Kind of true, if you want something that would sound super smooth and pleasant to listening to, then there's nothing better than the W60 (especially in balanced mode), they will even make low resolution MP3 files sound smooth and listenable. If you want something more aggressive and punchy, definitely the SE846. Otherwise the Noble Kaiser 10 is another good alternative, smoother than the SE846 but more aggressive than the W60, one of the most accurate sounding IEMs around. For some reason, I cannot stand the Pro 50, they just sound totally wrong and unappealing to me, can't listening to them for more than a few minutes, the bass is just too boomy and muddy for my taste.
