K3YSNuForce EDC IEM are going to be waaaaay better then these, these look like the Kineira BD005, not bad, but won't last for long. The NuForce, on the other hand is a whole different story, first of, NuForce is Optmo and they are (IF I am not wrong) designed in Japan, I have two of the NuForce as how much I loved the first pair I got. If you do go with a pair of NuForce, a portable amp would be a good idea, something like the nx1s.
