***NOTE: (Last one) Please do research on which brainwaves do what before just trying out the first track you find! Also read descriptions of what frequencies are being used in the track, so you know what you are training your brain to! (Example: You struggle with OCD and have some anxiety. You see a track titled “Clear, Focused Thinking” and you try it out w/o reading the description. You either do not experience anything or you end up with worse anxiety/headache than before. If you knew before starting, that your problems were caused by too much Beta wave activity in your brain and the track was all low Beta ramping up to high Beta – you would not listen to it!)

Isochronic tones are the most recent and advanced method for brainwave entrainment audios. With isochronic tones, the same intensity is used for all tones, but they pulsate on and off at different rates. The speed, pattern, and rates of these tones can be changed and altered throughout the recording, and the brain will follow them into desired states. The use of isochronic tones opens up the ability to lead the brain into highly specific states, at specific speeds and intensities. This has opened up the doorway to producing both dominant and subdominant waves(i.e. an alpha brainwave state with subdominant theta waves), and the ability to lead the brain through different waves, at specific speeds (i.e. holding the brain in an alpha state for 10 minutes, then dropping it through theta for 20, and holding it in delta for five before bringing it back into alpha at the end of the recording.) This allows thousands of different possibilities in training the brain, and also makes the process of listening to these types of audios more natural, and more powerful. 

In the past few issues of the Advocate Voice Newsletter and the Fibromyalgia & Chronic Pain LIFE magazine, we have offered ideas about  several forms of cognitive behavior and mindfulness information.  In the chronic pain community these techniques combined with other therapies, including medications and alternative modalities, can help people sleep, function, relieve stress from pain and improve their quality of life.  This month’s app, Brain Wave, 30 Binaural Programs, is another tool to help introduce the idea of using your mind to help control pain and relieve stress.
"I have been using Quantum Mind Power for two weeks and today I feel that although the changes are subtle, I have been able to overcome many roadblocks in my personal life. I have ADHD and have been taking Adderall for 7 years, recently I decided that I need to stop and have cut my dosage in half with the intention of completely stopping within a month.  I have also just started teaching Pilates as a second job.....
Absolutely. Binaural beats were first discovered over 150 years ago, and their use in brainwave entrainment audio has been the subject of a great deal of scientific exploration over the last 35 years in particular. Millions of people use brainwave entrainment music to enhance their quality of life and to experience deep relaxation. In fact, brainwave entrainment technology is now used for more than just meditation. It is also used by a variety of practitioners and private users for improving self-confidence, stress relief, pain management, relaxation, improving and concentration and improving the quality of one's sleep. If you would like to read an objective third party report on binaural beats, please refer to this Wikipedia article.
I’m sorry to hear you’re having these troubles. First off, I disagree with whoever told you it was a good idea to listen to 6 subliminals a day. I suppose I would need more context to better understand. Are these binaural beats or brainwave entrainment audios? If so you are definitely listening too much, and can harm yourself (just as the article mentions above from over-doing it). Even if they are not brainwave entrainment audios, I cannot imagine it is effective or the best idea to listen to so much so often. I would pick one subject that correlates to the most important goal for you and stick with it until you have achieved it. Remember to steer clear of that tempting idea of getting “all that you want for nothing”. Even subliminals are a tool. You still have to use the tool to do the work.
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.
Hi Julie! You’re very welcome for the info. In answer to your question, I think some are probably good, and some not so good. There are many people putting brainwave entrainment out there these days and it is not so easy to figure out which ones are and aren’t of reliable quality without investing time and doing some research. I would say (in general) that paid products are probably better quality than free ones, but I couldn’t guarantee this is a golden rule. My best advice is to just do your research before spending too much time listening to the freebies.

When blended with musical sounds, brainwave entrainment frequencies induce specific states of mind, which are the result of those brainwaves, delivering them in pleasing and relaxing audio tracts for use with and without stereo headphones. For example, alpha and theta waves, because they exist at the borders between conscious and unconscious thought, are especially rich and useful for tapping into and stimulating subconscious processes.

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]
