They are a useful and effective tool that allow you a structured means in which to entrain your brain into a desired, new brainwave state using an intended set frequency range of the audio track. Frequency ranges for desired sleep, recovery and deep meditation states to different/higher frequency ranges for performance “flow-states” and high-level focus and calculation.
When making an educated decision on what product is best for you, it is important to have a general understanding of how the technology works, and what the benefits are of visiting the specific brainwave states.  Please click the link to visit a more detailed article –  How Does Brainwave Entrainment  Work, and the benefits of Alpha, Theta, Delta, and Gamma brainwaves.
The immobilization response. If you’ve experienced some type of trauma and tend to “freeze” or become “stuck” under stress, your challenge is to first rouse your nervous system to a fight or flight response (above) so you can employ the applicable stress relief techniques. To do this, choose physical activity that engages both your arms and legs, such as running, dancing, or tai chi, and perform it mindfully, focusing on the sensations in your limbs as you move.
I definitely NEED (& can feel a difference mentally) Gamma the most. Beta and Alpha do better my processing. Theta waves are TERRIBLE! My normal symptoms increase when listening to those frequencies! Delta has been helpful for me around nighttime. It has helped my sleep on occasion. *Note: Do not listen to higher frequencies (Gamma, Beta) before bedtime! They will keep you very alert.
Most of our Royalty Free brainwave entrainment music uses an audio technology known as "binaural beats". These binaural beats are embedded in the music in order to bring about desirable changes in brainwave activity, thereby encouraging various states of relaxation, deep meditation or sleep. When played with headphones, you may be able to hear the binaural beats as a subtle pulsing sound beneath the music.
Other entrainment methods sometimes used include autopan modulation that moves sound in an 180º arc to create a desired tone. Harmonic box entrainment, invented by James Mann, uses a layering of binaural and monaural tones that alternate between ears, requiring headphones. Sound modulation and filtering, amplitude modulation, and pitch panning use diverse sounds to create rhythmic pulses matched to the desired brainwave frequency. 
Healing music to calm your mind. If you feel an uneasiness, disquiet mind or have the jitters, then this music may just be what you’re looking for. With calming isochronic tones that help you relax (going from 12 Hz – 8.4 Hz and back to 12 hz again), the music has been specifically  selected for it’s tranquility.

Exercise can be an effective component of a stress management program for many individuals and should be recommended to help those who are dealing with acute, acute episodic, or chronic stress. An advantage of incorporating exercise into a stress management program compared with other stress management techniques is the well-documented physical and psychological health benefits of exercise. However, it is important to remember that exercise is only one component of a stress management program, and there might be situations that require assistance beyond the expertise of a fitness professional, especially in working with individuals who are experiencing acute episodic or chronic stress. Although exercise might be effective in helping an individual feel calmer who is dealing with these types of stress, it will not solve the problem of major chronic or regular stressors. It may be necessary to refer these individuals to resources who can help them to address their stressors, such as a psychologist or other health care providers.

It was a few months after the birth of our second child that I came to truly understand the effects of long-term sleep deprivation. Constantly waking up at 1:00 or 3:00 a.m. soon turned daily life into a hazy blur. I'd often find myself lying in bed, anticipating the next round of crying, or later in the night, I'd be tossing and turning for ages after being woken up. It's no fun whatsoever to drag yourself out of bed every morning with dark circles under your eyes. During this time, it became … [Read more...]
It is important to take an objective look at published scientific evidence to determine whether brainwave entrainment is an effective treatment for certain conditions and/or symptoms. Most preliminary evidence suggests that while the technology will not cure any condition, it may be a successful adjunct treatment when used carefully with the proper protocol.
By the 1980s, entrainment technology had merged with advancements in microelectronics technology, making it possible to develop even more sophisticated audio and visual brainwave entrainment products for the marketplace. In the last two decades, a number of scientific studies have reported brainwave entrainment as an effective remedy for ADD, academic learning problems, and improving memory and cognition.

As soon as this session begins, the 10Hz frequency kicks in, helping to release your worries, brighten your mood, and encourage the release of the happy hormone, serotonin. This is followed by progressive patterns of euphoria-inducing beta frequencies, each building on the last, helping you to get you energized and feeling great. The uplifting background also gives this session an added kick. An excellent way to start the day – but don’t use it too late, as it may disrupt your sleep patterns.
Proceedings of the 9th Conference on Interdisciplinary Musicology – CIM14. Berlin, Germany 2014 first group it increases, and for the second decreases. Experimental group did not fall asleep but maintained a relaxation state after the stimulus, while control group achieved unconscious relaxation but the effects did not hold. The STAI “State” indicated that stress increased after the stimulus for control group (see graph A1.2). 14. CONCLUSIONS • Delta (20-200) and theta (20-100) brainwaves are the ones that have greater amplitude (microvolts) in both groups. Results are clearly shown in graphs A1.5 and A1.10. Graph A1.5 Theta Graph A1.10 Delta • Higher frequency EEG waves such as beta waves have less amplitude. This happens because they are not synchronized and have more phase differences in both groups. • An increased alpha parameter is higher in the experimental group, which indicates that they achieved conscious relaxation. In contrast, the control group showed higher delta waves and presented signs of deep sleep during the experiment. Control group also possibly reached REM (Rapid Eye Movement) sleep halfway throughout the stimulus due theta waves presence in the EEG. • Beta waves are higher in the control group from s = 507 to s = 624 because of unexpected sounds in the stimulus (traffic noise appeared in the original recording). • Both stimuli induced relaxation, but it is important to point out that a person can relax without falling asleep. In this way the binaural stimulus worked better. • It is likely that the control group fell asleep with the nature sounds stimuli because lack of stimulation. • Contrary to what we expected, theta binaural waves didn’t induced FFR in experimental group, although they helped to achieve conscious relaxation. • Delta waves were higher in the experimental group during post-experiment measurements. This suggests that relaxation states were maintained with the absence of stimulus. • Presence of Alpha waves was reduced during deep sleep. This evidence is supported by the control group’s Delta values. • In the absence of stimuli, Delta wave values of the control group decreased, which means that relaxation effects did not prevail. • The effectiveness of an anxiolytic may be measured through the relaxation degree during stimulus and whether its effect endured or not. • For further evaluation of coherence [17] between brainwaves in both hemispheres and the ERP, the use of a 10-20 EEG system is recommended. • Post-experimental STAI “State” tests results are lower in the experimental group. This means that Theta binaural waves were a better anxiolytic than the stimuli (nature sounds) used in the control group. REFERENCES [1] Huang, T., & Charyton, C. (2008).

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 believe that there is a frequency at which a brain functions, they can vary depending on circadian rhythm or other factors. You can check the various effects on the brain caused by varying frequencies. Check this link -> Binaural beats. When we expose our brain to isochronic/binaural beats, it has a resonating effect on the brain, i.e. the brain starts to alter its frequency in order to synchronise with the tone. Once the specific frequency is achieved, you will have the desired effect (depending on the specific frequency you are trying to induce).
As you close your eyes, this session quickly lulls you down into deep delta sleep, where the body recovers and grows. The session starts at a waking frequency, soon taking you down deep into delta, with stops at sigificant beneficial frequencies such as the de-stressing 10Hz, the grounding 7.83Hz Schumann resonance (SR), and the deeply relaxing 5.5Hz. You’ll soon find yourself in a deep, healing sleep. If you’re particularly stressed, try listening to Power Chill before starting
