Headphones (or head-phones within the youth of telephony and radio) traditionally ask a pair of small loudspeaker drivers worn on or round the head over a user’s ears. they’re electroacoustic transducers, which convert an electrical signal to a corresponding sound. Headphones let one user hear an audio source privately, in contrast to a loudspeaker, which emits sound into the outdoors for anyone nearby to listen to . Headphones also are referred to as earspeakers, earphones or, colloquially, cans.Circumaural (‘around the ear’) and supra-aural (‘over the ear’) headphones use a band over the highest of the top to carry the speakers in situ . Another type, referred to as earbuds or earpieces contains individual units that plug into the user’s auditory meatus . a 3rd type are bone conduction headphones, which usually wrap round the back of the top and rest ahead of the auditory meatus , leaving the auditory meatus open. within the context of telecommunication, a headset may be a combination of headphone and microphone.
