It can also be hung on a school bag. I wear lots of crocs and love this new design-- its like wearing a garden on your feet! It would be a better design if the push button that causes this was another kind of switch. it is a CHEAP $19. But when my bike almost blew away: I felt different though. Great product? it can easily fill a large room, campsite, or any impromptu location with really good sound. I put this in a "very" inexpensive strat copy, made by Glarry. The ties in the back are cute and mine did not have to be adjusted for fit. I?ll not use them very long and they will say low battery please charge. Well I ordered the multi colored and got tan and black they are confortable and warm just not the colors I wanted
