Premium Vibrational Speaker

Works well however the volume at its lowest level could be a tad lower for sensetive ears otherwise a good speaker for what it's intended for.

easy to use very responsive, question can l use sine generator without using the speaker or earphones as l find the constant pitches at whatever freq's put me on edge and l don't think its having the right result ??????

A perfect addition to the PEMF machine, well made, and can also be used as a stand alone blue tooth speaker, like the addition of the volume control, highly recommended.
