Ha, your two posts in this thread have been entirely an expression of you being rubbed the wrong way for some reason, with zero content about the 7Hz Zero (or even anything related to audio) at all. I however have pointed out the poor build quality of this IEM, posted the results of research from an esteemed acoustic scientist that IEM sound quality has no correlation with price, and given a counterexample with measurements to the mistaken belief that 'universal praise' in sighted listening prone to cognitive bias necessarily means good sound quality, both of which are myths pervasive in this hobby that I'm cautioning against.
Just because there might be no correlation, it does not mean that a well-informed individual is not interested in paying less for better audio quality (obviously).
So it still does make sense to say things such as "it sounds good for its price".
That said, personally I still think that it does not only sound good for its price. I see it as an overall good sounding IEM. Not perfect, not the best by any means, but good.
If I were a billionaire and price would be completely irrelevant to me, I would not buy the 7hz Zero. But I do think that I would prefer the frequency response of this IEM over the vast majority of IEMs at any price point.
And I would not even say that this is entirely subjective. The 7hz is not very close to the Harman target, which is closest to an objective (intersubjective) benchmark. But what can be seen on any graph is that the 7hz Zero has a good peak and dip performance, which I consider important. I consider a Harman-ish IEM with a bad peak and dip performance as worse as an IEM which doesnt try to reach Harman but is coherent in its goal. The 7hz Zero performs its warm-neutral signature well, and most people who are looking for this kind of signature will probably like the Zero (like me).
Critisisms of the 7hz Zero I agree with include channel matching (still good for its price), product variation, the one-noteish upper treble and arguably the typical single BA driver downslope from 300 to 1000hz. So yes, it is not perfect and there are more expensive IEMs who perform this kind of signature slighly better. But they are still good in my opinion (at any price).
Besides, I dont think the case you posted is enough to claim that the build quality of the 7hz Zero is bad
for its price. Of course it makes a huge difference if an IEM for 25$ might break early or an IEM for 2000$. The risk calculation is completely different.
And one thing I
do feel able to judge is the build quality of the Zero as long as it works as it is supposed to do. And as I said, the stable and hardly microphonic cable really exceeded my expectations. Even if this IEM should break in 6 months - I dont expect it to happen - the value for money would still be okay.
