it really works

Seriously works! Tried without headphones but Its not as effective. Different tones played with music helped ease pain in my back. Not sure exactly how it works Just glad that it does! I was very skeptical at first but I started noticing when I would listen to the track before starting my day, I had less pain in my back. Try it out for yourself. I think its a great addition to yoga.
