Well, they do not work while playing DSD but for everything else they def do...my favorite (the default I believe) is filter 4, The music sounds as it should and has a lot of air around everything. filter 3 is the widest stage but the airiness is very much reduced and brings the mids forward. I can pick up the differences easily using the Audiosense T800's
