Thank you guys. Your feedback helped me to make the decision, I just bought the red CMK500i from cdjapan, will post my impressions as soon as I get them. 

Hey guys,   I've just read the whole thread and I was wondering if you could give me some advice. I'm planning to get some new IEMs with iPhone controls, my budget is $150 . I was just about to buy the shure se215 plus the iphone cable, but after reading this thread, I'm not sure anymore...
