My loops contain brainwaves. The range is more or less from 3 cycles per second (Hz) to 13 Hz. It depends on the loop. You should use headphones, because the spatial sound between channels is the most important to the proper functioning. The loops are highly recommended for chronic addicted masturbators. They give an excellent effect when you listen to them in the background to your favorite porn.
The loops DO NOT contain subliminal messages (or hidden commands, suggestions, etc). Brainwaves can ONLY help the listener to go into self-hypnotic state (bator’s state).
