Double Jack Headphones - Like the ones found on some Aircraft

[Robert]

I was wondering if someone could help me with how the double jack
headphones work?? Why are there two jacks?? Is it one lack for each
headphone output?? Or is one the signal and the other is ground?? Help
on this would be great thank you. I am planning to make an audio
amplifier to take on holidays so I can ramp up the planes signal
because they are so low sometimes.

Ït is probably just one plug for each stereo channel. You can buy an adapter
plug at you local electronic shop and they can probably help you too.

Look at each plug if there is 3 contacts on each ( TIP,RING,SLEVE)
You may have a Quad headphone ( 4 ch )

Hope it helps
