Overview
- Apple released firmware version 8B39 for AirPods Pro 3, AirPods Pro 2, and AirPods 4 on Tuesday, replacing builds 8B34, 8B28, and 8B21.
- The earbuds update arrived alongside iOS 26.4, iPadOS 26.4, and macOS 26.4 in a coordinated software push.
- Apple’s notes cite only bug fixes and other improvements, and there are no listed new features for these models yet.
- The firmware installs in the background when the earbuds are in a closed charging case near a paired iPhone, iPad, or Mac on Wi‑Fi with the case on power, and the process can take about 30 minutes.
- 9to5Mac links 8B39 to the AirPods Max 2 feature requirement for the “latest AirPods firmware,” while other outlets report the release without confirming that tie.
