from my experience 2-pin is absooolutely unreliable and bull****, is the worst thing in audiio ever. I broke it 5 times only at my K10. so no Noble anymore till they use this old fashion technology, now I use only campfire and westone.
No offence but you seriously broke your K10 pins 5 times? What on earth were you doing with them! I change my cable regularly between a Linum SuperBax and a short Forza AudioWorks Hybrid IEM that I use for my ES100 and I have never had a problem. They pull out and fit in smoothly. I have changed cables probably over 100 times without incident...
