Not sure of your budget, but Sennheiser IE8 is pretty dang good. It puts out very deep and tight bass while still able to maintain good balance with the mids and highs. Shure SE530 is also a very good contender.

You might want to pass on etymotics and phonaks, because they put out very light (albeit tight) bass. Awesome for classical, acoustic, etc, but not bass-heavy genres.
