It looks like a Watch. You wear it on your wrist when going to sleep. It has a tiny, but highly sensitive microphone that detects snoring and sends safe electronic pulses to the wrist. These pulses work similar to your spouse nudging you. They'll cause you to alter your sleeping position and stop snoring. The pulses aren't powerful enough to disrupt your sleep, but they will make you roll over, and the snoring will stop.
The product can detects snoring, then sends out weak electrical impulses. The snorer feels these impulses, and changes his sleeping position, without waking up and stops snoring.
