Is this the right way to wire the stereo headphone? (Kindly see attachment)
Secondly, there is whining sound when i am using a headphone (with and without the mic attached). When i touched or moved my hand near the potentiometer, the whining sound became softer or disappeared. Any idea what is the cause for it? (I am testing it on a breadboard)
