7Hz x Crinacle Zero:2 IEM Review

[Jimbob54]

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.

I think I have heard/ read Crinacle say his original 2020 target was left deliberately flat in the bass not because that was his preference for bass levels in an IEM but that it was such a matter of preference he just left the"target" flat so people could just judge where the bass in the DUT was compared to where they might like it and decide if it was enough or too much. Not sure why he then went to a gentle slope for the 2023.

I'm interested. Any way to ABX this?

You can use any ABX tool. First you need to prepare a short segment of a familiar song. Then make a copy of the segment and apply a hi-pass filter on it. For this you can use Audacity.

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

That's not how you determine audibility.

Please read :

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

Please read :

I'm not seeing the report of your ABX trials, did you forget to attach it, or does it not exist?

You can drop the name of Sean Olive as many times as you want, you will still remain a dwarf and ignorant in front of him and most people here.

Neither will you and you are the guy opposing Sean Olives judgement, so that's a weird attack. Am I having a conversation with an alt of the AHS founder again?

 

[MacClintock]

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/

Which part did you not understand? Just save one version of a bass heavy track as is and another one with a high-pass filter. Then ABX it. If there is in that specific track enough sub 40Hz information, it will be easy to pass.

Might be true, I remember heaving heard something like that as well. But while I like some of the IEMs he has tuned, I, in fact, couldn't care less about his personal target, as there is no research behind it.

I understood everything. I'm just on vacation and wanted to try it with my phone.

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/

You might want to listen to minutes 21.40 till 23:30 of this talk:

He mentions some random people on the internet interpreting the scoring system wrongly. If I am not mistaking, he had especially you in mind.

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

Nova does need EQ around 425Hz.

it is known issue of 711 that doesn't show, that gets picked up in 5128 measurements.

I wasn't saying Nova not needing eq at all, but that Nova is an iem produced targeting the Harman 2019 curve, and it nails it pretty well as it is.
I don't know about this 425 Hz issue but if you refer to Nova 5128 measurements then again they can be targeted only to Diffuse filed curve, and you cannot use then to eq toward Harman 2019.

The Harman 2019 curve is based on 711 rig

Which fails to show issue at around 400Hz that is picked up on 5128

So yes it nails Harman curve but has this small fault that should be EQ'ed

 

[Bow_Wazoo]

Has anyone compared this with the fd5 or fd7?

 

[digitalfrost]

I am using Moondrop spring tips

My ears are different sizes. While in my left ear, bascially anything fits ok, my right ear is somehow much bigger.

The XL spring tips were a very good solution that works well for me. But it's kinda strange that they have such a big difference between the L and the XL.

 

[Somafunk]

My ears are different sizes. While in my left ear, bascially anything fits ok, my right ear is somehow much bigger.

I wouldn’t worry, just about everyone’s ears are different sizes, I have to use a smaller width/sized eartip in my left ear compared to right unless the silicone is particularly soft/flexible such as spring tips. Dunu S&S have quite thick silicone rubber but get the best fit so I size down for left ear.

 

[ObjectiveSubjectivist]

Update on my situation. Just now my Truthear Zero Red arrived and no matter which tips I use, the bass is SIGNIFICANTLY more pronounced. It's like day and night. Especially when I use my own tips from my old in-ear headphones. So ultimately this begs the question: is it really anatomical reasons why the Zero:2s sound so thin for me.

Seal problems and ear canal length. Nothing new, typical iem "issues"

 

[Cote Dazur]

So ultimately this begs the question: is it really anatomical reasons why the Zero:2s sound so thin for me.

I am in the same boat as you, my Truthear Zero, physically identical to the Red, give me a good fit with great sound, excellent bass without much fuss.
The Zero 2, can also give good sound, but I need to place them at a very different angle in my ears, if I place them where they would naturally go, like I do with the Truthear Zero, I get a very mediocre sound with no bass.
Anatomy is a very important factor in relation to the different IEM, more important than most other aspect, in my experience.

 

[Booker]

I bought the original TH ZERO and loved the sound. But the ZEROs are not very comfortable for me. That's why I bought the Sundaras. Then I saw this review and bought the ZERO:2. Since then I have listened to music mainly through them. The problem is that I got bored with the sound of my main audio system with the speakers of that time. I'm just saying :/.

 

[t1m9k86]

The importance of a good seal with IEM cannot be understated. That alone is the most important thing to get right IME. If I place the Red tips of the Zero 2 into my ears it is very difficult to get a good seal even though they are the proper size for my ear. If I take a wet wash rag or paper towel and wet my ear canal (give yourself a wet willy!) the red tips will form an excellent seal especially after the rubber warms up (give it a couple minutes). Bass will be exactly here it should be. Key is to a wash and wet the ear canal before insertion FTW.

IME foam tips will always give me a good seal, but I prefer the audio much more with silicone tips.

My Zero 2 continues to impress and is my goto IEM. Simply stunning bang for buck.

@GPJ so despite your initial comment regarding no EQ and using the OG Zero's, did you EQ the 2's to get them to be your goto IEM?
