they work. I received compliments on it, that it looks nice and looks stylish. O fone direiparou de funcionar com menos de duas semanas de uso. Very disappointed and an inconvenience. The size 7 was too large for me but the size 6 fit perfectly. They also included a little clip in case I decide to clip it onto the outside of my backpack, which I have yet to try. These Chelsea?s look great and are exactly what I was looking for. I almost bought one that cost twice as much but I?m glad I bought this one. The rack itself is great and so far holds more than most clothes racks. The speaker did not work at all.
