First off, to get that lollipop stick into the bottom of the cone, use a toothpick to poke a hole.
Then you can insert the lollipop stick, pushing into the marshmallow to be sure the stick won't fall out.
Prepare your candy melts (instructions on bag) in the microwave. I use a tall glass measuring cup so there's room to dip. Also, pour some of the black sugar into a small shallow bowl for dipping.
Dip your cone and let the excess drip off.
When the coating starts to dry (don't wait too long), dip the top into the black sugar. This will make your microphone top.
Place the stick into styrofoam to set.
