It may be why I pref it the most as I listen to classical music frequently. Its never harsh and transparency is key for me and it does that ver very well. But for jazz and classical I appreciate a very extended treble.

So I guess that 16.5khz - 19khz +~3dB is that elevated treble we all hear. Interesting to note that it's not actually louder than the bass, and is only slightly louder than the mids. It's mostly louder compared to the rest of the treble.

It is a bit disappointing to see the FR fluctuate a few times by about 5dB in the trebles, but it's kind of impressive how flat it manages to hold itself for large stretches of it. That probably lends to how smooth these sound and how they can feel trebley but not peaky

 

I need to learn a bit more about reading the rest of the graphs to form opinions. Particularly the square wave response. I can tell an atrocious graph from a great one, but in terms of nitpicking how do these compare to other top-end contenders in their impact?

 

Finally, the ruler flat impedance vs. frequency graph to be believed?

I refer you to this post for the answer. http://www.head-fi.org/forum/thread/542142/need-help-understanding-planar-cans-like-lcd-2-and-he-5#post_7323505

Indeed, planar magnetic driver headphones have a flat impedance curve.

 

And looking at the HE-6's FR graph by itself, it is notable that while there are peaks and dips, the FR from 20Hz to 10KHz is +4/-5dB - that is a relatively tight window (a good thing).

Thanks, I just checked the impedance vs frequency of the other orthodynamic hifiman headphones and see that they indeed are similar. Interesting, I wish I better understood why they were so stable.

post #3141 of 14032

Perhaps I am mistaken on this, but if one looks a the FR response graphs of all measured headphones, the high frequency response curves are quite similar, with several peaks and valleys.  Of course the lesser quality phones typically have more roll-of of the high frequencies, but it is my understanding that these high-frequency peaks and valleys are due to the response curve of the human ear whose sensitivity varies with frequency.   Most of the published headphone measurements are done using a binaural dummy head whose response curves are designed to be similar to that of the average human ear.   Trying to measure headphone performance by any other means would result in meaningless information.

Headroom for sure uses the dummy head in their measurements.  They do make clear on their site that some peaks and valleys in the treble between 2-8 kHz are to be EXPECTED.  So yes, one has to be very careful not to read too much into these high-prequency peaks and valleys.  This is why, when I look at the HE-6's FR graph, what I see is a pretty flat overall response, with no roll off at EITHER frequency extreme.  Looks pretty good to me.

What I was thinking.  Just like when custom IEMs are built.  They are tuned as close as possible to projected curve that correlates to human hearing.  Not tuned to be ruler flat.

The grain of salt should become rule of thumb because on this forum its not what you see but what you hear and no two pairs are alike.

Another look has the HE6 flatter overall graph vs the T1 and HD800. It would appear that the HE6 was slightly brighter. I didn't hear that though and to suggest, as the graph might look, that there's more bloat to the mids in the HD800 and T1 is not the case to me either. If you take the inverse you could say the HE6 could have leaner mids. Also not what I heard. The "peak" of the HE6 highs occurs at about 500hz after the HD800 and extends from 7kHz to 9kHz. Suggesting again a brighter 'phone. What the graph doesn't show is the distortion at those levels. The distortion might make the HE6 highs seem more refined. All speculation on my part.

What I heard was a nicely balanced headphone in the HE6. But I also think the HD800 sounds great. As does the T1. Neither sound exactly the same but not as far apart as the LCD2 does vs the other three.

Plus, many of the things I hear from the HE-6 that I think are better than the HD800 and T1 are not FR related.

Which is why I always say those graphs should be really taken with many grains of salt. My post was to show just how differently the HE-6s were "measured" compared with Head-fiers whose ears I trust (yourself, Skylab, Frank, rhythmdevils, etc...) described what they were hearing. smile.gif

 

post #3147 of 14032

But actually I don't think the FR graph is much different at all versus what I hear. 

post #3148 of 14032

Interesting...the bass on the T1's does show on the graph to be more impactful (including deep bass) and they do appear brighter than the T1s (and almost similar to the HD800s in that regard...except for their peak being about 500Hz ish later than the Sennheisers).

Actually, the T1 will seem to have a lower level of deep bass than the HE-6 because the upper bass is elevated higher than the deep bass with the T1, versus the HE-6, where the deep bass is higher in level than the upper bass.  I also find the HE-6 to be slightly hotter in the treble overall than the T1, and have always thought and said so.

Thanks Rob for you confirmation. I really would love to hear these cans. smile.gif
