Okay so, AirPods come is universal size, are not built to cancel noise but have the H1 chip, Hey Siri is always on, on them. They are not sweat & water resistant, but the battery life is up to 5 and up to 24 hours upon charging one time and with the charging case respectively. Oh, and you also get a wireless charging case or a standard charging case as well. And if you like, you can also have your AirPods engraved for yourself or for your loved ones.
