Apple boasts that AirPods are "magical" and "effortless" thanks to one-tap setup, which allows them to almost instantly connect to your iPhone, Apple Watch, and other Apple products as soon as you pop them into your ears. They pause when you take them out of your ears. All said, they're packed with technology like Apple's new low-power W1 chip, antennas, accelerometers, beam-forming microphones, and other sensors. For $159, they'd better be magical in terms of sound quality and user experience.
As for battery life, here's what Apple says you'll get: five hours of listening on one charge, with additional charges available via the AirPods' charging case totaling more than 24 hours of listening time. That's right, folks: you'll no longer have to deal with annoying and inconvenient headphone wires, but you'll have to carry around a charging case. ¯\_(ツ)_/¯
