Prompted by comments about how certain headphones have excess or rolled off treble -- at what frequency on this website does "treble" begin, according to your ears i.e. in your opinion?

I don't think this works in internet explorer by the way. You have to use firefox or chrome.

In my opinion treble starts at 4kHz, as some instruments have fundamentals up to there. Then this differentiation makes sense, bass = low fundamentals & nothing for many instruments, mids = fundamentals of every instrument, treble = harmonics.

Well, the point of the survey was to use your ears to tell us where you think treble starts, not to rely on a chart or some other instruction telling you where it starts.
 
But that's an interesting and informative chart; thank you for it.

Accidentally, my headphones start to roll off at 4kHz 

 And I gave reasons, why would this definition make sense. For me all these tones sound the same, if someone played sine wave and told me to guess which frequency range it is, I'm sure I couldn't tell.

wow at 4khz? that sounds like a very warm headphone.
 
i just found out that my cheap laptop speakers can't produce any sound below 250hz. so basically zero bass of any kind.

Roll-off for me means that it loses energy at this point but is not completely nullified. But I must admit they are quite warm sounding, here is their frequency graph compared to the neutral headphone:

it starts from 7Khz and goes up from there until 20Khz
