The HDJ-2000 passes the most important of tests for DJ headphones with ease: It does not distort at top volumes. Even at maximum, unsafe listening levels on tracks with challenging deep bass content, like the Knife's "Silent Shout," the HDJ-200 delivers clean audio. Its bass response is comparable to that of the HDJ-1500, but of course this requires first that you get a secure fit on the loose-feeling HDJ-1500—the HDJ 2000 fits snugly and comfortably the first time and requires little adjustment, thus ensuring more consistent bass response, as well as more consistent ear-to-ear performance.
