Headphones are 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.
What are earphones used for?
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 are also known as earspeakers, earphones or, colloquially, cans.
How do you describe earphones?
Earphones are a small piece of equipment which you wear over or inside your ears so that you can listen to music, the radio, or your phone without anyone else hearing. An earphone is the part of a telephone receiver or other device that you hold up to your ear or put into your ear.
How many types of earphones are there?
There are four different kinds of headphones and earbuds. You can differentiate them through their fitting with the ears: in-ear, on-ear, over-ear, and open-ear headphones.
