    Not long time ago wireless headphones BINGLE B616 has become available on Aliexpress. These headphones use FM radio channel to transmit signal. Time proved subject wireless headset can be used succesfully with metal detectors. Here you some pics of headphones BINGLE B616 adapted to metal detectors:

    BINGLE B616 operates 2 channels:
    1. Channel A: 109 MHz
    2. Channel B: 110 MHz

    These headphones do not interfere with metal detectors at all. Maximum effective distance headphones operate in is 50 meters and there is no sound delay.

    In order to prevent/minimize audio distortion 2x100 Ohm resistors should be added to plate. Microphone should be removed from plate as well. By fact, microphone was not operational in 2 sets of headphones, so there is no point to keep it.

    There is no sound distortion with AKA detectors even if no additional resistors are added, in case of Fisher F75 additional resistors is must have.
