AirPods Pro firmware beta one features FaceTime Spatial Audio and Ambient Noise Reduction.
Apple made the announcement that beta firmware for AirPods Pro would be available to developers earlier this year, allowing for certain AirPods Pro software features or changes to be widely tested before they are pushed to the public, but it did not originally give a timeframe for its release.To install the beta firmware, users must have an iPhone running iOS 15 beta software, a Mac running Xcode 13 beta software, and have fully charged their AirPods Pro.
It requires an AirPods Pro configuration profile to be installed on an iPhone, AirPods Pro to be connected to the iPhone, the iPhone to be connected to a Mac running the Xcode 13 beta, iPhone Prerelease Beta Firmware settings to be turned on, AirPods Pro automatic beta software updates to be turned on, and then an on-screen process to be followed.
