I can't comment on that question becuase this is not my thread that I can feel free to do so. I can answer your question if it was posted in the P-51 manufacturer's sponsored thread.
As to the music I listened to using the Westone 3, I would say Jazz, Female vocals, acoustical instruments & simphony. I do not listen to rock, country & rap, Sorry.
I added a link to your comments in my big Westone 3 review thread, at the bottom of my first post along with other people's feedback and impressions. http://www.head-fi.org/forums/f103/r...thread-386477/
