NICEHCK NX8 Review: 8 Drivers, "Old Meta" Tuning, and a Surprising Lack of Sibilance
This is my first time writing a review for an IEM in this price bracket (the $200 range). To give you some context, I'm writing from Brazil, where high import taxes and a volatile currency make gear at this level extremely inaccessible for most of us. I managed to snag this unit through a trade for several of my lower-tier sets, so being able to finally experience something in this category is a big deal for me.
In the international market, it usually goes for around $190 - $210 USD on AliExpress. It’s a competitive price point, filled with heavy hitters, but the NX8 definitely brings something unique to the table.
Technical Specifications
Drivers: 1 Dynamic Driver (Bass) + 6 Balanced Armatures (Mids/Highs) + 1 Piezoelectric Driver (PZT for ultra-highs)
Impedance: 12Ω
Sensitivity: 110dB/mW
Cable: High-purity silver-plated copper, 0.78mm 2-pin
Shell: Medical-grade resin
Build and Comfort
The NX8 is a looker, but what really blew me away is how it just "disappears" in the ear. With 8 drivers per side, I was expecting a massive hunk of resin, but honestly, I have no idea HOW they managed to fit everything in such a small shell. It’s incredibly comfortable, lightweight, and the anatomical fit is spot on.
A quick shout-out to the accessories: the NiceHCK C05 liquid silicone eartips are fantastic. They are super soft, don't irritate the ear canal, and provide a grippy seal that helps maintain the bass response without sacrificing comfort.
Tuning and Sound Signature
The NX8 was released about two years ago and follows an "old meta" philosophy. It ignores the current trend of JM-1 or Harman-target-everything that’s flooding the market right now. It focuses on a classic neutral-ish profile but with a very tasty and present bass boost. It’s an addictive signature that keeps you coming back. A nice reminder that we don't always need to follow the latest tuning hype to enjoy great sound.
Bass
The bass here has authority but remains well-controlled. You get that deep sub-bass extension that lets you feel the rumble, though the main focus seems to be on the mid-bass. The result is a punchy, "clean" impact that gives body to the music without sounding bloated. However, on some tracks, the bass can bleed slightly into the lower mids, making the sound feel a bit "muddy" or congested. It’s not a dealbreaker, but if you’re looking for clinical separation between bass and vocals in busy tracks, you might notice it.
Mids
The mids are smooth and very natural. It’s not an aggressive "in-your-face" presentation, but the vocals aren't buried either. There's a tonal coherence here that’s hard to find in high-driver-count hybrids. String instruments and pianos have a very realistic texture, avoiding that "metallic" BA timbre that usually causes fatigue after 15 minutes.
On the flip side, I did notice a slight "honkiness" or nasal quality in the vocals occasionally, depending on the recording. It’s a minor timbre quirk that doesn’t take away from the overall technical performance, but it's there.
Highs
This was my first encounter with a Piezoelectric (PZT) driver, and it surprised me. There’s something different about the treble here that’s hard to put into words. It reaches incredible extension in the upper frequencies without ever becoming sibilant. For someone like me who is sensitive to treble peaks, this is a godsend. It’s smooth but detailed.
That said, if you’re a "treble head" looking for extreme "crispness" or tons of air, you might find it a bit too safe. It prioritizes a relaxed, musical listen over aggressive micro-detailing.
Technicalities and Performance
For Metal, Post-rock, or Jazz, the performance is exceptional. The driver speed is impressive, especially during fast drum transitions or complex experimental passages. The soundstage is quite wide, and the instrument separation is well above anything else I’ve used.
I’ve read some reviews comparing it to rivals like the AFUL Performer 5+2, suggesting the NX8 might lag slightly behind in pure resolution, but since I haven't heard those, I can only say the resolution here is already very impressive for my ears.
Albums with high speed and technicality, like the deathcore masterpiece 'The Poetic Edda' by Synestia, sound surprisingly effortless. The NX8 stays fast, doesn't get congested, and delivers great technical resolution while keeping that signature smoothness.
Conclusion
The NiceHCK NX8 has officially become my favorite all-rounder. It handles almost any genre with competence. It’s the perfect IEM for someone who wants a refined, technical sound but refuses to deal with ear fatigue.
It has its flaws, like the occasional nasal mid or the slight muddiness in the bass, but the overall package is incredibly strong. It doesn't try to "wow" you with artificial peaks; it wins you over with naturality and authority. If you want a "one and done" IEM for long listening sessions, the NX8 is a solid recommendation.
