Reviewer Score
The JUZEAR x Z Reviews Defiant is a 1DD/3BA hybrid IEM that boasts a solid build quality with a comfortable, vented shell and a metallic nozzle that holds ear tips well. It comes with a modular cable that can be switched to a 4.4mm connector and a set of decent accessories, including a case that is described as nothing extraordinary but is overall quite nice. The physical package is reliable and functional, providing a good foundation for the experience.
Where the Defiant truly shines is in its fantastic tonality and tuning. It delivers a bassy and engaging sound with good treble that never gets too shouty or harsh, making it an excellent choice for long listening or gaming sessions. The graph shows it follows a very competent target curve quite closely, resulting in an all-around solid and highly enjoyable sound signature that is both relaxing and engaging without major faults.
Priced at around $100, the Defiant is deemed a highly competitive offering in its segment. It goes head-to-head with other popular sets like the Letshuoer S08 Planar and the 7Hz Aeroso, trading blows depending on whether one prefers a hybrid or planar driver presentation. While it may not have the absolute best treble extension and isn't going to "light the world on fire," it represents a great value with its excellent tuning, making it an easy set to recommend for anyone seeking a fun, well-tuned, and comfortable IEM.

The JUZEAR x Z Reviews Defiant is a shockingly good hybrid IEM that absolutely demolishes low expectations. For under $100, this collaboration delivers a surprisingly well-tuned sound that stands out in a crowded budget field. The package is compelling, featuring a nice carry case, a plethora of ear tip options for dialing in the fit, and a cable with swappable terminations that is functionally excellent, even if its red-and-blue "candy cane" aesthetic is a matter of taste.
Sonically, the Defiant boasts a tasteful V-shaped signature with a significant, well-executed bass boost that is tight, impactful, and devoid of muddiness. The treble is surprisingly clean and extended, coming across brighter than measurements might suggest, giving the entire presentation an exciting, engaging, and contrasty character. This tuning results in surprisingly good imaging and instrument separation for the price. While the fit is comfortable for most, the semi-custom shells are a bit "slabby" and rely on the ear tips for security rather than locking into the ear's folds.
When compared to a close competitor like the Aful Explorer, the Defiant's more exciting, contrasty, and imaging-focused sound is a clear differentiator. The Explorer offers a warmer, more relaxed, and natural alternative with better mid-range body. Ultimately, the Defiant earns a solid four out of five stars, representing a fantastic and highly competitive option for anyone seeking a bassy, engaging, and well-built hybrid under $100.

Balanced, detailed, and versatile. It sets the bar for its price point. Punchy, textured bass, natural and forward vocals, balanced sound, with great detail and imaging. A great all-rounder.Gizaudio Axel original ranking

The JUZEAR x Z Reviews Defiant is an absolute standout in the $100 IEM category, delivering a performance that feels like it belongs in a much higher price bracket. It comes packed with fantastic accessories, including a hard-shell carrying case and an awesome modular cable with both 3.5mm and 4.4mm connectors, which is a rare find at this price. The build is compact and ergonomic, offering superb comfort for long listening sessions and even sleeping, with above-average noise isolation.
Where the Defiant truly shines is in its sound, described as a fantastically balanced all-rounder that is engaging and never boring. The bass is a major highlight, offering a deep, rumbling sub-bass and a hard-hitting mid-bass with excellent texture and detail that avoids muddiness. The mid-range is natural and forward, giving vocals superb clarity and pop without ever becoming shouty. The treble is crisp and detailed with a clean sparkle, providing plenty of micro-detail without a hint of harshness or sibilance, making it great for treble-sensitive listeners.
Technically, the Defiant punches way above its price, boasting impressive resolution, a wide and deep soundstage, and phenomenal imaging and layering that can compete with many sets under $200. While it may not suit those seeking a reference, warm, or extremely bass-heavy signature, it earns a solid 4.5-star rating and stands as a new benchmark, offering a staggering level of performance that defies logic for a hundred dollars.

Pleasant, neutral warm tuning with good treble extension that wholly belies its price point. Precogvision Youtube Channel

The JUZEAR x Z Reviews Defiant executes on an old meta, IE 2020 tuning with a bass boost, and it does it exceptionally well. The bass is present but not overwhelming, and the treble is smooth and never piercing. The true star of the show is the forward, full, and thick mid-range that provides a fantastic vocal experience without becoming shouty. This is all backed by excellent timbre that makes vocals and instruments sound largely natural, resulting in a colored yet highly engaging sound signature.
While the overall tuning is praised, the bass is noted as the one area for a slight nitpick. It has good power and control but lacks a completely natural decay, a minor shortfall attributed to the sheer forwardness of the mid-range stealing the spotlight. Technically, the Defiant is a standout, landing ahead of competitors like the Aria 2 and being one of the most detailed IEMs around $100, on par with the TruthEar Hexa.
In comparisons, the Defiant is positioned as a fun, exciting, and colored alternative to the neutral Hexa and the warm, relaxing Aria 2. It also differs from the Dunu Titan S by offering a fuller vocal presentation and greater versatility thanks to its actual bass shelf. For its $99 price, it receives a very high B grade for sound and a wholehearted recommendation, especially for those new to the hobby or anyone who loves a forward, engaging vocal presentation.

Another all-rounder with good balance. Doesn't do anything right or wrong, but has qc issues with channel imbalance (and also my case ziper broke within a few weeks), it's ok but there are better value out there. Jays Audio Youtube Channel

It's a fun tuning that I think people will like. Jaytiss Youtube Channel
Build & accessories land in a solid spot for the price: comfortable shells with secure nozzles, clear L/R marks, and a supple modular cable that swaps between 4.4mm and 3.5mm (no USB-C in-box). The hard case is nicely made and pocketable, and the whole package feels durable if not premium. Nothing glaring in QC—just a clean, practical presentation.
Sonically, this is a bold V-shape—huge sub-bass punch with elevated upper mids to keep things lively. The bass can turn boomy/pillowy on some tracks, and a scoop around 300–800 Hz can leave female vocals a touch recessed; treble is clean and controlled, a little dark up top with limited sparkle. Technicalities are decent rather than class-leading—separation and air trail sets like Punch Audio Martillo or Crescent, while tuning kinships show up against DUNU Glacier and even Grand Maestro-style balances. Compared to value darlings (e.g., Truth Ear Pure, Jazzer Defiant), ITO feels more audiophile-flavored fun than an all-rounder.
In DUNU’s lineup it reads as a unique basshead option: very engaging slam, thick note weight, and non-fatiguing treble, but only average mids/technicalities. Think hip-hop/EDM-friendly impact over neutral precision. Verdict: around 3–3.5 stars—competitive at $200 for those chasing thump and excitement; listeners wanting neutrality, vocal presence, or extra air may prefer other picks or a “tactful V” with less bass and less upper-mid bite.

Dunu’s collab with Japanese creator Kaji Kaji lands as the ITO, tuned nothing like the stereotype of “treble ’til you die.” The presentation leans smooth, warm, and open, with a notably wide soundstage that flatters jazz and intimate acoustic sets—think late-night, bourbon-and-smoky-room mood without the glare. It’s built for relaxed musicality rather than forensic detail extraction.
Low end carries a thick, satisfying sub-bass that stays tasteful—present when the track calls for it, not a constant spotlight. The ITO plays “fun first”: big space, plush tone, and enough detail to keep things engaging, landing beside a “T Pro”-type set but with the clinical edges dialed back to emphasize bass and stage. In short, a “perfect fun IEM” vibe that prefers groove and atmosphere over microscope listening.
Ergonomically the shells are a bit thick, but build and accessories impress: a quality Dunu cable with interchangeable plugs, a case, and a spread of tips (including Dunu SS). The hybrid 2DD+2BA setup (ultra-low DD + low/mid DD, mid BA, ultra-high BA) at around 37 Ω runs well from modest sources and scales nicely; pricing circles the $200 mark, making it an easy recommendation for listeners who want warm, expansive, and genuinely musical tuning without chasing every last micro-detail.

DUNU x KOTO ITO is a $199.99 hybrid IEM built with Japanese reviewer Kaji Kaji (“Koto”). It uses a 2DD+2BA array (10 mm bio-diaphragm DD + 8 mm LCP DD, plus two treble BAs), comes with DUNU’s Q-Lock quick-swap plugs, and lists 105 dB sensitivity at 37 Ω with shells at ~6.5 g each.
Tonally, ITO aims for a U-shaped, bass-tilted balance: sub/mid-bass punch is elevated, mids sit slightly back but avoid haze, and treble is smooth with workable extension rather than bite. Early community impressions frame it as energetic and a touch V-leaning versus DUNU’s more neutral sets, which tracks with the collab’s “full-bodied” intent.
Technicalities are competent for the class: dynamics and imaging keep up with busy mixes, while soundstage and microdetail are closer to average among sub-$200 hybrids; driveability is friendly given 105 dB/37 Ω. As a package—tuning, accessories, and fit—it offers good value for listeners wanting engaging bass without sharp treble, though those chasing expansive stage or strict neutrality may prefer other options.
