Apple released a beta firmware update for its AirPods lineup to accompany the iOS 27 developer beta unveiled at WWDC. The new build supports custom EQ and GymKit syncing, features announced for iOS 27. Firmware rolls out automatically for AirPods Pro 3, AirPods Pro 2 and AirPods 4 once users opt in via the iPhone Settings app. This enables developers to fine‑tune audio performance.

Historically, installing AirPods beta firmware required Xcode and a Mac, but Apple simplified the process last year. Now a dedicated “AirPods Beta Updates” toggle lets the update download in the background, reducing friction for developers testing the custom audio profile and GymKit integration. Early adopters should expect typical beta instability, such as occasional dropouts or latency spikes, and may affect battery life briefly.

Because the firmware targets the upcoming iOS 27 release, users who want to experiment with the new EQ presets or sync workouts to Apple GymKit must run the iOS 27 developer beta alongside the AirPods update. Those uncomfortable with beta quirks can wait for the public beta slated for next month, but the streamlined rollout signals Apple’s push to treat wearables like core platform components. It also expands the AirPods ecosystem.
