Before I get ripped to shreds, yes, I did indeed use the search bar to look for previous Westone 3 vs Um3x threads. The reason I'm asking is because A) I have different preferences compared to previous threads B) Newer opinions always help, too.
I was originally planning to buy something in ~200-250 range(previous thread), but was able to upgrade my budget, and have been eying both of these IEMs for awhile. From what I've thread of the previous threads here, it seems that UM3x is the "truer" of the two in detailing/showing the song and how it was supposed to sound(along with flaws, of course), but has "neutral/dull" sound. While the W3 has a more "fun" sound but isn't as true as the UM3x.
Now, I listen to mostly Metalcore, Alternative, Indie-Rock, Hip-Hop, so maybe that will help for you guys to steer me in the right direction. I love a good soundstage, and I also prefer for the headphones to have a balanced feel. I'm not a fan of hearing certain aspects overpower the others(e.g base), so nice balance is a plus. I also want the headphones to have good isolation because my commute usually consists trains/buses/walking, so something that will block(hopefully) most of them off would be great. Finally, I want the headphones to sound enjoyable and fun(heh, W3 description), so that I don't get bored of my music.
