Left or right? / earphones

Left or right?

Listening to music is a very pleasant thing,but people sometimes would mistake left and right of the earphones."Left or Right" helps to solve this problem by making the sign "R" raised on the right earphone like Braile,while the left remain the same.Users then don't need careful identification of them,but a touch by hand can distinguish them quickly and accurately.
