Okey dokey, time for a lesson in electronics nomenclature.

The thingie on the end of the headphone wire is a PLUG. The thingie that
the plug plugs into is a JACK.

A mono plug has two conductors, the TIP and the SLEEVE. A stereo plug has
three conductors, the tip, the RING, and the sleeve.

A mono jack will have 3 conductors as stated above. A stereo jack will have
4 conductors.

A jack will typically be used for the source of a signal. A plug will
typically be used for the sink of a signal.
