HYPE 4 comes across as the sweet spot of the series: less bass than the HYPE 10, but tighter control with a midrange that feels more natural and unmasked. Listeners called it smoother and more versatile, with punch that doesn’t bleed into the mids and more apparent detail than the HYPE 2 and 10. Several blind testers either preferred it outright or put it neck-and-neck with higher-priced sets, estimating it around “$500” based on sound, while the actual tag sits near $400.
Against the rest, the HYPE 10 drew comments like “boomy,” “less cohesive,” and occasionally underwhelming, while the HYPE 2 read as Harman’s “cooler brother” with fuller male vocals but lower technical ceiling. The Monarch MK3 still edges the field on overall cleanliness, “air,” and refinement, and some would pay the extra $100 to jump there. But viewed through price-performance, the takeaway stayed consistent: HYPE 4 is the most worth it pick for most people, delivering a balanced, engaging presentation without the bloat or brightness trade-offs seen elsewhere in the lineup.

Kiwi Ears Astral reviewed by Jays Audio
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 Hype 4 arrives with surprisingly premium trimmings: a compact, comfortable shell (though some ears may need tip rolling for a secure seal), a supple cable akin to the latest Oracle 2/Monarch MKIII leads with a durable 3.5 mm plug, and a classy case lifted straight from pricier models. Overall presentation feels 2–3× its price, with tidy accessories and a cable that’s pleasant in hand even if it won’t lay perfectly flat.
Sonically it’s impactful and engaging: bass is lush and deep without smearing, mids keep vocals forward yet smooth for podcasts, and treble has air and detail without piercing. The tuning graph shows excellent channel matching and hugs a preferred target—3 kHz rise with a 5–6 kHz dip—which explains the easygoing clarity. Minor nitpicks surface: some cymbal shimmer can feel a touch “off,” and a few drum hits could carry more thump/realism; otherwise it’s a cohesive, “just sounds right” presentation that can deliver goosebump moments when the beat drops.
Against peers, Hype 4 comes off as a safer buy and more exciting listen than the Hisenior Mega5 EST (cheaper, better cable/case, and far less dull). It edges the Binary Chopin on overall quality—though Chopin stays a killer budget pick—and proves more fun and library-friendly than the detail-leaning Performer 8. Versus Monarch MKII it’s livelier with better sub-bass and treble reach; compared with Monarch MKIII, it avoids the fatiguing 4–6 kHz energy. The verdict: a mid-fi standout with near top-tier tuning, top-shelf packaging, and a value that challenges pricier options—highly recommended despite not being the absolute cheapest route to great sound.

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.

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.

Thieaudio Hype 4 delivers the redemption arc this series needed: a $399 hybrid that channels the beloved Clairvoyance vibe at a lower price. The 2DD+4BA setup hits with a chest-filling low end—powerful yet clean—while treble comes through with airy, flute-and-violin sheen, free of splash. Imaging feels gapless and pinpoint; handclaps and spatial cues lock into place with convincing realism. Despite “studio monitor” marketing, the tuning is smooth and musical rather than dry or clinical, inviting long sessions and even some dancing. Tip rolling (from silicone to foam-injected silicone) nudges seal and focus but doesn’t derail the signature, signaling a universally forgiving character.
At 17 Ω, the Hype 4 is easy to drive and plays nicely with everything from sterile DAC/amps to warmer class-A and even tubes—differences show as subtle nuance, not hit-or-miss synergy. Build is handsome in black/blue/white shells (the white “dragon-meat” look gets a wink), with a comfy deep-recessed 2-pin fit and decent included tips/foams. The miss: a non-modular 3.5 mm cable at this price, plus the usual accessory minimalism. Sonically, though, this feels like the $600-tier polish of the old Clairvoyance—cohesive, punchy, and silky across the band—making Hype 4 an easy recommendation. Final verdict: a confident 9/10 on sound, dinged mainly for the cable, and a clear “this is what Thieaudio should sound like” moment.

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.

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.

Thieaudio HYPE 4 hits far above its price with a lively, bass-driven tuning that stays clean and controlled. The low end delivers physicality without muddying the mids or presence region, evoking a “mini Monarch MK3” vibe for music playback. Resolution and micro-detail—fingers on strings, vocal intimacy—come through impressively, though note that pairing (e.g., a Topping DX9) can influence bass texture and perceived air.
In competitive titles, HYPE 4 reduces ambient haze so audio cues cut through like they’re “piercing a fog,” elevating depth perception and imaging. It takes the edge in Apex Legends, The Finals, and Counter-Strike 2, where some effects can sound metallic on other sets; here, separation remains intact even amid explosions and ultimates. Despite the energetic low end, separation stays steady and never overwhelms complex scenes.
Versus the Yanyin Canon 2, HYPE 4 is the more fun and slightly more resolving listen; Canon 2 can be preferable on tight, bass-heavy maps in Valorant and Fortnite, with Rainbow Six Siege essentially a toss-up. Comfort is close, with a slight fit edge to HYPE 4 over longer sessions. Overall gaming grade sits around a B+ (≈88 ±2) on the “wallhack certified” list—an excellent hybrid that bridges music enjoyment and competitive clarity at its price.

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.

The Thieaudio Hype 4 brings a hybrid setup of 2DD + 4BA at around $400, wrapped in a distinctive all-white shell with tidy faceplate patterning and a slightly tinted cable. Shell size is medium and the ergonomics echo other modern Thieaudio designs: easy insertion, stable fit, and genuine all-day comfort. Build quality and finish feel a notch more refined than usual for the brand, making the whole package look and wear better than expected at this price.
Tonality targets a neutral with bass boost profile, with emphasis kept largely to the sub-bass so things don’t turn warm or boomy. Versus Hype 2, there’s a touch more mid-bass and, more importantly, a firmer bass attack—swapping the softer, pillowy edges for punch and control. Treble stays smooth and well-controlled without sibilance. The star, though, is the imaging and head-stage: unusually wide and clean at this price, giving precise placement and clear separation that pops immediately on first listen.
Not everything is perfect—midrange micro-contrast can feel a bit “glassy,” so ultra-fine vocal texture and analog grit aren’t its specialty. In lateral comparisons, Yanyin Canon 2 plays warmer and fuller with slightly better textural nuance, while Hype 4 sounds cleaner, airier, and more expansive for live and electronic material. With meaningful improvements over Hype 2 (especially in bass behavior) and standout staging, Hype 4 earns a confident 4/5 as a polished, engaging all-rounder.

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.

The bass quality is great. Bass texture is phenomenal. Sounds like a sub in a large room. Other than that, the set has decent tech, soundstage, and overall tuning. Very good build quality. For bassheads.Cons
Bass can bleed slightly into mids. Air frequencies can be extremely distracting, so tip rolling is a must, especially due to the strange and extremely large fit. Pinna gain at 3khz can be too forward for some users. Imaging + separation ≈ 200$ set worth.Kiwi Ears Astral User Reviews
