The Bionic Ear headphone is a powerful spy gadget which can let you eavesdrop on someone talking within 100 meter away from you. The device does not only collect sounds, it also lets you see far objects at up to 8x magnification, thanks to the built-in monocular.
The device can let you hear faint sounds from the distance of 20-30 meters and loud noises up to 100 meters using the included stereo headphones. It also has a built-in recorder which can record sounds for 12 seconds at a time, and repeatedly listen to it when you have more free time.
The device can also be adjusted or set on one particular frequency for clarity via a turning knob. Of course, it’s best used by the detectives, but it can be used by nature lovers as well to collect bird’s sounds or perhaps “cries of the mother nature”.
