I wonder if the real difference is that everyone has earbuds versus playing through a speaker

We had earbuds in in early 2000s too, just not the wireless kind.

An important part of my observation is that everyone is using them, not just that they are available

And Bluetooth still doesn't have a good "headphone splitter" function to plug in 2 or more sets of headphones, does it?
