I own the JH3A (so that's equal to the JH16FP with bass/phase adjustment) and CF Roxanne's. I can not speak for the universal Roxanne's.
By no means are the Roxanne's veiled, at least in the traditional sense of the word. What happens is MOST IEMs are very forward in presentation due to their lack of headstage. The Roxanne's presents a very wide headstage which I'm go out on a limb and say that a lot of traditional IEM folks (EDIT: traditional in the sense that their primary can is an IEM vs a full size) aren't used to. In fact, someone nailed it when they said that the headstage on the Roxanne's are larger than the LCD-X! I agree - I am LCD-3 owner and had quite a number of DAYs with the LCD-X (not just an hour at a meet).
For example, the Shure SE535s which I had the pleasure of borrowing for several months as my day to day travel companion are great example of what I'm talking about. Headstage is fairly non-existent on them and everything is shoved forward. Typically people ascribe that to "clarity" when in reality they are talking about imaging. The SE846 improves that substantially over the SE535 from what
I've read at the
cost of treble.
Another example of the veil, the Fostex TH-900, which has a noticeable
midrange dip and veiled sound. This is how Fostex though can give the impression of a wide soundstage in a close can, since the preso is set so back due that dip. I owned these cans for a few weeks before ultimately selling them because of that fact.
The Roxanne's don't even come close to sounding like any of the above headphones or IEMs. Nothing like it.
Mike at Headfonia has a r
eview up on the Roxanne's and he pretty much nails it. They are super smooth, very wide, very detailed with a slight treble roll off so they don't have that brightness the JH13/16's had.
However, they aren't so forward in headstage which is going to put off some folks, at least initially, who are used to the universal IEM "Grado" like imaging (the "thinness"). That's why I believe a lot of the "break in" comments are really folks brains adjusting to the new headstage more than anything. YMMV.
