Nevermind, it's working now :) Thank you. More or less they look as I expected, though mine are not as "hot" at 7-8KHz as that.

Seeing those graphs, in some ways, I now have more respect for Ultrasone. I guess their tuning is intentional.

Not Senn standards, but decent. Much better than Beyer and probably better than Grado. Although I know that doesn't say much.

The FR seems to be very similar indeed, lifted lows and 'grainy' emphasized highs.
Mids seem decent on most of their products.
I have no idea how much different the drivers of all these products are (a bit like the Grado range ?)
Maybe they just selected their best measuring headphones (with respect to driver matching) to create the FR plots they have.

They must be doing something right as Ultrasone seems to have a following cult that swear by their products.
But then again lots of followers for beats as well (granted, for a different reason  ;))

I also have plots for: HFI650, HFI700, HFI780, HFI2200 and Pro750 for those that are interested.
Hiya, former lurker here. I'd love to see the HFI700 graph; I'm a former owner and have been searching high and low for some graphical reference.

Nice upto 2kHz !
Alas everything above is a bit  :-0

Ah... might as well upload them all:

Ultrasone Pro750 (above) not even measuring that bad, no idea how it sounds.


HFI650 (above)


HFI780 (above)
mind the vertical scale, it differs from the others just like the Pro900 plot.

If I had to take a wild guess I'd say some of these headphones use the same drivers  :)p8

The HFI700 was a derivative version of the HFI650 - as can be seen, they're almost identical.

Thanks much for posting - solves that one for me!

Interesting charts. I have owned HFI650 for a short time, enough to equalize it.
The dips (different from my pair) are actually ringing, but not all that long. 12.5k peak was quite annoying without eq, giving sound a really brittle feel. :)p14

That headphone is probably the least ringing of the Ultrasone offerings, but channel matching in the high end was off, giving soundstaing a really weird feel.
Very sensitive to head placement and the optimal one caused them to slip off the head at times.

In case you're interested, I still have the old correction curve.  :-0 Not my usual standard of precision, but it should give you an idea exactly how flawed my pair was.


At least they're consistently sucking, I give them that.
