I asked which fw people like more not which one is right. Just curious what people think about it. As i always use bassy iems, wm1a suits me well in terms of bass quantity. What 3.02 lacks for me personally is musicality. I found it too clinical for my taste. I need to try 3.01 though. And yes you are right about iem choice affecting fw preference , i would also add music genre to that.
