TOTL imaging chops/layering. Tons of micro-details. Great bass texture. Wide and 3D staging. Can be aggressive, and get fatiguing when cranked up/long-listening sessions.
Youtube Video Summary

UM MEST MKII delivers a distinctly sub-bass-oriented low end with excellent speed, separation, and texture. Mid-bass is punchy but avoids bloat, keeping the presentation clean and avoiding bleed. The unconventional decision to keep the 1–5 kHz region flatter and push energy into 5–15 kHz pays off: vocals stay open, natural, and clear—reminiscent of Variations but with a cleaner, leaner midrange and a more refined overall balance.

The stage is impressively wide and expansive—on the level of sets like Z1R and U12t—yet with notably better vocals. Treble is well-extended, slightly aggressive in a good way, and highly resolving, rendering micro-details with ease without tipping into artificial sharpness. As a result, technical ability—clarity, separation, and imaging—is top tier, making dense tracks feel effortless while still bringing energy and excitement to hip-hop and retaining emotional nuance for ballads.

In sum, MEST MKII stands out as a true all-rounder “endgame” that justifies its $1,500 tag more convincingly than most. Notable comparisons place it a step above sets like Meteor, Mahina, and Variations for the mix of enjoyment and technicalities, though value hunters may note EJ07M achieves roughly “90%” of the experience at a fraction of the price. The only caveat: treble can become too lively at very loud volumes (80 dB+), but at normal listening levels, MEST MKII remains a compelling benchmark for its category.

Smooth listen, non-fatiguing, balanced and leans towards neutral, scales good, full, natural, but lacks dynamics/transients and vocal extension. Reminds me of the OG SA6 with a little more treble and low-end, but less mids, and even more pulled back vocals... Similar to the Meta tunings, reminds me of a more neutral Astral/Crescent/Horizon - Good, but a bit overhyped and priced a bit high for a 1DD+3BA, tech is slightly behind the Astrals and should be under $300 imo.
Youtube Video Summary

YU9 Que presents a balanced, almost neutral tuning with a tasteful touch of mid-bass for warmth and punch. Treble is clean and controlled—more clarity than “sizzle”—so detail comes through without harshness, while mids keep vocals natural rather than forward or thin. Technical performance sits in the “solid for the price” camp: separation and imaging are tidy, but not the kind of hyper-etched sparkle that chases wow factor.

In practice, it shines with slower pop, R&B, acoustic and vocal-centric tracks where its coherence and smoothness pay off; those seeking big sub-bass drama or ultra-aerated treble fireworks may find it a touch polite. Versus brighter, more contrasty sets, the Que trades spectacle for musicality and long-session comfort, making value hinge on whether a refined, low-fatigue signature is preferred over maximum excitement at the price point.

Very engaging. I usually prefer something more balanced and neutral, but this IEM has some special sauce. Very well-tuned from bass to treble - with a little bit of spice on top. Great tonality and amazing techs. Imaging is quite phenomenal, separation is great. Very detailed. If you have 700 to spend on IEMs, buy these on the used market and never look back. Warning - treble can be slightly hot. Also, timbre might sound just a tad artificial.

Balanced, contrasty, highly resolving. Very good transients. Tight bass, clean mids, very well extended treble. The only glaring flaw is the one-dimensional imaging - there is very little layering, unfortunately which can make instruments and vocals sound like they're all standing in a straight line in front of you. Nonetheless, an excellent IEM!

Exceptional tuning and treble refinement; sets the benchmark at $400.
Youtube Video Summary

Yu9’s Que lands as a “safer Annihilator”: a warmer, scaled-back take that pushes ample sub-bass while keeping the rest tastefully controlled. The low end feels liquidy and bouncy, underpinning an aggressive 1–3 kHz rise with a gentle 3–5 kHz taper, so vocals sit upfront and crisp yet remain remarkably smooth thanks to the extra low-end warmth. Treble is slightly scooped around 5–6 kHz and then climbs in small, well-placed peaks out to ~15–18 kHz, yielding excellent extension that feels on par with sets like Moondrop Variations in this range.

What makes it pop is the value proposition: at $400, the overall resolution, tonal balance, and staging read far pricier—more like the $700–800 bracket. With its engaging sub-bass lift, lucid mids, and airy yet controlled top end, Que comes off as a polished, crowd-friendly tuning that still excites detail chasers. If momentum holds, this looks like the next big thing around the $400 mark.

Youtube Video Summary

The YU9 Que sports a premium, durable resin shell in pure black with a metallic-feeling faceplate and a comfortable design featuring an anti-tragus catch. While the build itself feels handsome and unique, the included cable is criticized as wimpy and unpleasant, with a strong suggestion to upgrade it. Accessories are deemed solid, including a nice selection of tips and a particularly praised case with a soft, luxurious interior.

Sonically, the YU9 Que earns immense praise for its exceptional tuning, described as clean, resolute, and non-fatiguing. It delivers strong, textured bass that avoids being overwhelming, coupled with extremely well-done upper mids. While not class-leading in technicalities like micro-detail or instrument separation, its tonal balance is considered sophisticated and reminiscent of far more expensive sets like the Annihilator, even surpassing the Monarch MKII in tuning preference. It's highlighted as a fantastic all-rounder with a smooth, agreeable signature suitable for long listening sessions.

Despite its modest single dynamic driver + 3BA configuration and $409 price point, the YU9 Que is declared a very special and unique IEM, worthy of the hype it received. The review concludes it's a price leader and a highly competent package from a small brand, offering outstanding value and a beautiful, well-executed design that makes it an easy recommendation for those seeking a smooth, non-fatiguing sound.

One of the most refined, fun, engaging, and technically capable IEMs for its price. Treble is very refined and surprisingly not fatiguing. Well-textured bass with strong physicality. Clear, vocals. Refined, non-fatiguing treble with plenty of extension. Class-leading detail and separation. Treble may be too much for some.
Youtube Video Summary

Build & accessories: a hybrid 1DD + 3BA set priced around $399 with a spacious zipper case, multiple silicone tips, pouches, cleaning cloth, and shirt clip. The faceplate’s wavy, stone-like texture looks premium, and the shells use a 2-pin connector. The downside is the stock cable: it’s springy, only in 4.4 mm, and feels below the tier. Fit is serviceable but not ideal—the shell isn’t the most ergonomic, the nozzle lacks a lip, and seating a deeper fit can take a moment; once set, stability is good and tips stayed secure in use.

Sound: this isn’t a “new-meta” curve; it’s a unique, lively tuning. Bass is punchy, dynamic, and highly textured—more physical in practice than the graph suggests, with excellent impact and kick-drum authority. An early rise after 1 kHz pushes vocals front and center for an intimate, engaging presentation without tipping into shout. Treble is refined, sparkly, and well-extended: it is a bright set but avoids harshness, peakiness, sibilance, and fatigue, delivering crisp cymbals and defined transients even for rock and metal at any volume. Technicalities are class-leading under $500 with standout detail retrieval and separation; the one wish is a larger soundstage.

Comparisons & verdict: the Elysian Apostle still wins on bass texture/impact, treble refinement, and overall resolution, but the Yu9 Que offers a convincing “Apostle flavor” at a lower price. Versus Elysian Pilgrim, the Que is fuller and bassier, while Pilgrim’s treble is tamer; versus Volume S, the Que is cleaner, brighter, more detailed as the Volume S trends warmer with more neutral treble; against Dusk DSP, Dusk sounds more natural/balanced but the Que feels more fun and technical. Recommended for those who crave clarity, sparkle, and engagement without fatigue; less ideal if treble-sensitive or preferring a warm, relaxed tonality, and worth demoing for comfort. A top contender and serious gatekeeper around $400—final rating: 4.5/5 with a strong recommendation.

YU9 Audio QUE is a $300 hybrid (1DD + 3BA) with a name rooted in Chinese culture—“阙” (QUE, palace), paired with a fish bone logo from “鱼” (YU, fish). Shells are aluminum with a sandblasted, wavy faceplate finish.

Tuning is clean, neutral, and slightly V-shaped: bass is tight, bouncy, and textured; mids sit slightly forward thanks to extra 700 Hz–2 kHz gain, giving vocals a bigger image; treble leans bright with a 4–5 kHz push for clarity, rolling off naturally rather than chasing EST-style air. Sibilance can appear (on “th” or “tsu”), but not harsh.

Stage favors width over depth—impressively wide at the price, with neat, well-ordered placement and strong separation. Resolution is crisp, background clean, every note clearly etched.

Youtube Video Summary

Yu9 Que arrives with a surprisingly premium unboxing: a crush-resistant carrying case with plush padding, an IEM pouch, microfiber cloth, cable clip, and two ear-tip sets (standard silicone and more premium liquid silicone). A quirky 3D-printed nameplate with serial number and a faceplate etched in a topographic-map motif give it character. The shell is on the larger, wider side—comfortable for many, but small ears should test fit first. The stock cable is just okay (some memory, no chin slider), though it’s offered in 3.5 mm or 4.4 mm terminations.

Tonally, this is a neutral-reference set with a tasteful bass lift—clean impact without throwing off balance. Sub-bass has satisfying thump and texture, though bass-heads coming from sets like Kiwi Ears Punch may find it polite. The mids sit even and accurate—no “vocal magic,” yet clearly above average. Treble stretches well into the air with a touch of brightness that adds crispness and a slightly clinical edge, staying shy of fatiguing. Technical chops are the draw: a decently wide soundstage (roughly 3–4/5 by comparison), standout 3D imaging, and strong resolution/separation make it excellent for gaming—worthy of a two-controller nod—though ultimate detail still trails pricier kilobuck options.

Versus peers: Moondrop Dusk (DSP) is warmer with bass that hits a bit harder, while Yu9 Que is the more neutral, reference-leaning take. Elysian Pilgrim offers smoother treble, but Yu9 Que counters with better bass grip, stage, and imaging. AFUL Performer 7 tilts mild V; choose it for extra mid-bass and forward treble, otherwise Yu9 Que wins on technicality. Mega 5 EST chases the meta target yet stumbles in bass/treble; NiceHCK Rockies refines that approach and might be the more exciting alternative if spending slightly more. Bottom line: the hype is justified—a superb all-rounder around $400 with only the cable begging for an upgrade. It’s a clear pick for neutral/reference fans, though those seeking more “fun” might look elsewhere; call it a pragmatic, two-star recommendation amid a crowded market and likely pre-order waits.

Web Search 8.3 Reviewer Score
S- Tuning
A+ Tech

The YU9 Que is a hybrid IEM using 1 dynamic driver + 3 balanced armatures, positioned in the mid-upper price tier with an MSRP around $399. Retail listings confirm the configuration (10 mm LF DD with three Knowles BA units) and current pricing in USD and MYR, placing it among competitors that emphasize tonal refinement over sheer technical fireworks.

Community impressions describe a balanced/neutral tonality with a tasteful bass lift, smooth upper-mids that avoid glare, and treble that leans non-sibilant. Subjective reports on Head-Fi and Reddit consistently frame the Que as an all-rounder that favors coherence and long-term listenability over maximum micro-detail.

Technically, listeners note solid imaging and macrodynamics with competent detail retrieval, though not class-leading for the price. The manufacturer has also published frequency-response plots (IEC711 and BK5128 rigs), which aligns with the community’s take that the Que targets a broadly neutral/balanced signature rather than an aggressive V-shape. Overall value is credible at its MSRP if you prioritize tonal balance and comfort over ultra-analytical presentation.
