Each round AirTag is small and lightweight, features precision-etched polished stainless steel, and is IP67 water- and dust-resistant.² A built-in speaker plays sounds to help locate AirTag, while a removable cover makes it easy for users to replace the battery.³ AirTag features the same magical setup experience as AirPods — just bring AirTag close to iPhone and it will connect. Users can assign AirTag to an item and name it with a default like “Keys” or “Jacket,” or provide a custom name of their choosing.
