(This review was previously posted in my main review page, Goji-Fi on Facebook. Thanks!)
Greetings!
This IEM marks the debut of this audio review page, Goji-Fi!
KZ Official Store 's KZ CRN is a hell of a way to kick off a series of proper reviews of IEMs that I have here in my possession and those I have yet to acquire.
Every review here in Goji-Fi will be split into 3 parts for maximum simplicity:
- Packaging (Presentation, Product, and Particulars)
- Build Quality
- Sound (Signature and Soundstage)
In Godzilla fashion, each part will be graded by Atomic Breaths (
). Grading scale will be from 1-5 Atomic Breaths, following the typical 5-point numerical grading system (1-Poor, 2-Below Average, 3-Average/Acceptable, 4-Good, 5-Excellent).
As a bonus, I will be providing a 𝘎𝘖𝘑𝘐-𝘈𝘗𝘗𝘙𝘖𝘝𝘌𝘋 𝘗𝘈𝘙𝘈𝘔𝘌𝘛𝘙𝘐𝘊 𝘌𝘘 𝘚𝘌𝘛𝘛𝘐𝘕𝘎𝘚 that are either recommended by the community and/or home-brewed by myself. Home-brew EQ settings are of my personal and subjective taste, playing by both the strengths and weaknesses of the IEM. These will respect the original sound signature and sonic vision of the IEM.
Let's start!

- Presentation
The box is of typical Knowledge Zenith fashion and dimensions. It comes with a minimalist white box KZ is known for, with some excemptions: KZ and Crinacle's logo are present in the top left corner, the full picture of the IEM on the center (a departure from the silhouetted presentation of the IEM inside), and the text "KZ x Crinacle CRN" highlighted. Technical specs are found at the back, more logos and information are seen at the sides.
- Product
Once the slide-on paperback cover is removed, we are presented with the KZ CRN on full view. It is still denoted as the ZEX Pro, as it is technically the same IEM. It is protected by a thin acrylic plastic, which has a small notch for convenience of unboxing.
- Particulars
A small baggie of eartips (S & L) are included, with the M sized tips already installed in the KZ CRN. Next, a white tapered cable is included, which is a departure from the past braided style cables KZ used to provide with their IEMs. Its equipped with the new KZ standard QDC ends, which promises increased protection of the 2-pin connection and a more snug fit to the IEM.

The build quality for this IEM is fantastic considering its price. It feels hefty and valuable, without it being too weighty for it to be uncomfortable to be used as an IEM. The faceplate is made of metal, with an option for a black or rose gold paint scheme. This gives the IEM most of its heft and durability, although there have been reports of paint chipping occuring after months of usage. KZ should address this situation through better methods of painting their metal faceplates, as it can be a caveat for those looking for long-term stylish IEMs. The back of the IEM is made from a medical grade resin material, that of which makes sure that skin irritation is kept to the minimum. The included cable is an upgrade from the previous bronze/brown-ish braided cable KZ used to include in their IEMs, which usually tangled LIKE HELL for me. This one almost never tangled for me, and it provides a proper complement to the heft of the IEM itself. The eartips are well, the standard KZ Starline eartips, only in a new color. I won't speak for it as they're honestly crappy for me, I would recommend to use other tips you have in your inventory.
KZ has allegedly analysed thousands of ear shape samples to create the shell of the KZ CRN, and it shows. Comfort in my ears is superb, the protruded fins properly secures the IEM on the inside. However, this can be a caveat for those with smaller and/or peculiarly shaped ears, as it can definitely cause pressure when fit is not shaped for said ear types. I can confidently say that I can wear this IEM for hours on end, but I can't speak for those who unfortunately cannot.

- Signature
Surgically-precise. These words are what describes Crin's tuning for these IEMs. Every song comes through as very clean in presentation, but not too clean that it sounds sparkly clean. Everything is laid down in equal proportions, like a Mama and Papa Bear serving the proper portions of porridge for their cubs.
The low bass extension that Crinacle put into these provides a little bit of spice and identity to the surgical nature of these IEMs. Despite the rumbling low bass features, bassheads might be a underwhelmed by the lack of the mid-bass thump that they crave.
KZ's in-house sound signature that scoops the mids for more bass and treble are definitely NOT present here, as mids are clear as day. This gives the bulk of the IEM's body, as the non-recessed mids gives that oh-so meaty mids that I personally love. I personally love stoner metal music; the luscious layering of guitars are felt and heard, oozing out like a juice from a freshly-barbecued steak.
With all the praise I am giving, we come to the point wherein problems start for this IEM: the treble region. Its infamous 8K peak is currently doing its rounds around the community, making it a point of contention whether to buy the IEM or not. I kid you not, I CAN definitely hear this peak. Sibillance is immediately heard because of this peak, which can hurt treble-sensitive ears. It gives off a weird tonal imbalance to the otherwise-surgical approach of this IEM, making it sound metallic and cold. Maybe KZ and Crin were thinking of surgical knives when they tuned this one, hehe. If you're asking if this peak is enough to be warranted as a dealbreaker, fear not, it isn't. Its a weird feeling, as if its MEANT to be there to peculiarly compliment the neutral tuning they were trying to achieve with this one. After a period of adjustment and *supposedly* Crinacle-approved EQ fixes, the sound signature becomes a wonder to behold in the Chi-Fi budget range.
- Soundstage
KZ's limitations are also seen in this one. Those who are expecting an expansive sound will be disappointed. The soundstage is in-face and intimate, which compliments the straightforward, no-shrills presentation of the KZ CRN. Resolution is OK, which is expected at the price range. Imaging is average, as if it feels like there are two separate stereo images for each ear, with a recessed presence on the front. Drum tom rolls sound strong from the left, lose its volume in the front, then come back out strong on the right. I've had better imaging from other IEMs on this price range.
