Usually I have the maximum gain at the output of my PC which is good for my computer speakers, but bad for my headphones. The potentiometer would allow me to passively lower the gain for the headphones while delivering the maximum gain to the speakers. Unfortunately you have to use a DPDT switch because it is a 2-channel stereo signal. Even with the DPDT switch, the grounds are connected together at all times. Thanks for the comment! @jared

An op amp would be nice for boosting signals though. You could also just use a SPDT and leave the grounds connected together at all times. Nice work! I need to make one of these.
