For sale is an Acoustic Revive RR777 Schumann wave generator. Asking price includes shipping to the lower 48. I am not the original owner as I bought this used from another audiophile.
There are some very good reviews of this product out there. However, I will say that I didn't get the results I was hoping for. It could be placement issues or that my room is too big. (Sorry for the upside down picture)
