The headline feature of firmware 7E99 is support for 24-bit 48 kHz lossless audio. Unlike compressed formats that sacrifice detail for smaller file sizes, lossless audio preserves every nuance of a recording, delivering sound as the artist intended it in the studio. Apple describes this upgrade, combined with Personalized Spatial Audio, as offering a “more sonically accurate, uncompressed, and immersive experience.” For casual listeners, this means richer, clearer soundscapes; for professionals, it’s a game-changer for critical listening on the go.
The update also introduces ultra-low latency audio, a boon for music creators and gamers alike. Latency—the delay between a sound’s source and its playback—can disrupt workflows or gameplay. With this improvement, the USB-C AirPods Max now sync sound precisely when connected via a USB-C cable to a Mac running Logic Pro or similar software. This makes them a viable tool for mixing tracks with head-tracked Personalized Spatial Audio, streamlining production without the need for specialized studio gear.
How to Get the Update
Apple keeps firmware updates straightforward but hands-off. To install 7E99, users simply need to place their AirPods Max within Bluetooth range of an iPhone, iPad, or Mac connected to Wi-Fi, then plug them in to charge. The update process can take up to 30 minutes and occurs automatically—no manual prompts required. To confirm the firmware version, users can check Settings > Bluetooth on their device and tap the info button next to their AirPods Max once connected.
While Apple doesn’t provide detailed release notes for firmware updates, the focus here is clear: enhancing audio fidelity and performance. The update requires iOS 18.4, iPadOS 18.4, or macOS Sequoia 15.4, ensuring compatibility across Apple’s ecosystem.
Why It Matters
This update breathes new life into the USB-C AirPods Max, originally launched as a refresh to the Lightning model. While the hardware remains unchanged—save for the port swap—the firmware unlocks capabilities that align with Apple’s push toward high-fidelity audio across its product lineup. It’s a strategic move to keep the AirPods Max relevant amid whispers of a potential second-generation model, rumored for late 2025. For now, existing owners get a free upgrade that enhances value without needing to buy new hardware.
For music creators, the ability to mix Spatial Audio with head tracking directly through the AirPods Max is a standout perk. Pairing this with a Mac and a USB-C cable simplifies workflows, reducing reliance on bulkier studio headphones. For everyday users, lossless audio elevates streaming from services like Apple Music, which already supports the format, making the AirPods Max a stronger contender against rivals like Sony’s WH-1000XM5 or Bose’s QuietComfort Ultra.
Looking Ahead
Today’s release underscores Apple’s commitment to refining its audio offerings through software, even as hardware updates remain sparse. With the AirPods Max now supporting lossless and low-latency audio, they’re better positioned for both entertainment and professional use. As of March 31, 2025, this update ensures Apple’s premium headphones stay fresh and impactful, delivering practical benefits to users without the fanfare of a new product launch.
