Product Overview

  • The ultrasonic effect on the microphones of recording devices makes it impossible to listen to and record human speech on voice recorders and portable devices, even with ultra-sensitive microphones.
  • Functional as a charging device. In addition to the audio blocking function, the defeater can be used as a normal power bank to charge 5 volt USB devices, phones, tablets, smartphones.
  • Autonomous operation of up to 1 hour allows using the defeater where there is no 220V connection available.
  • The unit is directional, this means that the speakers that emit the ultrasonic frequency need to be facing the area you are trying to block out.
  • Quiet operation. The ultrasonic noise generated by the defeater is invisible to the interlocutor.

Availability: This item is built to order so please allow an extra 2-4 weeks for shipping and processing times.

    This item works just like the demo videos show. I used my phone to record a test video and couldnt hear myself talking at all!
