Philips just came out with a new headband that plays white noise to help your brain get to sleep. According to the company, its SmartSleep is the first wearable of its kind, one that is also clinically proven as effective for its intended purpose. Key to the device’s effectiveness, Philips says, are advanced sleep analysis algorithms alongside “customized audio tones.”
The Philips SmartSleep headband will be available this spring in the US, and it will cost $399.99, which at least is cheaper than Dreem. Device places a pair of sensors on the wearer’s head. The system works by monitoring the wearer’s brain activity and determining when slow wave sleep is decreasing. At that point, the speakers kick in and provide “audio tones” that nudge the wearer back into deeper sleep.
