In July, Apple started giving developers access to a beta version of the AirPods Pro firmware to allow for testing of new features past their release. On the 30th July 2021, Apple released AirPods Pro firmware (4A362b) which went under the radar until 4th August 2021.
According to Apple’s developer site, the new firmware update adds support for Conversation Boost. This was missing from the first beta.
Conversation Boost is an iOS 15 feature that uses beamforming microphones in the AirPods Pro to boost the volume of conversations. This helps those who have hearing difficulties ranging from mild to moderate.
Initial AirPods Pro firmware beta added FaceTime Ambient Noise Reduction and Spacial Audio. These features are also coming in the iOS 15 update along with the Conversation Boost feature.
The only downfall in all of this is that only registered developers are able and allowed to install the new AirPods Pro firmware. The installation process is complicated and requires Xcode – software only available on macOS.
