> Big productions tend to mix assuming you'll play on speakers (where it's fine to have something playing on just one channel/speaker, since both your ears will hear it), but when it mixes down to stereo and you listen on headphones, it's soooo common for them to pan something 100% to one channel when the source is supposed to be on that side.

I find this genuinely baffling; I lived for nearly a decade as a bachelor in a basement apartment where I had a big TV setup, but out of respect for my upstairs landlord listened to nearly everything on wireless stereo headphones, and I can’t recall ever experiencing this.

Me neither, I also only use my headphones. I've only had to use mono mode on amateur youtube videos where one of the audio channels is just missing. It has never been an issue on big productions.

Perhaps they're using a weird media player?
