    Hello there,
    I want to connect the OTTO V4-10434-S model headset I own to the ICOM 7300 HF radio. But I need your technical knowledge about the Microphone element.
    Electret condenser is my microphone element?
    or
    Is it a dimanic microphone and what is its impedance?

    According to this information, I will make a connection adapter for the ICOM 7300.

    tnx.

    Part number C101922 appears to be correct, yet you may need to drill down at this site to confirm your product: https://www.otto-comm.com/-/media/Common/manuals/manual804014revf.ashx
    It also seems that 9.6 VDC .24A may be involved per the ATEX specs document. Element for V4000 series 19db, 24db noise-cancelling headset (overall system). There is also a 3db element, part number is C816028.
    e-mail is shown as : info@ottoexellance.com yet phone 1-(847)-428-7171 may get more results ( though also a phone bill... ).
    The HT-750 and other radios which this may connect to typically would have internal electret elements, yet since the headset is ATEX rated- and includes o-rings, etc.- other types may apply. Dynamic is a remote ( no pun intended ) possibility.
