Following this with interest as I am a IEM whore. I have bought and tried many pairs over the years and have settled on Shure 530's as my normal listening cans and ER-6i's for riding and working out. I love the Er-6i's and will eventually need a replacement.
Had anyone asked Putts for his suggestions on a replacement? He is in Vendors and owns Headphone.com.
