The left headphone is also wired to be a microphone.  You can actually
yell into the left headphone when recording.  (Though, it would work
better if something a bit more sensitive were connected, like a
microphone.)

You can, actually, just get a 1/8 -> 3/32 stereo adapter from RadioShack.
Then connect a handsfree headphone to it.
