Sleep improvement: There is significant anecdotal evidence that sleep induction and/or quality may be improved as a result of brainwave entrainment. While it is important to consider the placebo effect or simply the effect of a relaxing sound, many people have reported noticeable improvements in their ability to fall asleep and wake up feeling refreshed as a result of entrainment. Entraining frequencies within the slower wave ranges such as alpha, theta, or delta, may help individuals transition more quickly to those states.


To summarize all this, we can see that the type of product you choose plays an important role in answering that question – “Can brainwave entrainment damage my brain?” My personal advice as a long-term user of the technology is to Be selective about what brainwave entrainment audios you download from the internet, and make sure to follow the instructions! 
Another general benefit of using brainwave entrainment in general is that it increases and promotes whole-brain functioning, meaning that the two hemispheres of the brain grow more connections and exchange information more easily. This can help more starkly rational people become more intuitive, and more airy-fairy people become more focused and logical.
A study published in Electroencephalography and Clinical Neurophysiology by Paul Williams and Michael West in 1975 examined the brainwave states of people experienced in meditation while using photic stimulation, and another study by Leonard, Telch, and Harrington in 1999 examined the successful use of brainwave entrainment techniques for attaining meditative states in subjects.
Hello Chip, I did a little research for you and it looks hopeful. “Even when a person is deaf binaural beats can work. By putting the headphones with the binaural recordings behind the ear, the sound waves travel to the brain through the scull and entrain the brain just the same.” I can not corroborate 100% that this id a fact, however, if you are willing to give it a go I would love to hear how this technique works for you. Please keep my updated as to your progress and results. ~ Maya
These brainwave entrainment devices are also known as brain machines, dream machine or psychowalkman, AVS device or brainwave frequency generators. Optimize your peak performance and event-related potential (evoked potential via human enhancement). It is now possible with audio visual stimulation (AVS) mind machine brainwave entrainment. We have the best mind machines available. The revolutionary bluetooth MindLightz  provides the worlds first completely wireless light and sound experience as well as iphone/itunes music inegration. We have the most popular devices including The Mind Alive DAVID Delight Pro, the Proteus from Mindplace. Now you can experience altered states of consciousness, ganzeld effects and Hemi-Sync sensations for inner peace, personal wellness, accelerated learning, meditation, behavior modification and deep, restful sleep.
Rather than discontinuing my meditation practice altogether, I instead began researching methods of increasing the effectiveness of meditative practice. This seemed an inevitable decision for me in light of the undeniable improvements I had witnessed in response to previous experience with meditation. This resulted in my eventual re-discovery of brainwave meditation programs brainwave synchronization. I had used a few different such products previously, but none that seemed effectively designed to meet my specific needs. After deciding to try a particular brainwave meditation program, I found it to greatly assist me in producing all of the previously experienced benefits of meditation, but in a shorter period of time and in a much more focused manner.
Meditation enhancement: There are several companies that sell brainwave entrainment sessions specifically designed to enhance meditation. The sounds provide a stimuli to focus on during the meditation, and the brain waves naturally shift towards the frequency provided. Whether meditation is actually enhanced by brainwave entrainment is a subject of debate. However, advanced meditators commonly experience brainwave synchronization – which the right and left hemispheres display the same frequency brain waves.  While there are scientific benefits of meditation, it is unclear as to whether they are enhanced, hindered, or unaffected by adjunctive brainwave entrainment.
At the beginning of May, I decided to change over to EquiSync because it’s much cheaper and let me experience the deeper levels sooner. At best, my blood pressure has been down to 66 and after cups of tea and food, back up to 76-80 which is regarded as acceptable. I was able to achieve these wonderful results in less than 6 months of daily practice of meditation using audio-beat technology.

Subsequently, the term 'entrainment' has been used to describe a shared tendency of many physical and biological systems to synchronize their periodicity and rhythm through interaction. This tendency has been identified as specifically pertinent to the study of sound and music generally, and acoustic rhythms specifically. The most ubiquitous and familiar examples of neuromotor entrainment to acoustic stimuli is observable in spontaneous foot or finger tapping to the rhythmic beat of a song.
