Abstract: Embodiments of the present invention relate to an earphone that allows for individual adjustment of different audio levels produced out of a first and second speaker to compensate for hearing impairment in one or both ears. The earphone may include a jack plug that is configured for insertion into an audio source that has a first volume control for setting the audio volume level produced by the first speaker. The earphone may also include a second volume control having an inlet and an outlet the inlet being operably connected to the jack plug. The second volume control may be configured to adjust the audio volume level produced by the second speaker. The maximum audio volume level of the second volume control may be approximately the same as the audio volume level set by the first volume control. The minimum audio volume of the second volume control may be inaudible.
