I like the idea of the Ultimas, but haven’t found the time to listen to one all the way through daily with headphones.
Have listened through the speakers on my Google Pixel, but at this point it seems pretty clear that has no effect, or if it does it is too minimal to notice. I have suspended such experiments.
I continue to listen to my Michael Norman NLP/Hypnosis track most nights. It seems to shift thought patterns, moods and feelings and reduces anxiety.
