Youtube Video Summary
Bass is where the Monarch MK3 steals the show: tight, textured, and rumbly with real slam and no bleed, giving male vocals a more natural heft while staying clean. The Prestige LTD pushes the low end back for a lighter hit but trades that for a more open, airy stage and superior layering—great for busy mixes like rock, metal, and classical. The Hype 2 mirrors the LTD’s bass balance and rumble conceptually, but lacks the same overall technical resolve, making the MK3 the better pick for pop, EDM, R&B, and hip-hop that benefit from weighty sub-bass.
Through the midrange, the LTD steps ahead on separation, detail, and note definition, presenting vocals slightly set back yet more airy and sparkly; female vocals especially shine. The MK3 counters with more weight and engagement on male vocals and a forward presence, though its stage isn’t as deep or spacious as the LTD (a modest vertical lift over Hype 2, but not a “$1k soundstage”). Up top, the LTD has the smoothest, best-extended treble with the most air and microdetail of the trio. All three excel at moderate volume, but none invites cranking like certain high-volume specialists.
As an all-rounder, the MK3 checks nearly every box yet misses that distinctive “special sauce” expected at its price; think ~15–20% uplift over Hype 2. The LTD delivers the bigger technical jump at roughly 25–30%, with staging, extension, and air taking the crown, making a strong case paired with a cheaper daily driver. The Monarch MK2 still earns a nod for its midrange/vocal magic if that’s the priority. Final word: both LTD and MK3 score an S; for those willing to spend, they’re easy to recommend—just match the tuning to the library and the qualities valued most.

Youtube Video Summary
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.

Youtube Video Summary
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.

Youtube Video Summary
Thieaudio Monarch MK3 takes the flagship slot with swagger: a 2DD + 6BA + 2EST array and a 4-way passive crossover, centered on the Impact² isobaric push-pull dual 10 mm subwoofer. The shells are huge and gorgeous (plain backs at ~$1000, fancy backs around ~$1100), vented on the underside, and paired with a supple, interchangeable-plug cable (2.5 / 3.5 / 4.4). Despite the driver count, coherence is the headline: this isn’t a parts parade—it’s a single, surgically precise instrument.
Sonically, bass behaves like a well-tuned subwoofer in a treated room: tight, fast, and slammy without bloat. The real party trick is imaging and spatial “distance”—sounds lock into place with eerie specificity, making familiar tracks feel new. Instrument separation is crystalline, treble air is effortless, and the set is easy to drive yet scales—more power refines rather than merely getting louder. Tip rolling matters: stock foams/silicones are okay, Dekoni helps, Dunu S&S can fit oddly on these large shells, while Render tips seal the room and boost performance ~15–20%, supercharging the imaging and engagement.
Against the Monarch MKII (good, kept around), the MK3 feels like a different tier—the sort of tuning that glues ears to music and makes skipping tracks impossible. Accessories are minimal because the message is clear: you’re buying the sound, and it arguably feels underpriced for this level. Currently on pre-order, this is peak IEM energy—an endgame-grade, king-making performance that invites hyperbole and earns it.

Youtube Video Summary
Thieaudio Monarch MK3 steps up as a true flagship: a 2DD + 6BA + 2EST hybrid with high-grade Knowles/Sonion drivers, a gorgeous marbled faceplate, and—crucially—a vastly improved shell over MK2. Comfort moves from a 2-hour limit to all-session wear, and the stock package (solid cable with swappable terminations, foam and silicone tips) is well thought out. Tip choice meaningfully shapes performance; options like SednaEarfit Short or Comply foam push it toward its best.
Tuning follows a balanced, studio-leaning tonality with extra sub-bass warmth, delivering both clinical insight and genuine fun. Micro-detail is standout, bass is clean, textured, and physical (from Nirvana’s “Lithium” to modern hip-hop drops), and male vocals are among the most convincing heard on an IEM in this tier. Stage is wider and a bit taller than MK2, with excellent imaging, layering, and separation, keeping drums, bass guitar, and synth lines neatly organized without blunting impact.
For competitive gaming, the MK3 brings a tight soundstage, strong depth perception, and clear audio cue emphasis, offering precise 360° placement and adequate verticality. Versus Prestige Limited, it trades some sterile clinical edge for a more engaging, atmospheric presentation that reads distance and urgency better; compared to Yanyin Moonlight Ultra, it’s the more coherent pick for both games and music. While great mid-fi options like Zens Top, Orchestra Lite, or Yanyin Canon 2 remain strong, Monarch MK3 feels like the elevated, “dreamy” flagship experience—a new top choice for music enjoyment that also dominates in game when properly tipped.

Tonally, 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.

Youtube Video Summary
NiceHCK 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.

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.
