They're not like normal earphones, are they. They're tubes with earpieces on the end. How do they work?

Banana? I can just imagine that! 
This is absoutely correct; the headphones consisting of tubes were linked to speakers in the arms of the seat. They work in the same way as a doctor's stethoscope. Interestingly the ear-pieces that TV presenters wear use the same system. The "speaker" is hidden at the back of your neck or down your shirt. The cirly bit you plug into your ear is just a tube from the speaker to the ear-piece. Similarly this is (in theory) so you can have have a sterile earpiece for whoever uses the system. It never works like that though. You always end up with something grubby that's been in about 5000 grotty ears...
