In practical terms, i.e. when buying some phones for actual money; can we safely conclude that frequency graphs like the ones on Headroom are adequate indicators of sound quality?

A "neutral" frequency response, is the first thing that people ask when looking for a headphone.
But it's not enough to warrant good sound quality.
In other hand, you'd see people rejecting some headphones models , just by looking at the frequency responses.
It's the case of the expensive denon d7100, there's an important bass emphasis, if you look at he graph.

All the more, there's no general consensus that "neutral" means "flat". Think for example to different design choices like free field vs diffuse field equalization.

These considerations are a bit too technical for me. I guess that when you use the word "flat", you means that it sounds "flat" to the listeners,
and not a "flat" frequency response. I already before tried to "flatten" the freq response of a headphone, and the result is not great.
I 've never heard of free field equalization before, I think all modern headphones use diffuse field equalization.

I guess that when you use the word "flat", you means that it sounds "flat" to the listeners, and not a "flat" frequency response.

I meant exactly "flat frequency response", which is a precise concept and quite easy to quantitatively assess, whereas "neutral" is a qualitative concept and subject to opinions and interpretations that often differ from listener to listener. You were speaking of frequency response and used the word "neutrality" and what I wanted to say, in other words, was that a flat frequency response measurement, which for example is considered at least a good starting point to achieve subjective neutrality for speakers, is most often considered a wrong one for headphones (edit: should you ever encounter one... wink.gif).

But from other posts you seem to know already.
