Apple has launched a new developer beta firmware for the AirPods Pro 2 and the recently introduced AirPods 4, continuing to refine the personal audio experience. The update, released on Tuesday, comes with build number 8A5343a, replacing the previous version 8A5324b.
What’s New in the Beta
The latest firmware update is specifically designed for devices running Apple’s upcoming fall software releases, including iOS 26, iPadOS 26, and macOS Tahoe. Some of the key features currently in testing include:
- Camera Controls: Enhanced integration with Apple devices, offering improved control.
- Voice Isolation: Powered by the H2 chip, this feature boosts call clarity in noisy environments.
- CarPlay Hand-off: Smoother transitions between iPhone and car audio when switching between devices.
These additions highlight Apple’s continued efforts to refine the ecosystem across its hardware and software platforms. However, the beta update is limited to the AirPods Pro 2 and AirPods 4 (available in both USB-C and Lightning versions), leaving out other models like the AirPods Max.
How to Install the Beta
Unlike updating an iPhone, installing the beta firmware on AirPods requires a few extra steps:
- Your host device must be running iOS 26, iPadOS 26, or macOS Tahoe.
- Enable Developer Mode by going to Settings > Privacy & Security.
- Navigate to Developer > AirPods Testing and select the Pre-Release Beta Firmware option.
Apple advises caution when installing beta firmware, as it may introduce bugs or cause data loss. It’s recommended that users avoid running the beta on essential devices.
What’s Next
This beta release is part of Apple’s broader fall software update cycle, suggesting that the full rollout could coincide with the public release of iOS 26. For now, developers and early testers can explore the new features, which could significantly enhance the way AirPods work with other Apple devices.
