Pros: 
• Forward, natural-sounding mids with great vocal clarity
• Deep subbass with satisfying physicality
• Sparkly, extended treble without fatigue
• Clean, fast transients and excellent imaging
• Clever modular cable design.

Cons:

The Kiwi Ears Astral is what happens when a brand says, “Let’s stop playing it safe and just have some fun.” And fun is exactly what you get. With its 7-driver hybrid setup—one dynamic driver and six balanced armatures—the Astral doesn’t tiptoe around polite tuning choices or try to blend in with the crowd. Instead, it charges in with a bold, energetic sound that’s designed to grab your attention from the very first note.

It shares some genetic material with the Septet, sure—but this isn’t just a sequel or a gentle upgrade. The Astral feels more like a reimagining, with the energy dial turned way up. Where the Septet leaned toward refinement and balance, the Astral is all about vivid vocals, deep, rumbling bass, and treble that sparkles with just enough restraint to stay comfortable. It has its own voice, its own flair, and it’s not afraid to show it.

Whats in the box? here is my quick unboxing video of the Kiwi Ears Astral.

Design & Build
Visually, the Astral keeps things classic. The faceplates come adorned in that familiar Kiwi Ears colorful glitter aesthetic—tasteful, not gaudy—with a silver logo etched (or embossed) in neatly. The shells are molded from resin in a CIEM-style shape, offering a snug, ergonomic fit that gives a tight seal and excellent noice isolation. There's a single vent at the top of the shell—clearly there to keep the DD breathing without messing up pressure balance.

One thing I absolutely love? The modular cable. It’s a braided, good-quality unit with a clever push-pull system for swapping terminations. No more dealing with those finicky screw-type connectors—just a clean, simple pop-on/pop-off mechanism to switch between 3.5mm and 4.4mm. It's practical, well-made, and frankly, more brands should be doing this.

Bass
The bass on the Kiwi Ears Astral comes out swinging. This isn’t your shy, tucked-away low end—it’s big, bold, and full of rumble. The subbass digs deep and delivers a satisfying, physical kind of presence that gives the whole presentation a strong foundation. It’s the kind of low-end that makes cinematic scores feel thunderous and EDM drops hit with gusto.

That said, it’s not the most disciplined bass out there. The subbass tends to bleed a little into the midbass, which slightly softens its impact and precision. The midbass, while vivid and clean enough in tone, lacks a bit of the punch and weight that would have given it more authority. It leans a touch loose and can feel a bit thin in spots—especially when the track demands tight, snappy hits.

But for what it aims to be, the bass gets the job done—it adds life, energy, and a bit of swagger to the sound. If you enjoy a more fun-leaning presentation and don’t mind a bit of extra rumble, Just don’t expect razor-sharp tightness or a super-clean slam—this is more “dance floor shake” than “monitor-grade thump.”.

Midrange
Now this… this is where Astral really finds its groove. The mids are clearly the heart and soul of this IEM—as if the entire tuning revolves around bringing vocals and instruments to life. There's a naturalness and clarity to the mids that you don't often find in hybrid IEMs with this kind of energetic tuning. Vocals, in particular, are a standout—they’re full-bodied, textured, and carry a wonderful sense of presence that puts them front and center without sounding overcooked.

Despite being BA-driven, the midrange has an organic quality to it. It doesn’t come across as artificial or overly smoothed out. Instead, it delivers just the right amount of warmth and weight to feel lifelike, yet remains clean, precise, and fast. Instruments like guitars, pianos, and strings have excellent timbral accuracy, and the transient response keeps everything sounding agile and articulate.

This is where Astral earns its musicality and its ability to keep vocals emotive, instruments vivid, and everything in between well separated and coherent. It’s not just a mid-forward tuning—it’s a well-executed one that gives the entire presentation a solid anchor.

Treble
The treble on the Kiwi Ears Astral walks a fine line between excitement and finesse—and it walks it well. It’s lively and energetic, bringing just the right amount of sparkle to give tracks a sense of air and dimension. Fast transients and crisp articulation mean microdetails come through effortlessly—hi-hats sizzle, cymbals shimmer, and string overtones glisten, all without ever tipping into harsh or fatiguing territory.

What really stands out is how controlled it all feels. There’s no erratic peakiness, no sharp sibilance, and certainly no fake, metallic shimmer that some BA-heavy IEMs can suffer from. Instead, the highs here feel clean, purposeful, and naturally extended, adding clarity and space to the mix without drawing too much attention to themselves.

It’s the kind of treble that invites long listening sessions. Engaging, yes—but never aggressive. It keeps the overall presentation feeling open and layered, lending a nice sense of air and separation between instruments, especially when paired with the Astral’s nimble imaging. It’s not the brightest treble out there, but it doesn't need to be it’s articulate, mature, and tastefully done.

Soundstage & Imaging
The soundstage on the Kiwi Ears Astral doesn’t go for exaggerated width or cinematic depth—it keeps things more grounded, but still convincingly spacious. It’s not the kind of stage that wraps around your head or stretches out into the horizon, but it never feels cramped or congested either. There’s just enough room for everything to breathe, and more importantly, enough clarity to make it count.

What really elevates the experience is the imaging. Thanks to the speed and separation of the BA drivers, the Astral is able to place instruments and vocals with remarkable accuracy. You can easily track where things are coming from—whether it’s the snap of a snare just off-center or the reverb trail of a guitar floating somewhere behind the vocals. Layering is handled with confidence, making even complex mixes feel orderly and controlled.

It may not deliver a “grand” or holographic presentation like its sibling the Septet, but it nails the essentials: precision, stability, and spatial awareness. The result is a soundstage that feels coherent and immersive without trying too hard to impress.

Pairing it with my r2r dongle.
Since the Astral can lean a little clinical or sharp with sterile sources, i find it best to pair it with gear that brings warmth, smoothness, or a bit of analog soul.

so i tried pairing it with something like the Heartfield R1 R2R dongle, and a bit of magic starts to happen. The subbass tightens up, vocals gain a gentle warmth with a more relaxed, rounded decay, and the treble? Still airy, but no longer sharp just easy and musical. The R1 smooths out the Astral’s edges and gives it a more laid-back, analog vibe.

Tips i tried with Astral.
• Wide-bore silicone (e.g., Divinus) – Opens up staging and smooths out treble a bit. Good for clarity.
• Included Stock silicone - Balance, smooth and comfortable, good seal and isolation.
• Foam tips – Tames brightness, improves comfort, and helps with isolation but personally i dont like the feel of the foam so i usually use the regular divinus velvets for most of my reviews.

Astral vs. Septet
While both IEMs come from the same Kiwi Ears bloodline and share a multidriver architecture, their execution and personalities couldn’t be more different.

1. Tuning Philosophy
• Astral: Fun, forward, and lively. Emphasis on subbass, energetic upper mids, and sparkly treble. It’s tuned to grab your attention and keep it.
• Septet: Smoother, more mature, and refined. The Septet leans into cleanliness and balance, with a slightly relaxed treble and a more linear midrange presentation.

Bass
• Astral: Big, bold, and a bit loose. Subbass is deeper and more visceral. It’s less controlled but more exciting—especially for genres like EDM, hip-hop, or cinematic scores.
• Septet: Tighter and more disciplined. Bass doesn’t slam as hard, but it’s faster and better defined. More suitable for acoustic, jazz, or classical.

Midrange
• Astral: Emphasized and front-and-center. Vocals have great presence and energy, especially in the upper midrange. There's a mild sense of warmth and excellent naturalness.
• Septet: More laid-back and neutral in its midrange delivery. Vocals sit further back in the mix and feel slightly thinner but more analytical and clean.

Treble
• Astral: Crisp, fast, and vivid—detailed but not harsh. Adds air and excitement without sibilance.
• Septet: More reserved and smooth. Still detailed, but lacks some of the sparkle and bite found in the Astral.
•
5. Technical Performance
• Astral: Great clarity, strong imaging, and excellent transient speed. Slightly more energetic than resolving.
• Septet: Slightly higher resolving ability, especially in high-volume listening or complex mixes. A touch more refined and coherent.
•
6. Overall Presentation
• Astral: Engaging and emotionally energetic. Perfect for vocal-driven tracks, pop, and modern genres.
• Septet: Relaxed and articulate. A thinking man’s IEM—better for long sessions and analytical listening and more like a planar over-ear headphones

Verdict: Choose Astral if you're after excitement, vocal energy, and an engaging listen. Go for the Septet if you prefer refinement, smoother tonality, and a more balance presentation. Personally, I’m a bit biased toward the Septet—it checks all the right boxes for me and has easily earned a spot as one of my personal favorites.

Final Thoughts – Bold, Balanced, and Fun
The Kiwi Ears Astral is a daring entry in the hybrid IEM space. It’s not going to please every listener, especially those who crave absolute bass control or ultra-warm tonality—but it isn’t trying to. Instead, it delivers a fun, mid-centric signature with deep bass impact, articulate treble, and technical chops to match. It’s bold without being brash, detailed without being dry, and fast without sounding rushed.

If you're into forward vocals, lively transients, and a sound that leans clean yet engaging—this might just be the hybrid you're looking for. Just pair it with the right source, and let the stars align. :)
