An invisible earpiece is a micro wireless earphone to be put inside your ear. It will let you hear your partner and get necessary information in real time.
    All you need is a cell phone and an assistant (friend or colleague). Right before the event (exam, meeting, presentation etc.) you put a micro earpiece into your ear and hide the microphone under your shirt.

     Both of them are small wireless pieces, therefore are invisible to other people.
    Then you make a call to your partner and enter the auditorium. Now you can talk into your invisible mic and listen to your invisible earpiece. Be tricky and act naturally and you will make it!
     You can choose out of three device modifications:
    • MWE Bluetooth model includes the micro wireless earpiece and transmitter loop with a built-in microphone wirelessly paired to your cell phone.
    • If you cell phone does not support Bluetooth you can use MWE model. It has the same micro wireless earpiece but the transmitter is hard wired to the cell phone through the earphones jack.
    • If the use of cell phone is forbidden you can use your MP3 player instead. You can record the information and then listen to it. In this case you need MWE MP3 model.
