KZ - ZSN Pro X Series

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.

I find mines very comfortable. I could wear them for +2 hours without much discomfort compared to other iems I got ([ZSN-PRO](https://www.aliexpress.com/item/1005002438769452.html) & [KZ ZEX Pro](https://www.aliexpress.com/item/1005003589418259.html)) They're also a bit smaller so that might be why.

I was just about to order blue 2 😭😭😭 i have kz zns pro 2 now

My previous IEMs were KZ ZSN PRO, and the difference between them is like night and day.

I use zsn pro x they are extremely cheap and the quality isnt great for watching movies but damn does it make a huge difference on the surround in this game

Beloved shanling up4 + iems, kz zsn pro 2 for anything casual + earplug for daily motorcycle commute

This game has amazing mixing and IEMs or studio monitors are the way to play it. I game on my Sony MDR and I’ve noticed that my friends who use gaming headset can’t hear shit because the bass boosts hides a bunch of sound ques. If cost is an issue I recomend KZ ZSN pros or really anything by KZ they’re top tier cheap IEMs. I do recommend find one with a longer wire with mic built in.

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).

I have these but I found them a bit harsh in the top end and bass was lacking a bit.

I use the KZ ZSN PRO X along with the KZ M2 cable. its really good.
