For a less technological version of entrainment, several different musical products are available which allow you the choice of brainwave state. The Brainwave Suite is one example of this music based system. This four CD volume allows the choice of alpha, theta, delta, or an alpha/theta mix. Another choice of this type is the “Five Directions” CD set. Any of these types of music requires headphones, as the binaural technology cannot be processed by the brain when the sounds are played by speakers.
