Apple's highly anticipated firmware update for the USB-C version of the AirPods Max, which was set to unlock lossless and ultra-low latency audio over a wired connection, has been delayed due to a bug in iOS 18.4. Despite the firmware being live on Apple's servers, users are unable to download or install it on their AirPods Max units, leaving them waiting for the update to become available.
The update, when it does arrive, will bring support for 24-bit, 48kHz lossless audio when used with Apple’s USB-C to 3.5mm audio cable, making it the first time AirPods Max will support uncompressed audio over a wired connection. In addition, the firmware will enable ultra-low latency playback, enhancing the experience for professionals working in audio-related apps.
Developer Aaron Peris was the first to notice the issue, where the firmware is ready but cannot be pushed to the headphones due to the iOS bug. The problem seems to only affect the new USB-C model, with older Lightning-based AirPods Max not receiving the update. Apple has stated that these new features will only be available for the USB-C version.
