Kiwi Ears Astral reviewed by Jaytiss
The Kiwi Ears Astral offers a solid build quality with comfortable shells that fit well, featuring a practical nozzle design that holds ear tips securely. The included cable is notably high-quality, featuring a functional chin slider, a sleek bluish-purplish-gray hue, and connectors that are exceptionally easy to swap. While the case is utilitarian and similar to other Kiwi Ears offerings, the overall package is practical and well-appointed.
Sonically, the Astral stands out as a special and highly competitive set at its $299 price point. It delivers a beautifully tuned, balanced tonality that hugs the target curve closely, offering a satisfying amount of bass, well-executed upper mids, and a generally pleasing, non-fatiguing sound. While it may occasionally lean slightly shouty or risk sounding dull on certain tracks compared to more aggressively tuned alternatives, it excels as a refined all-rounder. Its technical performance – including spaciousness, detail retrieval, and rich bass texturing – is impressive for the price, though micro-details and ultimate pristine clarity aren't class-leading.
The Astral trades blows with top competitors like the Performer 7 (slightly darker/richer) and the Volume S (better dynamics but less sub-bass), often coming out ahead for its cohesive balance. It significantly improves upon predecessors like the Kiwi Ears Quartet or Singolo, offering better upper-mid presence and technicalities. Ultimately, it represents a fantastic option for those seeking a well-tuned, balanced IEM, delivering a highly enjoyable and versatile listening experience with minimal faults. For its price, it's exceptionally hard to beat, earning strong marks across the board.

Thieaudio Valhalla lands as a 19-BA flagship around $2,000 that doubles down on build and ergonomics. The titanium shell is chunky but beautifully machined, skin-friendly, and the nozzle grips tips securely; faceplates are swappable for a premium if the stock look isn’t it. Accessories are basic—tips, foams, brush, the usual case—and the stock cable is comfy with a working chin slider, but the modular 3.5/4.4 plugs don’t lock and can pop off too easily. The slightly recessed 2-pin is fine, yet the ear-side barrel leaves a small gap that doesn’t sit flush; a simple aftermarket cable fixes the vibe. Taken as an object, this is world-class industrial design with a couple cable quirks.
On the ear, Valhalla hits a clean, incisive neutrality with just enough flavor. Sub-bass is surprisingly firm for BA, mid-bass stays tidy, and the mids are pristine—no glaze, no haze. There’s a tasteful dip through ~3–6 kHz that keeps the upper-mids from shouting, while a touch of 8 kHz sparkle adds air; treble extends smoothly without turning edgy. It’s a highly technical, high-resolution listen that can read “almost boring” if a colored signature is the goal—but for detail, separation, and coherence, it delivers. Unit variation appears minor (another sample showed a bit more 4–6 k energy), yet the core tuning stays intact.
Versus housemates: Origin swings bassier and “fun”; Valhalla feels cleaner, clearer, more resolute. Hype 2/4 don’t match the air and microdetail; Hype 10 gets closer up top but raises value questions. Oracle MK3 has more 4–5 k zing and lighter sub-bass; Fatfreq Grand Maestro hits similarly rich lows but brings fit hassles and module faff. Against the Elysian Annihilator, pick Annihilator for extra sub-bass and spectacle; pick Valhalla for comfort, longevity, and easy cable-swapping. Not perfect—the stock cable system is flimsy and the “air” isn’t the most crystalline—but this is a top-tier contender with a refined, broadly pleasing tuning and a shell that feels built to outlast the hype.

The Kiwi Ears Astral, priced at $299, combines one dynamic driver and six balanced armatures in an exceptionally ergonomic and lightweight 3D printed resin chassis. Comfort is phenomenal, allowing for extended listening sessions exceeding eight hours without discomfort. Available in striking blue or gold faceplates, the Astral impresses immediately with its build and feel.
Tonally, the Astral offers a fantastic, well-balanced V-shaped tuning. It features punchy, airy, and well-separated bass with notable sub-bass rumble that avoids muddying the exceptionally clear and resolving mids. The treble provides very good extension, feeling airy, technical, clean, and fast, contributing to an overall presentation that sounds more expensive than its price tag. While generally excellent, providing too much power can make the upper region slightly spicy with certain intense audio cues. The technical performance – imaging, separation, layering, and micro-detail retrieval – is phenomenal across various music genres.
For competitive gaming, the Astral truly shines, demonstrating holographic imaging and precise depth perception. In Valorant, it excels at differentiating multiple footsteps and gunfire sources with urgency and precise horizontal and vertical placement. It handles chaotic moments in CS2, Apex Legends, and Call of Duty exceptionally well, maintaining clear separation during intense firefights, grenade explosions, and air strikes without becoming fatiguing or overwhelming. Tip selection is crucial for optimal performance, with recommendations leaning towards options like the Azla EarFit Light. Despite including a decent interchangeable cable and silicone tips, third-party tips are suggested. Ultimately, the Kiwi Ears Astral is a fantastic all-rounder, delivering top-tier performance for both music and competitive gaming at its mid-range price point.

Thieaudio Valhalla lands as a lavish, 19-BA-per-side flagship tuned warm-natural with a palpable sub-bass emphasis, quick attack/decay, and standout separation and layering. Vocals read both natural and technical—male and female alike—without bass bleed, while the treble carries enough air to keep micro-detail clean. Comfort and build impress, making it an easy all-day daily driver and a legitimate endgame pick for music that also crosses over to gaming.
In shooters, Valhalla excels at depth perception, verticality, and parsing simultaneous cues. For Call of Duty it’s an outright S-tier: footsteps, fly-ins, and distant strikes are easy to place with zero guesswork. In Apex Legends it sits around A to A-—gunfire is beautifully controlled, but super-light slides/taps can be a touch subdued. In Valorant it’s highly competitive with top open-backs, while in CS2 the tuning keeps gunfire less shouty and footstep reads strong, making it a great IEM choice overall. Net result on the “wallhack certification” scale: A to A- across multiple titles—an expensive IEM that earns its keep if both music enjoyment and competitive clarity are on the checklist.

The Kiwi Ears Astral presents a well-rounded, balanced sound signature characterized by a boost in sub-bass and treble air, sharing some DNA with the Meta but offering significant improvements. It delivers a punchier, harder-slamming low end with better texture, making drums feel livelier and more impactful compared to the Meta. The mid-range and vocals are also more forward and less relaxed, creating a fuller sound versus the Meta's brighter, leaner presentation that highlights treble sparkle. While not vocal-centric like the Arcanis, the Astral excels as a true all-rounder.
Technically, the Astral edges out the Meta, offering better bass texture, improved vocal clarity, and slightly more micro-details in the mid-range and treble. Its value is strong at roughly $50 more than the Meta. However, the boosted air region can make the treble sound slightly wispy or fatiguing at higher volumes on very energetic tracks laden with symbols or air, making it best suited for mid-volume listening (around 65 dB). Genre-wise, it shines as an all-rounder at this volume, providing clean, extended, natural vocals, a thumpy low end with good rumble, and extended, airy treble. Compared to the Odyssey, the Astral is cleaner, more detailed, smoother, and airier, working better for mid-centric genres like indie, acoustic, and classical, though the Odyssey scales better at higher volumes and feels fuller for pop, metal, R&B, and hip-hop.
Positioned as a strong contender for the best all-rounder under $300, the Astral is seen as a more complete version of sets like the Pilgrim and Dusk, offering better sub-bass extension, texture, and rumble with less shouty vocals and sizzly treble. It significantly outperforms the Performer 5+2 technically for only $50 more and is a tier above the Kiwi Ears KE4 in clarity and technicalities. While specific alternatives like the EPZ P50, Tanchjim Origin, or Cadenza 4 are better for vocal focus, and sets like the Estrella or Deuce excel for bass, the Astral stands out for its balanced, engaging, and technically proficient performance across most genres at mid-volume. Expecting potential sales around $260, it's heralded as the new all-rounder benchmark under $300, ideal for listeners who want a single versatile IEM where "everything just sounds great."

Thieaudio Valhalla lands as an “endgame” all-rounder with standout resolution, micro-detail, and imaging. Layering and separation are locked in, with vocals that aren’t scooped—mids stay present and natural. Sub-bass hits rumblier than the U12t and the treble avoids that sudden, sharp peak, making the overall presentation smoother yet still airy. Versus the Cadenza 12, Valhalla is less treble-heavy, a touch bassier, and not as bright-leaning; the Cadenza 12 may edge it on micro-detail by only a few percentage points, so it’s a straight tuning preference: go Cadenza 12 for leaner/brighter sparkle, go Valhalla for the better-balanced bassy all-rounder.
On value, this isn’t twice the performance of a Monarch Mk II/Mk III—think ~10% better with clear diminishing returns. For the “chase the very best” crowd, it’s absolutely worth a listen; for most, Monarchs/LTD/Crimson are already more than enough for a so-called endgame. Final call: Top Tier for tuning and sound refinement—not a value pick, but a legit endgame-grade set.

Kiwi Ears Astral reviewed by Z-Reviews
Priced at $300, the Kiwi Ears Astral stands as the brand's most expensive IEM, featuring a 10mm dynamic driver and six balanced armatures. The build is notably large and deep, with a design described as "pepper" yellow or more appealing "blue crystal" – though the included accessories are minimal, offering just one set of tips, replacement filters, and an interchangeable connector (3.5mm or 4.4mm). The gunmetal gray four-wire cable earns praise for its quality and flexibility, but the deep connector adds significant length, potentially hindering portability. Simply put, at this price with so little included, the sound must deliver.
And deliver it does. The Astral produces an exceptionally wide and holographic soundstage, achieving impressive "instrument realization" – creating an almost unsettling sense of space where sounds can emerge from above, below, behind, or beside the listener. The tuning is decidedly chill and smooth, prioritizing effortless listening over aggressive detail. The dynamic driver handles frequencies up to 300Hz, providing satisfying warmth and weight to the bass, while the six BAs contribute significantly to the expansive staging and air. This isn't a sound easily found in sub-$100 IEMs; it offers a unique, relaxed presentation reminiscent of far more expensive models, like certain $1,500 Final Audio IEMs known for holographic imaging.
The Kiwi Ears Astral emerges as a strong contender for favorite IEM of the year. While it lacks accessories and its large, somewhat plain design might not win beauty contests, its unique sonic character justifies the $300 price tag. It carves out a niche as a "big wide smooth" option, perfect for extended, fatigue-free listening sessions where the goal is pure enjoyment and astonishment rather than analytical treble scrutiny. It competes favorably with $500+ IEMs known for soundstage, offering a glorious, spacious, and utterly engaging listening experience that makes revisiting tracks a joy. For those seeking a high-end, chill sound with exceptional staging and bass foundation, the Astral is a magnum opus worth serious consideration.

Unboxing & build land solidly for the price: a genuinely pocketable zip case, three pairs of narrow-bore tips, spare nozzle filters, and a modular 3.5/4.4 cable with a secure push-pull lock. The four-wire cable is soft, low-memory, and only lightly microphonic at the slider. Resin shells are a bit chunky with a short metal nozzle (6.0 mm at the widest) and average isolation, but the seal is stable and the comfort is excellent for long sessions—just not ideal for sleeping due to the slight protrusion.
Tonally, Astral aims for a Meta-style tuning with extra upper-treble air: clean, detailed, and engaging. The bass is sub-bass focused—tight, textured, never boomy—with punchy but restrained mid-bass; quality over quantity, delivering standout rumble and definition (A+ bass quality). Mids are the highlight: clean, forward vocals with natural timbre and strong separation. Lower treble adds clarity without sibilance, while the elevated upper air brings sparkle and space; it can read a touch crisp for sensitive listeners, especially on bright masters or at high volume.
Technicalities impress: excellent imaging, open width, and resolution that surfaces micro-details and locks centers convincingly. Versus Kiwi Ears K4, Astral trades K4’s warmer, fuller mid-bass for tighter bass, clearer vocals, and more air; versus Xenns Tea Pro, Astral offers better bass texture and cleaner, more forward vocals; against ZiiGaat Odyssey, Astral is the more resolving and airy set, while Odyssey feels fuller and more relaxed with tamer upper treble. Recommended for those wanting a detailed all-rounder, Meta-leaning balance, forward mids, and textured sub-bass; not for upper-treble-sensitive listeners or those craving heavy mid-bass and warmth. Final verdict: 4/5, competitive and confidently recommended at its price.

The Kiwi Ears Astral arrives in a package typical for the brand, featuring a resin shell and a metal nozzle. While the design isn't groundbreaking, the build feels sturdy. The included cable is a pleasant surprise, better than expected and features interchangeable terminations. A major highlight is the inclusion of Sancai ear tips, considered valuable accessories at this price point. However, the fit presents some challenges: the shells are notably bulky and chunky, pushing comfort limits for larger ears, and the angled cable hooks can cause sealing issues, though switching to larger tips helps significantly.
Sonically, the Astral delivers a solid bass and mid-range balance. Yet, the standout issue is the treble presentation. It's perceived as quite forward and adds a noticeable digital edginess to the timbre, making details sound overly prominent and somewhat unnatural. While technical performance seems improved over models like the original Wan'er, this treble character overshadows the positives. Initial impressions suggest it falls short of previous Kiwi Ears releases like the Quartet or Singolo, with even the Lush potentially being preferred. The Sancai tips and overall package offer good value, but the tuning needs refinement.

The Kiwi Ears Astral is a mid-priced hybrid with 1DD+6BA and an MSRP around $299, positioning it in the competitive $250–$350 class. Official specs list a 10 mm bioceramic dynamic driver, 23 Ω impedance, and 105 dB sensitivity, indicating easy drivability from portable sources. Reviewers generally characterize its tuning as U-shaped with a neutral lean rather than a warm tilt.
Sonically, the Astral features a sub-bass shelf with an intentionally attenuated mid-bass, keeping male vocals clean but reducing punch; upper mids are clear and articulate, and treble shows good extension without harshness. Multiple reviews note clarity and articulation taking priority over warmth, with a presentation that suits vocal-centric tracks and preserves top-end air. A second perspective frames it as a lively, well-judged U-shape with tangible bass weight and controlled treble energy.
Technical performance is a strength for the class: reviewers highlight soundstage width/height, stable imaging, and solid resolution that avoids clinical edges. Trade-offs include modest mid-bass impact and only moderate micro-detail versus pricier sets, which tempers overall value at this price but still makes the Astral competitive for listeners prioritizing clarity and staging.

Thieaudio Valhalla reviewed by Super* Review
2025-08-19Thieaudio’s Valhalla is a $2,000, all–balanced armature flagship packing 19 balanced armatures in new-for-the-brand metal shells. The look leans understated—gunmetal/pewter with a hint of rosiness—and the build feels solid, though the stock cable is thick and the swappable plugs rely on friction with no positive lock, which can pull loose. Fit is still large, but notably better than recent Monarch generations: once seated it’s stable and secure enough for long sessions, even if it won’t disappear in-ear.
Tonally, Valhalla targets a clean neutral with a meaty, sub-bass–focused boost, slightly warmer through the mids and less peaky up top than Monarch Mk IV. Despite being all-BA, the bass feels more dynamic and satisfying than the Monarch’s, and the big story is technical performance: imaging, separation, stage definition, and overall resolution are genuinely standout—“flagship-grade” in a way many kilobuck sets aren’t. Downsides are the sheer size and that cumbersome cable, but as a listen it’s special and compelling. Verdict: four stars out of five, and an easy pick over Monarch Mk IV on sonics if the fit works.

ThieAudio Valhalla comes in hot as a true flagship challenger: a titanium shell housing 19 drivers—14 “Sonion” and five “Knowles"—and a price planted in the ~$2K bracket. This tier isn’t like GPUs where benchmarks decide winners; earphones here are closer to watches—craft, taste, and execution. On that score, Valhalla feels legit: premium build, branded internals, and tuning aimed squarely at high-end competition that regularly asks two to three times more.
The low end lands with plenty of energy and control—808 drops for Ghetto Boys/Public Enemy/Wu-Tang/Kendrick/Tupac/Outkast hit clean, while four- and five-string bass guitar lines carry real texture and decay. Iconic kick work like “When the Levee Breaks” thumps with satisfying weight without smearing. Midrange is dialed: no bloated mid-bass warming up female vocals, no shouty upper mids pushing voices unnaturally forward—great for a vocal-centric library and classic cuts (think “Sultans of Swing”). Up top, harmonics extend with air and clarity without the zingy fatigue—decays aren’t chopped off, so cymbals and overtones feel complete rather than muted.
On ranking, this reads as a top-five contender with this library, easily competing with sets in the $4–6K lane on balance, quality, and tuning. The only real ding is the presentation box, which doesn’t scream “luxury” the way the sound and build do. Verdict: squarely between “would buy” and “going to hype it.” Given ThieAudio’s run of legit releases (Monarch line, Oracle MKIII, etc.), Valhalla fits the pattern—no weak link in the chain, just a serious flagship play at a price that undercuts many rivals.

Extremely clean separation and technical performance. Treble is very clean at price point. Mids are clear and transparent, and are simply good with little to no coloration. Forward vocal region, but does so in a way that should be great for all.Cons
Midbass could be raised slightly, and sub bass can be too forward at times. Treble clarity only slightly behind much more expensive sets. Raised 7-9khz region, but not peaky.A technically adept IEM with a balanced, engaging U-shaped signature that excels in bass texture, vocal clarity, and spatial presentation—offering exceptional value despite sparse accessories.
Pros
Powerful, textured sub-bass with deep rumble; natural vocals with excellent clarity; airy, non-fatiguing treble with strong extension; and outstanding imaging/soundstage for the price.Cons
Limited eartip selection affects fit optimization; bulky shells may cause discomfort during extended use; mids occasionally lack warmth and can feel slightly recessed.Thieaudio Valhalla User Reviews
