Apple has released new public beta firmware for the AirPods Pro 2, AirPods Pro 3, and AirPods 4, . The update, build number 8B5034f, was initially provided to developers last week and is now available to public beta testers.
This firmware release arrives as Apple continues testing iOS 26.4, suggesting a potential connection between the two updates. The new AirPods firmware may include features and optimizations designed to work in conjunction with the functionalities being developed for iOS 26.4.
Apple introduced a streamlined beta firmware update process with the release of iOS 26, iPadOS 26, and macOS Tahoe. These operating systems now include a dedicated beta firmware update installation option within the AirPods settings interface. This simplifies the process for developers and public beta testers to enable and receive beta downloads, eliminating the need for more complex manual procedures.
The availability of this beta firmware is currently limited to those enrolled in Apple’s developer program or the public beta testing program. Unlike previous updates, there is no manual trigger to initiate the installation. Users must ensure their AirPods are configured to receive updates through the official Apple settings, after which the firmware will install automatically in the background.
Currently, AirPods Pro 3 run build 8B34, AirPods Pro 2 are on 8B28, and AirPods 4 utilize build 8B21 in the latest public release. This new beta firmware, 8B5034f, represents an incremental update for all three models, indicating ongoing refinement and testing of new features.
The timing of this release coincides with reports of an upcoming “special Apple Experience” event scheduled for in New York, London, and Shanghai. While the nature of this event remains undisclosed, it suggests Apple is preparing to showcase new products or initiatives in the near future. Bloomberg reports that Apple plans to release an iPhone 17e and a new iPad Air with an M4 chip in the coming weeks, potentially further aligning with the timing of these software updates.
Apple is also reportedly working on a new “Sales Coach” app, rebranded from the existing “SEED” app, aimed at providing sales tips and training resources to Apple Store and Apple Authorized Reseller employees. This internal tool highlights Apple’s continued investment in its retail workforce and customer experience.
Looking further ahead, analysts are beginning to speculate on features for the iPhone 18 Pro models, including a smaller Dynamic Island and potential new color options. While these details are still several months away from realization, they offer a glimpse into Apple’s ongoing innovation pipeline. Rumors also suggest Apple is planning a series of new home products for 2026, expanding its presence in the smart home market, though more ambitious robotics projects are anticipated for 2027.
The release of beta firmware is a crucial step in Apple’s development process, allowing for real-world testing and feedback before wider public release. While the specific changes included in build 8B5034f haven’t been detailed, the update underscores Apple’s commitment to continuously improving the performance, stability, and features of its AirPods lineup. For users participating in the beta program, this update provides an opportunity to experience upcoming enhancements and contribute to the refinement of Apple’s audio products.
