Apple has rolled out a fresh test firmware (with the build number 8B5014c), exclusively aimed at developers, for the AirPods Pro 2, AirPods Pro 3, and AirPods 4 wireless earbuds. This particular update is poised to bring in a groundbreaking real-time multilingual translation capability. It will encompass languages like Chinese, Japanese, and Korean, thereby broadening the scope of the earbuds' utility in cross-linguistic communication settings. Simultaneously, with the launch of iOS 26, iPadOS 26, and macOS Tahoe systems, Apple has incorporated an installation access point for test firmware updates within the audio device settings menu. This move streamlines the operational procedure, boosts testing effectiveness, and underscores Apple's unwavering commitment to refining the synergy between software and hardware, as well as fine-tuning user experience details.
