Is it possible to see voltages coming in from a mic or set of headphone plugged into the 3.5 audio jack or can you only hear the audio coming out 


I want to get a voltage from a headphone after i epoxy the coil windings so they dont move or pick up sound

I have tested it (the epoxyed headphones) with a frequency app on my Mac book and it works to an extent.
