Apple's iOS 18.4 Update Elevates AirPods Max with Lossless Audio, Low Latency USB-C Support
March 24, 2025
Despite the positive changes, concerns remain regarding battery life and the necessity for wireless lossless audio support through Bluetooth, Wi-Fi, or UWB.
Users switching from wireless to wired mode can expect a noticeable upgrade in sound quality, especially for gaming or critical listening.
Apple has committed to consistently updating AirPods with new features through firmware updates, following enhancements like hearing health features introduced in late 2024.
However, the AirPods Max have been criticized as confusing and overpriced, with consumers able to find similar quality headphones at much lower prices.
There is still uncertainty regarding whether the original Lightning-equipped AirPods Max will receive lossless audio support or if an upgraded version will be produced in the future.
For gaming enthusiasts, the cable connection is recommended for the lowest latency, enhancing the experience with popular titles like Resident Evil 3 and Assassin's Creed Shadows.
In other news, the development of a rumored plastic Apple Watch SE has reportedly faced serious challenges due to two unspecified key reasons.
To facilitate these improvements, Apple has introduced a new $39 cable that allows playback of full 24-bit 48kHz audio, enhancing sound quality for both casual listeners and audio professionals.
While these new features primarily cater to audiophiles and music creators, the original AirPods Max model remains a solid choice for general use.
Apple's upcoming iOS 18.4 update will significantly enhance the AirPods Max by adding support for lossless audio and ultra-low latency audio over USB-C.
This low latency feature is particularly beneficial for music professionals, enabling accurate monitoring and mixing, including personalized Spatial Audio mixes with head tracking.
Lossless audio provides higher quality sound by delivering audio straight from production, as opposed to the compressed versions commonly found in most audio files.
