One of the more fascinating aspects of what brainwave entrainment does, long-term, is the growing of your mental threshold, and your self-awareness.  I have been a participant of the Holosync Solution for several years, and its maker, Bill Harris, has gone to great lengths to explain why this technology does this.  Much of his research is based on the concept of Entropy and Open Systems, (an idea that nominated its discoverer for a nobel prize).  The brain being an open system, and the technology being a specific type of entropy, this technology has been shown to help the brain reorganize itself at a “higher level” through the growth of new neural pathways. This basically means that 
ADHD: In 1997, various researchers conducted a study testing whether children with ADHD (attention-deficit hyperactivity disorder) would benefit from audio-visual entrainment in a school setting. The researchers entrained a small sample of 34 students from 2 different schools. They were given audio-visual entrainment for a period of 1 month and 3 weeks at various times throughout the school day.
Recently developed entrainment software has been designed to correct specific imbalances in hemispheric activity associated with undesirable mind-states. For example, people suffering with depression often have more activity in the right hemisphere, and specially designed brainwave music decreases this activity while increasing activity in the left hemisphere, reducing depression.
There is a certain point where the promised benefits of brainwave entrainment become more esoteric, and based on internal, subjective experience of oneself.  A few examples would be that listening to brainwave entrainment on a regular basis helps to increase one’s self-awareness, or that it increases mental “sharpness”, or helps to heal emotional trauma and increase your tolerance of stress and negative emotion. 
That all said, we are all different and have our own different limits. So I generally advise that you just be aware of how you are feeling, and if you feel like you are getting a bit fatigued from it, it’s probably time to stop or at least take a break. When listening over long extended periods, I recommend that you keep yourself well-hydrated. Your brain needs a good supply of water to function well, especially if you are studying hard and increasing your brainwave electrical activity.
In BrainAscend, each brainwave frequency is stimulated for several minutes before progressing deeper.  Much like a staircase type of progression, but with small and smooth steps. This is the most effetive way and also stimulates the release of "feel good" brain chemicals such as serotonin which makes you feel happy. This chart shows the range that each level covers as well as the whole program.
Since most of us spend our days in the beta state, EquiSync excludes the beta brainwave frequencies, and entrains only those responsible for the most beneficial brainwave states: alpha, theta, and delta waves. The two charts on this page illustrate the basic benefits of each brainwave state as well as the basic targeting of the EquiSync programs 1, 2, & 3.
There are also ways of directing the entrainment pattern to further stimulate the brain in a desired way. Not all audios stay at the same frequency the whole time. Some will increase and decrease for a desired effect. Some will blend different beats at certain time to exercise the brain in a specific way. It is things like this that separate a good audio from a mediocre audio, and the difference between the two is undeniable when compared.
-Other Specialized Entrainment Methods: There are a few other things to consider like whether the audio creator uses binaural beats, monaural beats, or isochronic tones when appropriate for the desired effect of the audio. Or whether they use other entrainment methods as well, like volume modulation, pitch modulation, or panning from right to left of the headphones to further improve the immersion of the audio.
Both brainwave entrainment and neurofeedback deal with brainwaves, but the similarity stops there. Entrainment pushes your whole brain into a pre-determined state, while neurofeedback teaches you how to move specific parts of your brain on your own. It is the differeence between forcing the brain into a given position, and skills building so you can move it there yourself.
