Sleep deprived? Can't seem to shut eye? Then you might need the help of some tech. This headband apparently uses 'brain-training' sounds that help users to get in to deep sleep. This is where your body recovers, and it's an important part of sleep.

The headband will play humming sounds called binaural beats that will lull the brain into a meditative state, and then into deep sleep.

It's now on Kickstarter.
