Youtube Video Summary
Priced around $1,350, the Dunu Glacier is a premium nine-driver tribrid IEM featuring one dynamic driver, four balanced armatures, and four electrostatic drivers. The build quality is exceptional with a beautiful mirrored polished steel shell, though it's noted as a bit large, heavy, and a fingerprint magnet. Comfort is generally good, and it includes a high-quality, pliable cable with interchangeable connectors and a secure chin slider. Packaging is also highlighted as exceedingly well done, typical of Dunu's recent standards.
Sonically, the Glacier delivers a very bassy, extremely fun, and highly engaging V-shaped signature. The strong bass is balanced by prominent upper mids, offering good detail resolution and micro-details. However, a noticeable energy peak around 3kHz can make some tracks feel overly energetic, intimate, or even slightly shouty, limiting its versatility for mellower listening sessions. Comparisons place it near sets like the LETSHUOER Tera (less bass, cleaner) and ThieAudio Monarch MK I (less bass, more even upper mids), while noting it surpasses the Dunu Brain Dance (DK-31) in detail and bombast, though the Brain Dance offers significant value at half the price.
Ultimately, the Dunu Glacier stands out as a fantastic and unique IEM with satisfying bass weight, good imaging, and excellent micro-details. Its fun, bombastic character and high-quality build make it a compelling choice, but the specific upper-mid energy requires careful consideration. It earns a recommendation for those seeking an ultra-engaging Harman-style listen with top-tier driver tech, though demoing is advised due to its distinct tonal quirks.

Youtube Video Summary
The Dunu Glacier stands as the brand's latest flagship tribrid IEM, priced around $1,350. Its standout feature is its adherence to the Harman target curve, a rarity at this level, executed with notable success. The Glacier boasts exceptional build quality, featuring polished 904L stainless steel shells that feel substantial and genuinely premium, justifying its price tag aesthetically. It comes loaded with accessories, including a plethora of ear tips (like the Candy and new clear Dunu Lunnies) and a large carry case, though the case design is noted as slightly awkward. The included cable is thick, well-made, and features Dunu's signature swappable terminations (3.5mm and 4.4mm included), though its ear hooks are somewhat loose and the chin cinch doesn't hold perfectly.
Sonically, the Glacier delivers a contrasty, V-shaped signature true to Harman but avoids the thinness sometimes associated with that target, thanks to extra bass emphasis. The bass is a major highlight – big, impactful, deep, well-textured, and satisfyingly clean with zero bleed into the mids. The treble is forward yet remarkably smooth, avoiding sharpness or sibilance. While technically proficient with good imaging and a strong sense of depth (especially from the bass), it leans slightly more towards contrast than nuanced micro-detail, particularly in the mid-range. Compared to rivals like the 64 Audio U4s (more mid-focused, warmer, laid-back) and the Dunu Mirai (brighter, most mid-focused, wider stage but less satisfying bass and slightly digital/scratchier treble), the Glacier excels in bass impact and separation, smoothness, and depth perception, while the others might appeal more for pure mid-range focus.
Overall, the Dunu Glacier is a highly refined IEM with no glaring weaknesses. Its excellent build, satisfying Harman-tuned sound (especially the standout bass and smooth treble), and competitive technicalities make it a compelling option in the flagship tier. While its weight and aggressive shell molding might cause minor comfort issues when lying down, and the ear hooks could be tighter, it earns a very solid four-star rating for delivering a premium experience that largely justifies its cost and successfully champions the Harman target.

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.

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.

The Dunu Glacier delivers a technically impressive listening experience with its nine-driver tribrid setup (1DD+4BA+4EST). The stainless steel shells feel substantial yet remain comfortable for extended sessions despite their weight. Sonically, it presents a Harman-inspired tuning enhanced by significant sub-bass rumble and a notably wide soundstage, creating an expansive presentation.
Bass response is a standout, offering deep, textured rumble and strong physical impact thanks to the biocellulose dynamic driver, while the four EST drivers provide highly detailed treble without harshness. However, the upper mids can occasionally feel intense or forward on certain tracks, and the midrange sometimes exhibits a slight hollowness, making it less forgiving of poor recordings. While the soundstage width is exceptional under $2000, depth and layering don’t quite reach the absolute top tier.
At $1349, the Glacier justifies its price with a premium unboxing experience, including a versatile modular cable, multiple high-quality eartip options (Dunu S&S, Candy, SpinFit), and a distinctive design. It’s a strong choice for those seeking a dynamic, detailed signature with thunderous bass and a vast stage, though its revealing nature and shell size may not suit all listeners or genres.

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.

The Dunu Glacier delivers an extraordinary premium experience right from the unboxing, featuring a lavish presentation, a massive high-quality fabric cable with interchangeable terminations, and hand-polished stainless steel earpieces that feel substantial and expensive. Despite the controversial MMCX connectors, the cable and fit are praised, complemented by a ton of accessories including multiple ear tip types, a leather case, and even a brush. This is Dunu’s flagship effort at $1300, and the physical presentation screams luxury.
Sonically, the Glacier is a revelation with a massive, immersive soundstage that places instruments at a distance, creating a surround-like experience rather than an in-your-head assault. The tuning is remarkably relaxed and natural, prioritizing smoothness and spatial depth over aggression. Tracks with atmospheric elements or live recordings become breathtaking, revealing layers of echo and venue acoustics that feel expansive and holographic. This isn’t hyper-detailed or clinical; it’s chill, luxurious, and emotionally resonant, making even familiar music feel newly captivating.
Compared to competitors like the Thieaudio Prestige Limited or Monarch MkIII, the Glacier carves its own niche with its unparalleled sense of space and effortless presentation. It doesn’t compete on technical aggression but instead offers a transportive, almost spiritual listening experience. If you crave an endgame IEM that emphasizes grandeur, natural tonality, and pure musical immersion over analytical prowess, the Glacier is a jaw-dropping contender. Just be prepared for its unique, room-filling signature—it’s less an in-ear monitor and more a portal.

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.
