Audio balance

Have you checked the balance control in Settings/Accessibility/Audio/Visual? There has been no reported software issue that can cause this. Are these Bluetooth or wired headphones?

"Audio balance: All of a sudden both my iPhone and iPad have lost audio balance . I only get the right side to play . Is this an Apple problem? Several different headphones have been used."

Perhaps it's a Bug Going Around?:
