Binaural beats, real or fake? ever heard of i-doser? what are side effects? can these beats be addictive like drugs? thank you

Yes: binaural beats could help induce relaxation, meditation, creativity and other desirable mental states. The effect on the brainwaves depends on the difference in frequencies of each tone: for example, if 300 Hz was played in one ear and 310 in the other, then the binaural beat would have a frequency of 10 Hz.

I-doser: Research into the neurological technology behind I-Doser is sparse.Peer-reviewed studies exist suggesting that some specific binaural beat mixes can affect aspects of mental performance and mood,act as analgesic supplements or affect perceptions,but there have been no formal studies of any effects of mixes particular to I-Doser. Researchers from OHSU have expressed skepticism based on small trial
