GSM pen for SIM card with spy earpiece - inconspicuous eavesdropping and communication via mobile phone with another person. Each of us knows situations in life when you would appreciate someone advising you, helping you in a difficult situation without anyone noticing.  

It is intended for presenters, TV and radio hosts, speakers, for discreet communication with your team and for other situations. We certainly do not support its misuse for cheating in exams, at school, etc. The improved model of the spy earpiece is a revolutionary device that will allow you to connect with someone remotely through your mobile phone, but without anyone knowing about it. Activating the device is very simple. Insert the SIM card into the GSM pen and turn on the device.

spy in-ear hearing helper for students for exams

Place the pen near the earpiece to pair the transmitter (pen) with the earpiece and insert the mini earpiece into the ear. A signal is transmitted wirelessly to the earpiece, where the signal is converted into voice. The entire device is wireless and thus absolutely unobtrusive.  A sensitive microphone is used for communication, which is built directly into the pen. After calling the SIM card, the device automatically accepts the call and you can start communication.

This spy pen also serves as a full-featured writing pen, thus increasing its stealth. The earpiece is powered by one miniature button cell battery. You simply insert the earphone into the ear canal of your ear. A translucent hook is attached to the earpiece, with which you can just as easily remove the earpiece from your ear. For even easier handling of the earpiece, we offer magnetic tweezers in our e-shop. The pen has a built-in rechargeable battery with a capacity of 300mAh, which is recharged using a micro USB cable.

I used it in the oral exam. A friend heard everything clearly and could advise me - a really excellent gadget. I recommend it to everyone who wants to be sure about the exams.
