Apple appears to be gearing up for future devices supporting Bluetooth 5.2, according to a filing in the Bluetooth SIG product database earlier this month. Among other possibilities, this could serve as proof of future AirPods Pro with LE Audio support.

Apple’s filing refers to a Bluetooth 5.3 host subsystem that is likely intended for future products. However, in reality the filing is probably referring to Bluetooth 5.2, as the Bluetooth versions listed in Apple’s filings in the database are often a higher version number than the version that ends up being supported on a device. , for unclear reasons.

For example, the Beats Studio Buds are listed with Bluetooth 5.3 despite supporting Bluetooth 5.2, according to headphone reviews, while many iPhone and iPad models are listed with Bluetooth 5.1 despite supporting of Bluetooth 5.0.

With all this confusion surrounding version numbers aside, Apple adopting Bluetooth 5.2 would be particularly beneficial for AirPods, as the specification includes support for LE Audio along with several enhancements to wireless audio streaming.

LE Audio is part of the Bluetooth LE low energy standard. According The edgeLE Audio’s benefits for wireless headphones like AirPods could include improved audio quality, longer battery life, the ability to connect more than two pairs of AirPods to a single iPhone, and the ability for each Left and right AirPods to have their own Bluetooth connection to an iPhone to avoid desync during audio playback.

In July, the Bluetooth SIG said it expects the availability of products supporting LE Audio to increase by the end of 2022. Apple is expected to launch the second-generation AirPods Pro by the end of the year, but whether they support Bluetooth 5.2 or LE Audio remains to be seen. It also remains to be seen if Apple would add LE Audio support to the Beats Studio Buds with a firmware update given that these headphones already support Bluetooth 5.2.
