Thank for comments! Yup, W series sound more fun, musical to me, same as my W4r ! UM series is more "stage" monitor, it have less LO freq in it. W series is more "Audiophile" genre in mind!
I still have the UM3x, that have change couple weeks later for the W4r. Never use, yet, my IEM amped! Am an hurry to see all the transformation! ....
Well I went for it, $200 Canadian. Yea the W30 sounds (tuned) like my speaker system so that's great when I'm on the go and want a home stereo sound. The UMPro30 is still a very good sounding set, the bass is much tighter, cleaner and digs deeper, whereas the W30 can't handle the sub bass as nicely. Both are terrific earphones for different reasons. Rock on!
