[TenTec] Heil headphones

[Jim McDonald]

I remember reading, a long time ago, that the Heils used to be 200 ohms but
they were later changed to be lower impedance.  Heil could confirm that.

When I use my $300 Bose Quiet Comfort 2 headphones after using my ProSet
Plus, I have to reduce the volume LOTS on any radio.  That's with the Bose
in the Hi output position; in the Lo position I need increase the volume.  I
don't know their respective impedances.

FWIW, for 4 years my v1 Orion I/Heil Pro Set (200 ohms) combo has been
100% consistent in my ability to just set AF Gain at 50% and vary RF
Gain till I can just hear the band noise.  This has always given
excellent AF/RF level in all conditions.  This only applies to v1
firmware.
