Well I received them this evening, and am having my initial listen. First impression (and I know how burn in can help dynamic driver phones) is that of a pretty darn narrow soundstage, and rather anemic bass. The highs and mids are nice, without any hint of harshness or sibilance, but I cannot deal with the lack of bass as I hear it now. I know burn in can help, but it's not going to make up the huge difference I'd need to feel satisfied. They don't make nearly the first impression that the Klipsch Image S4's did for me.
Changing to the narrower opening black tubes (which I read are supposed to help with bass somewhat) isn't doing much to my ears, except perhaps making the mids sound a bit more chesty and congested.
I'll keep them burning in for a while, and update with further impressions soon.
Edit- Sitting here comparing them with the IE8, I'm finding the soundstage is already sounding a little better than how I put it up above. It's not the same massive, encompassing type as the Senns, but, not bad. They have the IE8's beat on mids and treble for sure though. I just wish that bass.......
