Dear community, has anyone experiences concerning digital equalizers to change the sonic balance of headphones or "correct" frequency responses ? My idea is to tune the sonic balance of a HD 650 to more linear frequency response (no or less roll-off to higher frequencies as it is now). How...

Why can the HD6xx Models not be used as studio monitors ? What about the use of a digital equalizer ? In my opinion this should be a sufficient way to tune the sonic balance of the HD6xx (and of course any other headphone) without remarkable side effects. I am indeed strongly thinking about...

It is nice to see this discussion as I am in the same situation with my new HD650. Till now I have connected my old Beyer DT770 to the speaker outputs of my Onkyo Receiver. I used a voltage divider optimised to high damping factor and a voltage ratio of 10:1. This means 10Ohm in serious to the...
