The W50 seems like a miss. Whereas, the W60 is pretty brilliant. Despite the W60 being more expensive, it is a no-brainer between the two. YMMV
Yeah. Even accounting for sound signature preferences, the gulf in quality between the W50 and W60 is far greater than what the price tag suggests. In fact, The W40 is the better IEM, IMO. The W50 seems to be the literal dark horse in the lineup.
