应该不至于,“The revised coil of the S2, for instance, now matches the 300-ohm impedance of the legendary HD 600 & HD 650.”
框架还是660的,宣传这么提到了应该是线圈改进了,至于是不是向两个大哥靠拢,不太好说
"It’s the same team of engineers behind it as the last few years — Jermo Koehnke’s first project as lead designer was HD560S, so it’s not shocking they’re now trying to replicate that success in the 600 series.
He mentioned in an interview that people would send him hate mail if he touched the 600 or 650, so him modifying 660S was probably the most natural option. I hope they nailed it this time."
