Despite the fact that Bionic Ear is just a toy, the device allows you to clearly hear and record the slightest rustling at a distance of 30 meters and loud speech at a distance of up to 100 meters. At a farther distance, you can try to read lips, using the built-in telescope with 8-fold increase. The device operates on a nine-volt “Krona” type battery, and is sold here for 27 euros.
PS That's just interesting: what will the police say? ')
