Headphones date from the beginnings of the history of the telephone and the radio. The weak electrical signals of the early instruments were enough to operate only headphones audibly.

Another advantage of headphones over conventional speakers is that the listener experiences total stereo-separation with no mixing of the left and right channels, helping them pinpoint the 'location' of sounds with much greater accuracy. This is of special relevance to videogames that use 3D positional audio, allowing players to better judge the position of an offscreen sound (such as the footsteps of an opponent).

Headphones generally use earphone inductin earphone aid a 3.5 mm "mini pin" jack.

The musical signal is passed through the plates and depending belkin white audio cable rca mini earphone jack upon the signal, the membrane is drawn towards one of the plates forcing air through the perforations. This continuous movement earphone tips of the membrane generates the soundwave. Examples of electrostatic headphones are the Stax SR-007 Omega II, and the Sennheiser HE90 "Orpheus".
