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!!!!

Homeopathy and audiophilia. What a pairing!!!

I bit. Four cheap ones are coming to try. If they fail in audio but make my wife sleep better it's still a win. I have a high confidence level though, based only on those who have actually heard them in use. $45 del'd/4 so no worries on my end if no results. If one or two are enough I have spares. I remain open-minded on this.

Thanks to all who have tried them and reported back, favorably or not. Their information is of value. As for the rest (with lots of opinions and facts or non-facts), I'm unsure what dog you have in this fight over whether they work. Seems you won't know either way if you don't ever hear one. And we sure have worn out the track with repeated laps...

I am interested if anyone has any experience with the SRs that generate a square wave versus a sine wave. I am wondering about the possible differences between the two based on some comments on 'pain' with square wave resonators. Thoughts based on real experiences are what I'm interested in. Possibly educated theories could apply. Thanks much!

Wondering why anyone would try to produce a square wave instead of a sine wave. Makes no sense to me. Perhaps someone more learned can chime in.

Sad to hear it musicaddict, I wish you had spent that money on music. This is the way the pharmaceutical manufacturers get away with it. They know a product does not work but they figure if they can get a lot of people to spend a little money they can make out big time. Then they stick the same pills in another bottle, tack on a name and an indication and make another fortune on the same product.

Never trust what other people hear. Hearing is way too plastic and open to psychological interpretation making any comment indecipherable.
