Don't bother getting the Bose in-ears. I think they're on par with earphones half that price. They just sorta sit on the outer bowl of your ear, so there really isn't any noise isolation like the Shures or the Etymotics. And for the price, I would step up to the E3s over the E2s. Even to an untrained ear, the difference is enough. But unless you are an audiophile, the E3s are more than sufficient.
