Reply to comment by epic1107 in eli5: Why do most airlines still use 2-pin audio jacks for the in-flight entertainment systems on their planes? by JJGLC92

I've flown fairly new 777s, A380s and smaller airbuses (a320 maybe?) And they all had double jack thingies.

They were full service international flights though so maybe that's why?

Domestic shorthaul budget flights have been single jack though.

Wasn't in US either, so maybe it's region/airline dependent

My theory is that they can hand out the nice headphones in business/first and they won't be stolen as much. There's nothing else to plug them into.

Economy class gets the cheap thin earbuds on a single jack and they don't bother to gather them back now. They're disposable.
