But I can tell you that what I'm hearing now in the spatial placement/resolution/detail makes it very worthwhile to work these things out.
And don't worry one bit about what others say of your being negative and dismissive of the 'greatest new thing'.
That's what these boards are for.
prscustom: I had the E500 twice, and sold it both times. The sound signature wasn't for me, so it's possible you just prefer the E500. But I would suggest you listen to nothing else but the W3 for a while - and THEN go back to the Shures. I know it's quite popular to go back and forth between earphones to test certain songs, but I only do that after I've listened exclusively to the new pair for a while. I like to get used to the new sound signature first. Give the W3 more time, then go back... and see what you think
