Hi In the recent review of the Sennheiser HD560s I noticed that a new "percieved" frequency response compensation was added. This addition was claimed to be the result of the pinna interaction which is something that has been touched before in other reviews (for example in the AKG K712 review it was explained that the dip at 3.5kHz wasn't "really" there which corresponds well with rtings findings of the k712 pro:s "passive soundstage"). I am very familiar with the test setup used here and how it doesn't in it's current version have a pinna model (I studied the documents when I built my own testing rig  ). In the HD560s review however was this compensation not really explained more than: Angled driver=This compensation. The quote; "I found that area to be about 6dB above neutral" might give some insight but how was this 6dB "found"?

The quote; "I found that area to be about 6dB above neutral" might give some insight but how was this 6dB "found"? In case of the K712 there are already measurements showing what the effect was. Not so in the case of the HD560S. When I were to use a Pinna there would be errors in the frequency range above 7kHz so opted not to add a Pinna. Instead I compare to a reference headphone while using a DEQ2496 to determine what it sounds like and then draw it in. When the HD560S sounds like my reference I look at the plots + found EQ which gives me the an idea of the perceived response. I might just publish measurements with the reverse EQ so I can create a perceived sound.
