Daeyang Education and Communication (E&C) has sold already a total of 1.1 million units of its MC Square light and sound machines mostly in Korea.
The MC Square consist of a small Walkman-sized control unit, light emitting diode (LED)-installed goggles and stereo headphones.
Light and sound impulses are supposed to stimulate brainwaves.
The company got The University of Pennsylvania School of Medicine (Penn Medicine) and Thomas Jefferson University to do a study on the effectiveness of the MC Square device. Apparently the results are supposed to come later this month. Daeyang Education and Communication thinks they can with a positive study convince consumers that their product actually works.
