There is no difference between the "Plug MP3 player” and the normal plugs in appearance, people will mistake it for a plug if there’s no control panel, it’s just a simple MP3 player in function and control panel is similar to the iPod shuffle, it also has a LED indicator and can be charged when connecting the power supply, surely a very creative design. Focus of the design lies in its unique shape and convenient charging. Designer: Giha Woo.
