EquiSync’s design is based on the 100’s of studies performed on the effectiveness of brainwave entrainment technology, and 1000’s of studies on the powerful benefits of meditation. If you are interested in better understanding the power of this technology and rapidly expanding field of research, then here is a very abbreviated bibliography, a very small sample of the studies out there:

I later learned that a Nobel Prize-winning scientist, Ilya Prigogine, had developed a theoretical model regarding the evolution of complex systems (like the human mind) that described these quantum leaps in awareness and brain-power I was experiencing—to a “T”—and explained why they happened! I read everything I could get my hands on about his work.
The training process allows you to consciously access deeper levels of your brain and consciousness. Your whole brain power and function expands. You become intuitive, relaxed yet focused, creative, your thoughts become clearer and information processing improves more and more. The left and right brain hemisphere synchronizes and you'll start using the full power of your left (analitycal - logical - Intelligence) and right (creativity - imagination - visualisation) hemispheres together. To say that this helps in all imaginable areas of your life is an understatement. You'll also begin to discover deeper realities beyond the physical. You become happier, more relaxed and balanced.
4. Be hesitant committing to any BWE system making wild claims. Profit fueled marketers with little to no experience in the BWE field have created a slew of low-quality entrainment systems on the market. These products typically make outrageous promises such as permanently enhancing the brain within minutes of use. Although BWE is a powerful method to improve the mind, it’s not a magic bullet.
Hello Chip, I did a little research for you and it looks hopeful. “Even when a person is deaf binaural beats can work. By putting the headphones with the binaural recordings behind the ear, the sound waves travel to the brain through the scull and entrain the brain just the same.” I can not corroborate 100% that this id a fact, however, if you are willing to give it a go I would love to hear how this technique works for you. Please keep my updated as to your progress and results. ~ Maya
Hemispheric synchronization: Whether it’s optimal or suboptimal to operate in a state of hemispheric synchronization remains unknown. Some speculate there are numerous benefits of brain waves operating in “sync” as a result of entrainment. There may be an increased communication between the right and left hemisphere of the brain – which could improve certain functions. However, it is also important to realize that increased hemispheric synchronization may not be as beneficial as many have speculated.
Delta (3hz – 0.2hz) – Deep, dreamless sleep. Intuition. Empathy. Brainwave expert Judith Pennington calls it the doorway to Universal Consciousness and “A radar that scans the environment and psychically picks up information and energy.” According to British physicist C. Maxwell Cade “There have been reports that delta waves appear at the onset of paranormal phenomena.” (More information can be found in Cade’s book The Awakened Mind)
There's no doubt that brainwave entrainment audio is a great technology for anyone who is interested in encouraging altered states of consciousness and it certainly can help people to reach deeper states of relaxation than they might normally have access to. I myself will often listen to brainwave entrainment music in order to enhance my practice of meditation. But let’s keep a balanced perspective, put all the marketing hype to one side for a moment and acknowledge that there is no brainwave entrainment technology in this world that can make you meditate like a Zen monk “at the touch of a button”, despite what some might like you to believe. The mind is NOT a machine. It moves through various states of consciousness in an organic way and at a natural pace. We certainly can guide and accelerate that process with the use of brainwave entrainment audio, but we cannot control it with the same sort of specificity and immediacy as you might control the speed of the car you drive.
There are many sources of binaural beats on the internet and YouTube to check-out and experiment with yourself – I recommend using headphones for optimal effectiveness. However, like most things, not all binaural beats are created equally (especially if they are free on the internet) and therefore not as effective or enjoyable to listen to. This is why I HIGHLY recommend the binaural beats created by master audio technician, music producer and meditation teacher, Cory Allen – which can be found here:
This music encourages a state of delta relaxation. Delta brainwaves are most prevalent during deep, dreamless sleep. The delta state is a mostly unconscious state that is essential to one’s physical, emotional, psychological and spiritual wellbeing. People who are able to achieve a state of delta relaxation through meditation will sometimes describe spiritual encounters and out of body experiences. The delta state is perfect for inducing profound spiritual experiences, healing and deep subconscious repatterning. Delta frequency brainwave entrainment music is also a fantastic cure for insomnia.

Brain Wave Entrainment is any procedure that causes one's brainwave frequencies to synchronize with a periodic stimulus (sound, vibration or light) having a frequency corresponding to the intended brain-state (for example, to induce a trance, dreams, sleep or relaxation.) It is also called the Flicker-response because of how staring at a campfire or the flickering of a burning candle can lull you into a state of calmness and serenity. There was an extensive article on this phenomenon by Gerard Oster in Scientific American in 1973. It may sound novel, but in many ways, this is old tech.
At the end of just two weeks of use (I was now into the Equisync II cds), I experienced for the first time ever, what my partner described as Nirvana. I experienced a complete dissolution of individual consciousness, felt at one with everything, and felt the deepest peace, love, and complete bliss I had ever, ever experienced in my life. Since you do all the research on this, you know what I’m describing. Unfortunately, language does not express it. I have never experienced mind altering drugs, but I recall watching a documentary of LSD research, and one of the subjects described the exact same “feelings” as I had when she had received a micro amount of LSD.

Deeper Meditation • Near The Stage Of Sleep • Vivid, Dreamlike Imagery • Creative Visualization • Feel More Open & Connected • Advanced Problem Solving • Super Creativity • Insight • Intuition • Inspiration • Deeper Subconscious To Super-Conscious Mind • Trance-like • GABA • Immune System • Serotonin • Endorphins • Acetylcholine • Lower Cortisol • Deeply Relaxed • Sleep Better • Emotional Intelligence

Insomnia: Perhaps one of the most promising uses of brainwave entrainment technology is for those struggling with insomnia. While the technology is unlikely to provide a “cure” it may help those who have a high level of arousal or are “keyed-up” – reduce their level of internal arousal and sleep. Specifically insomnia that is induced by excess stress (e.g. beta activity) would likely benefit from slower wave stimulation (e.g. alpha activity) to aid the brain in transitioning into sleep.
Tracks that move from alpha to theta can be a perfect vehicle for transitioning from a hectic day into a relaxing and rejuvenating sleep. Beginning with alpha waves takes you into a light but still alert meditative mind state where the difficulties of the day can be resolved and put to rest. Later, theta waves go deeper into the unconscious, preparing you for sleep and dreams.
However, if you are looking to do something more practical, like improve your mental sharpness, overcome attention issues, succeed at work, be more productive, you may want audios that target more of the alpha and beta ranges, and are created to put you in peak performance states of mind. In this case, a program like our Effortless Overachiever Bundle would be much more practical and helpful for you.
"I'm not writing with a question, but to THANK YOU for these CDs. I originally bought The Meditation Program with the intention of returning it, believing it to be nothing more than just 'another piece of hype.' Wow, I was wrong. This was the turning point in my life. You gave me strength, and stability, and literally changed everything around. I feel GREAT, and it's thanks to YOU. Thank you, thank you, THANK YOU for The Meditation Program CDs. I am a true dedicated customer of yours!"
By the end of just a few short days (3 or 4 of use), my constant “on edge” feeling completely dissipated. I had changed my lifestyle drastically to a very low-stress environment. All feelings of anxiety disappeared rapidly, but I was still experiencing something “physical.” I had trouble explaining it to anyone. I lashed out immediately at the slightest frustration. I tried to explain to those around me that it was something physically happening in my brain, but they were skeptical. Within less than a week of using the EOC cd’s, I noticed my tolerance level for dealing with people and situations had increased tremendously.
So I began to look at other instances in which the nervous system is being stimulated on a daily basis and discovered that sports science has a lot to teach us about this. Whether you are practicing yoga, meditation, using brainwave entrainment, or working out, it’s all pushing the nervous system. One of the things that sports science teaches us is that the nervous system waxes and wanes like a sine wave in its capacity to recover from, and grow from, the stimulation we give it every day. Static levels of stimulation, where you’re getting the same smack every day, day in and day out, do not allow for the fact that there are times when the nervous system is at its peak to handle the stimulation, and there are other times when the nervous system is in its trough, or valley period, when it is harder for it to recover from stimulation.

With so many thoughts begging for your attention each day, it’s hard to believe that most of them are the same ones you had yesterday. Actually, many psychologists who have studied the thought processes associated with our thinking patterns would agree that, on average, 90% of the thoughts that we become aware of throughout the day are the same thoughts that we have already experienced, over and over again. The reason we are so prone to repetitive thinking is because the brain is always … [Read more...]
I like it. I like the fact that I can just sit there and observe my thoughts and feelings and then go back to watching my breathing. It really does teach me to be centered and balanced. I look forward to the next several weeks. By the way, what I am doing now is meditating for 23 minutes in the early morning and again 23 minutes in the early evening. I’ll check back with you.
Gamma waves are the fastest brainwave frequency range. Gamma brain waves are believed to link and process information from all other parts of the brain. A high amount of gamma wave activity in the brain is associated with intelligence, compassion, focus and feelings of happiness. High levels of gamma brain waves have also been linked to improved memory and an increased sensitivity to sensory input. Low amounts of gamma brainwave activity have been linked to learning difficulties, poor memory and impaired mental processing.
Unlike many traditional therapies for dealing with stress, anxiety, depression or cognitive impairment, entrainment does not require a focused effort from the person having the therapy, as the brain instinctively follows the frequency. This makes it a much more effective therapy for managing some of these challenging conditions, by automatically inducing a sense of relaxation and a reduction in negative physical and emotional patterns.
Theta brainwaves are next highest in frequency above delta and are especially important for many people using brainwave entrainment and meditation because theta waves are at a threshold, forming a link between wakefulness and the subconscious mind. Theta waves bridge between our awake self and the creative and insightful understandings from below our conscious awareness, and while they are not common in awake adults, they are normative for children under 13 years old. 
That is a general assumption people make but there isn’t really much science to back it up. What we do know though is that isochronic tones are ineffective below 4hz, and possibly a bit higher. So for theta and delta entrainment you are best off with binaural beats. In my experience binaural beats will be very effective all the way up to around 40hz.
