The TANCHJIM x Effect Audio Force employs a dual dynamic driver configuration, pairing a 10mm titanium-coated bass driver with an 8.2mm beryllium-coated mid-high driver. This setup, managed through Tanchjim's HPFD-Seg crossover technology, aims for cohesive integration, delivering impactful low-end while maintaining clarity in vocals and treble. The notable open-back design incorporates a pressure-relief nozzle to minimize listening fatigue, though isolation remains surprisingly effective despite the acoustic vents.
Tonally, the Force leans toward a balanced signature with a mild bass emphasis, avoiding excessive warmth while retaining texture in kick drums and basslines. Treble extension is smooth and non-fatiguing, though some may find airiness slightly reserved compared to brighter tunings. The standout inclusion is the Type-C DSP cable, enabling deep customization via Tanchjim's app—including parametric EQ and Harman target presets—which significantly refines the stock tuning for personal preference.
Technically, the open-back architecture contributes to an expansive soundstage with precise imaging, excelling in complex tracks where instrument separation matters. While dynamics are competent, micro-detail retrieval doesn’t quite match elite hybrid or EST-equipped IEMs in its price tier. The co-engineered Effect Audio cable and ergonomic resin shells ensure long-wearing comfort, rounding out a package that prioritizes refinement over raw resolution.

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.

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.

Clean, techinical v-shape signature with great midrange upper treble too much Tim Tuned Youtube Channel
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.

Great all-rounder. Slighty airy with good sub-bass extenion. Balanced but still fun. A cleaner, airier, and less sharp & sparkly version of the Meta - vocals pop out more than Meta. Tip rec Sancai regular or Softears Ultra clears. Jays Audio Youtube Channel
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."

Great all-rounder with a bright, airy top end. Deep, textured sub-bass, clean and forward mids, airy treble, and great detail. Upper treble can be a bit much, and the bass tuck isn’t for everyone.Gizaudio Axel original ranking

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.

The Kiwi Ears Astral offers a Meta + mild V-Shaped signature with a pronounced sub-bass shelf and energetic treble extension, deviating from its marketed "reference" label. The 10mm bioceramic dynamic driver delivers deep, textured lows, though some may find the mid-bass slightly lean for warmth. Mids remain clean but recessed compared to the lows and highs, with vocals occasionally lacking body.
Technically, the Astral excels with sharp imaging and a spacious soundstage, leveraging its six balanced armatures for precise instrument separation. Treble is well-extended and airy without harshness, though its emphasis can overshadow the midrange at times. While dynamics improve at higher volumes, the tuning feels more analytical than engaging for some genres.
Build quality is robust with resin shells, but the accessories are underwhelming for the price—only three tip pairs and a basic case are included. The modular cable is a welcome upgrade, though its stiffness may annoy some users. Fit varies due to the straight nozzle angle, demanding tip experimentation for comfort.
