Yuck! As a retired recording studio engineer, CBS Records, having the
same signal out of phase by 180 degrees to one ear, is much like
sticking and ice pick in ones ears.
Most systems will have a variable phase shift depending on frequency,
usually not to exceed 30 degrees. In this case, the leading phase
signal will appear from that direction. In others, bandpass filtering
moves the higher frequency to one side and the lower to the other. From
an audio perspective, this still sounds like "fake stereo". It is
just messed up monaural. There's lots of that today.
The K3S has the AFX function that does an excellent job of signal
spatialization and sounds quite nice on SSB signals.

The K3 (and I think the KX3 and K4) has a simulated stereo function
which allows you delay the audio to one channel slightly, which makes
signals seem to stand out from the noise. I believe that the radios
newer than the K3 also have the ability to create stereo separation by
pitch, which helps in picking out CW signals in QRM.
My question is: is there some kind of device that you can get that will
take the monaural audio from a non-Elecraft radio or a K2 and produce
similar effects?

Some of the various Heil headphones, including the one on the Elecraft site,
have a switch that passively selects between mono and simulated stereo by
changing the phase between the two sides. It basically seems to widen the
perceived space of the sound source, possibly helpful.

Any*Stereo* headphones can accomplish the same thing by simply adding
a DPDT switch wired to reverse the connections (invert polarity) to
one of the two ears.
