Stoppers
Today's world is full of different sounds and noises.
That's why I used the ambiguous title of "stoppers" in which one can
imagine traditional wine cork stoppers as well as ear headphones
from MP3.
So I combined these two meanings and created my headphones that
look like corks from wine, After that it's up to you if you would like to
listen the sound of silence, or some music of your taste.
