Cool! I was just thinking about this topic and wondering if I should post it.
The info I have so far is about Centerpointe, and they have a website which goes in to a lot of technical detail. The cost of the program is pretty high ($159US), but they have a free demo which I have tried. They claim that it causes permanent positive changes in the brain, helps unite the hemispheres to achieve 'whole brain thinking', and yes you have to use headphones. I uses the concept of bi-aural beats, different audio frequencies in both ears. Here is some infor from www.centerpoint.com :
"In 1985 I became aware of, and began experimenting with, a remarkable audio technology I found mentioned in a research paper published in Scientific American (October 1973) by Dr. Gerald Oster, a research scientist at Mt. Sinai Medical Center in New York. This audio technology, when placed beneath soothing music and listened to with stereo headphones, produces some absolutely mind-blowing experiences (and benefits) for the listener:
Profoundly deep meditation...
Dramatic increases in the production of a whole variety of beneficial brain chemicals, including pleasure-causing endorphins-as well as a number of others proven to slow aging and increase longevity and well-being...
The release and falling away of dysfunctional mental and emotional patterns (such as anger, fear, anxiety, depression, sadness, substance abuse, self limitations, etc.)-even those that have stubbornly resisted other methods...
Increased learning ability, enhanced creativity, greater intuition, improved focus and concentration-and (even more amazing) greatly increased personal self- awareness (scientists call this combination "whole brain functioning")...
Dramatically lower stress levels, and an increased ability to deal with whatever comes at you from the world, calmly and clearly. You become more relaxed, less anxious, more centered, more peaceful, and more connected to others...
Achievement becomes easier, and without the same feelings of anxiety and stress. Taking the risks necessary for success doesn't seem so scary anymore. Good things begin to just "happen" in such a way they almost seem to fall right into your lap...
The need for sleep decreases, yet aliveness, vitality and energy increase! "...
In a before and after study of 19 people using Holosync audio technology the following changes were noted in levels of DHEA, cortisol, and melatonin:
In just three days, over 68% had increases in DHEA levels, with an average increase of 43.77%. Several people had increases of 50, 60, even 90%.
Cortisol, on the other hand, was down an average of 46.47%, with positive changes in 68% of the people, and with several people having decreases of 70 or 80%.
Melatonin levels increased an average of 97.77%, with positive changes happening in over 73% of the people. Many had improvements of 100, 200, even 300%.

The only cautionary info I have found is that according to some MKULTRA victims this type of technology was used to help program them along with serious trauma. Soooo, it seems best to make sure you know WHO makes the tapes so you are not inadverantly 'programmed'.
Ooops, gotta go! The kiddies are awake and mommy is going to make some blueberry pancakes. I'll get bake to this later. Have a great day everyone!
