I've used binaural and isochronic beats for months, they don't get you high. They help influence your brainwave frequencies. This is useful if you are already prepared to relax/meditate/dream. I find transitions to the low delta state useful for falling asleep quick. For full info [where I learned of them last year] on using these beats a google search works, or see wikipedia http://en.wikipedia.org/wiki/Binaural_beats or the Binaural Beatbox (www.sleepbeats.myshopify.com, (which is also a vendor of these products).

I find that drowning out these beats with other music makes them ineffectual. Your mind has to percieve the beat, in order for them to influence the operating frequency of your brain.
