You can use the peech protector, for example, in the car or in a cafe and anywhere else. Its range is 3-20 meters

  • • Ultrasonic noise overwhelms microphones and bugs within 3 meters

  • • Acoustic noise protects you from eavesdropping through a wall, window or third party up to a distance of 20 meters.

  • • You can set different intensity of acoustic noise generation.

  • • It guarantees a perfectly safe meeting.

  • • You can take the speech protector with you anywhere.

The ideal speech protector for all those who very often take part in meetings on the go and want to be sure that no one will eavesdrop on them during the meeting. Portable wiretapping device EO-2 PRO lasts up to 4 hours of operation on battery. It can generate an inaudible ultrasonic noise that overwhelms microphones within 3 meters. But if you want perfect protection, you can also use acoustic noise. The combination of these two protection layers prevents any form of eavesdropping.


Omnidirectional ultrasonic noise generator overwhelms all microphones within 5 meters. It also easily penetrates clothing. Acoustic noise in turn ensures that you cannot be eavesdropped with a stethoscope or laser microphone, or a third person up to a distance 30 meters.

The performance of the EO-1 speech protector is really great. A total of 41 ultrasonic generators with an intensity of 128-132 dB creates a strong ultrasonic barrier for the microphones of modern phones such as the iPhone, Samsung and others, as well as for modern voice recorders and wiretaps.

Ultrasound function

Generates inaudible ultrasonic noise that overwhelms microphones in range of the speech protector. Protects against eavesdropping using microphones. Above all, against bed bugs and the recording of smart phones or watches. The ultrasonic noise generated does not disrupt the meeting in any way, and your partners will not even notice the speech protector.

Easy to use

The EO-2 PRO portable eavesdropper doesn’t need to be configured or installed. You simply turn it on or off with a switch. You can set the noise generation intensity using the rotation level. You can tell if the speech protector is active by the red illuminated inscription of the EO-2 PRO model.

Acoustic noise

It protects against eavesdropping through the wall with a stethoscope microphone, and even prevents eavesdropping through window panes with a laser microphone. Acoustic noise provides an additional level of protection against eavesdropping based on technology other than conventional microphones. It protects, for example, against a third party who would like to eavesdrop on you from afar. Acoustic noise generates different voices, which you can also record into the speech protector. These then overlay the conversation itself- so they are audible to others.

Instructions For Use

The device uses the following three levels of protection:

  • Silent Ultrasound – suppresses high quality voice recorders. Place the EO-2 PRO portable speech protector in the space so that the ultrasonic source (placed in front, under the black fabric) is directed to the risky place where there may be wiretapping. The effectiveness of ultrasound is up to 3 meters without acoustic noise. This mode is turned on using the button on the front panel in the left part. If you hear an acoustic noise when you turn it on, you can adjust it using the rotary volume button located on the front panel in the right corner.

  • Ultrasound and quiet acoustic noise – is the main operating mode, which allows you to act comfortably and protect you against all types of eavesdropping devices. It is turned on using the volume button on the front panels in the right part.

  • Ultrasonic and Silent Acoustic Noise - is the main operating mode that allows you to act comfortably and protects you against all types of eavesdropping devices

  • Ultrasound and loud acoustic noise –maximum protection mode used when you need to fully protect information at the cost of reducing comfort during negotiations. It is turned on using the volume button on the front panels in the right part.

You can record your own voice for using acoustic noise into the speech protector by pressing and holding the volume button located in the right corner of the front panel for about 5 seconds until the red EO-2 PRO sign goes out, the recording mode is started and you can release the volume button. We recommend conversing for at least 5 minutes on a casual topic. The bug speech protector will then use the recording to generate random words, effectively overlaying your conversation. The acoustic noise is unique, you will find it in all our EO speech protector.
