Just thought I'd throw this out to a wider audience than the westone 4 thread (thanks to those that replied there though!).
Right I've narrowed it down to either the um3x the w3 OR the w4. Thing is they all do things but none of them in one package. Sounds like the um3x would fit me better, the w4 easier to live with day to day whilst the 3 has the more "fun" sound. As a comparison the bass on the monster turbines I had I found gave me a headache, and found the westone 2 a little bass light for my taste. So would that mean taking off the w3 from the list. It would be for everyday use from out of an ipod touch 3rd gen listening mainly to rock and metal.
Now I can see why I ended up at the westone 2's in the first place, I may just end up with another of those.
I'm very good at narrowing down choices to the bare minimum but it's making that final choice thats difficult.
