Hiya! I've had my 560 v4's since I'd say earlier this year? Eventually I messed up while trying to change the pads and idk how but I poked a small hole in the membrane of one of the drivers. Recently I got myself another pair and I missed it. Even though I have a Focal Elex and HD6XX, I still have a personal preference for this headphone. I even like it over the Sundara. Imo the Sundara has a nice default tuning sound, but after some brain burn-in the 560 v4 opens up and you start to notice certain things that make it slightly better than the Sundara (in certain areas), like just the overall sense of depth and the soundstage. As I mentioned before, Sundara has a nice default tuning but it also sounds a bit more like a wall of sound. Shallower sense of depth and soundstage compared to the he560 v4. Also live recordings on this headphone sound extraordinary! Like Casiopea's live albums, they sound almost exactly how they would if I were there in the crowd with others.
Just wanted to add in my opinions about the 560 v4 and gush a bit. Also I do have one question. I think I've seen about one post about it but, how is pad swapping on the 560 v4? Anyone else have experience with it? Do the velour pads make them sound better in certain ways? Or is it primarily preference and the default pads are just fine?
