Please point to me where there has been a purely flat measured headphone that can correlate to nonsense such as a: flat measured headphone will have emphasis on this part of the sound that will sound warm or brighter or darker? You're also forgetting the amplification which can greatly affect how headphones measure. No two things measure identical.
I don't know about you but Headroom surely doesn't speak for me. Ever wondered what the FR graphs of the Orpheus or Luis' Paradox looked like? Can you then tell me achieving a flat response is strictly for speakers?
You might want to choosing your facts wisely when presenting it as a form of basis for an argument.
Thanks you just the post I was looking for.
I'm not treating them as the "end be all," I chose them as one example since I see their graphs posted on Head-Fi more than any other site's graphs. It is sound logic no? Here's another example from Dan (Mr. Speakers)

As usual, the rolloff that starts at about 1.5K is characteristic of our headphone measurement system, and actually this represents linear. What's going on in the plot above 5K is very random based on micro adjustments of the phone on the test fixture.
I always hesitate to put plots out as many people expect headphone measurements to look like ruler flat speaker plots, but the reality is above 1.5K peaks and troughs are part of "flat" measurements.
I understand that people measure graphs differently, but I don't believe that it is all arbitrary. I think there must be some science behind running white noise through headphones and recording the result with a microphone. If any headphone makers want to chime in and let us know if a flat line from 20Hz to 20kHz is their goal, that would be helpful.
It makes sense to me that with headphone drivers being next to our ears, a rolloff would be more ideal from 1kHz to 20kHz than completely flat. I'm only speaking from my experience working with sound, I am not claiming to be an expert in any way. I am more than happy to be completely wrong on this and many other topics. It's much more important to me to learn and increase my knowledge than to be right.
This will be my last post on this topic as I don't feel this conversation is constructive. I love discussion and debate and even disagreement as this often helps to bring out truth. What isn't helpful to me is when debate turns into argument, with accompanying statements like "nonsense" "facepalm" etc. Then we go from constructive discussion to a battle of egos. And it's not just in this case, I've seen more of this type of unhelpful argument going on in other threads recently. This is disappointing to me since I joined Head-Fi because there seemed to be a lot less of that here than on other forums. I strongly believe that there can be lively discussion and disagreement without a loss of civility and basic respect for each other.
