I bought the Shure E3C about 9 months ago and love it. Once while on a long plane trip, the right phone went dead. I contacted Shure when I got back and sent it in for replacement. A few days later I received a new, retail packaged E3C. ^ ^

I love the quality. Bass could be a little more resonant, but it cancels out noice very well, so you are able to feel it well enough. I love the quality in the mid-high range though. And they are very light and very portable. Comfortable enough (for me) to sleep in. I don't like how the cords are designed to go behind your ear and down your back, so I usually just wrap the cord around my ear and let the cable go down to my front, to my iPod, laptop, or whatever. I got the E3Cs online for about $117 9 months ago and it was one of the best purchases I've ever made.
