Headphones

Headphones are a pair of miniature loudspeaker drivers that are placed on or over the user’s head over their ears. They are electroacoustic transducers, which translate an electrical signal into a tone. In comparison to a loudspeaker, which releases sound through the open air for those around to hear, headphones enable a single person to listen to an audio source privately. Headphones are often referred to as earspeakers, earphones, or cans.
