Wow. I use binaural beats every day as part of a polyphasic sleep regiment. This is one of the best I’ve used for power naps. 

I use binaurals anywhere from 1-3 times per day. Tough to find one that takes you deep enough to feel you got a strong enough nap session in 20min, but just as hard to find one that doesn’t take you too deep too fast, leaving your body CRAVING deep sleep when you wake up (your previous “theta deep sleep power nap” has done that to me). 

Might be my new favorite power nap, as it brought me deep enough in a short time span, but kept me in a light enough state to snap out as soon as I heard the chime. 

The voice at the end also added a nice comforting come up, as it happened to tell me to stretch right as I was starting to reach over my head
Excellent! Thanks for sharing your experience!
