I have read a lot of reviews on these headphones and decided to try them out as one of my first good pair of closed back's. I currently also  own the HD 598 SE.   Low end The low end/sub bass on these are terrific for those who like a good bass but are not bassheads. They have a good umph in the sub bass, are tight well controlled and not bloated. I was very surprised about how good the low end on these were!   Mids The mids are clear but you can tell some vocals are ever so slightly recessed. Very slight V shape but borderline neutral.   ...
