AI summary of the reporting below · Updated · How we work

Apple is rolling out firmware version 9B47 for several models that feature its H2 chip, covering AirPods Pro 2, AirPods Pro 3, AirPods 4, AirPods 5, and AirPods Max 2. The update arrives roughly two months after build 9A348, which debuted in September alongside iOS 27 to introduce GymKit integration and Custom EQ support. [1][2]

Apple has not published release notes explaining what changes in build 9B47, though the update is anticipated to focus on bug fixes and performance improvements. Because AirPods cannot be updated manually, users must wait for background installation by connecting their case to power, keeping the lid closed, and leaving the earbuds within Bluetooth range of a Wi-Fi-connected iPhone, iPad, or Mac for at least 30 minutes.
