So, I got to hear the 1570 for a decent amount of time. I think they are good, and their main competitor has to be the lcd2 classic with the sound they are going for imo. I think the 2 classic is more bass focused, and the m1570 is a bit actually like lower mid focused. They are both darker but the lcd2 c is a bit darker. The bass is good, but I prefer the 2 classic for it’s bass response. I actually like the midrange more on the m1570, but it has some issues with some shout and some peaks. Fairly wide sounding too, but nothing that blew me away with layering or spatial accuracy. The imaging was better than I thought and I think it’s very interesting that it does better than the 2 classic in that regard. Overall I think that it’s a good competitor to the 2 classic or other headphones in it’s range for a fun planar, but it didn’t blow me away tbh. I think it’s worth the price, but I don’t think it has the bang for the buck as the m570
