Youtube Video Summary
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.

Youtube Video Summary
Naming drama aside (P5+2? just call it Performer 7), this Aful packs a quirky driver party: 2DD for low end, 4 BA split across mids/treble, plus a tiny micro-planar for the highest sparkle, all marshaled by Aful’s neat miniature crossover. The shells are lightweight, comfy and prettier than they need to be; the cable feels “don’t bother swapping” nice, with 3.5 or 4.4 options. The box is loaded with silicone tips but no foam—a miss, because the right seal changes everything. Price target sits around $250, which sets expectations high but not ridiculous.
Stock silicone yields a surgical, respectful tuning with bass that skews neutral and controlled. Swap to well-sealing foam or hybrids and feed a juicy source (warm Class A or tubes) and the set wakes up—stage snaps into a cohesive scene right in front, imaging gets laser-etched, and that micro-planar adds a pinch-of-salt treble spice without turning harsh. It’s an up-close presentation—sometimes almost claustrophobically detailed—in the best way: think “men with trumpets in the head,” precise placement, and excellent extension up top. Not as rowdy as the Explorers; more like a surgeon in a Hawaiian shirt—technical, but with a wink.
Practical upside: the clarity and positioning make this great for gaming and even viable for mixing/mastering checks; just don’t crank it into pain territory. Bass stays tight and responsive, treble sails high, and coherence holds. Tip and source matter a lot: with foam + warm power, it sings; with plain silicone, it’s merely polite. Final tally: a confident 8.5/10—doing a lot right at its price, dinged half a point for making everyone do math on the name.

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.

Aful Performer 5+2 lands as a hybrid of the beloved Performer 5 and the punchier Explorer. The unboxing is the familiar P5 affair—same case, same style of tips—nothing flashy, but solid. The shell mirrors the P5 in size with a comfy little stabilizing wing that locks in well. No metal nozzle or front filter here, yet tip retention is secure and hassle-free. The flat 2-pin socket is straightforward, and the stock cable feels thick and supple with a reliable chin slider and handy red/blue channel markers. Overall: understated build, great ergonomics, daily-driver ready.
Sonically, this one aims neutral with a very distinct top end—clean, dynamic, incisive. Think switching from black-and-white to color; cymbals and overtones pop with a slightly crunchy/pristine edge that energizes detail without turning harsh on good recordings. Bass isn’t about sheer quantity; it’s about slam and dynamics—quick on the draw, well-controlled, and satisfying when called upon. Vocals sit a notch forward, microdetail is strong, and the overall presentation is coherent, clear, and technical with convincing stage, resolution, and imaging. Not a treble-shy or bass-bombed tuning—more a refined all-rounder for those who want clarity and bite.
Versus the original P5, the 5+2 fixes the missing “air” and soft edges, trading them for crisper transients and better extension. Compared with Explorer (a value champ), the 5+2 brings superior upper-treble reach, detail, and vocal focus. Against Performer 8 and Cantor, it feels more visceral—the P8 is smoother and more relaxed, while Cantor pulls finer microdetail but with less bass slam. Sets like Dino Quattro or J’s Estrella bring bigger fun or treble theatrics, yet the 5+2’s balance and everyday versatility win more often. Net take: a neutral-leaning, highly technical upgrade that stands tall in its bracket—easy to recommend to anyone chasing clarity, speed, and controlled impact over pure warmth or excess bass.

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
Aful’s Performer 5+2 upgrades the original hybrid with 2DD + 4BA + 1 micro-planar tweeter and lands around $240–$250. The unboxing is practical: three sets of silicone tips, a pocketable puck case, and a soft, nicely draping cable (available in 4.4 or 3.5), though the braid can look a bit loose and the pre-formed hooks run large. The resin shells shift between blue and green under different light; fit is medium-large, very stable, and comfortable once the right tips are found. Note the narrow nozzle without a retaining lip and partially exposed bores/filters—tip grip is key and a little care prevents ear-gunk ingress.
Tonally this leans mild V-shaped: a clean midrange with a confident bass boost, a touch of lower-treble presence for bite, and well-extended air up top. The result is more incisive and punchy than the original P5, with clearer on/off transients that aid separation and layering. Trade-offs show as a hint of gritty/plasticky treble texture on cymbals and brushes—not harsh, but less natural than ideal—while the bass stays tight and exciting.
Against Aful’s Explorer, this sounds brighter, more spacious, and more technical; Explorer plays warmer/denser with smoother treble but less openness. Versus the pricier Thieaudio Oracle MK3, tuning is broadly similar: Oracle is smoother and deeper with a softer attack, while the Performer 5+2 brings more snap and engagement for less money. As a modern mid-tier hybrid, it absolutely still has a place—energetic, spacious, and well-executed—earning a solid four stars.

Youtube Video Summary
Performer 7 lands with a neutral-balanced, laid-back tuning and good treble reach. The presentation is clean and generally safe, though there’s a touch of sizzly “planar-ish” timbre up top. Technicals are solid for ~$200—slightly behind sets like Quintet and Super Mix 4, about on par with Nova. Bass from the dual 6 mm DDs is tight, controlled, and free of bleed, but lacks the slam and rumble of competitors using larger drivers; mids are well separated with decent layering.
The weak spot is vocal extension: a push around 1.5 kHz tries to bring them forward, but a dip through 3–6 kHz keeps them from opening up. Tamer upper-mids help avoid fatigue for rock/metal, yet the modest low-end impact leaves drums and basslines feeling uneventful. It’s a mid-volume set that doesn’t scale well—turning it up accentuates the 1.5 kHz emphasis and treble sizzle. Treble isn’t peaky, just a bit glassy at times; for K-pop the smoother mids can work if less extended vocals are acceptable.
As a value play, there are stronger options: Nova, Chopan, and Super Mix 4 offer better bang-for-buck; for a similar clean/neutral target, Tanchjim Origin sounds more natural with better bass texture and vocal reach, and DynaQuattro adds sub-bass and fuller vocals—none with the planar-ish timbre. Even AFUL’s own P5 is cheaper and more fun, while the Explorer undercuts the price and scales impressively. In today’s crowded market, P7 is a competent all-rounder but not distinctive enough to stand out.

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 AFUL Performer 5+2 (also listed as “Performer 7”) uses a 2DD+4BA+1 micro planar driver array and AFUL’s LC-network crossover plus a 3D-printed acoustic tube system, aiming for clean band splits without smearing. The shell also integrates a high-damping air-pressure balance system, a design AFUL has used across its line. Official listings put MSRP around $229 and outline the same core tech features.
Tonally it trends neutral with a sub-bass lift: bass has solid depth and texture, mids stay relatively linear, and the presence/treble region adds energy without veering into sharpness on most chains. Multiple reviews characterize it as warm-neutral with bass boost or slightly V-shaped depending on perspective, which matches listening notes about a lively but controlled upper end. Sensitivity and load are portable-friendly (≈109 dB, 15 Ω), so it reaches performance without demanding amplification.
Technicalities are competitive for the class: imaging is tidy with good instrument separation, micro-detail retrieval is above average, and soundstage is moderate (more width than depth). Build and comfort are typical resin-shell fare; some users note occasional lower-treble bite depending on tips and recordings, so treble-sensitive listeners may wish to pair accordingly. Overall value is strong at its price, especially if a clean, bass-supported neutral curve is the priority.

Youtube Video Summary
The AFUL Performer 5+2 (Performer 7 / P7) takes the P5 recipe and adds a second 6 mm dynamic for the lows and a micro-planar for the highs, nudging MSRP to $240. Unboxing mirrors the P5: nine pairs of tips and a decent case, but the accessories feel bare-bones at this price—no foam tips and a non-modular cable, even though the included 8-wire is supple and well-behaved. Build is classic AFUL: 3D-printed resin, blended nozzle (no mesh or lip—watch tip retention), single rear vent, and striking blue-green mosaic shells inspired by Suzhou gardens—cool-wall approved with four compliments to one “meh.” Fit is semi-custom and a touch chunkier than P5; comfortable for most, a conditional pass for small ears. Note a sporadic batch quirk: some units have over-tight 2-pin sockets; exchanges fixed it for affected buyers.
Tuning sits in warm-leaning neutral territory. The dual dynamics deliver punchy, textured bass that rumbles without bloating; guitars and drums carry convincing weight. Mids are the star—rich, full-bodied, vocal-forward without shout, with clean separation and natural tone. Treble from the micro-planar is smooth yet energetic: cymbals and vocal harmonics sparkle, special effects have bite and body, and only treble-sensitives may find hot mixes a bit lively. Technicalities impress for the money—detail retrieval and nuance feel a class up—while stage and imaging are solid rather than showy.
Against peers: the Tangzu x HBB budget pick mirrors the overall tonality but P7 offers higher resolution and more treble finesse; the planar “Heyday” alternative is brighter/faster with leaner bass; versus Performer 5, P7 brings tighter low-end, smoother treble, and better extremes detail; the Fresh-collab competitor pushes vocals further forward with bigger stage but leaner lower mids. Verdict: a versatile all-rounder that suits broad libraries and even content creation thanks to its balanced tonality and detail. Not for bassheads, trebleheads, or strict Harman-lean seekers, and the accessory pack/cable quirk holds it back from a slam-dunk. For roughly $240, though, it’s a brilliant, resolving upgrade in the AFUL line.
