Better low-end texture and overall more engaging than MK2, but lacks the mid-range/vocal magic, so depending on your preference either is great. Still TOTL tech like MK2. Great all-rounder.
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.

Bassy dynamic all-rounder with great low-end texture that slams hard with good note-weight/body. Slight Hype 4 upgrade. Treble is smooth, and vocals are well-tuned. Overall unboxing/accesories are great... just no ESTs at its price, I'd wait for sale.
Youtube Video Summary

Softears RSV MK2 shifts from the OG’s vocal-centric tilt into a bass-forward all-rounder. The sub-bass and mid-bass hit with real slam and weight, giving drums and bass guitars a satisfying, dynamic punch. Upper mids (3–6 kHz) are tamed to avoid shout, while a gentle 1–2 kHz rise keeps vocals open and natural—slightly less pushed than the original but still clear. Treble is smooth with decent air; not super sparkly and there’s no EST “sauce,” but it stays clean and non-fatiguing.

As a package, MK2’s standout is the low-end texture—thunderous yet controlled—making it one of the more engaging bassy sets under four figures. Technical performance is solid for the tier, though some rivals at lower prices bring more raw detail and EST extension. Build and accessories get a tasteful, modern refresh. For best balance, the stock tips work well; bass-boosting or treble-opening tips can shift it toward a more V-shape at the expense of overall smoothness.

On genre fit, MK2 shines with hip-hop, pop, EDM, and R&B, where its punch and warmth bring rhythms to life; for orchestral or leaner acoustic picks, the bass can edge forward depending on the mix. It scales to mid–high volumes nicely (around the 70–80 dB zone) without turning sharp. Compared with the OG RSV—now likely affected by a silent retune in recent units—the MK2 is the safer buy: less shout, more authority down low, and a broader all-rounder appeal. Recommended, especially if found below full MSRP, for listeners craving tasteful bass with natural mids and relaxed, smooth treble.

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.

Softears RSV MK II reviewed by Super* Review

Super* Review 8* * score rescaled + normalized
A 5-BA successor that lands at $700, claims “re-engineered” BA bass, and feels like a welcome throwback to when high-end Chi-Fi wasn’t four figures. Build and fit are excellent with a rock-solid seal; the thick cable behaves well but annoyingly ships 4.4-only with a 3.5 mm pigtail. Tonally it’s essentially neutral up top with a big low-end shelf—treble is clean and non-fatiguing, imaging competent, and the bass is unusually physical for all-BA, though it can be inconsistent (and a bit tubby on bass-heavy mixes) versus a good DD. Net: a supremely competent, do-everything all-rounder that trades “wow” factor for balance—I prefer it over Dunu SA6 Mk II, see Symphonym Meteor and Moondrop S8 as taste-based alternatives, and I land at a solid 4/5.
Youtube Video Summary

Softears RSV MK II brings back the all-BA ethos at $700 with five armatures and a promise of “re-engineered BA bass.” Build and accessories feel premium (sleek shells, plush case), while the cable choice is quirky—4.4 mm only with a 3.5 mm pigtail. Fit is outstandingly secure and custom-like but on the larger side with a longer nozzle, so comfort depends on ear size. Softears’ Ultra Clear tips work well; the new metal-ring variant adds little beyond novelty.

On the graph, bass looks like gigabass, yet in ear it settles into a warm, weighty foundation without steamrolling the mids. The midrange follows a “new-meta neutral” tilt—fuller than Harman with forward upper-mids—while treble lands clean and sparkly without fatigue. Imaging is tidy rather than cavernous; separation and delineation are convincing, with the top end executed better than the bottom. BA bass here is among the more physical and satisfying of its kind, though tactility can be track-dependent and turn a bit tubby on very bass-heavy mixes.

Against peers, Symphonium Meteor sounds warmer and more “special” but less all-round; DUNU SA6 MK2 is more colored with janglier treble and the least convincing bass; 7th Acoustics Supernova trades warmth for vivid, bright-tilted imaging; Softears Studio 4 is lighter on bass and airier; and the old Moondrop S8 stays the lively, vocal-centric counterpoint. Net take: a supremely competent, character-light all-rounder that favors bass weight over panoramic staging. Verdict: 4/5 stars—a welcome throwback done right, and notably cheaper than the original RSV launch price.

The RSV MK2 still follows Softears’ signature approach: an all-BA design, specifically, five-BA configuration. The “V” stands for both its five-driver layout and its bold carbon-fiber faceplate design.

On the graph, it diverges from JM-1 or Harman, choosing its own path. Sub-200 Hz is elevated, giving the bass notable weight and warmth, but also risking congestion. A dip between 200–600 Hz thins mids and robs some body from vocals and instruments, though it does clean up edges. Then comes a surprising 14 kHz BA-driven peak, adding air, shimmer, and openness—rare for an all-BA set!

In practice, bass hits with real presence for BA, punchy and convincing though not as deep as DD. Mids lean slightly thin, a bit lack of density, making instruments less woody. Treble is airy and crisp thanks to that 14k lift, but may edge bright for sensitive listeners. Stage favors forward bass and a sense of openness, though not massive in depth.

Verdict: It’s bassy, airy, and a touch thin in the middle—a distinct tuning philosophy that stands apart from the crowd.

The Softears RSV MK II refines the original RSV with an all-5BA design and a 4-way crossover, targeting a stable “reference sound” while improving driver control and airflow management. It’s easy to drive at 122 dB/Vrms, 7 Ω, and the build mixes medical-grade resin with CNC-milled aluminum and forged carbon for a robust, low-resonance shell; MSRP is $699.

On paper, the tuning remains neutral with a bass lift: dual Knowles CI22955 woofers aim to give BA-bass more texture and weight, an improved ED driver anchors clean mids, and a SWFK unit handles upper treble for a smoother, less fatiguing top end. Softears’ LRC network and dual pressure-relief approach target consistent FR and reduced ear pressure, which should aid long listening sessions and imaging stability.

Subjectively, this positions the RSV MK II as a coherent, midrange-centric set with tight, controlled low-end rather than maximal slam, and a smooth treble that trades sparkle for fatigue-free listening. Soundstage is moderately wide with tidy imaging; technicalities are competitive for the class but won’t chase ultra-etched detail specialists. Given the tuning goals and efficient drive requirements, value will appeal most to listeners prioritizing tonal accuracy and midrange timbre over sheer sub-bass impact or treble air.
