Don's probably right -- I ordered the MH2 microphone together with the KSB2 kit, and I think the jumpers were indeed packaged with the microphone.

You can use the two-pin "computer" jumpers if you are just doing a direct 1:1 jumpering of the configuration header. If you are using a different type of microphone, here is the computer connector hack I was thinking of:
