anyone tried this? it definitely goes into "magic" here
for me, this thing has definitely a effect, i tried a cheap squarewave generator before and it also had a effect, but more of a disturbing one... but these variable chinese sinuswave generators are new, there are some expensive schumann generators out there with sinuswave but nothing from china was comparable until this device..
So... i did actually try a few frequencys, if you set the device to a solfeggio frequency of say 417Hz you actually expierence the same effect as when listening to binaural beats.... without speakers involved..., i tried multiple frequencys and the effect was always the same as the binaural/monaural counterpart.. (tho dont get confused with the youtube videos embedding more than one frequency...)
lately i found out i actually like around 7,4Hz way more than 7,83Hz or 8Hz .... the funny thing with the schumann frequency is this: the schumann frequency rises in summer and lowers in winter on average .... (and also rises on average very slowly trough time) the "feeling" you have on summer vs winter can be to some degree replicated with adjusting the frequency between 7 and 9 Hz... dont you feel sometimes a bit "sick" from the heat in summer? try 8Hz or 8,5Hz (similar effect imo)... some thoughts on my own research on this...
the real question tho.... is this "safe" ? i dont use it constantly just for that reason, also the effect can be quite overwhelming over time imo then you just feel the relief once you disable it... specially if 7,83Hz or up doesnt suits you..
Take this post as it is, i know how controversial this is, this is my own opinion and you can either think im crazy or try it yourself and you may be surprised (specially if binaural beats work for you...) and kinda scared because what will THIS electromagnetic sending device do AND what might 2,4Ghz or 5G actually do?
because most young people never expierenced it how its like to not get blasted with RFI/EMI all day long, its easy to say that it doesnt matter...
if schumann frequency has an effect i truly believe 2,4ghz can too, tho im not "scared" of it, thats where things get silly i guess... im just saying to some degree it could alter our perception, just like the schumann frequency can, most people are just not aware of these subconcious things going on, specially if you never compared A/B ..
if you wanted to always try a schumann generator, get the variable sinustone one i posted above, not cheaper squarewave ones...
