KZ - ZSN PRO 2

I'd personally go for the KZ ZSN PRO 2 as it has a similar tuning to the KZ ZS12 PRO X, which in my opinion it great for gaming and music. That said, it also depends on the music you listen to.

Hey everyone, I wanted to share something truly crazy that happened to me. Recently, I bought a pair of KZ ZSN Pro 2 from KZ Globol Store on AliExpress (yeah, it’s spelled "Globol" lol). I ordered the ZSN Pro 2 without a microphone, but they arrived with a mic instead. That wasn’t the important part — the real surprise came when I started listening to them. Right out of the box, something felt special. The sound wasn’t just “good”; it was shockingly immersive and technically impressive. Here's what I noticed: Vocals are extremely present, with a clear, full-bodied yet silky and transparent texture — you can feel both the "weight" of the voice and its fine detail at the same time. Every instrument is perfectly placed around you, with an almost orchestral-level separation. Absolutely insane imaging. I can point exactly where each sound comes from: left, right, front, or even a bit behind. No real sibilance: S-sounds are slightly bright and energetic but never harsh or painful. Midbass is punchy and very well controlled, never bleeding into the mids. Treble has a lovely airiness and sparkle, with tiny details everywhere, but never causes fatigue. The soundstage feels genuinely wide — about 4 to 5 meters in perception, which is something rare even among much higher-end gear. I listen mostly to pop and rock (both hard rock and indie), and these IEMs made it a whole new experience: Songs like "Chicago" and "You Rock My World" by Michael Jackson completely blew my mind. I could hear every backing vocal, guitar, bass lick, or tiny percussion element placed exactly where it should be, something I usually expect from high-end headphones. I tested them at around 70% volume for critical listening (louder volumes around 85% didn’t cause distortion either!). I also used Dolby Atmos in Music Mode on my phone, but it was minimally affecting the mix — the sound magic was purely the IEMs. --- Then it gets crazier: I got curious and inspected them physically. The BA driver inside my set is labeled A30019 on one side and KZ 30019 on the other. A30019 is a real, legitimate Knowles-type BA used in KZ’s more expensive models (like the ZS12 Pro X that has 5 BAs + 1 DD). Not the typical tiny in-house BA used in cheap models. Also, the dynamic driver seems very different: Comparing it visually to my other IEMs (like my KZ Castor Improved Bass), it looks much smaller, probably around 8mm instead of the usual 10mm. There's even visible space (about 4mm) between the driver and the metallic shell inside, which is very unusual for KZ builds. It suggests that either a different DD was used or that this batch had some experimental tuning choices. The physical build: Overall solid and premium feeling. The 2-pin connectors fit much more firmly into the shells compared to any other KZ set I've owned (including Castor and EDX Pro). --- I did frequency testing too: Using a sine wave generator, I found: Around 2.5kHz, the sound noticeably becomes stronger and sharper. Between 3kHz and 6kHz, the intensity dips slightly (still detailed though). Then after 6kHz, the energy rises again, giving that airy, clear treble. This behavior is typical in high-end tuning where they manage to tame peaks while keeping clarity. --- Authenticity concerns? I know, this sounds too good to be true, right? I double-checked: They came with a normal KZ barcode on the box (no QR code, but that’s becoming more common in newer KZ batches). They sound WAY better than any fake KZ I’ve ever heard about — genuine functional A30019 BA inside (fakes usually just fake the name, not the performance). Bought directly from KZ Globol Store on AliExpress (which matches where I bought my Castor Improved Bass too).

Zsn pro 2 is good, but not the best.

If it is a new revision, then I have the og. It's nice and balanced but have some piercing highs sometimes

Just looked at it rn and it doesn't seem to have a ba number on the driver. I can't look more on detail on it since now it's of my sis but I'll check it tomorrow

I know, and my PRX I got it for even cheaper (26$) so it was a must. Loving the new KZ, tried the earlier "new tuning" with the ZSN Pro 2 and honestly there were glimpses of what was about to come. Glad it turned to be good

My 1st IEM was KZ zsn pro 2. It's still working fine, although I don't use it much. It has a sharp treble compared to my other IEM. Nowadays, I use it for taking meeting calls as due to high treble, the voice is very clear in this IEM. And for listening to music, I mostly use Nova or Aria 2, depending on mood.

I also bought this kz zsn pro 2 iem and i can confirm that the soundstage is great, i played hogwarts legacy and i couldn't belive cuz it was similiar than my philips shp9500 openback headphone! But i only use the kz for gaming cuz tbh for music listening it's a very mixed bag and it does not work for like 1/3 of my playlist cuz the treble sometimes is a bit too harsh and can mess some female vocals. For music i use a tangzu fudu with -1.5 dB on bass and the soundstage is almost as good (the 2x ba is way better tunned than on kz) without any harshness and def better than my zero red. You can check Paul Wassabi review where he praise this iem for soundstage and airy treble but he also sometimes got harshness so i don't think you got something special maybe our taste or hearing are different (i'm treble and upper mid sensitive). https://youtu.be/JwY8h6b_RT4?si=dIzIVl80lK4k5_Ij

I have bought a lot of cheap kz and the kz zsn pro 2 is really good is above every one on the same price range I prefer it even above the waner sg 2

I have the kz zsn pro 2, and love it ! great price, and great sound. i got mine in Amazon Mexico, around 25 dlls.

Kz Zvx pro, kz zsn pro 2, cvj night elf, kz vader highres, trn v10 pro, trn v90 pro... The mt5 is all but analytical, is a reshell of the Orca but bad tuned lol.

I bought mine (ND planet) a few days ago so I'm waiting it to arrive the next week maybe?, the Orca is very capable in technicalities, but is not better than the V10 pro in this aspect, ZVX pro is a beast in technicalities maybe trading blows with the Vader HighRes (but the Vader is just in another league, is almost 90% of the CCA Hydro), maybe on pair with the V90 pro and Nightelf, and the ZSN pro 2 is perhaps the only on pair with the Orcas, but with a little more stage and imaging. Btw, i love my Orcas, and i hate my mt5, i know I'm crazy but whatevs ahaha. Cheers mate!

In this price range i think the 7hz Zero 2, KZ ZVX Pro, KZ Vader Balanced, CCA Trio and other gems, the 7hz is a conditional rec, is not for beginners, umm, the KZ ZSN pro 2 is also a nice rec. I think the BL03 II punches above its price, is trading blows with my Inawaken Dawn ms an Kefine Klean, is a iem who worth its price. The other color offered is clear silver, is beautiful. The DUNU dtc480 is driving even my hungry planars so well... Of course is more than enough for the BL03 II, the cirrus logic chip is excellent, the sound it produces is uncolored, so natural, so faithful to the music, is a very analytical dac/amp
