Exceptional bass, ethereal treble, remarkable clarity, and outstanding detail. The upper mid-range might be a bit too much for some people. Reveals every detail in your music, both the good and the bad.Gizaudio Axel original ranking

Upper mids kill it for me, but it's a fun set. Jaytiss Youtube Channel
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.

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.

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.

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.
