Audio Nullifier Pro

Price: $2,250.00

Protect your conversations against all kinds of eavesdropping!


A top-of-the-line protection system. Create powerful audio interference against multiple listening devices. Compared to our Audio Nullifier the Audio Nullifier Pro provides an even higher level of protection against eavesdropping.


Don’t Be a Victim of Electronic Harassment!




The generated audio interference cannot be cleared by any noise clearance methods; therefore, neither a listening device nor recorder is able to pick up conversations. The included headset allows users to hear each other with crystal clear quality. The multi-voltage unit is supplied in a sturdy carrying case and features an internal rechargeable battery that will last 2-4 hours.


Not all listening devices can be detected by existing methods. The Audio Nullifier Pro is a unique system for providing protection of human’s speech.


Most of these devices cannot be detected by conventional methods; Remote controlled radio microphones, wired microphones, passive resonators, miniature voice recorders. Even a modern cellular phone may contain a digital voice recorder; this means that any phone lying on the desktop could be used by an adversary to record a conversation. Therefore it is extremely important to have a reliable device protecting private conversations. The concept of this device is based on generating audio interference produced simultaneously with a human’s speech. The volume of this interference is higher than a person’s voice; neither listening device nor recorders  are able to pick it up.



Protects against all known methods of listening, including all types of radio microphones, stethoscopes, voice recorders, passive resonators, wired microphones, etc.

Compared to our Audio Nullifier the Audio Nullifier Pro provides an even higher level of protection against eavesdropping.
