How to Enable Mono Audio Output on iPhone

In most cases, stereo audio output is ideal and it makes sense the default iPhone setting is indeed stereo output.  However, there are some scenarios in which it can be advantageous to have mono audio output instead. Good news- this is made possible by the touch of a switch! When Mono Audio is enabled, the left and right channels are combined in a single mono signal played in both channels. The result is you can hear everything in either ear.  This guide will breakdown how to get to that switch in your iPhone and put the power in your hands.
