Inside the Theta Chamber℠ you will experience:
Binaural Audio Beats

I checked out the website and the part that worries me is "To induce a “Theta” brainwave state, creating suggestibility..." That's a lot of trust, allowing somebody to create suggestibility inside your head...I don't know about that.
