    the link will lead you to the circuit we copied.. we tried it out with only just one input and an output to see if it works. it doesn't work when we input a simple headset microphone on it. but when we take a line in from a player and input it in the circuit, it works rather well. very clear actually.
    please help. we need to find an explanation as to why it doesn't work on a headset microphone.

    Hello,

    What kind of headset mic is it?
    Does it need external power?
