The word "stereo" has a specific meaning -- an acoustic sound stage 
being picked up by a spaced array of microphones and reproduced through 
a spaced array of loudspeakers. The mass production of this concept has 
been many mics mixed to two channels that are reproduced by two 
loudspeakers, or headphones.

A correct description of what the K3, K3S, and KX3 do is "binaural," and 
the plug is correctly described as a 3-circuit plug.
