7Hz x Crinacle Zero:2 IEM Review

[Music1969]

Can anyone tell me what the sizes of included eartips are?

Which colours are small size to largest?

Its hard for me to tell :-(

 

[Music1969]

Clearly, this is a very good IEM for the price, but I am a bit dissapointed that EQ is needed to get the best performance. I have already so many IEMs, including the original Salnotes Zero, but it seems that the Truthear Nova, while more expensive, is stealing the show:View attachment 335315

Actually , looking at 5128, Nova needs the EQ, not this Zero 2...

You are comparing two different things targeted to different curves.
The Nova screenshot by @MacClintock is a 711 measurement targeted to Harman IE 2019 v2 while your screenshot is BK measurement target to Diffuse filed curve with an arbitrary 8 db bass boost, that you can change according to preference.

If your target is Harman Curve you have to compare Zero 2 to it, and this is the outcome:

and Nova clearly doesn't need EQ while Zero 2 does.

Nah, that’s diffuse field target. The Zero 2 EQ’ed to Harman with the filters that Amir provided sounds significantly better than the stock tuning.

I gave a like and know what I have stated previously, and when taking the Harman2019IE target, it is true that the Nova is more adherent, in fact the most compliant of all IEMS I know of. Please don't come with the scoring, it takes only 40Hz to 10kHz into account and the Nova is especially good and smooth in the treble.
Having said all this, being in possession of the Variations, the Nova, the Red and the 7Hz Zero 2, for the last weeks I was almost exclusivley using the Zero 2 and have zero motivation to change this, it takes away a bit of the ear gain of the 2019 target, which is pleasant for me. Amazing IEM, not even considering the price.

 

[ehabheikal]

Does anyone know good replacement foam tips for the zero 2?

 

[MacClintock]

That is a feature and not a bug for many folks - including Crinacle, who has been vocally critical of the Harman IE target.

In fact I don't know if this is true. Looking at his and other sites, "his" supposed target is almost flat in the bass from 1kHz down, but no IEM he ever tuned has this (lack of) bass. So either he is lying about this or just not tuning any of his many IEM's to his proper target, which would be very strange to me.

 

[Music1969]

Would be a good response if you didn't show your ignorance about:
1. Coupler accuracy beyond 10kHz which is not a thing, less important for inclusion into a scoring protocol

What are rude reply

And speaking of ignorance , he did not make any comment about beyond 10kHz

We have 5128 data for that

2. The low importance of sub-40Hz for audio reproduction, and audio production.

This is even more ignorant

I procured a custom TRRS 50mm cable with a clear plastic chin slider ("8share 2.5mm 0.78mm") for $26/11 days from an Aliexpress vendor.

I specified no ear hooks, as they somewhat hamper fitment (pulling the top of the shell inward) and tend to be a tangling nuisance, with a slight loss of comfort at the bend. So with the new balanced cable, I'm gaining some theoretical headroom, but mainly the shortened length is more manageable with the Qudelix 5K application. The alternate ear tips and o-rings make the fit quite reliable for me.

Regardless of targets, I have enough (mild to moderate) sensorineural hearing loss (some age-related, some congenital) that I'm compelled to equalize all IEMs.

Focus on your perception of my tone only if you don't care about facts. Otherwise read IEC 711 specs. Read "The Mixing Engineer's Handbook" by Bobby Owsinski which states that 40Hz is the target for monitoring exipment, not sub 40Hz. Most importantly trust Sean Olive who knows this already and applies his knowledge to his model.

Why on earth would I do that when I have a real-time music spectrogram showing me high levels of sub 40Hz content for my music ?

How silly

Maybe you, Bobby and @Sean Olive only listen to Tracy Chapman (that's a joke Dr Olive will get)

Because you are using the wrong tool just to reinforce your bias. If you were interested I'd tell you there exact tool to test your ability to hear content below 40 Hz in real music.

 

[Music1969]

I can apply a high pass filter while music is playing - on and off

You don't seem to be aware that modern popular music has high content sub 40Hz

I don't think Bobby mixed any deadmau5 lol

2. The low importance of sub-40Hz for audio reproduction, and audio production.

I don't know about everyone else, but I will side with Sean Olive on setting the limits that way into his model.

The ignorant, like always, is you. Independently of how easily or accurately or whatever the response can be measured above 10kHz, it is still there and there is music material (especially overtones) and it matters. And many IEMs, for example the Truthear Zero:Red, show wide swings in this region, while the Nova (especially with foam tips) is smooth. I checked this as well with tone generator. So the fact, that this region is not included in the scoring system just shows how inaccurate it is. And if you would be knowledgable, you were aware of the fact that Sean Olive himself is not a fan of taking it too literal, it is just there for a ballpark number. Furthermore, there is also valid content in the sub 40Hz region, at least in some music I listen to. And I want to hear it properly.

So funny, and so true. There is even classical music with sub 40Hz content (not even talking about organs which can go well below 20Hz). This guy is just so limited...

I think what this guy has in mind goes along the line 'we can't measure it properly, so let's ignore it and also state that it doesn't matter, because reasons', relating to sub 40Hz and above 10 kHz. What a pathetic stance.

I'm interested. Any way to ABX this?

One tool is a high pass filter.

Get someone to turn it on and off for you, with you blind.

If you listen to acoustic jazz you might struggle.

If you listen to deadmau5, you will score 10/10 with the right part of the right tracks

We've been through all this already, it's not my problem if you refuse to learn. https://www.audiosciencereview.com/...countering-misinformation-about-autoeq.52191/

Yes, thank you. I knew that you can set something like that up.

I was wondering whether there was some kind of test, like these ones: https://abx.digitalfeed.net/
