According to MacRumors, Apple analyst Ming-Chi Kou is expecting Apple to add a second supplier for the popular AirPods Pro.

The AirPods Pro were released on October 30 and represent a significant upgrade from the original AirPods. The earbuds add active noise cancellation, a transparency mode to let outside noise in, a charging case that can be charged wirelessly and more. AirProds Pro have received almost universally good reviews and Apple has struggled to keep up with demand.

MacRumors reports that “Kuo expects Chinese company Goertek to begin assembly of AirPods Pro in the first half of the year. The addition of a second supplier alongside Luxshare Precision should help improve supply of the popular earphones, which continue to face multi-week shipping estimates on Apple.com.”

The popular earbuds are proof that innovation and cult-like followings can be achieved with even the smallest devices.
