I second the Sennheisser CX300-II! I have owned a pair since 2009, and they are still going strong. I used them daily for two years, and they still see use at least two days a week. They are the only in-ear earphones I've tried that actually fit my ears - and they fit superbly. Also, the sound is great, and, they have lasted longer than any other headphones/earphones I've ever owned. As mentioned in another thread, I have very bad gadget karma. I tend to break everything I buy, especially consumer electronics. The fact that I've not yet broken these has got to mean something.
