GSM Intercom: GSM transmitter and RF spy in-ear receiver

Description

GSM Intercom (GSM transmitter and RF earpiece) for infinite discreet communication

The GSM transmitter has automatic answer and 20 meters range to the RF earpiece!

This set replaces a bluetooth and a cellphone for the most discreet, infinite range communication.

What is it for:

The user can have a phone conversation using this set: the RF earpiece in your ear and the GSM transmitter near or on a pocket.

How it works:
The GSM transmitter has auto-answer function (for one selected phone number – it will ignore all the other incoming phone calls) and it transmits to the RF earpiece in the ear (the smallest one MRF400-B) from a distance of about 20 meters.
The GSM transmitter, also has a sensitive microphone incorporated, allowing you to speak back to your partner (two-way communication).
The battery of the GSM transmitter is rechargeable and it holds about 5 hours.
