The Sleep Shepherd is a fabric cap with sensors that  works with the brain’s natural structure to slow brainwave activity and guide the wearer to sleep, according to Sleep Shepherd LLC.

It incorporates “Virtual Hammock Technology” that induces a rhythmic sensation by utilizing the natural workings of the brain’s auditory center. The rhythmic pulse an individual “hears” when wearing the Sleep Shepherd is actually the brain deciphering the difference in frequency between the two tones that are played into either ear.

Sleep Shepherd touts itself as a drug-free and all-natural approach to getting a better night’s sleep. The cap is made of a stretchable and breathable fabric with built-in sensors and hi-fidelity speakers.
