  By the way, here's what my more refined subjective perception of the HE560 FR is, superimposed over an actual FR measurement by ultrabike of Jergpad modded HE500s
 
 

 
Anyone who is even remotely familiar with reading frequency response plots should be able to imagine the sound signature. Really the main points of interest are the <50 Hz region, the 2kHz region, 4-6kHz region, 10kHz, and ~12kHz region.
 
Keep in mind ofc this is still purely subjective and by-ear (with some tone-sweep testing and comparisons), it's how it sounds to my ears, and the ups and downs are qualitative rather than quantitative.

Is that post-mod HE-560?

HiFiMAN needs to chime in on the status.

Might be some cancellations if they don't make their late April promise!

Count me in on that!

What mod?

 

[Ultrainferno]

Would you cancel just for that? You really didn't take that into account?

I think 30 days from time of pre-order is a fair wait. When was pre-order?

Officially announced 15 days ago, but the preorder page was up since April 10 I think, so 19 days.

I think what tigon_ridge and the others meant was the baffle mod that you told that you did to yours, and presented the idea to Dr. Fang.
Were the subjective perceived frequency response graphs on the HE560 that you posted, before or after you did the baffle mod?
Thanks.

That would mean the middle of May?  Instead of the end of April they have been saying, someone posted that their customer service told him before May 1, and tomorrow is it for that!

Well this is a test unit with the baffle mod officially implemented, so it's a baffle-"fixed" version, no longer a mod. All production units will have this fix too.
 
The rise below 50 Hz with the HE500 plot is due to the jergpad mod, regular HE500 sub-bass is linear with a roll-off at the end. HE560's subbass is a lot tighter and lower in harmonic distortion, and as such even if it is linear (it very much could be), the perceived volume is less. Don't dwell too much on my MSpaint FR.

So do these lines from the review still apply?
 
"(updated Apr. 10, 2014) HE560's bass is as extended as HE500, as punchy/impactful as HE400, and is tighter and more articulate than both the predecessors."
"(updated Apr. 10, 2014) Bass is extremely tight and extended, with excellent physicality and tactility to it. One of the few headphones that give me physical sensation of bass without being "one-note-y". "
 
Because all I can really read out of this is praise, praise and praise for the bass!
Doesn't seem like there is any perceived roll-off that'd impact the ability to render bass down to the deepest notes all-round?

Why wouldn't they apply? I think you guys are misinterpreting what I drew for an early roll-off, because that's not. HE560's low frequency behaviour extends as far as HE500 but with much higher control and lower distortion. Extension =/= tilt.
 
And again, the tilt is what I perceive, which is not accounting for THD, so it could very well end up measuring completely linear, but less in volume in the <50 region because there is less harmonic distortion adding to the volume.
 
Maybe I'm overestimating everyones' measurement interpretation skills

Here's a cartoon exaggerated representation of what I mean about the perceived low bass behaviour
 
 

 
So which one extends better? Or are they more or less equivalent (just different in extension quality)? You guys decide.
