This flight was on the Singapore Airlines Airbus A330-300 (A333) with 172 degree reclining seats.
There is an audio port deep DEEP in the bottom/storage area of the seat, which is quite a nightmare to try to get the headphones into. If you manage to do it, you’ll be rewarded with no audio whatsoever, and also another lesser pain to extract it but still one nonetheless. The actual headphone jacks are near the top of the seat by your ear.
I had the veal, and one seriously huge piece of asparagus. Everything was all pretty tasty.
