OK, sorry, irrevelant title. BUT DON"T GO AWAY!
Has anyone done this before:
(The microphone I am mentioning is a really cheap mic my mom bought online bargain-priced

)
Have any of you covered your microphone heads (that sphere shaped part) with a noice-cancelling headphone to record?
I find it very useful, especially when I have such a horrid microphone. I mean, this process doesn't necessarily block out noise (I use Audacity for that

), but the sound of the piano on the recording is much less mellow than if I did not use the headphones. It sounds less "novice".
So, have any of you done this before?
