Eli5: Why can’t headphones be used as speakers?

657 views

Large headphones can have drivers that are a similar size to small speakers, and yet at maximum volume they’re never anywhere close to speakers. Why? Is it to protect the user from them being too loud while they’re on? Or is it a difference in driver design?

Their impedance is much higher than speakers of the same size. This causes them to consume less electricity. This is super-important for battery-powered devices.
