The AirPods 3 come with new features such as spatial audio (or surround sound) and a water-resistant MagSafe charging case. The AirPods 3 stems are shorter than the AirPods 2 and look more like the AirPods Pro. The AirPods 3 also offer a longer listening time with the charging case: up to 30 hours versus 24 hours on the AirPods 2.
