To me it’s always between this and the 650. I don’t own either but I always listen to them every time I went to my usual shop. There are more expensive and exotic cans which does some or many things better but I felt most at home with the 600s and 650s. I stopped drooling at headphones after my HD25 and went for iems after that, but if there’s one more over-ear I wanna add it’s these.
