Pairs with cell phones, tablets, laptop and other wireless Bluetooth enabled music devices. The hat is washable (after removing the ear piece inside the hat).
Promising review: “Can’t say enough about how cool this hat is! Paired instantly with my iPhone 6, and the ease of use is amazing. Great quality hat, and to my surprise, it has awesome sound. The controls aren’t too big and uncomfortable while wearing. I am gonna buy several more, as there are quite a few styles and colors, and I love wearing hats.” –Y2jimmyk
