Here ya go. These SR80 raw driver measurements were done on 9/13/11 and 12/4/11 in an garage with no temperature/humidity control. It looks like there is a slight shift of the peaks. I'll let Arnaud explain this one. Probably has to do with the speed of sound at varying temperatures.

Yep.  We can't go forgetting the importance of the medium that a wave propagates through now can we.  Don't forget the barometer...

Just for comparison and partially to corroborate Tyll's HD800 measurements. Four HD800 channels from two pairs (both s/n > 10k).

Four LCD3 channels from two pairs.

Dr. Dre Beats Studio. Two channels from one pair.

Old news. Four LCD2r1 channels from two pairs. (forgot to gate the IR - so wiggles in the bass)

I really didn't want to present this, but someone's been asking me a lot of questions. Take everything with a grain of salt. It's all shades of grey.

We need another pair of Beats.  tongue.gif

This.

 

If Monster can best Audeze in consistency does Hell freeze over?  Is it a sign of the apocalypse?  Does the Matrix divide by zero and end reality as we know it?

 

For Science!

:(  Beats #1!

Wow, those variances for the Audeze headphones really put things in perspective.

 

It makes Grado's accomplishment of maintaining the same FR across multiple headphones in eleven different product lines even more impressive!

 

 

<_<

If the problem really resides in the tensioning of the membrane (so specific to ortho-dynamic and electrostatic drivers), I'd be curious to see how other orthos fare in terms of consistency (Hifiman, Fostex, ...).

Pretty difficult to guess for me actually. The shift at 4kHz seems rather large is we consider this an acoustic resonance. If I didn't mess up, you should get not more than 0.2Hz shift for a 4kHz acoustic resonance when the temperature increase from 15 deg. Celsius to 25 (you're in socal, so that's a reasonable temperature drop from september to december no?). For humidity, I don't really know. Now, if this resonance comes from the driver / membrane, then all bets are off.

 

The bottom line though: you do a pretty darn good job at measuring your headphones with consistency!

I'm trying to imagine how Beats Studios would sound out of the Balancing Act.... basshead.gif

Worse. The Beats Studio have a built-in amp/noise cancellation circuitry that must on be for the headphone to even work.

Yet you'll still have people bitch and whine that the HD800 are made with a high quality plastic, that isn't susceptible to climate change. smily_headphones1.gif

Yep.  People seem to have an irrational fear of plastic left over from the ancient past (from my perspective anyway...) when all plastics were awful.  There are plenty of high performance polymers these days.  I think part of the problem is that its fairly difficult to identify plastics as compared to common metals or woods so everyone assumes the worst.  It would be better if makers of high end products more prominatly identified the plastics in their products and touted their benefits instead of trying to sweep it under the rug and hope in vain that no one notices.

What the Snozzcumbers?! Has anyone done such a comparison with the T1's? Please tell me they don't have as much variance as the Audeze cans?

Looks actually more so as the square wave responses vary quite a bit too.
