Well, to be fair I listened to some early latin jazz last night, and they did sound very good. They have an impactful and very warm sound, so with some tracks they did not sound as delicate as I would have liked. But I'm comparing them to the HP-3, which have a level of transparency and detail that I don't think you'll find in any dynamic, unless you shoot for the absolute top. They really excel at soul, R&B, reggae, probably rock and hip hop (both of which I don't listen to), but do pretty well with most other genres. What will definitely wow a first listener is the amount and extension of bass, and forceful mids.
Remember these cost 40 euros, and I'm liking them much more than phones which cost 3x or 4x. Of course, if you spend several hundreds on a pair of dynamics you will get better sound. But then they will be bulky, you will be scared of taking them around, etc. And how many of us can afford to spend that kind of money? These should be considered a good, less expensive alternative to the ATH-ES7, AKG K141/171, SR-60/80, etc.
I think they should be a mandatory buy for headfi noobs: they would cost them little, and save them lots of grief and money spent on crappy phones. I would have been very happy had someone told me to buy them early last year, and could have saved money to build a proper setup instead of spending it on several low or mid-end phones which sound pretty awful, Sextetts and K400/K401 included. But maybe that's just my tastes.
What I also did found last night, is that their impactful sound and big, deep, clean bass make them perform incredibly well at low volumes (if you are wondering, they sound good even loud), something which few phones can do.
As for the longish cable, reterminating it should be a 2 minutes job.
Edit: the soundstage is not large, but they don't have that "in your head" feeling either.
