Shure E2 versus Bose in ear monitors? - shure in ear monitors

I am the singer in a rock band. I'm looking for ear monitors that are used, both on stage and my iPod. I also support a lifting of the sound (either actively or passively) in the ambient noise during the flight. I can not pay too much. Shure E2, Bose is about the same price. I recommend it? further proposals for similar or like EMI and less expensive?
