The AirPods 2nd generation are the most recent member of the AirPods family. They have a few new features and advantages that make them superior to the original AirPods. One of these features is the inclusion of a wireless charging case.
This means you can simply place your AirPods in the charging case and they will begin charging without needing to be plugged in. They also have an upgraded chip called H1, which makes them faster and more efficient than the original AirPods.
