I've almost always made use of "loudness" buttons when listening quietly. Without that "fullness" in the bass, it just always sounds thin.

I actually wouldn't be surprised.... now that I think of it I'm quite confident.... that I often listen to music louder than necessary pretty often to ensure that I do get that full bass sound!
