The Big New Year’s Update: The Insignificants

AKA: I mass-dump all average IEMs into the ranking list

I’m someone who tries a lot of stuff as I go along. IEMs for sure, but headphones too, and other source-level components if I’m curious. And regardless of what other reviewers may tell you, a huge chunk of them are… average.

To be fair, that’s the whole definition of “average” in the first place. You need the Average Joes to exist in order to contrast with the true blue Brilliant Bruces, else the term “better than most” just loses its lustre. After all, a weird troll doll once said: “when everyone’s super, no one will be“.

These are the entries that I feel no desire writing more about. They are average (or lower) in my own definition, and so makes them even harder to write for. I have the linguistic capacity to praise the greats and admonish the scum, but what about everything else in between? Those are the hardest things to write for, and I find myself in the worst kind of the writer’s block every time I’m obliged to write something about them.

So I say, skip it all. No point locking these Insignificants away in the Patreon vault forever, so I’ll just dump them all in the ranking list right here, right now.

Perhaps the word “Insignificant” is a little too heavy-handed to describe some of the following IEMs considering that they may be average-sounding, but priced so cheaply that they create their own value. But at the end of the day, they aren’t exactly great in their own right but rather great in terms of their price tags.

The following table is arranged according to the grade awarded.

Unique Melody Mason V3+A-3200Bright neutralDecent resolution, nothing really special otherwise.16BA

  1. It feels rather insulting to see the Shuoer tapes on that list, considering I just made the conscious decision to shed a quarter of my biweekly salary to buy them…

    1. Maybe this hobby isn’t for you, if you have so little disposable income. The tape isn’t particularly well regarded, and crinacle isn’t here to make you feel better about your purchases. He posts his own personal analysis and you can take that however you want.

  2. Seems that the most insignificant one is the reviewer.
    In your top ranking only very costly iems…
    And so much iem tested in so little time by the same person makes your reviews irrelevant IMHO.

    1. I’m sorry that I didn’t like your favourite IEM, whatever it may be. I hope your feelings aren’t too hurt.

      1. At the end the goal of this site is to generate money and income for the publisher. So mixing in some disputable reviews helps to reach this target – this is normal nowadays.

        If the reviewer has good ears or not, good taste or not means nothing, only traffic sells.

        And you will see this note will vanish at the blink of a eye, don’t help to make money ;-).

        So, what do you think, is this a trustworthy source?

        1. I’m assuming that something I panned in this article was something you liked. If you want to read positive reviews, better find a different review site.

  3. oh look at the tears of the fanbois here who spent their money on the gear listed trying to downplay the review and reviewer. salty tears are nice.

    As for the guy who claims that only expensive stuff is ranked high, theres a couple of bargains on his list- including the one i personally own, s8pro. At sub 500 dollars, its a bargain and Crin ranks it high deservingly so since its sound matches up great to some of the reallly expensive stuff on his list. So yeah Crin doesnt mince words. He panned some expensive gear even from the most known companies.

  4. Wow, actually I was considering the Equinox as my first High end Custom IEM. The only prospect that held me back was the insane price tag, now I got another reason to look elsewhere.

  5. im buying audio sense t800 and i really appreciate crin criticism which makes me aware what im facing when i buy it. Also, crin said about t800 is nothing special and generic and its v-shape, to me thats great because i listen to generic songs a lot lol and its jack of all trades. He didnt say its bad so thats encouraging, because im buying it for the look too, its looks nice.
