CNET’s Michael Franco tests out the Sleep Shepherd, a nightcap that reads your brain waves and plays calculated tones in your ears.
“The rhythmic pulse you hear when wearing the Sleep Shepherd is actually your brain deciphering the difference in frequency between the two tones that are played into either ear,” says the company. “This natural ability, contained within our brain’s structure, creates a soothing sensation of swaying back and forth as though the wearer is in a hammock.”
Unfortunately, I didn’t exactly feel like I was in hammock. I felt more like I was inside a giant wine glass that someone was making hum.
