It produces tones as you sleep that are supposed to help your brain wave patterns stay in the deep sleep pattern for longer. There is a sensor that you place behind your ear every night, and you put the headband on and connect it to that sensor. It isn't very noticeable after a few nights. It connects to an app so that you can see your sleep stats the next day.
