Working in an open space where everyone around you is exposed to your phone conversations is an irritating experience for both parties. Privacy is paramount to most of us when we want to protect certain information from eavesdropping ears. Babble is a voice privacy device that makes it possible for people to have confidential phone conversations at work in a voice that is indecipherable. This gizmo is compatible with any standard power outlet, and makes phone conversations sound like a hum to the human ear. It blends your voice with random versions of your voice. The unit comes with a $395 pricetag. Product Page
