I just ordered a stenographer headset mic that claims to have a noise cancelling element. A noise-cancelling mic is usually defined as two discrete mic elements place as physically close together as possible, with there outputs 180 degress out of phase with each other. Neat huh? Everything more than a few inches (or less) from the elements cancels itself out. The mlic is oriented so your voice hits one element much more than the other. I imagine it would help cut out 60hz noise as well (exactly like a humbucking guitar pickup). I'll tell you chaps how it works out.
