Aviation headsets have notoriously higher impedance than the typical earbuds
that come with Ipods and other consumer audio devices. Might be an impedance
mismatch requiring a matching transformer.

My iPod *does* have an audio compression feature, and it is turned on.
Quite simply, the minimum audio signal required to power up the Muse is
higher than I would like it to be.

Your headset may have a dip switch that's factory set to mono-out a
stereo
input - like the Bose headset. Try the other setting. Or it may be wired
in
mono. Try it on a stereo source at home.

No switch on my headsets, they're good ol' mono DC's. Knowing that the
majority of aviation headsets are mono, PSE incorporated a mini switch
inside the Muse, to provide either stereo or mono output. The position
of said switch has no discernable effect on the music I hear in my
headsets.
