Nope. I actually tested the ossicle out haha. Cable is thicker than the plug. The plug housing is about as long as the plug and 3x the diameter. The outside part that someone can see when it's in the ear is flat except where it tapers in at the bottom a bit and the edges are a bit rounded. It's glossy black plastic that is reflective and no logo.
To be honest, except the most exact proportions, my rendering is reasonably accurate so if someone had seen it before, they would probably know off the bat.
Thanks for taking a shot!
