There's Something About Ultrasone…

[Dexdexter]

OK, so let's look at the graphs of some of the major USone playas.

Edition 7:



HFI 650:



PROline 750:



HFI 2200 ULE:



PROline 2500:



Now, to my eyes, the response curves here for the Edition 7 and the HFI 650 look very similar, as do the HFI 2200 ULE and PROline 2500.

But my ears have already told me that the PROline 2500 and HFI 2200 ULE are vastly different in terms of actual presentation and performance, and I would certainly expect a similar (and really, it oughta be huge) gap between the Edition 7 and the HFI 650.

So I suspect that there's much more to this story than meets the eye.

Forgot your glasses? These certainly dont look as similar as you make it out. And yes there is much more to it, like distortion, driver matching, impedance curve and so on. I still stand by my point that it can give a pretty good idea of what to expect by an experienced head-fier. OFCOURSE it wont tell you how good the instrument seperation or resolving capabilities will be for example.

Anyway ill be getting my proline 750 tomorrow

OK, glasses back on, but I'm struggling here.

Considering these two not-very-similar-at-all-whatsoever looking curves:

Ultrasone Edition 7, $3000.00



Ultrasone HFI 650, $249.00



Kindly explain to me the wide differences between the two curves and how they would lead you to know what to expect from the respective headphones' performance.

Best, Dex

P.S. Congrats on the 750s!

Thanks.

And maybe this helps

Wasnt i clear enough? They are useless to compare performance BUT it can give you a hint on its soundsignature. I hope thats clear now finally
Get a parametric software EQ and you'll quickly hear yourself what signature youll get with eq'ing out a little at 200-300hz.
Comparing the 750 to the 2500 graphs tells me CLEARLY what im looking for in open vs closed design, especially since the 2 AT graphs show me the same differences in their open vs closed designs (dive at 300hz!).

Ofcourse i dont know how it will sound still, but i'm pretty sure how it wont sound

Im getting a headache and i think my last posts were kind of useless... Well gotta kill time till my cans arrive

Yes, I understand what you're saying. But I would shift your bold emphasis to read instead:

They are useless to compare performance BUT it can give you a hint on its soundsignature.

With loudspeakers, consumers seem to demand frequency response curves to reassure them that the sound they are buying into has some sort of basis in the science of acoustics. And manufacturers are only too happy to oblige.

But in the end, it really means little, given all the other varying intangibles that factor into the final sonic result.

And I'm sure those 750s can't get to you fast enough! Should solve your headache 'tho. Just don't listen to them critically until they have a good 100 hours burn-in. You will be rewarded!

The only thing that those graphs show, is that they will give you an idea, of how the freq response is distributed along the whole spectrum, in maybe a similar way, (and IMO not very similar neither as those graphs are not linear) but soundwise they tell you very little, the Senns has a veil that the Edition 7 does not have, in what part of the graph is that veil, is that in the graph? Also don't froget that for similar that they look, for every 3 db you are almost duplication the SPL, so the differences are not that subtle between the curves if you ask me....

[bizkid]

Guys! All i wanted to say is: The graph clearly shows that the Proline 750 is going to sound like a closed can (which it is!) and not much like the open 2500 variant! However it might share the same refinement, resolution and detail. Can we agree on that? Pleaseeee

Thats what i also told dexdexter just a few posts back.

Yes we can agree, disagree or whatever you want man, just chill out....

Nobody is saying that you are wrong or right, just that those two curves are sometimes misleading in what they indeed represent, they also normalize them sometimes, and use logaritmic scales what is sometimes confusing, and in the last acception, sometimes honestly I do not trust the source as my ears tell me the opposite, but you can use them as a reference at least of what ot expect...

No! No agreeing on Head-fi, I won't allow it!
