There are also newer planes that have the dual jacks but both are standard 3.5 mm stereo jacks, but they are backwards compatible with dual jack headphones.

Wait, so you can plug a 3.5mm headset into either port, and you'll get your normal stereo sound from it?

Yup, I think it also has the perk of allowing two people to watch the same show/movie.

Oh, that's a good point.

More likely you're only picking up left or right audio from one plug or the other
