Indeed. It'll be a dream phone who cannot afford to have Ed 9 to have a headphone that's almost identical to Ed 9. But, then again, everything look different spec wise except the drivers. So, IDK.

Second paragraph. Second sentence of ultrapaul's post.

"The PRO 900 features a new 40mm titan-plated driver and a new soft USC-Cable that is paired with Neutrik connectors"

Redesigned I suppose?

i'm pretty sure the measurements are strictly for the drivers. otherwise, the frequency response specs of the ed9 and pro750 would differ since they have difference earcups as well as different dampening, but they are listed as the exact same. moreover, the pro2500 and pro750 have the same freq response specs as well, which also contradicts your theory.

If they're strictly talking about the drivers only, then why would they show up with different impedance between Ed 9 and 750? But then, if you look at impedance for 750 and 900, they do have the same impedance. That's another irony.

My guess with difference response could just be Ultrasone not being consistent with the way they measure the specs. After all, measuring frequency response is very finicky, a small dirt on a driver could even change frequency response, though slightly. (just being hypothetical)

There may be more changes that we don't know about and that could've made the difference in frequency response but I don't think they're lying about what goes in their headphones.

i own one of the lower priced ultrasones: dj1pro and find it to be nearly the best phone for my musical tastes that i have heard. this im sure will continue the tradition: the 750 is one of my all-time favourites.

however, if the headband is the same: i cannot use it. it will just slip down my narrow head. if only ultrasone would fix this, i would buy from them again. i have to use extra padding on my dj1pro... bother me

I asked ultrasone PR if Pro 750, Ed 9 and 900 share the same titanium coated drivers and here is their response:

Quote:

Yes, the PRO 900 has the same 40mm titanium driver. The frequency range of the PRO 900 is greater: 6 - 42,000Hz. The ear cups of the PRO 900 are smaller but have a larger sound stage, similar to that of the Edition 9. Some of the other points of differentiation are the Nuetrik connectors, soft USC-cable and a carrying case.

The headband has a metal blade inside that could be bended forcing it a little bit, try the cheaper ones and see if that works for you, I needed to do the oppsite in the Editions as I have a watermelon head, grab them by the cetnral part not the extremes OK?

Interesting.

I like the spirit of smaller cups and larger soundstage. If they can have the freq response much like Edition 9, they have my vote for first good headphone released this year.

That would be my Grado SR-40 and iGrado?

I'll stick with the current style thank you...

Those are failed attempts IMO, and even worst, that is probably why they have stock with the old fashion design, as probably not much luck with the new designs neither...

If that is true, then the drivers are not the same, you can not have the same exact drivers with different freq response, unless you restrict the sound electronically, placing xovers, or filters etc....and the Edition has nothing inside that may restrict the sound electronically, so if the freq response of these are different and they claim that they use the same 40mm titanium coated drivers, there is something fishy, or wrong, there...the Editions are rated 8Hz - 35Khz, the difference is not so small, as to be an error of measuments, it is big enough specially on the high freq extension figure

But the difference between 750 and 900 is casing. The casing is supposed to be more like Ed 9, not as big as 750, therefore soundstage will be somewhat similar to Ed 9. It could be why they're called 900 instead of 8XX because of it's similarities with Ed 9.

nicely...so, PRO900 are killer for ALO HFI780, i guess ?

So you know more about this new product, one which you haven't even heard yet, than the company that actually produces it?

I can't speak for anyone else, but I think that's quite impressive.

Would it be a head to head competitor for a high-end dynamic closed can such as Denon 5000 or of the same from Audio-Technica. I think we haven't got many competitors for closed high end.
