Abstract
An exemplary media player system includes a media player and an earphone. The earphone includes a first earpiece, a second earpiece, a primary volume control unit, and a secondary volume control unit. The first earpiece and the second earpiece are configured for receiving first channel audio signals and second channel audio signals respectively, and converting the audio signals to yield audible sounds. The primary volume control unit adjusts the volume levels of the first earpiece and the second earpiece simultaneously. The secondary volume control unit adjusts the volume of sounds outputted from one of the first earpiece and the second earpiece.
