I'll post some initial impressions: [headphone still burning in, brain burn in in progress as well]
- Comfort is top notch. Pads are breaking in well and although they seemed a bit small, my ears can tuck in nicely. One of the few headphones that fit me well. Along with the headband it is the best comfort I've experienced yet.
- Bass is excellent, impact is aplenty [depending on genre and song of course] when called for, extension is supreme and texture is mental... definitely trumps my K612 in all aspects, even in impact
- Midtange is neutral, not forward nor recessed, instruments sound very natural and life-like
- Vocals are amazing, no sibilance to speak of [very apparent in comparison with the K612], great presence to vocals
- Highs are extended and airy, with great presence but smoooth, no harshness to speak of, no excessive attention to cymbals and very little fatigue if any
- soundstage height, width and depth is great, it is more intimate than the AKG by a significant margin but the resulting sound is thus much more coherent and enveloping. great holography. The sheer size is on average side of things but this can be a pro as well, because it allows you to connect with the music much easier and "just listen".
- imaging is top notch and so is instrument separation, no problems here whatsoever. Layering is likewise excellent.
- sound is very detailed, easy to pick apart [more so than the AKGs IMO], I imagine there are even more detailed headphones ala HD800 or HE-6, but I am happy with amount I am getting. More details could be detracting or distracting...
- Decay is great, resulting in bass that is fast and accurate [I guess drier] sound, that still has a weight to it
- the sound is very dynamic, incredibly precise and coupled with the intimate, more "in your face" soundstage [compared to AKGs] and great detailing makes for a very involving and enjoyable listen, definitely not laid back, IMO.
- the headphone is very neutral and is in essence genre and track sensitive [meaning it for instance gauges bass differently for genres and tracks]
- even though people label these headphones as light and quick, I disagree, the K612 sound noticeably lighter to me. The 560 has a heavier, more weighty sound in comparison, but I guess still on the lighter side to most, not me.
The few negatives that could possibly be for some is neutral bass [not for me though - I think more bass would negatively affect my experience and mask subtler details].
There's still more and better bass than the K612 provide though... so I don't see myself asking for more.
HD800 lovers will not find that huge soundstage here, IMO but you'll get a much more musical and involving experience in return. In fact, this is the first time in a long time for me when I've just listened to the song without trying to consistently pick it apart... A good sign.
Lastly, the midrange could possibly be a hair more forward? I am just used to the K612 & MA900 forward midrange probably though, so.... I am not sure on this, nothing wrong with the mids per say, they're there and neutral, not recessed. The very detailed highs and bass is certain though.
Not a fan of the cable...
So lastly to confirm, I believe these outperform my former HE-6s setup for me. The HE-6 was brighter and a bit more detailed and refined on my former setup [a-100 + NFB 3.32] but the 560 wins now [Compass2] in tonal balance, musicality and imaging.
I am open to questions
