Sennheiser HD800 Certificate for Frequency Response Arrived

[subtle]

I don't have a scanner but I'll take a close up shot of my graph and post it this evening.  My chart/response looks quite different.

My hd800 graph, SN 6315
It seems that the rumor is quite true, newer hd800 has a tad deeper and a more defined bass (5db, compared to 2 - 2.5 db on the older ones), I listened one month ago a one year old hd800 and it sounded more flat and less dynamic, mine is perfectly fine, the bass is about on the same level as T1, sounds dynamic and involving, I do love both.

I still need to request for mine, but I've got the serial close to Darku's (it's in the 6000's) and I personally never thought for one second it was lacking bass either.

This graph above does not show bass response at all, as it stops at 100Hz.
 
The graph below, shows what goes on in the bass department;

It starts to roll off below 100 Hz, but still a very respectable showing.

Respectable because smoothed which Sennheiser knows as well. When I report the trebles of the HD800 are uneven with sucked out middle territory, some people concur this.

^That looks like a curve... The previous graphs do not, Why is that? Does Senn. measure in blocks instead of running through all of the frequencies?

Look carefully at the scaling of the disparate graphs.  You will find your answers.

Our frequency response measurements are taken with over 500 different sample points which provides a much more detailed representation of it's sound signature. 
 
It looks like Sennheiser is using about 22 sampling points for their graphs.  Also, the range of frequencies they sample is smaller.  We measure from 20 Hz to 20 kHz which ends up displaying a few more wiggles in the graph.

Jamey,
I for one, really appreciate having those measurements available for reference.  You provide a super valuable resource to the Head-Fi community, not to mention a great place to buy headphone gear!!
Thanks!

Thanks kwkarth!
 
We sometimes wonder how much value our measurements add but we are pretty sure that there is some value there.  As for the headphones, if manufacturers keep making great products, we'll keep selling them.

x2 Appreciation for HeadRooms graphs... just showed a friend how to use them last night. Seems like a greater amount of detail is seen on the HeadRoom graphs rather than on the Sennheiser made ones.

The HeadRoom graphs are awesome, I would be very sad if they were ever discontinued!

Long overdue, here is mine, serial no. 03388:

That's ridiculously impressive looking!

Thank you, I am quite happy with them, find them revealing of the amps and sources driving them. Listen mostly to classical music, so neutrality is very welcome.
