Not sure what your definition of normie is, but that's been my experience across a fairly wide spectrum of US society.

When I went to public high school in rural America, pretty much everyone I knew owned some sort of headphone/speaker system, and they would be used at every party / larger gathering where audio was important.

It depends on the context though. Obviously if someone is just sharing something casual like a Youtube video on their phone, they're going to use the built-in speakers.
