can one assume that the lighting dongle performs the same as the usb c one?The $9 Apple A2049 will drive it to 113dB SPL before clipping. Should be enough.

Sir, we only enabled sound decision making for the task that you carried out upon ordering these.You guys are like the Home Shopping Network... crushing what little, if any, will power that I have. I caved and ordered one... 2 day free delivery, with points and rewards, $35. Now I'm buying stuff that a year ago, I had no idea existed... lol. Do you guys know the meaning of the word "Enablers"????

Do you mean a single-DD? It's really hard (but not impossible) to get that separated 200Hz bass shelf on a single driver, hence why we've opted for a dual-DD solution at least for a more budget option.@crinacle so when do we get a Harman compliant Kato killer?
Regular royalties, same with my other collaborations. I've been pretty open about this over the years.You raise a good question regarding crinnacle independence of possible conflicts of interest.
I only followed him loosely and I recall that he makes a point of not being sponsored by any headphone manufacturer etc.
Is this still the case?
How does it apply here where his name is used in the product?
Did he only receive a one time consulting fee or will he receive regular royalties based on sales?
Truthear claims that they do, unfortunately due to COVID restrictions I cannot be physically present at the factory to confirm.This is nuts performance (good thing).
Question is - is it representative of random sample
This one was sent in by Crinacle or company
Is every IEM measured for frequency response compliance during QA/QC @crinacle ?
They perform differently, to my recollection the lightning one may be marginally better. There are also regional differences (dongles sold in USA vs EU and other places have different specs, you have to identify the model number). Any model will be adequate for this and most IEMs though, so if that's your only concern you can happily just order any model from Apple and not fuss. Not worth the time to try and get a specific one unless you absolutely have a reason to require a specific one. Personally, I'd buy the USB-C for ubiquity over lighting if either would do.can one assume that the lighting dongle performs the same as the usb c one?
Thanks. Highly appreciate your transparency and clarification.Do you mean a single-DD? It's really hard (but not impossible) to get that separated 200Hz bass shelf on a single driver, hence why we've opted for a dual-DD solution at least for a more budget option.

However they had sent over quite a few random (according to them, at least) samples for me to check and confirm. The results are all here, so take it how you will.
thanks, looks like the lightning one is measured very well as well (albeit not here). ordered one. I have both iphone and android so I will just buy bothThey perform differently, to my recollection the lightning one may be marginally better.

Sure... I'll buy that... lol. BTW... is "theLaughingman" a reference to the Salinger character/story? (My dog is named "Phoebe" after Holden's little sister.)Sir, we only enabled sound decision making for the task that you carried out upon ordering these.
Fine, but a plot (distribution, histogram or density) of the score (some score) would be more reliable and straightforward. Comparing plots in this way it's kind of pointless. Who can tell if the 5th is similar to the 1st? I'm not questioning the final product, just the method to verify how much similar the samples are. I mean, this is about ensuring with a good degree of certainty that all samples belong to the same population, speaking in statistical terms. To achieve this, one needs to apply some statistics over the data, not just look at the plots.Has this been linked yet, there doesn't seem to be much deviation between samples, Crinacle measured 10 units, and the last one pictured is the one that varies the most and that was the preproduction sample, so really not much variance at all:

Yeah pretty sure they're the same.can one assume that the lighting dongle performs the same as the usb c one?
Yes, it's not straightforward to compare them, but I eyeballed key frequency areas and they were basically the same between them, I also went onto Crinacle's grapher tool and compared each sample to Sample#2 and the variation for each sample was tiny, virtually overlapped:Fine, but a plot (distribution, histogram or density) of the score (some score) would be more reliable and straightforward.

You can also use my Graph Comparison Tool to individually compare any sample to each other, if required.
Yes, that's visually better and convincing for the purposes here, I understand.Yes, it's not straightforward to compare them, but I eyeballed key frequency areas and they were basically the same between them, I also went onto Crinacle's grapher tool and compared each sample to Sample#2 and the variation for each sample was tiny, virtually overlapped:

The Variations specifically is slightly more refined than the Zero in sub-bass extension, the 3khz-7khz region, and in high frequency extension. Is it worth 10x the price? Probably not. Is it better? Yes.So why would one get the expensive Moondrop Variations etc (also very Harman) over this? I am genuinely asking, with all the cheap iems coming out now that have coherent graphs and low distortion. Why spend 500 - 700 on Thieaudio, Yanyin and all the rest of them. Will the Moondrop S8 sound better?
This is a WAF debate I absolutely do NOT need in my life.
I like to use a benchmark of -3dB at 34hz, in this case its only down -2.5 dB so, I would say that is a superficial difference for 99% of music. For ear gain region, well that is subjective as a whole but there is a compelling argument for a recession at 3-7khz actually being closer to an average objective "truth" depending on what methodology used to determine "objective" and how smoothed the approach is, especially in the occluded ear. For the HF extension, I can agree: most independent hearing aid research and even Sean Olive acknowledges the shortcomings of high frequency in his research and I believe his future research will address it with the B&K fixture. It doesn't help that is it so physiology/age dependent, and that hearing loss is not a linear phenomenon across individuals. Not to mention it is quite difficult to accurately test hearing over 10k and there are no real standards/hearing tests for these frequencies. The best we can really do at this stage is estimate.The Variations specifically is slightly more refined than the Zero in sub-bass extension, the 3khz-7khz region, and in high frequency extension.
