[CQ-Contest] Mixer

[Joe]

Does anyone have some design to home brew a multiple headphone ummm 
Mixer? Ya know plug into a headphone jack and be able to have multiple 
headphones plugged in.

I'm thinking say two to three or so headphone jacks, and a final output 
for a speaker, and  able to have all independent volume controls. and 
keep the various impedances as needed.

Anyone have a good home brew design?
