bluetooth handsfree microphones

Hi all, just wondering if the outputs would be different from these two microphones and if anyone has already been down this route, they are both designed to fit in the internal overhead lamp cluster of probably all vags. The oem is German made, by a company with the name Paragon.... 3B0 035 711 B, the other made in China 3BD 035 711 here's a forum link which many of you will have seen before....http://forums.vwvortex.com/showthread.php?6028806-OEM-microphone-wiring-help-needed

Thanks for your help.
