Apple on Monday released new firmware for its USB-C AirPods Max headphones. The new firmware has a build number of 7E99, up from the prior 7A291 firmware.
When paired with a device running iOS 18.4, iPadOS 18.4, or macOS Sequoia 15.4., the new firmware brings lossless audio and ultra-low latency audio to the USB-C version of the AirPods Max headphones. The USB-C AirPods Max support 24-bit 48 kHz lossless audio. Apple says lossless audio and Personalized Spatial Audio offer a “more sonically accurate, uncompressed, and immersive experience.”
With lossless audio and ultra-low latency audio support, music creators are able to use the AirPods Max to create and mix in Personalized Spatial Audio with head tracking, with just a USB-C cable and a Mac with Logic Pro or other music creation software.
While Apple doesn’t offer a way to manually upgrade AirPods firmware, but it is generally installed over-the-air when the AirPods are in a charging case and connected via Bluetooth to an iOS device or Mac.
If your AirPods Max are connected them to a power source, and are paired to an iPhone or iPad, they should update after a short period of time.
