Good, but its poor compared to iPhone5 or 4S

When starting Facetime for Mac, the MacBook Airs microphone setting is getting very low. And the counter person can hardly hear my voice. Microphone setting for "Facetime for Mac" needs to be improved. So, if you already uses iPhone5/4Ss facetime, you will definitely be disappointed this point.

But, on a positive side, you can place your Mac on anywhere without holding it by your hand.
