Apple has released a new beta firmware build for AirPods models featuring the H2 chip, including AirPods Pro 3. The update—version 9A5347a—is now available to developers and is expected to deepen support for features launching with iOS 27. Several models are included in this update: AirPods Pro 3, AirPods Pro 2, AirPods 4, and AirPods Max 2. Earlier this month, Apple pushed build 9A5336b, making this the second beta firmware in roughly two weeks.

What this beta brings
While full patch notes haven’t been shared publicly, today’s beta is designed to add support for coming features in iOS 27—some of which are exclusive to the AirPods Pro 3. The firmware lays the groundwork for functionality that didn’t yet ship with the devices, suggesting Apple is preparing more than just minor tweaks.

For users who haven’t yet opted in to beta firmware, the update is accessible through the AirPods settings. If your pair is one of the H2-equipped models, it should offer the 9A5347a build via developer provisioning.

Timing and context
The new firmware comes as Apple gears up for iOS 27’s official launch next month. The timing isn’t coincidental—firmware updates like this often arrive in beta form before a major iOS release, allowing Apple to test features such as enhanced device capabilities and possible surprises at its September event.

In recent years, Apple has used its September events to unveil AirPods-related innovations—past launches include Live Translation for AirPods and expanded Hearing Health features. With this update, those trends might continue. ([9to5mac.com](https://9to5mac.com/2026/08/20/airpods-pro-3-and-more-just-got-new-firmware-release-in-beta/))
Battery or performance tweaks haven’t been confirmed yet; so far, public observation hasn’t turned up major changes beyond compatibility to iOS 27’s new features. Still, the beta signals what’s intended to ship later this fall. ([9to5mac.com](https://9to5mac.com/2026/08/20/airpods-pro-3-and-more-just-got-new-firmware-release-in-beta/))
What to watch
As Apple rolls toward its annual fall launch event, keep an eye on surprises that could appear alongside iOS 27—especially features tightly linked to Pro 3. Early beta feedback may reveal small but significant improvements in sound quality, latency, or battery behavior. If past firmware cycles are any guide, even seemingly minor updates can contain clues about bigger shifts in how Apple handles its audio lineup.
For users on the fence, the beta update provides a preview of Apple’s roadmap—and underscores how much the AirPods experience is still evolving. If you’re using one of the supported H2 models, installing 9A5347a could give you a glimpse into Apple’s next phase of audio enhancements ahead of official release.
