I just purchased a pair of Westone UM3X in-ear monitors. I was cringing at spending $320 (best I could find on amazon) for headphones, but since I received them I never want to take them out.

For those of us that work with or use technology a lot during our days, I think there's something to be said about spending a little extra on the part that connects the human to the technology. Connecting these two very different things in a pleasing, comfortable, exciting way is not easy.
