Enter your headphones' name at first. And don't forget to put the tick near the graph "Yes, please send me the frequency response certificate for my HD 800" on the next page!

In this way...

Kind of interesting observing these charts.  The new ones seem to be "flatter" through 6khz than the older pairs, and if they have any peak at all it's around 10khz.  

 

But like Antedote said I'm suspecting it's just normal variation here and there.  Some of you have indeed gotten "lucky."  I would be tempted to swap out for a new pair but retail is about 2x what I paid for my early SN HD800.

Some listeners have keen ears, and might conceivably be able to tell the difference between HD800s of different vintages. But I have a feeling that, given access to all sorts of HD800, most people would not be able to distinguish between "old" and "new" versions.

 

I'll go one step further: given access to the data in HD800 charts, it will be impossible to distinguish between older and newer pairs. As you suggested, it's normal variation.

 

And of you want to disprove this, there's a wealth of data in this thread.

It appears that HD800 with newer serial numbers, eg 10,000 and above, the low frequencies have about 3 db more than the older ones.  3 db means the bass is almost double.  Furthermore the 6 KHz peak also seems to be less.

Mine falls into the newer batch and I found the bass is sufficient and there is no harshness at high frequencies.  May be I am one of the lucky ones L3000.gif.

I will be receiving my chart in a few weeks.....

 

My pair are 17xxx and with around 150 hours, the highs has really smoothed significantly. The bass is good and have a very nice texture and decay, I would still prefer a tad more weight to it........

Very good observation about the lows being about 3db higher on the newer run of HD800s; that makes perfect sense, given the graphs I've studied. I can't say that I noticed the same differences relative to the 6khz peak, which is still very much there on most printouts. In any case, I'm pleased that so many HD800 users are so generous with with graphs and observations.

Um, I don't see that at all. Mine are serial number 64XX and they look almost identical to the serial numbers 12K and higher. Older ones like less than 1000 ish do look to have less bass though.

My observations are a little different than a prior poster, but I basically agree with his point. There does seem to be an elevation in the HD800 bass through the run, starting at around SN#4000. You won't find a similar bump with SN#100-3000.

 

I haven't had a chance to compare headphones of different vintages, so I can't even say that the differences are significant, or even noticeable. But it's there.

My observations are a little different than a prior poster, but I basically agree with his point. There does seem to be an consistent elevation in the HD800 bass through the run, starting at around SN #3500. HD800s from SN#100-3000 are relatively flat, with rare exceptions.

 

The good news? My #00595 is one of the exceptions:

 

700

 

I'm not sure what that means, if anything, but I've always enjoyed the sound of these phones.

My pair, S/N 15XXX.

That's all that really matters in the end.  smile.gif

 

FWIW, here's my FR graph:
