Vocal&Newage&Folk: UM1 Pop&Rock&Electronic Guitar: SE215 (the electronic guitar sounds really good after run-in) but if you don't mind "s" sounds, GR06 is better than UM1 (based on vocals music) sorry for my poor English...

  lol i am poor man so don't worry about my wallet:P and be careful when you're on the way and noise-cancelling's on, i almost have been hit by cars for times.

Choose s754, the noise-cancelling's very useful when you're hanging out. And European or American E354's model seems no line out port(WM-PORT). But if u like newage or classic music, don't choose Walkman's stuff. I'm using S736F, just use to listen J-Pops and ACG music. Hope my opinions...
