A skin coloured spy earpiece from a Russian vendor called Spytec allows individuals to secretly talk to their counterparts in situations where you cannot have open conversations.
The device requires two phones - one of which must be a cellular one. The device consists of a transmitter which is connected to the cellphone, a small receiver placed in the ear, and a microphone. The receiver receives signals through the transmitter, which works with all kinds of cellphones. You can see the receiver's size when compared to the coins.
