I don’t understand the downvotes on my comment because it is how it feels like and I didn’t mean it in a bad way. As I said in my longer “review” the S2 feels like the most consumer oriented tuning of the whole 600 lineup at least to me and for people who listen to a wide variety of music like me it’s actually better than the others in this lineup. However for instrumental, acoustic, vocal focused very mid heavy songs I would pick the 660S over the S2 although any song with a slight bass will sound enjoyable on the S2 and this is what I meant by saying Sony/Beats tuning.
