Studio Beats Wireless Hinge Pins won't cooperate

I have Studio wireless beats. I was trying to replace the headband, and as I was doing that the hinge pins and the "band" , metal piece popped out of both the left and right side. I know obviously where the pins go, but the band doesn't seem to budge to fit on the pins. Or am I doing it wrong? Please a tutorial or a picture of how it is supposed to go. Thanks
