The AirPods Wireless Bluetooth Earphones from Apple use optical sensors and a motion accelerometer to detect when they're in your ears. They instantly turn on and connect to your iPhone, Apple Watch, iPad, or Mac computer and can be used to listen to music, answer calls, or talk to Siri on your device. Additionally, they deliver 5 hours of listening time on a single charge, and they're made to keep up with you, thanks to a charging case that holds multiple additional charges for more than 24 hours of listening time. Just 15 minutes in the case gives you 3 hours of listening time.
