If you listen to electronic, I would suggest the HE-400i over the 560, simply because it has more weight to the bass. After owning the HE-400 for nearly two years now, and having electronic music as my main genre in my library, I can say I have been spoiled in the electronic music department with the HE-400's bass. But imo the HE-400i does a fine job at rendering bomb-ass bass. Not as good as the 400 of course, but pretty damn close actually. Just my 2 cents of course.
