Headphone / Antiques of the Present

Synonyms

Earspeaker; earphone

Definition

A pair of small loudspeaker drivers worn on or around the head over a user's ears. They are electroacoustic transducers, which convert an electrical signal to a corresponding sound. Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air for anyone nearby to hear. Headphones use a band over the top of the head to hold the speakers in place.
