is useful for developers. It is also a warning for casual users.
The beta switch gives developers access, not a safe undo button
The biggest practical change is not the build number. It is the fact that AirPods firmware beta enrollment is now exposed through settings on supported beta OS releases.
Per Apple’s update model, AirPods firmware installs automatically when the devices are charging and near a paired device. Apple’s public support page says standard firmware updates are delivered while AirPods are charging and in Bluetooth range of an iPhone, iPad, or Mac connected to Wi-Fi. AirPods Max updates require the headphones to be connected by charging cable and kept in Bluetooth range for at least 30 minutes.
iClarified reports one key caveat for this beta path: once beta software is applied, the devices cannot be rolled back to an earlier release and remain on the beta track until a newer public version becomes available.
That changes the user calculus.
For developers, early firmware access can help expose whether iOS 27-era AirPods behavior affects audio routing, media playback, accessibility flows, or app behavior that depends on connected headphones. That is analysis, not a claim about what Apple specifically changed in 9A5304b.
For enthusiasts, the attraction is obvious: AirPods Max 2 owners can test Apple’s first pre-release firmware for the new headphones. But the tradeoff is also obvious. Firmware is not as easy to escape as an app beta.
For mainstream users, the safer path is still public firmware. Audio bugs do not stay abstract. They hit calls, meetings, workouts, commuting, and device switching.
AirPods firmware is becoming part of the OS release, not a side update
AirPods used to feel peripheral to Apple’s software calendar. This release argues the opposite. iOS 27 beta 2, macOS 27 beta 2, and AirPods firmware 9A5304b are moving in the same window.
Apple has not said what changed inside this build. That limits the analysis. The confirmed facts are narrower: first beta firmware for AirPods Max 2, second beta builds for other supported AirPods models, shared build 9A5304b, and upcoming AirPods features including custom EQ and Apple GymKit syncing.
The next useful signal will not be the mere existence of another beta. It will be whether Apple publishes clearer release notes, expands model support, or ties specific iOS 27 AirPods features to specific firmware builds. If later betas keep arriving alongside iOS 27 and macOS 27 updates, that would strengthen the read that AirPods firmware is now a first-class part of Apple’s OS testing cycle. If the builds slow or remain undocumented, this may stay a developer-focused plumbing change rather than a visible shift for most AirPods users.
Key Takeaways
- AirPods Max 2 is now part of Apple’s iOS 27 and macOS 27 beta firmware testing cycle.
- All supported AirPods models are aligned on firmware version 9.0.304, build 9A5304b.
- The rollout shows Apple is coordinating AirPods firmware more tightly with iPhone and Mac software releases.
