I just bought a set of e3s from eCost for about $110. The difference is amazing. I can hear detail I had never heard before. With the foam inserts, sound isolation is near complete. With these things in, I am effectively deaf to the outside world. I have pair of the three-flange silicone inserts on order, as I have heard good things about these, and they don't need to be replaced as frequently as the foam. I bought a set of ten foam inserts, too, just in case.
