On September 8th, Apple’s official website device technical specifications show that all four iPhone 14 series models and AirPods Pro 2 support Bluetooth 5.3, but it is unclear whether these devices support LE Audio technology.

LE Audio is a low-power audio streaming specification that is supported on devices with Bluetooth 5.2 or higher. LE Audio reportedly brings improved audio quality to AirPods Pro, longer battery life, multi-streaming audio, connecting multiple pairs of AirPods to iPhone at once, and eliminating the need to switch between iPhone and Mac.

It is understood that the report said that neither the press release nor the technical specification page of Apple's iPhone 14 and AirPods Pro mentioned LE Audio and related information, and it has contacted Apple for confirmation. In July, the Bluetooth SIG said that it expects to see increased availability of LE Audio-enabled products by the end of 2022.

Given that the iPhone 14 models and AirPods Pro 2 support Bluetooth 5.3, Apple may enable LE Audio in the future through a software or firmware update if the device does not currently support the LE Audio specification.
