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 clarity....space between instruments, a definite difference in upright and electric bass, wider soundstage...you know...all the good stuff. At first I thought it might be increased brightness, but no....it 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.

Day one -- Purchased two and had one on each side of the bed stand.  My wife and I both woke up with headaches, an no we were not hungover.  So they did nothing to help with sleep.  We will try a couple f more days. Then we will move to behind the speakers.

The cheap devices use a square wave which can give people headaches, a sine wave schumann device does not.
Earlier in the thread I suggested optimism or confirmation bias accounted for the perceived benefits of homeopathy and resonators. I hope it is coincidence that you woke up with headaches. 

But FOR GOODNESS SAKE don’t put dodgy electronics under your pillow unless they are certified medical devices prescribed by a registered doctor!!!!
Invalid----This is what I purchased.   Did I buy the wrong one?
