From what I've seen it looks like the back gimbal holes are more susceptible to cracking than the front ones. The other two posts appear to have cracks only in the back. My pair have also cracked here.From what I've seen it looks like the back gimbal holes are more susceptible to cracking than the front ones.

In other news, I agree that people with large/tall heads will have a bit of trouble with these cans. My head is tall and skinny and to even get the ear-pads to line up with my ears properly I have to adjust the headband past the last notch, so that the little sliders are actually bottomed out. Because of this the headband puts a lot of pressure on a single point on the top of my head. Other cans I have also sometimes run out of room (for example my HD800's are set on the second to last notch to fit me correctly), but these are the first cans that almost don't fit me.
It's a shame because I love the sound of them so much... I'm hoping the headband will break in a bit and they'll be more comfortable the more I wear them.
As far as the connectors go, my left connector is definitely a lot looser than the right one, but it doesn't drop out unless I intentionally mess with it to get it to do so, but we'll see if this becomes more of a problem in the future.
