Zipup / Earphone


If you are a person who take portable sound device such as cellular phone and MP3P, you may have experienced that you untied the twisted earphone line to listen to music. If you put it in the narrow space such as pocket or bag for a long time, the earphone line is twisted naturally.
This earphone line twisted-situation changes good feeling into annoying when you listen to music.
In order to solve such inconvenience, we came up with an idea which can fix two lines of each earphone using the structure of zipper. When to do not use, you can avoid twisted line by fixing two lines into one line through up & down the slide bar.
