I went ahead and put on the red ear socks on my X-Squared today. I have a backordered set of red t-shocks coming as well. I decided that Ruby with X-Metal was a little too common so I wanted to tweak it a bit. One thing I've noticed on the X-Squared that I wish Oakley address is the fact that when the earstems are folded, the tip can scratch the other earstem. See pic below. Kinda wish they did something about that.
