After iPhone 7 and iPhone 7 Plus owners started taking to Twitter to complain that the volume controls on their new Lightning EarPods stopped working, Apple said it is working on a fix, Business Insider reports. Some users have noticed that after a while of being plugged into the Lightning port, the EarPods keep playing music but the volume control dongle stops working, preventing them from using it to change the volume, answer calls or activate Siri.
