These are super fun! They have 7 different modes that can be clicked through and surprisingly, they realy aren't as distracting as I thought they might be! They come with zero directions and no adhesive so unless you read the Amazon page for directions, you are pretty much on your own. There is a mini 'computer' that attaches to a hair clip that fastens to the back underside of your hair, or anywhere else you may find it convenient. It is a little awkward with the wires coming up around your face but they could be hidden artistically. These really are cool, I can not wait to wear them out!
