Unlike barbes, I haven't heard the UE11 but come from SE530's as I've stated previously. I also owned the Westone 3 for a month so can compare to those as well.
Initial Impressions:
I'll start by saying there is really no point to comparing these to universals, they're quite obviously in a different league. But universals are still my reference point since these are my first customs. I'm going to just write a few random thoughts as I listen.
The 13's go low. I'm talking all the way down. I hear bass that I didn't know existed in songs up until now. The low bass frequencies extend farther than either the W3 or SE530, which roll off in comparison. The midbass is less than the W3 though.
The highs extend all the way out, as far as I can tell. No sibilance, which was a big concern for me. Totally smooth.
The mids are perfect. Nothing was lost coming from the Shure's.
There has been no burn in that I can detect, just as I expected. They sounded immaculate from the second I hit play.
Fit is perfect. Took me no time to figure out how to insert the customs. They actually just suck themselves into place and auto seal.
I'm trying to find something to complain about to not make it sound like a biased, hype review. I guess I could say that while the fit is perfect, having customs might take a bit of getting used to - only because I'm used to soft universal tips not hard acrylic. I think that will just take a little getting used to though.
While we still don't have flying cars in 2009, at least portable audio is finally really ****ing good.
