Research shows that parts of the brain and eventually large areas of the brain begin to resonate sympathetically with this "phantom" binaural beat. This is known as the Frequency Following Response. Subsequent research determined that a binaural beat frequencies drive brain activity into specific brain states. Thus, effortlessly and naturally, your brain activity slides into rhythm with this binaural beat, becoming organized and coherent. Within minutes, the sound frequencies start to balance the left and right hemispheres of your brain – creating a remarkable state called hemispheric synchronization and driving the electrical activity of your brain into powerful states, normally unattainable. Flashes of creative insight, euphoria and a deep sense of calm is often accompanied by this extraordinary brain state.
Some people are more sensitive to the audios than others – if you are one of them, be sure to take a break from what you are listening to and come back to it later. Always follow your body’s signals, and don’t hesitate to ask questions. You can always drop me a line for some honest advice on anything related to brainwave entrainment, meditation, holistic health, etc. You can also rest assured that all brainwave entrainment products listed here are of the highest quality – most of them I have used for years. I also highly recommend reading What Is The Best Brainwave Entrainment Product, too.  Don’t feel shy to bother the creators of the products themselves, and their support teams – you are in your full right to do so!
Your brain operates at certain levels of activity – the normal waking, active Beta, the meditative Alpha, the asleep-and-dreaming or deep meditative Theta, and the deep sleep/unconscious Delta. Beta is characterized by one thing we all want to get away from – stress.But that brainwave state has its place. It’s the action mode, and that’s the way it should be! If we’re not alert when we’re awake, bad things can happen, right?
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.
The brain will entrain to the strongest stimulus. If you combine binaural beats with isochronic tones, your brainwaves will entrain to the isochronic tones. If anything, when you combine the two I believe it makes the track less effective because it makes it harder for the brain to decipher between the two and synchronise to a single beat. There are lots of websites with compelling marketing about the benefits of combining the two together in some funky way, but I haven’t seen any research or lots of anecdotal feedback even to suggest it’s effective to combine them.
In fact, there is more to answering this question than meets the eye. As someone who’s also been skeptical enough to do the research, I am more than happy to explore the issue in great depth. The important thing to address here is what have you been told that Brainwave Entrainment would do?  Depending on whose site you’ve landed on you may have been promised different things.  The promised benefits of this type of product are a long list, and more things are still being added to it.  You may have been told that brainwave entrainment would help you meditate deeper, and rocket launch your spiritual evolution from doing so.  You may have been told that it would help your brain release positive neuro chemicals and anti-aging hormones that would improve your health and help you feel more positive emotions, overcoming anxiety, and you also may have been told that listening to brainwave entrainment on a regular basis would help your brain evolve, building a higher threshold to mental and emotional input, growing neural pathways, and synchronising the two hemispheres of the brain.
Naturally "click" with people – To get to the top, it takes good communication. World leaders get elected for their ability to communicate. Business visionaries have ideas that they make tangible by sharing their dreams with others. Pick up artists attract the opposite sex by noticing, and reacting, to subtle body language and saying the right things at the right time. What if you could easily and automatically just "click" with people, and gain instant rapport with your audience?
What I really like about iAwake is their standalone offerings. They produce quite a few audio pieces that are geared toward specific brainwave targets and desired results. These individual products aren't progression - based (you can listen to whatever tracks you want whenever you want), so there's no lengthy investment of your time involved. Also they're way cheaper (around $30-$50 depending on the product). In addition to manipulating brainwaves with sound, they pride themselves on their patented Biofield tech (look them up for more info).
While binaural beats are the most common technique we use for producing brainwave entrainment music, we do use other brainwave entrainment techniques such as isochronic tones, monaural beats and amplitude modulation. If these techniques have been used then you will find them mentioned in the written description of the music productions that include them. If not mentioned, then you can assume that binaural beats are the only brainwave entrainment technology in use.

Brainwaves, or neural oscillations, share the fundamental constituents with acoustic and optical waves, including frequency, amplitude and periodicity. Consequently, Huygens' discovery precipitated inquiry[citation needed] into whether or not the synchronous electrical activity of cortical neural ensembles might not only alter in response to external acoustic or optical stimuli but also entrain or synchronize their frequency to that of a specific stimulus.[16][17][18][19]
