MUNDANE MYSTERIES: Why are they called Headphones?

I wear them every single day when I’m on the radio and still didn’t know why they were originally called headphones.

Back when they were first invented the primary use for the product was telephone operators to have their hands free while they were on the phone. Hence the “head” and “phone” in the name. Then years later once people starting mainly using them for listening to music and audio they just keep the name. I feel like they should’ve called them “ear speakers” at that point right? Either way, that’s they they are called headphones.

Mystery solved.
