All changes in AirPods beta firmware 9A5336b
Apple has not published detailed release notes for build 9A5336b, and no major changes specific to this beta have been discovered yet.
The wider iOS 27 AirPods beta cycle includes the following improvements:
- Updated AirPods settings: iOS 27 introduces a redesigned interface that places supported controls and audio options in a clearer layout.
- More control over Adaptive Audio: Compatible AirPods receive a slider that lets users adjust how strongly Adaptive Audio balances noise cancellation and outside sound.
- Custom EQ options: The new software provides additional controls for adjusting the AirPods sound profile based on personal preferences.
- New Siri features: Supported AirPods work with the latest Siri and Apple Intelligence features available through iOS 27.
- Bug fixes and stability improvements: The beta firmware also prepares supported AirPods for iOS 27 while addressing connection, control, and performance issues found during testing.
Apple is expected to release the finished AirPods firmware alongside iOS 27 next month. Users who rely on their AirPods every day should avoid installing beta firmware because Apple does not provide a simple way to return to the public version.
