Just received my UE6000 and listened for like 3 hours in active mod. compared to my old Momentum:
1, Comfort-wise, UE6K is a surprise in this aspect. It's hard to tell which one is more comfortable (I thought Momentum would be a clear winner here, but no...) UE6K is way more heavy than Momentum, but the era pad is significantly bigger and given more space for my ear. The leather pad in Momentum is still a killer, but due to the smaller pad, it would sometimes push my glasses and hurt a little bit. However, for a very long time wearing (2 hours+), I think Momentum would take advantage for its light weight...
2, Looks. Oh man, these two are both very sexy headphones. I like Momentum to go with my suit when I get to work, I prefer UE6000 with my t-shirt when I fooling around with my friends. The point is, by far every body knew Momentum is a good-looking headphone, for me, UE6000 is also wonderfully checking all the boxes in this regard.
3, Sound. well, first, UE6000 is not totally burned-in; second, I DO NOT use any amp. My purpose is to find a perfect on-the -go headphone for my unamped IPC. That means i have to put UE6K on active mode (otherwise it's just too flat and dark with a IPC) So the comparison is may not fair for UE6000....Anyway, by far, Momentum is the clear winner for my taste (Chinese folk an indie rock and jazz). Bass alone, UE6000 is more deep and punchy. That will actually help in some metal rack tracks (not a big fan), And the treble is also significantly emphasized on the active mode...that turned out to be a mess in some of my tracks I can not hear the vocal clearly...and the soundstage is kinda of compressed or at least blurred compared to Momentum. For Momentum, bass is much more controlled and less powerful. it's not that fun to hear in some tracks but it's more clear and would never push the mid-range. It's just right there in my ear, i like that. I also found the soundstage and the instrument separation is more accurate on Momentum. thus the general SQ for Momentum is more nature and enjoyable for me.
Again, UE6000 is not totally burned-in. and I have only listened for less than 5 hours....I'll wear this shinny baby for about another 3-4 days and then I'll come back to make a final judgment.
