Premium Vibrational Speaker

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.

Speaker is sturdy and well made . It emits the sound into the room . It can be quite loud so have to start at lowest volume .
