I found a really good song for you to really hear the difference between HD600/HD650/HD58X soundstage intimacy versus HD 560S, Sway by Cuebrick

About 10 seconds in to around 45 seconds in, where she is singing ever so gently "sway with me" etc, you can hear how condensed/congested it sounds on HD58X - ruining this particular part of the song, and swap and listen to same part again with HD 560 S, night and day difference. you literally want to sway with her, this is the way that song was meant to sound, and it is seductive on the HD 560 S. absolutely beautiful... ugh that is so good, you only need to listen to that 10-45 second beginning of the song to really see what I mean. its night and day better than HD58X for songs like this one. even the intimacy of her voice is better on HD 560 S for this particular song. and usually I favor 58X intimacy.
comfort 10/10
fatigue 10/10 (hd58x wears me out after an hr or so, but these i can easily see myself wearing and listening for 14 hour sessions)
I would call this headphone absolutely relaxing, heavenly, like caramel being poured onto silk cloth...
