Like, in the ballpark of +/-2 dB response all the way through the useful range of these sweet 40mm drivers.the holy grail.
A reference quality listening experience was my goal, and I believe I've attained it. IMO, they take this already excellent headphone up to the next level in terms of neutrality, bass impact, and top-end clarity.
I've spent the past month refining these custom EQ settings for the Sennheiser HD 598, and I hope they will give you all as much enjoyment as they now give me.
