Apple Releases Developer Beta Firmware 8B5034f for AirPods Pro 2, Pro 3, and AirPods 4

The test build is limited to registered developers who opt in through the AirPods Beta Updates setting introduced with iOS 26.

Overview

  • The new firmware carries build 8B5034f, replacing earlier AirPods betas such as 8A5308b.
  • Apple has not provided release notes, so the specific changes or fixes in this build remain undisclosed.
  • Access requires enrolling via the AirPods Beta Updates toggle in iOS 26 or macOS Tahoe, with installation triggered when the earbuds are in their case, the case is powered, and the paired device is nearby.
  • Availability targets H2-equipped models, with AppleInsider reporting that AirPods Max and other non‑H2 devices are not included.
  • The release follows Wednesday’s public rollout of iOS 26.3 and continues developer testing alongside iOS 26 features like camera controls, improved CarPlay hand‑off, and H2‑powered voice isolation.
