So bass levels (100Hz) of the HD600 are 20dB above the 1kHz level and the 10kHz levels are 15dB below the 1khz levels.

an HD600 that measures flat (within a few dB) on other measurement equipment is skewed downwards 35dB in these plots.
Not even Monsterbeats are that bad !

If I had to make a wild guess you are using pink noise and measure without compensation networks for it.
Try white noise...

Care to elaborate on what you've got going on here?   :-Z

They don't seem gain matched for the sake of easy reading.  I think there might be some high-end attenuation going on in your rig.  Can you post a wildly deviant FR from another phone?  Would be nice if you had a point to elaborate on too.

This is a obviously a joke or someone trolling. Note amplitude scales. None of these headphones roll off that much in the treble. LOCKING THREAD.
