After some more time with the W60 I can safely say it blows my W3 out of the water in every way. I previously thought that the W60 mids were overly smooth compared to the W3, and they still are smoother, but I now realise that is how the mids are meant to be. When i switched back to the W3 after a week with W60 i realised just how lifelike the W60 mids were, both male and female voices sound faultless, the W3 could not compete at all, bass through to treble the W3 sounded like a second rate iem compared to the W60.
I am pleased to say that I now have zero complaints about the W60 and am very happy i got it. I'm actually addicted to its sound and don't know if I could live without it! It truly boggles my mind that a week ago i could prefer any aspect of the W3 over the W60, actually kinda makes me realise how fallible and susceptible the mind can be.
