I have always had trouble sleeping but since wearing these headphones I am now sleeping a third of the night heavy, a third REM, and a third light. I wake up feeling refreshed and sleep the whole night which I have never done in my life! I also no longer get woken up constantly by my partner's snoring. These headphones have changed my life and my relationship. They are amazing! I have never slept better.
Pros and Cons:
Bottom Line: Yes, I would recommend this to a friend
