Product description quoted from Amazon:

A wearable headband for sleep, developed with the aim of increasing deep sleep, waking up refreshed, and reducing daytime sleepiness.
Developed in collaboration with world-renowned sleep specialists and scientists, including professors from Harvard Medical School. It detects sleep stages from brainwaves and generates audio tones from the built-in speakers in the headband during deep sleep, thereby extending the duration of deep sleep.

The band length can be adjusted with a slider at the back of the head. *Please ensure your ears are properly covered by the headband when using.
