Okay, been told by the mod that although it's essentially Torchwood, it's okay to crosspost here.
I'm having a go at Jack's earpiece. I thought I had a pair of headphones to mutilate for this purpose, but turns out I may have chucked them away. So... I had a look and what did I find?

Oddly enough... I think they worked!!

I'm going to cover it in silver foil and put the blue tip of the mic in some blue glitter.
