I may have missed something but why is everyone so sure there's only one mic tip? The first "rendering" that appeared showed a mic tip on the left. The second "real" picture showed an actual helmet from the right side with no VISIBLE mic tip, but if you look in the background on the left side of the photo there's another helmet behind it and it looks the same on the right side. No VISIBLE mic tip. Are we sure these two images aren't just different because one was a concept and that they moved the mic tips further down below the seam to more closely replicate the older helmets? There are other differences from the render to the real photo as well. To me it looks like the mic tips were just positioned further down and aren't visible in the later image.
For one, the section circled in red is much thicker in the real helmet.
Look at the area circled in green. Left area...NO Mic Tip.
