Spy listening device - listening through the wall - 3rd generation

Spy listening device - listening through the wall of the 3rd generation with 13K sound amplification + built-in 100mAh battery + headphones. The battery is charged using a USB charging cable (included in the package). A through-the-wall listening device is a compact device that allows you to listen to conversations in the next room. The listening cover is equipped with a highly sensitive microphone that can resemble a medical stethoscope/phonendoscope.

Inside this microphone is a needle that picks up sounds resonating through walls, doors, columns or pipes. The device allows listening to sound through walls made of concrete, steel, wood, iron, glass or brick.

The listening device allows you to hear through any solid surface such as concrete walls, drywall and pipes. This device can also be used to locate people trapped in the rubble of a collapsed building, in elevator shafts, underground, or in other emergency situations. Charge the device using the supplied USB cable before use. Subsequent use of the listening device through the wall is already very simple. Connect the supplied headphones to the device and place the device on the wall. Turn the knob to turn on the monitoring and at the same time turn the knob again to set the desired volume.
