Make sure the firmware is updated. There was an update not TOO long ago that in the build notes, it said it improved call quality. Also check the incoming call volume.. Other than that, I'm not sure.
Edit: On my droid, I don't have a cover on the top portion, just the bottom. (I always sit it down with the screen facing up, so the use for a top cover seemed pointless.) I do have a nice screen protection film on there though! So... depending on the type of cover you have on the top, it might be putting the ear-speaker too far from your ear, making it hard to hear / muffled sounding.
