AirPods Now Estimated to Ship in 6 Weeks
Apple said AirPods will be shipping in limited quantities at launch, so it is unsurprising that shipping estimates have quickly slipped from 2 weeks to 4 weeks to 6 weeks around the world. The delay means customers who have yet to place an order will likely not receive their AirPods until 2017.
However, those who missed out still have a chance, as Apple said AirPods will be available for purchase at Apple Stores, authorized resellers, and select carriers next week. Apple noted stores will receive "regular AirPods shipments," and customers would be wise to call their local store ahead of time to confirm stock.
AirPods are Apple's all-new $159 wireless earphones. The cord-free earphones instantly turn on and connect to your iPhone, Apple Watch, iPad, or Mac when taken out of their charging case. Likewise, audio automatically plays as soon as you put them in your ears and pauses when you take them out.
AirPods, driven by Apple's custom W1 chip for one-tap setup, deliver up to 5 hours of listening time on one charge, and a 15-minute fast charge provides up to 3 hours of listening time. The accompanying charging case holds multiple additional charges for more than 24 hours of listening time.
AirPods use optical sensors and a motion accelerometer to detect when they are in your ears. Doubling tapping an earpiece invokes Siri, which can be used to adjust the volume, change the song, make a call, or get directions. An accelerometer works with beamforming microphones to filter out background noise.
