thank you for the suggestion, I will try to lower the volume to it's minimal. Perhaps it's because I tend to compare those tapes to the Holosync method which is much softer and totally subliminal. We do not hear any voices. I can relax much more with that method.
The introduction on the paraliminal tapes with the voices going from one ear to the other to tell us how to wear the earphones is like telling me I am so stupid I can't put on a pair of earphones!!!
