Ultrasone Pro900 (defective) Frequency Response and CSD Waterfall Plot.
I'm pretty sure this headphone is defective. At least I would hope so.



This is probably one of Ultrasone's better sounding headphones.

I thought everyone should get a laugh. I do know this pair has been used and abused a lot in the past few years and probably ground into the dirt.

Looks about right for the 900. Ultrasone doesn't bother with petty goals like reproducing a reference curve.

I still have my pair lying around somewhere underneath the couch. They don't sound as quite in your face offensive as the graph suggests, but after a half hour of listening you inevitably develop a headache.

Ultrasone may be onto something. If you average the two channels, the curve looks pretty decent.

I believe that's how their U-sound technology works. Leverages the ear/brain adaptive mechanisms.

Seriously though, these are one of the better Ultrasones.

Are these the Dark Knight special edition? These look like they were probably tuned specifically to account for the outer-ear physiology of Harvey Dent:

Oh sweet lord thanks for the laugh, made my day. 

You sure do seem to get a lot of defective headphones Marv.  You have really bad luck.  Everyone else on HF seems to get perfectly matched "good versions" which is verified by the the 99% of HF who have superhuman channel imabalance detection devices implanted in their brains.

Harvey Dent? I love you guys.  ;D :-*

But, wow Pro900. Didn't anything could be that poorly matched.
