There is a software glitch affecting the Lighting EarPods that ship with the iPhone 7 and iPhone 7 Plus. Some users have discovered that the volume control dongle stops working after leaving their EarPods plugged into the Lightning port of their iPhone 7 or iPhone 7 Plus. The bug stops users from adjusting the volume of their music, and does not allow them to access Siri or answer calls while wearing their EarPods.
