I'm glad to hear about this as my room is small (until I build I am going to be happy with it!). I have the D5's, too, and so your comments about even them sounding better is very intriguing.

It really is like night and day as far as I'm concerned! My room appeared to have large spikes at around 50Hz, 150Hz and 400Hz as well as some serious dips around 1.2kHz and 6kHz. Ironing those problems out with ARC has made a hell of a difference to the sound. 

I have ARC #1....  It is sweet.  I too forgot to shut it off on exporting my first tune. 
 
As far as ARC'ing headphones.... it's called ROOM correction. And it's purpose is to try to alleviate some of the deficiencies in the room. But, you already know that.  Cans, are what they are.  I suspect that they could model the various cans and have presets to correct for them though..... seems doable.
 
I really need to get back to making ARC a habit. I've kind of drifted away from using it. SO..... I should take the time and do another setup, and start back to using it on every song. I guess the reason I stopped using it is that I am very familiar with the overall sound of the room, and the speakers, and just got lazy. Either one, two, or all three.

I accidentally left it on when I switched to the cans earlier. Lesson learned. Incidentally, I wonder if they'll ever come up with something that "corrects" headphones....

They'd need a foam model of your head with mics in the ears to measure, wouldn't they?

That's what I'm thinking. Totally doable!

Or perhaps they could sell a "can" version of ARC with microphone-equipped earplugs in place of the ARC mic. That would better take into account the physical properties of your head. 
 
My DT770 phones have the potential to be ruler flat between 5-30000 Hz with the right corrections! That would be great, and such a plugin would also have the ability to introduce crosstalk/room interaction to simulate real speakers like many apps such as Focusrite's VRM and Toneboosters' ISOne do!

Headphone compensation is a much easier task than attempting to correct room acoustics. With headphones, it's all about the deficiencies of the headphones themselves, deficiencies that are not as dynamic as room problems. Consequently, any parametric equalizer can manage it, as long as you have a reliable frequency response curve to advise you.
 
A good resource for that kind of information is headphone.com. It's what enabled me to create this correction for my day-to-day headphones (ATH-M50):
 

That's a point BF. And I have ATH-M50's as well, so if you don't mind, I think I'll just nab your EQ settings from you right there 

This is what the link gave me for the ATH-M50's. 

 

Thanks Bitflipper! That is very handy to know about.
@ sharke     I would love to get ARC  and find out about my room (and the next room, too).
It has moved up the list since this thread started.

I'm a happy ARC2 user and a happy ATH-M50 owner. I'll also be stealing Bit's eq settings!

Yeah, I hadn't really ever thought of EQing my phones! So that'll be interesting to try on my ATH M50 and 7506's

Silly question but is this applied to master bus while mixing or is this something done at the end to compensate? I work with a lot kids who do a lot of mixing on headphones and would like to share this resource. Just want to make sure I am sharing accurate info.
