The shields for the two are the same, and you're supposed to upload an image while you order, but you can do it afterwards if you want too, as long as they haven't shipped.
The boom mic doesn't come with the current pre-order, they ran out with the last run! They probably won't have new ones for a few weeks...dunno how much they'll cost though.
The headphone does indeed have two inputs. The boom mic's cable is also an audio cable though - it has the same TRRS plug the standard mic cable does, with both voice and mic with the same plug. You'll need a splitter if the source has two ports for
Thanks. I should buy lp2 shields for m100. But could you explain what image I need to download? Is it my simple image which I found or I need to download image in photoshop form whicn taken from v-moda site? I was read that some people send their images to firstname.lastname@example.org after ordering.
