AirPods have definitely become an unexpectedly popular Apple product.

Currently listed with a shipping estimate of 1-3 business days on the Apple Online Store, Apple is predicted to move around twenty million AirPod units this year—a noteworthy achievement given the supply-demand imbalance up unit recently.

Arthur Liao, an analyst at Fubon Securities, estimated that shipments of AirPods would total around 20 million units this year and could increase to around 30 million units in 2018.

Inventec officials today hinted at a future HomePod with 3D-sensing features, including facial and image recognition based on iPhone X’s Face ID technology.
