As posted by Twitter user George (via ShrimpApplePro), he enabled the LC3 codec for the AirPods Max via his beta firmware. The LC3 codec is the low-power and high-quality codec of the future of Bluetooth, coming to headphones soon. The LC3 will be able to transmit at much lower bit rates without degrading the audio quality we currently see with the Bluetooth standard.
In this case, as demonstrated by a Twitter user, the LC3 codec will improve audio calls and make them sound better, but the true potential of this technology will require Bluetooth 5.2 and a new generation of AirPods hardware. While the LC3 codec will improve audio calling, efficiency, and stability for Bluetooth devices, taking full advantage of the standard’s requirements will require Bluetooth 5.2, which AirPods don’t have.
9to5Mac sources have confirmed that the next-gen AirPods Pro, codenamed B698, will feature the next-gen H1 chip, which isappleits own audio processor, it might be able to handle this technology. Additionally, 9to5Mac has found references to support for the LC3 codec and low energy audio support on iOS 16. For LE audio support, it’s worth mentioning that a senior Apple engineer is actively involved in this new standard.
With Bluetooth 5.2 and LC3 support, Apple will be able to get rid of the AirPods out of sync when they are on the user’s ear, and improve battery life with low energy standards while focusing on efficiency and stability.
