How about the fact that there are two receivers with various  left ear / 
right ear audio feed options. I don't have an Orion, so I'm only 
guessing on this, but there may also be various options for what (and in 
what proportions) comes out of the speaker. If you just did the simple 
thing that has worked for years, that is put a resistor in series with 
the headphone jack, fed by the same audio PA that feeds the speaker, you 
would have to use two audio PAs (and two speaker outputs), and whatever 
you selected for the speakers would have to be the same for the headphones.
