Schumann Resonator

I got 2 of these from Amazon...careful that free returns are applicable.  I charged them up, turned them on and holy moly.....they do help with my system.   What I hear is between instruments, a definite difference in upright and electric bass, wider know...all the good stuff. At first I thought it might be increased brightness, but is still the same in that regard.  I still can't believe it, and will listen again tomorrow (saved the packaging for the return)...but today, I'm about to keep them.
I have two of them. They are a birthday gift from my oldest daughter's significant other. They do not help me sleep. I have no idea if they will do anything for sound quality as my system is down until the new speakers arrive and renovation of the media room is completed. As you might suspect I am doubtful. I never would have purchased them myself. He intended for me to use one on either side of the bed for health reasons.
Well, I just got mine... I got the shiny one with pretty lights. $35ish. Just plugged it in, I don’t know what it is doing, but it IS doing something. My system is no slouch and my room is as treated as it can be practically speaking... and damn, it makes a difference. Hard to quantify at this point, I’m just playing with it, but everything seems to be tighter, more distinct. Wider, higher, deeper. Very surprising. I put it right in front of my listening position at seated ear level. No idea if that is “right”. We will see.

What is that?

A free charge accusation against all users for no reason, save your uncuriousity coupled with blinders?

Or perhaps an audio enlightenement coming from your virginal working brain at birth ?

Nothing of that, probably only trolling stupidity....

All bets are on !

Myself i will safely  bet on the first or third .....
