Discreet and at the same time very effective speech protectors. The design of the TOWERS does not interfere with the meeting as it looks like a luxury speakers. However, it effectively protects you from leaking information. It combines ultrasonic and acoustic noise – protecting up to a range of 7-50 metres. Now your conversation stays private.

  • • Ultrasonic noise effectively protects against eavesdropping, but at the same time does not interfere with the meeting, it is completely discreet.

  • • Ultrasonic noise reliably overwhelms microphones at a range of up to 7 meters, protecting you from eavesdropping and bugs.

  • • Acoustic noise generator can effectively disrupt your conversation. An attacker will not be able to make a quality recording using a stethoscope or laser eavesdropping device.

  • • The speech protector can generate your own voice as acoustic noise.

  • • You can set the intensities and modes of wiretapping.

  • • It is completely discreet and looks like a classic speaker.

TOWERS is the successor to the EO-3 MAX, one of our best-selling products. Compared to its predecessor, it has improved ultrasound software, processor and consists of 4 pcs. You can choose the appearance of your product from our color catalog. There is also an app available for TOWERS that is compatible with both iOS and Android.


A really discreet TOWERS speech protector in the form of a large speaker. Thanks to this masking, no one will suspect that it is a wiretapping device and your meetings will go on completely undisturbed. The TOWERS speech protector protects up to a distance of 7-50 meters i.e. the furthest of our speech protectors. Combines ultrasonic noise that overwhelms nearby bugging microphones along with acoustic noise. This combination brings the state-of-the-art and best possible eavesdropping protection. Another advantage is that you can record your own voice into the acoustic noise, which the speech protector will then generate to drown out your conversation.

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

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.

Acoustic noise

Acoustic noise protects especially against laser and stethoscope microphone. Acoustic noise thus easily protects you from eavesdropping through a window pane, through a wall, or by a third person from a distance. In contrast to ultrasonic noise, acoustic noise is audible to the normal ear. It works by overlaying your conversation by randomly generating words. You can even record your own voice into the speech protector as an acoustic noise.
