Product Description
The ultrasonic defeater comes with two speakers. One speaker is the defeater which will emit the ultrasonic frequency. The second speaker is a mock speaker, it does have a USB port if you would like to put music on a flash drive and play music from the unit. The unit is directional so works best facing the area you are concerned with.
This device is not a jammer. This unit only will only interfere with microphones.

Amazing Product
Who knew that a product like this existed? It makes a sound that we cannot hear but the microphone does. That sound makes the microphone go haywire and not able to record voices. Looks like computer speakers. Some younger people can her this but most over 20 something cannot.
