I had purpose to relax when i used a light and sound machine, but it didnt achieve this for me. It was the orion machine the one before the proteus, so maybe that could be a factor.
Could it be possible that maybe for some people binaural beat technology has no effect.
I have been using holosync for years on the basis of over people telling me to keep on with it and something will happen; plus someone told me that the pressure in my forehead was dorminant pyschic ability which sought of inspired me. However nothing ever did.
