That's to allow the PlainTalk to draw power from the port, without the
port zapping any "normal" length plugs used with it. This power is needed
to let the PlainTalk mic generate a line-level signal.

The old mic only puts out mic-level output. You need an amplifier or a
powered mic to get a line-level signal to send into the Mac.
