I too just discovered this technology. It allegedly creates this effect by subtle phase differences in the stereo image. So, basically, it’s a Hemi-Sync type technology without the trademark.
I will probably try these at some point in the near future. I am sure that they can have some effect if used properly, but I’m extremely skeptical that they can produce the same intensity and transients that the ‘real deal’ can. Normally, if a reaction requires a chemical catalyst, it requires a chemical catalyst. No fancy wave-mechanical substitutes.
For instance, there is no WAY that the DMT dose can be anything like the real thing.
I would be interested in user reports as well.
