Very good, it fixed the issues I had with the regular D8000 I had, and will for sure be used in the mastering rotation. It has a more intimate sound and fixed the subpar bass and treble performance. It is less “fun” then the D8000 but I did buy these for work. Also much better at high volumes then the regular version. It’s just pretty dang neutral yet with a more enjoyable sound. It might replace my mx4’s in the rotation, but I don’t know yet
