What is a spy earpiece?

A miniatural assembly that enters in the ear canal and consists of an electronic circuit as a receiver and a speaker wich plays the sound.
The use of the micro spy earpiece is to receive secrete information.

Depending on the type of receiver a micro spy earpiece can be inductive or FM (modulated frequency).


spy-earpiece-inductive  The inductive micro spy earpiece is able to receive an audio frequency signal from a small distance of 20-50 cm. This type of spy earpiece can be used only with an intermediary induction accessory placed near the user or on his body.

 


FM spy earpiece

 The FM spy earpiece is able to receive a signal from a very big distance, of 200 - 1000 meters, from a transceiver. This kind of earpiece doesn't need any intermediary accessories on your body, in order to listen to your partner.
