Kiwi Ears Astral VS Fiio FX17

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, 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.

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."

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 FiiO FX17 is a mind-bending flagship IEM priced at $1,500, packing an absolutely hilarious 13-driver configuration per side: one dynamic for bass, four balanced armatures for midrange control, and a staggering eight electrostatic drivers for the highs. The sheer number of electrostats isn't a gimmick; FiiO explicitly states they're necessary to achieve sufficient sound pressure and avoid being mere "decoration," throwing serious shade at competitors. The result is nothing short of wild. Forget typical soundstage descriptions – the music doesn't feel like it's coming from two points in your ears or even from speakers in a room. Instead, it creates an entirely internalized, coherent performance happening inside your head, like the band is set up within your skull. It’s a cognitive living experience prioritizing placement and realism over simple frequency response graphs.

This psychoacoustic magic translates into pure, infectious enjoyment. Tracks feel aggressively present yet controlled, with kick drums hitting the back of your eyewall and intricate details like tap dancing percussively located behind your eyes. The separation and realism are phenomenal, making everything from the Beastie Boys to complex techno feel immediate and utterly engaging. While physically large with a fingerprint-prone mirrored finish and using the less-favored MMCX connectors, the FX17 is surprisingly comfortable and not overly heavy. Criticisms like the connector type are dismissed as irrelevant noise compared to the sonic achievement. Plugged into anything from a high-end stack to the included USB-C dongle DAC, the FX17 delivers its unique, immersive magic consistently.

The unboxing experience screams flagship, absolutely justifying the price tag visually. It arrives in a luxurious British Racing Green case with magnetic closure, featuring gold-accented packaging, a wooden storage plaque (unit 240 shown), a cleaning cloth, MMCX tool, ear wax brush, magnetic cable clip, and a mind-boggling 22 pairs of various eartips. Add in a very nice cable with interchangeable terminations (3.5mm & 4.4mm included, 2.5mm adapter not included) and the aforementioned USB-C dongle, and the package feels comprehensive and premium. Ultimately, the FX17 stands out dramatically in the crowded $1,500 IEM field. It’s declared worth every penny of $2,000, delivering a unique, transformative listening experience that prioritizes how the sound is presented over traditional audiophile checkboxes. It earns full, emphatic marks as FiiO's best audio reproduction product to date.

The Fiio FX17 emerges as a worthy flagship and a significant improvement over its predecessor, the FA19. This tribrid IEM boasts a unique driver configuration of one dynamic driver, four balanced armatures, and a staggering eight electrostatic drivers, all housed within a solid, lightweight titanium shell. While its aesthetic is considered a bit plain, the build quality is excellent. The package is loaded with a massive assortment of accessories, including seven different styles of ear tips and a cable with a clever built-in DAC adapter for smartphones.

Sonically, the FX17 delivers a warm, powerful, and engaging sound signature. Its bass is a particular standout, described as meaty, well-textured, and highly engaging without bleeding into the mids. The overall tonality is natural yet contrasty, offering a dynamic and punchy listen. The treble provides excitement and definition, though it can be slightly aggressive or "crashy" for those with high sensitivity, making it far from a "safe" tuning.

In direct comparisons, the FX17 is deemed superior in every way to the FA19, which was criticized for its bloated bass and splashy treble. It trades blows with competitors like the Dunu Glacier and ThieAudio Monarch Mk IV, offering a denser, more tactile experience than the Monarch's airy presentation and a more natural vocal tonality than the Glacier's more exaggerated V-shape. Ultimately, the FX17 is declared not only Fiio's best IEM to date but a compelling and engaging option in the high-end market.

The FiiO FX17 packs a hybrid 13-driver configuration featuring one dynamic driver, four balanced armatures, and eight EST drivers, priced around $1,500. Unboxing reveals a generous accessory suite: a premium leather case with magnetic closure, an MMCX removal tool, cleaning brush, cleaning cloth, and a magnetic cable holder. The highlight is the included modular cable with 3.5mm and 4.4mm terminations plus a specialized USB-C dongle enabling parametric EQ and firmware updates. Buyers also receive a staggering 22 pairs of ear tips – including SpinFits, liquid silicone, foam, bass-enhancing, vocal-focused, balanced, and double-flanged options – neatly organized across two cases. The cable itself earns praise for being soft, tangle-free, well-behaved, and featuring a functional chin slider.

Built from chunky titanium shells, the FX17 feels premium but substantial. While weight distribution prevents ear fatigue for some, its large size may cause fit issues for those with smaller ears, making a demo advisable. The nozzle diameter is 6.1mm. Sonically, the FX17 delivers a powerful, mid-bass focused slam described as punchy and meaty, though sub-bass rumble takes a backseat. The mid-range is warm, lush, and slightly relaxed, offering surprising clarity and excellent detail retrieval without shoutiness. Treble stands out as smooth, highly detailed, and non-fatiguing, providing ample air and shimmer without sibilance. Technical performance is strong, with great detail and separation, but the true star is the exceptionally wide, immersive, and realistic soundstage, particularly noticeable in the upper mids and treble.

Compared to the FiiO FA19, the FX17 offers a significant upgrade in bass physicality, smoother treble refinement, and superior soundstage. It also surpasses the Unique Melody MEST MKIII CF in detail, separation, stage width, and bass weight/texture. Against the pricier Elysian Apostle, the FX17 is warmer and more relaxed; the Apostle boasts tighter bass, clearer vocals, and sparklier treble, while the FX17 counters with a wider stage. This IEM is strongly recommended for mid-bass lovers seeking physical slam, listeners desiring warm, lush, non-fatiguing mids with clarity, treble enthusiasts wanting detail without harshness, and soundstage aficionados. It's not ideal for those with small ears due to shell size, listeners prioritizing deep sub-bass rumble over mid-bass impact, or anyone seeking a neutral or bright tuning. The FX17 earns a four-star rating for its standout qualities.
