I was really happy to get to try this Schumann resonator out, I've read a lot about them over the years and always wondered whether they do as promised. Although I can’t comment on the last point, what I can say is that this thing works in regards to operation. First of all, I'm really grateful to previous reviewers because unfortunately this gadget arrives with zero instructions and I didn't have a clue how to bring it to life. Fortunately, after checking back on this page I discovered that all I needed was a USB cable and you are good to go. I switch mine on when I go to bed at night and it's very easy to use. What I particularly like is the no-frills design of this thing, it reminds me of some gizmo from the 80s or something out of the Back To The Future DeLorean. Whether it has any positive long-term effects, who knows? But I will absolutely continue to use it!

Make sure you do the proper research of these Schumann wave generators before purchasing. For improving overall well being and protection of EMF that we are constantly being bombarded with. This wave generator does not come with instructions and not even a QR code. It also doesn't come with a power cable and you will need a USB-C cable. The power source needed is just 5V. There is no power button on this wave generator, so once you connect the USB cable, it powers on and starts emitting 7.83Hz, the Schumann resonance. There is a switch on top of the display allows you to turn off the backlighting and you can set your custom frequency using the 13 button keypad on the bottom right. This wave generator also has a headphone out jack so you can listen to the frequency set. However as mentioned, headphones aren't a requirement as this is emitting the set frequency as EMF. In terms of whether it works or not, I can't say without longer term use. I place it on my desk as a way to block or shield myself EMF from electronics devices and hopefully to provide more calmness and relaxation.

The generator lacks instructions, descriptions, a theory of operation, or circuit diagrams. It arrives as a circuit board without a case, but it does have small plastic feet.Using an oscilloscope, I can confirm that it generates a 0.1 Hz square waveform. It also offers a sinusoidal wave at the rectangular radiator and a standard headphone jack. Additionally, there’s a terminal block exposing additional outputs as a square wave, an inverted square wave, and a sinusoidal wave.As soon as USB C power is connected to the board, the Schumann frequency of 7.83 Hz is loaded and operational, as there’s no on/off switch. However, there are limitations. The sinusoidal waves appear as stair steps that become coarser as the frequency increases. Anything beyond 10,000 Hz exhibits an increasing error. For instance, if 10,0001 Hz is input, the generator outputs 10,036.49 Hz. The same issue occurs with decimal points at even lower frequencies, such as 528 Hz, which is rendered as 528.54 Hz.

Was very interested in this unit. Appeared to be well built and when received it was. However, it traveled from overseas and arrived with a cracked circuit board. On power up it lighted up but the connections that were broken render it inoperative. Left a msg with the supplier and awaiting feedback on what to do. It also did not come with any instructions on how to use it. No paperwork at all. Hoping for a resoulution soon since I think these devices really work.
