According to new reports, the next-generation pair of AirPods Pro will not feature substantial design changes. Purportedly, Apple will return to its much-loved stem design language, while swapping out IR sensors for skin-detect sensors from the AirPods 3. Apple Lossless support is also expected to make an appearance on the AirPods Pro 2, which Apple is rumoured to launch in the autumn.
