I'd say FOTM ("for the money" in case you're a newbie), the Shure SE215 is probably one of the best choices. If you need isolation, the Etymotic ER6i, MC5, or HF5 would be your best bet, although the bass is somewhat anemic. The MC5 will have better bass than most Etys, but it still leaves something to be desired. The SE215 has good isolation as well, especially with foamies and the bass response (since it's a dynamic driver) will probably fit the bill.
How are you thinking that For The Money works out to FOTM? You're missing the O. FOTM is Flavor Of The Month (i.e. the overhyped new toy that gets exaggerated praise).
