Reviews Comparison
Aful Cantor reviewed by Jaytiss
The AFUL Cantor delivers a balanced and neutral sound signature, praised for its exceptional upper air, treble extension, and pristine clarity. While the bass offers sufficient dynamics without being thunderous, and female vocals sound natural, some listeners might desire a touch more punch in the upper mids (around 2-3kHz) and find a slight peak in the 4-6kHz region occasionally noticeable. The premium build quality stands out, featuring a unique and stunning "star night" face plate, a thick but comfortable shell with a slender nozzle, and excellent accessories. These include a slightly microphonic but otherwise nice-looking flat two-pin cable and an exceptionally plush case typically found on far more expensive IEMs.
Graph comparisons reveal the Cantor's tuning shares similarities with models like the Moondrop Blessing 2: Dusk and the AFUL Explorer, but it distinguishes itself with superior detail retrieval and dynamics. It competes impressively against significantly pricier offerings like the Elysian Annihilator in technical performance, offering a smoother presentation with slightly less sub-bass focus. The overall sonic presentation is described as sophisticated, refined, and highly engaging, creating a sense of music surrounding the listener. Minor tuning preferences aside – wishing for a bit more upper mid presence and slightly less energy around 4-6kHz and 8kHz – the core sound quality is highly regarded.
Representing strong sonic value despite its price point, the Cantor earns a high ranking for its unique and beautiful design, premium feel, and exceptional technical performance. While acknowledging excellent cheaper options like the AFUL Explorer exist, the Cantor justifies its cost with its detailed, airy presentation and overall package. It's highly recommended for those seeking a neutral, high-performing IEM, though a demo is advised given the investment. Ultimately, the AFUL Cantor is considered a treasure, fulfilling over a year of anticipation with its beautiful aesthetics and uniquely engaging sound.

2025-09-03NiceHCK 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.

The Aful Cantor presents a complex and frustrating case, offering what might be some of the most detailed and resolving performance under $1,000. The clarity, separation, and sheer resolution are described as "pretty nuts," positioning the Cantor as a potential benchmark for technical ability. It delivers a clean, smooth, light, and airy sound signature with a bass that is very fast, lean, and features a tight sub-bass rumble. At lower volumes, this presentation is highly enjoyable and non-fatiguing, making it exceptionally good for critical, quiet listening sessions where its technical prowess can shine without drawback.
However, this technical marvel comes with a significant and unusual caveat: it is physically fatiguing to the point of causing headaches and a ringing sensation in the temples after only 15-30 minutes of listening at moderate volumes (around 70-80 dB). This is not a fit or nozzle issue, but rather an inherent property of the IEM itself. The problem manifests as a shrill and overly intense quality in the treble at higher volumes, accompanied by a metallic timbre on tracks with lots of cymbals, making it unsuitable for energetic genres like K-pop, J-pop, or EDM. This shrillness is not fully solved by EQ and is believed to be related to the driver design, nozzle, or venting rather than just the tuning.
When compared to peers, the Cantor is more resolving than the warmer, fuller, and smoother Letshuoer Supernova but falls short of its natural timbre. It also can't match the Monarch MK3 as an all-rounder, which offers a more impactful bass, better vocals, and a smoother, more engaging experience. The Cantor's vocals are also a weak point, being recessed, light, and borderline thin. The final recommendation is to definitely demo these first; they are only easy to recommend for those who listen at very low volumes (under 60 dB) and are not sensitive to treble intensity, as its scaling at normal listening levels is poor.

2025-08-28The 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 AFUL Cantor lands as a flagship all-BA set with 14 balanced armatures at $800, packaged with a great-handling nylon cable and a handsome shell. The catch is fit: a very long nozzle with a metal insert demands a deep insertion, and comfort varies widely; AFUL’s stock tips are essentially required to keep that nozzle from poking and to restore some flex. Build and presentation impress, but the ear-fit can be fussy and the shells tend to stick out.
Tuning trends U-shaped: a lower-mid dip into a hefty sub-bass boost, relaxed upper mids, and noticeable upper-treble energy. When seated correctly, the set delivers crisp transients with a touch of “planar-like” pluck, good imaging, and clean BA bass that favors electronic thump over kick-drum slam; with the wrong tip or depth it swings to brittle/bright or muted. The midrange can read a bit thin, so the contrast comes more from bass/treble edges than from vocal saturation.
Compared with Symphonium Helios, both are all-BA and graph-adjacent, but Helios leans vocal-forward and smooth while Cantor is the more contrasty, fun listen that trades mid presence for excitement. Net: technically capable and competitive when dialed in, yet compromised by comfort and tip dependence. Final verdict: 3/5 stars—a better match for listeners with deep pockets and deep ears.

2025-09-13NiceHCK Rockies lands as a $500 tribrid (1DD+2BA+2EST) that mirrors the Mega5-EST’s tuning with subtle tweaks. The unboxing is generous—three styles of tips (including AET07-style and tacky “medical” silicone), a large puck case, and a swappable 3.5/4.4 screw-lock plug. Build feels premium with a real pietersite stone faceplate; fit is comfortable but shell geometry is generic, so stability depends on tips. The stock cable looks nice but is stiff and, notably, has no chin slider.
Sonically, Rockies follows a tilted diffuse-field / “new meta” balance with slightly less bass and a touch more lower-treble than Mega5-EST—on the order of ~1 dB each way. That shift tightens the low end and improves separation/imaging, making the set feel more technical; however, it also trims warmth and depth, leaving the presentation a bit dry/brittle at times. Bass quality is clean and controlled rather than showy; treble reads clear without obvious harshness on the 711 rig readout, though it can edge lean.
Against peers, Mega5-EST stays the easier, warmer listen with slightly “thuddier” bass, while DUNU’s Brain Dance is the pick for maximum excitement and staging (more clinical up top). Moondrop x Crinacle Dusk (analog use) offers stronger imaging and notably satisfying bass execution at a lower price. Rockies ends up a very good, balanced all-rounder that some will prefer over Mega5-EST for its tidier bass and clarity, but the trade for brightness and dryness is real—final verdict: 3/5.

This is AFUL’s flagship science project: the Cantor packs 14 BAs per side (28 total) and a heap of buzzword tech—Dual-Channel Acoustic Maze for sub-bass, non-destructive direct-drive topology, and multi-dimensional crossover trickery that reads like Star Trek schematics. The housing even extends a stainless-steel nozzle to the tip’s end to bypass tip coloration—smart for consistency, dicey for ears with wide-bore silicones. Stick to the stock silicones or better yet foams to calm treble and avoid any scrape-risk.
Sonically it’s a hyper-resolving analyzer: every band is so present that volume tends to go down, not up, and mediocre recordings get roasted on the spot. Imaging is precise but a bit less cohesive than simpler sets; stage stays as the track dictates, while separation feels like a mixing desk with 14 faders. The sub-bass dives shockingly deep for an all-BA—think whisper-low “whoomp”—yet it isn’t a bass-monster; overall balance leans revealing rather than lush.
Pairing matters: clinical amps make it razor-edged, while warmer sources (R2R, iFi, RME-ish) and foam tips smooth it into addictive detail. At $800 it isn’t the one IEM to rule them all; it’s the specialist tool for listeners who want to dissect space, mic technique, and mix decisions—more control room than mosh pit. Cable and case are solid (4.4 mm balanced), and a tuning switch would have been nice, but for the right kind of nerd this thing lets you become the squig.

2025-09-26Tonally, Rockies follows JM1’s safe neutral-ish slope but with leaner mids and brighter treble. Bass is punchy, quick, and well-controlled; mids a touch dark but cleanly separated; and treble opens into airy, effortless EST sparkle with no sharp edges. Stage has decent depth over width, resolution solid for the price, immersive enough without grandeur.
Verdict: not flawless (could use more sub-bass reach, meatier bass, thicker mids, and wider stage), but well-executed overall. A satisfying, balanced tribrid that showcases EST treble gracefully without breaking the bank.
NiceHCK’s new flagship Rockies is a tribrid tuned for modern detail: 1DD+2BA+2EST under $500, clearly squaring up to Hisenior’s Mega5. The build pairs a black resin shell with a real-stone Pietersite faceplate—distinctive without feeling flashy. The headline quirk: extreme sensitivity to source output impedance. With higher-OI sources (laptop/24Ω interfaces) the bass explodes into a clubby boom; with a low-OI dongle (e.g., <2Ω like FiiO KA13) the tuning snaps into place—tighter lows and balanced overall. Measured on a B&K 5128, the Rockies’ “properly driven” curve mirrors the original JM1 through upper mids and treble, then adds a narrow 14kHz lift for extra air and sparkle.
Once driven correctly, bass turns punchy, clean, and disciplined—impactful without bleed, earning a confident 4.5/5. Vocals image with razor-edged precision and a slightly darker hue, yet remain well-separated; treble flows smoothly with EST-powered extension, no harshness or sibilance, and even opens further after some burn-in. Resolution and depth layering impress more than width—the horizontal soundstage sits about average for the price. Wish-list tweaks would be a touch deeper sub-bass, a hair brighter mids, and a wider lateral spread. Overall, Rockies feels like a thoughtfully executed, source-dependent tribrid that rewards a low-impedance chain with a balanced, detailed, and satisfyingly airy presentation.

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.
