Microphone Differences Found Between Wi-Fi and 3G iPad 2 Models

iPad 2 microphones: 3G (top) vs. Wi-Fi (bottom)

iLounge found out that the microphones on Wi-Fi and 3G models of iPad 2 have differences in quality of sound.  The best sound quality was demonstrated by the Wi-Fi model.  It might be caused by the fact that the mic on the Wi-Fi model is on an aluminum surface while on 3G is on the black plastic. The differences are most noticeable when the iPad is held facing the user, for example, when using FaceTime or other video applications.

Perhaps due to this change in materials, the Wi-Fi model offers markedly cleaner audio than that of the 3G, which sounds slightly muffled and echo-prone as a result. Curiously, we found the GSM 3G model's audio to be slightly preferable to that of the CDMA model, which seemed to suffer the issues more severely.

In the previous model of iPad the microphone located next to the headphone jack on the top edge but in iPad 2 Apple decided to place it in the center. Though, it seems that such change does Apple more harm than good.
