    Thanks Richard Crowley and Laurence Payne for your explanations!
    A Sony ECM-T6 microphone and another desk-top microphone don't hum! A
    new Koss sb/45 headset and Philips SBC HM300 headset hum from their
    microphones.
    How to make Koss sb/45 headset microphone work?
    Best regards,

    The speakers are only disconnected from the audio source, the "wall
    wart" is still powering the speakers amplifier. Try turning the volume
    knob down or unplug the speakers little power supply.

    IIRC, any Sony mic with the prefix ECM is a quality product -
    although even Sony is not what it once was, sadly. That used to
    be a prefix for their professional mic line, but that may have
    changed.

    Nothing which is NOW called professional IS - if it says
    "professional" or worse, "professional quality", DON'T buy it.
    If it's professional, you'll know it by where it is sold and how
    much it costs. All "computer" microphones, headphones, and
    speakers are TRASH and always will be.

    Koss was a very good brand 35 years ago. It is trash now. The
    name was bought by some jerks - like it has happened with MANY
    formerly good brands - and now they sell junk with a formerly-
    good brand name on it. Put it in the garbage where it belongs.

    If you want a decent headset/mic combo that will work properly
    and does not have wires inside touching where they shouldn't
    etc., you will need to spend a fair bit of money. I am talking
    Sennheiser, Beyer, etc. Hundreds of dollars. NOT made in China
    shit.

    Much cheaper to get a gooseneck desk stand for your mic and use
    the 2 separate devices. Easier on your head physically, as well,
    and doesn't get in the way of enjoying your coffee or vodka. (Or
    both together.)

    The speakers are in a headset. There are no other speakers. A "wall
    wart" is not powering a headset.
    Why does the hum appear from a headset microphone only, not from a
    separate microphone?

    Thanks thanatoid for your suggestion!
    A table stand microphone requires to keep a mouth in one place, 2
    centimetres from the microphone all the time to catch minimum
    background noise. A headset microphone does not require.
    Why does the hum appear from a headset microphone only, not from a
    separate even small and cheap microphone?
    Best regards,
    Dima

    OK but this is my LAST reply.

    A GOOD unidirectional microphone (like possibly your Sony) does
    NOT require anything like you describe. 5-10 cm is more than
    sufficient.

    A gooseneck can be moved VERY easily, the best way is to screw a
    flange mount directly onto the desk (they're about $3) and screw
    on a gooseneck of your preferred length (with a mic clip) on the
    end on to the flange.

    A good gooseneck is very stable, and $25 is certainly better
    than $200 for a medium-good headset, IMHO. But maybe you're very
    rich. I have heard things about the Russian Mafia ;-)

    The reason your headsets HUM is because they are CRAP and wires
    are not properly isolated from each other. Borrow a $350 one
    from a radio station or a DJ or something and you will find out.

    ANY set of walkman/iPod head/earphones and a decent
    unidirectional mic is the most cost-effective chat (or whatever)
    setup.

    If you don't like goosenecks and don't want hum, get a $400
    Sennheiser headset and a $30 adapter so you can use it with your
    sound card.

    Over and out.

    Regards
    t.

    Dear thanatoid,
    Sony ECM-T6 microphone does not hum!
    New headset Koss sb/45 and headset Philips SBC HD300 hum from their
    microphones!
    Why do headsets hum? They work well on another computer.
    Best regards,
    Dima

    The confusion comes from the misuse of the term "speaker". The sound
    producing components in a headset are called "headphones" or "earphones"
    not "speakers", the condition I described applies to powered speakers
    not headphones or earphones.

    The ferther a mouth from a microphone the smaller a difference in
    volume between a sound from mouth and a background noise.

    Hello!
    The headsets hum from their microphones even through another sound
    card Creative SB 16, although they do not hum on another computer.
    How to prevent the hum?
    Best regards,
    Dima

  13. Aren't we over this discussion, it really isn't one for a pro audio group.
    Please stop cross posting.

  14. Maybe is just that that's all you can expect from a $50 gamer
    soundcard...

    No, the soundcard works well with a separate (not in a headset)
    microphone. Another card works the same.

    Hello!
    Microphones with a battery do not hum. Why?
    How to make microphones without a battery not hum?
    Best regards,

    Because the power is not being supplied by your PC?
    By making sure the card & microphone are fully compatable & that
    you're not pushing your PC power supply to the limit as they tend to
    get a little unstable if you continually do.

    Because the battery is independent of the mains power.

    That confirms that the problem is coming from the mains-
    derived microphone power coming through the sound card.
    Replace the sound card with one that works properly.
    (Or just continue to use the battery.)

    Thanks kráftéé for your answer!
    There are no microphone requirements on the Creative site for SB live
    or 16.
    Who to make sure that I'm not pushing my PC power supply to the limit?
    Best regards,
