I am one of the fortunate ones who received a free demo of your product. I do believe your product corrected damage to my brain from a childhood concussion. Immediately upon use, I became aware of sounds, drainage and even discomfort behind my right eye and the lower right side of my skull. This continued for a week of using the product daily. I was about to give up using the product when all discomfort stopped, and has not returned. I do believe your product should be used for childhood head trauma. Even though the brain is only bruised, a life can be altered immensely. I love my Equisync II and will use it daily and with confidence.
NeuralSync™ is the ONLY technology that utilizes FOUR SEPARATE yet synergistically-interactive frequencies precisely calculated to induce each mental state offered in our catalog. Our exclusive 4-W.T.S.P.™ technology creates waves in a balanced 4-dimensional pyramid that are collectively complementary and interactive. Unlike other related programs that use only a single binaural beat or isochronic tone frequency (or several in sequence), NeuralSync™ applies all four simultaneously to immerse your brain into targeted and harmonizing perspectives.

I first became aware of brainwave meditation programs  and brain waves when researching alternative methods for treating the bipolar disorder I had been unsuccessfully living with my entire adult life. I eventually learned a method of releasing difficult emotions on the spot, which I then practiced extensively, and consequently found it easier and even desirable to meditate for fairly lengthy periods of time. Though I took up meditation as a serious daily practice and experienced many undeniable benefits, I nonetheless intermittently experienced life-debilitating bouts of mania and severe depression, often resulting in chaotic mixed states and an inability to maintain daily social functions. During these times, it became nearly impossible to sit in meditation.

Memory: There is not sufficient evidence to suggest that brainwave entrainment improves memory. However since cognitive function improves as a result of entrainment, short and/or long term memory may be improved by stimulation with certain frequencies. While lower frequencies may be beneficial for recalling certain memories, conscious processing of the memories generally requires sufficient beta.
Just my FIRST session I felt like I successfully achieved a theta state of meditation….I came out of it feeling extraordinarily renewed and with this profound insight of “everything is going to be ok”….this was all from my FIRST session. I cant wait to continue this on a regular basis to see where it leads….one day I hope to achieve the deeper delta states…
Additionally, most of the studies have been conducted with extremely small samples and the touted benefits are vague. When studying the effects, it would be beneficial to hook each participant up to an EEG, note initial brainwave activity, then post-entrainment, note any changes. Although certain conditions share similarities in brainwave activity, this is clearly not always the case.
The same goes for brainwave entrainment.  You can’t just listen to an audio as many times as you want and expect that more is always better.  In a very real way, you are “exercising” your brain.  You are pushing it to build new neural pathways, to communicate with itself in new ways, and to adapt to a new kind of mental stimulation.  This is incredibly good for you, but there is a limit that you must observe.

First of all thank you for your amazing website, I have a question regarding these matters, I can make both binaural beats and isochronic tones for myself but I doubt for low frequencies states (Theta and Delta) which one is better? Because I searched a lot and saw that binaural beats are better for low frequencies and for high frequencies (Beta Gamma Lambda….) isochronic tones are more effective. Also, for Alpha states some said isochronic and other said binaural.
My voice is relaxing and relaxation is pleasurable. These mental directives soothingly lull your conscious mind into ending its internal dialogue. It is the conscious mind that does ALL of the worrying, nagging, second-guessing and basically all of the incessant mental chatter and constant inner dialogue that can keep us trapped by our own view of reality, whether these views are good for us or not.
Delta brainwaves have the slowest frequencies, ranging between 0.1 and 4 hertz, and these are the brainwave states associated with deep sleep, trance states, and unconsciousness. Few people can remain awake during delta brainwaves states, although this state is recorded in awake infants between ages of three months and one year and also in babies just before birth. Delta waves are also linked with increased production of HGH, DHEA, and the neuro-transmitter serotonin.
Generally, the established brain entrainment technology has been to use various static levels, lowering the carrier frequency of the binaural signals over time. By doing this, you basically increase the resonant power of the carrier frequency to resonate more deeply with the resonant frequency of the brain and the nervous system. This process pushes the nervous system over time. The limitation I find with this system is that it takes a static approach, in the sense that it gives the nervous system the same degree of stimulation day in and day out. The idea here is that if you keep whamming your nervous system with the same stimulation on a daily basis, it will eventually kick in and learn. Then your nervous system and your brain will jump to the next level.
 Theta brainwaves are the next level down from alpha, at a range of 4Hz-8Hz. These brainwaves commonly occur just before sleep, or in the lighter stages of sleep. They also occur while you are day dreaming, or when you experience a strong emotion. It is not so common for an adult to produce prolonged theta brainwaves unless they are an experienced meditator, or perhaps deeply involved in an intuitive art such as music or painting. A dominant theta brainwave state is one of deep relaxation (deeper than alpha) and natural healing. In prolonged dominant theta states, the brain’s sodium/potassium ratio resets and balances itself, curing mental fatigue, and improving the brain cells ability to transport and exchange neuro-chemicals. Without the means of deep meditation, or brainwave entrainment technology, this benefit would only otherwise come from sleeping or napping.Theta is known as the one of the best states for communication with the subconscious mind.
The program uses special ‘brainwave’ sounds to meditate for you. That means you don’t have to actively try to quieten your mind, stop fidgeting, or focus only on the meditation. And you don’t have to reschedule your day. Each session lasts just 12 minutes, and you only need to meditate a few times a week to reap the rewards. Just sit back and hit play.
Two people with ADHD for example could have completely different ADHD subtypes. One could have inattentiveness as the primary symptom as a result of high theta waves, and the other could have high beta-2 waves as feel hyperactive. While generalized entrainment protocols should be studied, it is important to consider that each person may respond differently to the protocols; each person has a unique neural footprint.
No matter what you use: USE it. At least for a couple weeks.  And have realistic expectations...  Brainwave Entrainment is not some pill or quick solution (even if there are some sessions that usually give almost immediate results e.g. for sleep induction or pain relief), it is a tool that requires training and works best in combination with good breathing / meditation techniques.
3) Theta waves – these waves exist between 4 and 7 Hz. This state is commonly referred to as the dream or “twilight” state. Theta is associated with learning, memory, REM sleep and dreaming. Memory development is also enhanced while in this state. When in a theta brainwave state, memory is improved (especially long-term memory), and access to unconscious material, insights and creative ideas is increased.

From the deepest, sincere, compassionate, and loving part of my soul; I offer thank you. : ) By saving me, I believe your organization did a service to society as a whole, for now I am like a ripple in a pond that will reverberate good vibes to all who I come into contact with. I express compassion, understanding, and knowledge to all who I see need your life saving, and healing product. Like a missionary I desire to spread it; for it is pure, good and loving to my fellow man.
I would like to start off by saying that many bold statements are made about this technology from people who have a self-interest in promoting or rejecting it. We have to face the truth by accepting that people are profiting from brainwave entrainment, and as a result of this other groups of people are being affected in a negative way (from a business point of view). This is a reason why you can find all kinds of claims from someone who has never used or tested the technology.  Unfortunately I have found in my own personal journey of using brainwave entrainment that there are some great people out there making some great products, and there are also some irresponsible and untrustworthy people out there trying to grab a slice of the pie.
A study that tested photic stimulation for reduction of poor behavior in ADHD children found that 15 sessions of photic stimulation between 12 Hz and 14 Hz resulted in behavioral change. This behavioral change was measured using the Achenbach Child Behavior Checklist – which accounted for not only the parent’s perspective, but self-reports from the children. Statistically it was stated that behavior improved up to 70% in the stimulation group compared to controls.
Hi Jason, thanks for all the uploads to youtube. I’ve been using them in work recently to help me concentrate and relax. I like the music tracks that you’ve chosen to overlay the tones. A couple of times in the last 2 weeks I’ve experienced the wavy pulse like sound, similar to the tones in my left ear. I wasn’t listening to tracks at the time or that day. It doesn’t last but it feels a bit strange. I wondered if I might have been listening to the tracks too loudly and that it was almost like a type of tinnitus. I’m curious to know if anyone has been in touch with you in the past to say they’ve had a similar experience?
