Brainwave entrainment can help you with this in a few different ways. First it has a tendency to help you relax very deeply. Just the act of relaxing daily will help to alleviate this stress and allow the body and brain to recoup. It also will stimulate the brain and body to produce more serotonin, dopamine, and melatonin, which will also help to improve your mood and keep you relaxed. But the greater benefit that comes from regular use of this technology is in its ability to enhance your awareness and perception. It can stimulate your brain and mind to have greater insights, greater flexibility and creativity in the decisions you make as you move through life, and this gives you a more resourceful means of finding your peace and resolving the problems and challenges you face in your life.
Headaches: There are several reports of brainwave entrainment providing therapeutic benefit for those suffering from general headaches or migraines. A study in 1985 analyzed photic stimulation within the theta range (5 Hz to 8 Hz) and discovered that this protocol provided significant headache relief. A total of 19/24 participants noted that the “slow wave” photic stimulation provided “complete relief” from chronic headaches and migraines.
So, what is binaural beats or binaural tones?  They are auditory (hearing) processing artifacts, or apparent sounds, caused by specific physical stimuli.  This effect was discovered in 1839 by Heinrich Wilhelm Dove and earned greater public awareness in the late 20th century based on claims coming from the alternative medicine community that binaural beats could help induce relaxation, meditation, creativity and other desirable mental states. The effect on the brainwaves depends on the difference in frequencies of each tone: for example, if 300 Hz was played in one ear and 310 in the other, then the binaural beat would have a frequency of 10 Hz.
Specific tones that resonate at certain frequencies are created and embedded within the acoustic architecture of the original waveform. Your brainwaves latch onto these embedded carrier frequencies and attune themselves to the same vibratory rate. Brainwave entrainment now occurs that is similar to binaural beats yet there is no need for headphones to deliver these entrainment effects.
This is why we have included not just audios in our program The Missing Link, but also include step by step instructions on how to meditate while listening to the audios, how to harness the chi in your energy system while going through this metamorphosis, and how to direct your mind in a way that all of this integrates in a way that propels you forward in the direction you want to go.
A common element in recordings incorporating alpha and theta frequencies is a steady but barely perceptible rhythm of the frequencies themselves. This subtle and calming pulse mixes with sounds of gentle breezes, distant bird songs, and the slow progression of deep synth notes. Underneath this, below the audible sounds at sub 16 hertz levels, other frequencies intermingle, deepening the merging of conscious and unconscious mind.

Only 4 of the participants reported no change as a result of the stimulation. Four years later in a study (1989) by Anderson analyzed LED photic stimulation for the treatment of headaches. There were 60 patients included in the study which involved Variable Frequency Photo-stimulation (VFP) with specialized goggles that contained light-emitting diodes.

Gamma brainwave states are the most rapid in frequency. Gamma has long been considered the brainwave that is able to link and process information from all parts of the brain. It is the frequency that brings with it the ability to process large amounts of information in relatively small amounts of time. Think of generating more Gamma activity as getting a processor upgrade for your brain.
Transparent Corp's Research Area is arguably the most comprehensive resource for collated brainwave entrainment research.   Update: the main research area on Transparent Corp's website is currently being updated, so it is offline.  However, you can still access their peer-reviewed research paper as a PDF here: “A Comprehensive Review of the Psychological Effects of Brainwave Entrainment“.

I have personally used Holosync, Neuroprogrammer 3, and now I'm currently using Brain Evolution System. They are all great programs within their own rights. Holosync is very pricey and takes many years to complete (6-10 yrs) for their 12 level program and has a hefty price tag of $3195 dollars for the complete set and it uses outdated binaural technology. Neuroprogrammer 3 doesn't have a set time limit for completion as you set your own pace and use whatever sessions you choose to use and you can get the ultimate version for under $100, but this isn't a program that you would use daily in most cases. It does use better technology ( binaural & isochronic ) but it more suited for specialized cases and can be used in conjunction with Holosync or BrainEv. I have just started using BrainEv and I am about to be into the second week. BrainEv uses state of the art binaural and isochronic technology and brings you through your states at a much rapid rate whereas Holosync focuses mainly on certain brain wave patterns during its sessions which could get your mind stuck in certain states because the brain gets used to the specific states it's been entrained to. Also, BrainEv takes just 6 months to complete and you can feel it working immediately. Holosync did do it's job but BrainEv takes the cake on this one due to the short duration of time it takes to complete and uses more advanced entrainment techniques that doesnt leave your mind in a static state. So I would difinately suggest using BrainEv ( first month is free; $299 for all 6 sets ) in conjunction with Neuroprogrammer 3 for more specialized brain training.

Changes in neural oscillations, demonstrable through electroencephalogram (EEG) measurements, are precipitated by listening to music,[20][21][22][23][24][25] which can modulate autonomic arousal ergotropically and trophotropically, increasing and decreasing arousal respectively.[26] Musical auditory stimulation has also been demonstrated to improve immune function, facilitate relaxation, improve mood, and contribute to the alleviation of stress.[27][28][29][30][31][32][27][33] These findings have contributed to the development of neurologic music therapy, which uses music and song as an active and receptive intervention, to contribute to the treatment and management of disorders characterized by impairment to parts of the brain and central nervous system, including stroke, traumatic brain injury, Parkinson's disease, Huntington's disease, cerebral palsy, Alzheimer's disease, and autism.[34][35][36]
