I’m glad you’re here Maynard. You might be the only person on this forum who cares lol.
I didn’t realize the Oratory1990 measurements are supposed to be more accurate. I opted to go with innerfidelity after looking the at HD600 graphs specifically. Those spikes after 10k don’t seem right at all to me.
I will do the test again a little later.
Oratory is using the latest, greatest, most expensive, and most standards-compliant equipment. InnerFi and Rtings are using much older gear with a straight pipe for an ear canal. In theory their measurements are meaningless above 10 kHz and problematic above 2 or 3 kHz. But OTOH I’ve seen Oratory graphs that make me scratch my head, so would really like to see each one validated by tests like you’re doing.
Here is the raw graph for the HD 600:
The red and blue lines are compensated and averaged. What’s important are the raw data for each of 5 trials. Notice how wildly the 10 to 20 kHz region differs from trial to trial. Peaks as pronounced as Oratory shows may be buried in there for all I can tell. (And Axel Grel at Sennheiser was using equipment that was no more accurate than this when developing the 600.)
But again, what do your ears hear? Mine don’t hear anything above 10 kHz, so if the Oratory graph doesn’t match what you hear with younger ears, a continuous test tone plus a flat amp & dac that settles the matter for me.
The red and blue lines are the two channels right? That’s a pretty big channel imbalance from 5-10k. I wish he used a better pair lol.
And yeah it’s hard to make sense of the trials with them bunched together. I wish he made his raw data available somewhere. From now on, I will focus on oratory’s measurements. Another good test case will be comparing the 58X, 6XX, and 600.
Okay it turns I did use the oratory1990 data for the Elex vs Clear test. The innerfidelity database doesn’t have Elex measurements. Knowing that I was already using the best data available, it’s a bit disappointing I didn’t get a closer match. But I guess one possible reason could just be manufacture variability. I have seen it suggested the Elex has it worse than normal.
Of course and to state the obvious, until you know you have an accurate graph for at least one headphone you own, there’s no way to pin down which headphone’s measurements in a simulation test is at fault. In my case, Oratory’s graph for the DT 1990 just nails it for my own DT 1990. So when I simulate another headphone on the 1990 I know any discrepancy has to come from the other headphone’s measurements.
Perhaps try this? EQ one of your headphones to the no-bass Harman curve using the Oratory graph. Now listen to it using On-line Tone Generator or whatever sine sweep approach you’re comfortable with. As you go up in FR do you hear flat or a very steady rise or fall throughout? If so, that suggests a good match. If not, try another guy’s graph. If still no joy, do the same thing with each of your headphones that have usable measurements in turn.
(Of course, if you hear the same upper mids or treble spike in multiple cases that suggests it’s one of your ear canal resonances at work, not the measurements.)
Parametric for the Sivga P-II / Blon B20 (do not know if it applies to the Sendy Aiva):
It looks like those presets are from Crinacle database on the AutoEQ github. There’s also one for the Sendy Aiva. I tried out the Aiva one and I wasn’t a fan. How are you liking that EQ on the B20?
Can you elaborate on this? I currently have the 4xx and really enjoy it and most say the Sundara is an upgrade.
Also, do you have an EQ for the 4xx?
marcgii: I tweaked them somewhat based on the graphs Sivga published. I have the P-II, not the B20, but like the settings. Tried changing the pads to the perforated Aivas, and prefer the Sivga stock ones.
[EDIT: I see the github B20 EQ post was changed 12 days ago and now the numbers are different. Guess I will see what those do…
Yes the Sundara is an upgrade. If you look at the measurement graph up top, you’ll see that the 4XX has got bit more low end and more treble around 6-10k. Those two things make the 4XX more enjoyable for me on pop music (the only thing I use the 4XX for). I also find the 4XX to have greater presence for female vocals—which is half due to the treble. The Sundara is more neutral which I guessing most people prefer.
As for EQ, I haven’t used any with the 4XX. Was there something about the 4XX you want to improve?
Ah, gotcha.
I’ve been playing around w/ EQ on the 4xx and have something that I really enjoy.
EQ settings are a mix of metal and oluv’s…

I do want to try the Sundara’s next.
That’s a pretty significant amount of EQ. I’m guessing it’s to bring it closer to the Harman curve. If you’re willing to use EQ, then the Sundara is an even safer bet
yooooo marcgii, since u seem to be an EQ whiz. what frequencies would u mess with to get a warm headphone? any good guides u know of?
I’m definitely no wiz yet lol. My strategy for getting the sound I want (aside from trial and error) is to compare the measurements between two headphones like I did with the very first post. When I think “warm” I think HD6XX, so I’d use that as my reference point. Otherwise I’d say warm sounding headphones will have greater bass emphasis centered around 100-200 hz. So you could start boosting there. But it might make more sense to lower the mids or highs instead depending on the headphone.
Also here’s a post with general resources related to EQ. Look at the video playlist and the DIY AUDIO link.
New Aiva EQ!!! With the help of the EARS, I EQ’d it to have a similar midrange to the HD600. So far the results are pretty good. But I will keep working on it and update this post later.

I based my eq off Oratory 1990’s preset :
Band 1 LOW_SHELF FC 90 Hz GAIN 4,0 dB Q 0,7
Band 2 PEAK FC 220 Hz GAIN -3,4 dB Q 0,7
Band 3 PEAK FC 1500 Hz GAIN -1,0 dB Q 3,0
Band 4 PEAK FC 2700 Hz GAIN -1,1 dB Q 6,0

Band 8 PEAK FC 7350 Hz GAIN -5,8 dB Q 5,0
Band 9 PEAK FC 8350 Hz GAIN -7,3 dB Q 3,5
Band 10 PEAK FC 15000 Hz GAIN -6,0 dB Q 1,0
And this is my current “mid forward” preset:
Band 1 LOW_SHELF FC 90 Hz GAIN 3,0 dB Q 0,7
Band 2 PEAK FC 220 Hz GAIN 0 dB Q 0,7
Band 3 PEAK FC 1500 Hz GAIN 0 dB Q 3,0
Band 4 PEAK FC 2700 Hz GAIN 0 dB Q 6,0
Band 5 PEAK FC 3700 Hz GAIN 2,6 dB Q 4,0
Band 6 PEAK FC 5500 Hz GAIN -2 dB Q 4,0
Band 7 PEAK FC 6400 Hz GAIN 0,9 dB Q 7,0
Band 8 PEAK FC 7350 Hz GAIN -5,8 dB Q 5,0
Band 9 PEAK FC 8350 Hz GAIN -7,3 dB Q 3,5
Band 10 PEAK FC 15000 Hz GAIN -6,0 dB Q 1,0
Basically my changes were lowering the bass by 1 dB to hear vocals easier, undoing oratory’s changes to most mids frequencies as he reduced most of them (He did boosted 3700 so I left that one unchanged) and I reduced the 5500 and 6400 frequencies hoping to reduce siblance a little. As you can see most of my changes are based on nothing really so any thoughts about them would be appreciated.
Here is my equalizer preset:
I’m running He400i 2020 with Ifi Zen DAC on bass boost, unbalanced, low gain, USB original cable with type c otg connector to my Pocophone F1.
The equalizer app is Wavelet.
It’s solely for EDM only, for others, I lower the 75Hz to 0.5 or 0.4. Also warning, it’s quite bassy. If you do try, don’t turn off bass boost or it will sound like crap.
Hey Y’all! Glad I found this. I have been playing around with Peace because of my messed up hearing. I don’t mind saying it, I need a little help. I have found a set that I find very pleasing when streaming AMHD.
As you can see, there isn’t a lot in it. Just enough to have fun and help me past my bad spots. This a great tool.
