Extreme basshead's dream. Incredible sub-bass shelf while maintaining midrange and treble balance. Precogvision Youtube Channel
Fatfreq Maestro Mini reviewed by: Jays Audio
A basshead set that's actually well-balanced for the most part. Extension on uppermids/highs are good but can get shouty, sub-bass texture and slam is impactful and satisfying - this is the set for most bassheads who don't want a crap ton of bass but still a good amount. Deuce better. Jays Audio Youtube Channel

2025-09-03Trebble so nice. Feels faultless and amazing. Jaytiss Youtube Channel
NiceHCK Rockies lands in the ~$500 bracket with a 1DD+2BA+2EST setup and a surprisingly premium package. The hollow resin shell feels solid, with a metal nozzle, slightly recessed 2-pin, good isolation, and comfy fit. The swappable-termination cable is thick, pliant, and lays flat—no chin slider out of the box, but easy to add—and the excellent case and tip kit push the accessories into “above class” territory.
Tonally, Rockies goes for tight, controlled bass and a natural midrange, capped by upper-treble that’s sparkly yet refined—detailed without getting shouty or brittle. The graph reads largely flat with a tasteful treble lift, translating to a clean, clear presentation that stays engaging rather than fatiguing. It comes across as an “instant classic” tuning: lively, airy, but still grounded.
Compared with brand siblings (DB2 too upper-midsy; F1 Pro/NX8 fine but not special), Rockies feels like the step up. Versus peers, it splits the difference: more air and delicacy than RSV MK2 (which is bassier/darker), less sizzle than sets that chase treble for effect, and broadly similar endgame vibes to “good” units of Mega5-EST—variance there being the rub. Net: a high-value pick at its price, worthy of a Gold Star—not a universal “benchmark,” but a sweet, natural, clear listen that many will prefer, especially with the standout accessories.

2025-09-09My favorite take on the JM1 meta so far. Bass tuning is well done with adequate weight and punch - it's not standout but it will do the job. Silky smoooooth and rich mids with very good clarity. Treble that leans slightly bright but is never sharp. Very good transient response, especially with things like plucking sounds and the like. Renders strings very well. Some people might find the treble a bit forward but I don't personally find this to be an issue, except on certain tracks. It's an IEM that is hard to fault and one that will handle anything you throw at it well. Very suitable as a one-and-done IEM. Previously Owned

2025-08-28Balanced, clean, airy, with a slight treble emphasis, good EST implementation, great overall package and accesories at the price. Similar to TOP PRO but with ESTs and not as vocal centric. Easy rec if you want something balanced and airy. Jays Audio Youtube Channel
The NiceHCK Rockies have a balanced tuning with standout treble extension from its ESTs. Vocals are tamer with a cut in the upper mids, trading sparkle-forward presence for a smoother, airier presentation; staging feels more open because bass and vocals sit slightly back, while cymbal decay lingers with a pleasing airiness. Technical performance is very good for the price—punching above many $500–$600 peers—and the unboxing/accessories package adds to the overall value.
Low end is grounded and tidy rather than slammy; texture and separation are solid, but this isn’t for bassheads or those wanting vocal-forward excitement (sets like Top Pro or Volare cover that better). The Rockies excel with rock/metal/indie/classical where the extra air, layering, and controlled upper energy shine; they scale best at mid volumes, and tip rolling should avoid options that over-boost or dull the treble—the stock tips already hit a sweet spot. Net: a confident recommendation at ~$500–$600 for listeners prioritizing treble quality, detail, and spaciousness, with the main trade-off being a more restrained bass and laid-back vocal emphasis.

The NiceHCK Rockies is a five-driver tribrid using 1DD + 2 Knowles BA + 2 Sonion EST in a resin shell with Pietersite stone faceplates. Specs list a detachable 0.78 mm 2-pin cable with swappable 3.5/4.4 mm plug, 9.8 Ω impedance and 121 dB/Vrms sensitivity, indicating easy driveability from portable sources.
Early third-party coverage characterizes the tuning as neutral with a sub-bass lift and smooth, controlled treble, with 5128 measurements available via Crinacle’s public database and a review on Hangout’s channel. These impressions emphasize strong imaging and detail without obvious harshness when recordings are clean.
At an MSRP of $499 (with a short launch price of $469), value hinges on preference for an energetic, U/neutral-with-bass presentation; listeners sensitive to upper energy may find mids a touch lean on certain material, as some impressions note. In short, Rockies trades a warm mid focus for sub-bass reach, treble resolution, and a stable stage that suits modern pop, electronic, and large-scale orchestral.
