Reviews by Ianbanz

The Roseselsa Aurora Ultra is a perfect example of why you shouldn’t let appearances fool you. Despite their pint-sized footprint—seriously, these things are so tiny that I had to break out my large-size Divinus Velvet tips just to get a snug, secure fit—they punch way above their weight when it comes to sound.

The Divinus Velvet tips ended up working even better than the included SoundCocoon tips, giving me a perfect seal and letting the Aurora Ultra really show off what it’s capable of. And let me tell you: it’s a lot. These little guys deliver a soundstage and impact that’s way bigger than you’d expect from such a compact shell. cramming a full-bodied, immersive sound into something that’s almost comically small.

The moment you put them in and hit play, you’ll forget how tiny they are. You’re greeted with a big, bold sound that’s warm and textured, lively and dynamic, and polished in a way that feels surprisingly premium. It’s one of those rare IEMs that makes you do a double-take: “How is all this coming out of something so tiny?” It’s proof that a how clever design and good tuning can really make a product stand out, no matter its size.

Whats in the box? here is my quick unboxing video for the Aurora Ultra:








Build & Accessories:
For the price, the build quality of the Roseselsa Aurora Ultra is surprisingly good. The shells themselves feel solid and well-finished, with a snug fit that stays comfortable even through long listening sessions—once you dial in the right tips, of course (for me, those large Divinus Velvet tips did the trick!).







The accessories package is equally impressive. I’m especially fond of the case. It’s a hard-shell case with a faux leather-like surface that feels unexpectedly classy, and the magnetic snap closure has this satisfying little “click” that just screams quality. Admittedly, it’s a bit big for the Aurora Ultra themselves (these things are tiny, after all), but I’m not complaining—if anything, it’s become my go-to case for carrying other gear around too. Definitely a big step up from those flimsy soft pouches you get with a lot of IEMs (looking at you, Hidizs!).




And let’s not forget the included cable: it’s soft, tangle-resistant, and microphonics-free, making it a great pairing for these IEMs. Even better, they’ve thrown in a nifty little dongle—the RZ200m, this dongle actually holds its own. It’s well-made and delivers a clean, balanced sound that pairs beautifully with the Aurora Ultra’s tuning.



Included Dongle – RZ200m:
They even throw in a nifty dongle—the RZ200m, a 3.5mm to Type C converter with an ALC5686 decoder chip. It boasts a 124dB SNR, 32-bit/384kHz PCM playback, and a dynamic range of 113dB. While I’m usually a bit skeptical of bundled dongles, this one actually performs respectably, offering a clean and balanced sound that pairs well with the Aurora Ultra’s tuning.

Driver Configuration:
The Aurora Ultra sports a hybrid driver setup with a 10mm dynamic driver for that punchy low end and a 6mm planar magnetic driver for exceptional transient response and treble detail. The third-generation topological diaphragm and Daikoku voice coils work together to reproduce an ultra-wide sound range, from rumbling lows to shimmering highs.



Sound Performance:

Bass:
The bass on the Roseselsa Aurora Ultra is nothing short of impressive, especially for such a compact set. It’s bold and confident, with a weighty presence that anchors the entire sound. There’s a satisfying punch to the midbass that gives drums and bass guitars a solid thump, while the subbass reaches deep enough to deliver those satisfying rumbles in tracks that demand it. It’s not a basshead-level slam, but it’s got a healthy, engaging impact that adds a sense of richness and warmth to the presentation.

What I love is how this bass manages to stay clean and controlled—it never smothers the mids or bleeds into other frequencies. Instead, it add a layer wrapping around the music to give it warmth without muddying the details. It’s got enough texture to keep things interesting, revealing the variances in basslines and percussion. For me, it’s that sweet spot: punchy and full-bodied, but never overwhelming. It balances beautifully with the lively mids and that sparkly, airy treble, making the whole presentation feel well-rounded and cohesive.


Midrange:
The midrange. It’s quick on its feet, with fast transients that make instruments pop and shimmer with impressive clarity.

Vocals, while detailed and natural, do tend to sit just a step behind the instruments. It’s almost like they’re part of the ensemble rather than the lead performer—a slightly more laid-back approach. Honestly, I find it pretty charming. It works especially well for instrumental-focused tracks, jazz sessions, or classic rock anthems where the instruments take center stage. The mids here are vibrant and clear, and that touch of distance in the vocals means nothing ever feels too shouty or in-your-face.

Overall, the midrange has this wonderfully balanced vibe—enough energy and detail to draw you in, without ever feeling overdone. It’s a tuning that makes the Aurora Ultra feel both lively and easy to listen to, especially for long listening sessions.


Upper Mids & Treble:
They’re vivid and focused on technical clarity rather than sheer lushness, which means details jump out at you in a way that’s both crisp and engaging. Acoustic guitars, violins, and snare drums in particular sound wonderfully textured and snappy, with a satisfying bite that keeps you hooked.

There’s a slight forwardness to these upper mids, but it’s done tastefully—enough to add excitement and presence without tipping over into shoutiness. That clarity also gives vocals a nice lift, even if they’re set a step back in the overall mix.

The treble follows suit with a nicely extended, airy presentation that feels open and spacious. It adds a touch of sparkle and refinement, which keeps the whole sound signature feeling fresh and lively. Despite this liveliness, the treble never strays into harshness or becomes fatiguing—there’s a certain smoothness and finesse that ties everything together beautifully.

I especially love how this airy, well-extended treble works with the rest of the sound signature. It opens up the soundstage and adds a layer of shimmer to the Aurora Ultra’s already dynamic character. Its detailed, sparkly, and just downright enjoyable.


Technical Details:
Soundstage & Imaging:
For such a compact IEM, the soundstage is remarkably wide and open. There’s a good sense of depth as well, creating a three-dimensional feel that keeps things from sounding cramped or congested. Imaging is sharp and precise—you can easily pick out the position of instruments and vocals in the mix, which really adds to the immersive quality of the listening experience.

Separation & Layering:
Separation is another strong point. Each instrument has its own space, and complex tracks never feel cluttered. Whether it’s a dense orchestral piece or an intimate acoustic track, the Aurora Ultra keeps everything neatly layered and easy to follow. The fast transient response of the planar driver plays a big role here, helping to maintain clarity even when the music gets busy.



Final Thoughts:
For around $40, the Roseselsa Aurora Ultra is, without a doubt, one of the best value sets I’ve stumbled upon this year. It delivers a confident, well-balanced tuning with a big, open soundstage and punchy dynamics that punch way above its weight. Sure, the vocals could be a bit more forward, but for the price and the tech crammed inside pluse the dongle DAC and SoundCocoon tips, I’m more than happy to forgive that.

If you’re after a budget-friendly set that combines a fun, energetic sound signature with impressive technical chops, the Aurora Ultra might just be your new favorite travel companion—tiny enough to slip in a pocket, but with a sound that’s anything but small.

Kiwi Ears has been on a roll lately, cranking out new IEMs as if they’re trying to set a world record. When Astral and Septet are still stuck somewhere in the postal limbo, yet Kiwi Ears has already dropped the Étude, a tribrid set that’s part of their relentless march forward. Fittingly named, “Étude” is a term for a musical study piece designed to sharpen skills. Judging by how this IEM sounds, it’s clear that Kiwi Ears is indeed sharpening theirs.

On paper, the Étude is an impressive concoction: a single beryllium-plated dynamic driver, three balanced armatures, and the star of the show, the Kiwi Vibration Transducer (KVT), their very own bone conduction driver.

Whats in the box? check ount my quick unboxing video of the Kiwi Ears Etude.

Build and fit
The Étude is definitely the chunkiest IEM in my collection. It has a substantial presence, with thick, semi-translucent resin shells that let you glimpse the drivers inside if you hold them up to the light. Despite that chunky build, they’re surprisingly lightweight—no ear fatigue here, even after long listening sessions.

from left to right: Kiwi Ears Etude, Kiwi Ears Astral, Apevoix Grit

The fit is comfortable and snug, with a solid seal that does a great job of keeping outside noise at bay. I was a bit worried at first that the extra bulk might make them feel awkward in the ears, but Kiwi Ears clearly took ergonomics into account. Once you’ve got them in, they pretty much disappear.

The faceplates deserve a shout-out too. They’re adorned with an eye-catching pattern that manages to be both subtle and striking—a bit of flair that sets them apart from the sea of plain resin faceplates out there.

The Étude driver arrangement:

1 dynamic driver with a beryllium-plated diaphragm for a lively, powerful bass response

3 balanced armatures to handle mids and treble with finesse

1 bone conduction driver (the Kiwi Vibration Transducer or KVT) to add a tactile dimension to the sound



Bass
The Étude’s bass is nothing short of impressive. It’s tight and remarkably well-controlled, avoiding any sense of bloat or muddiness that can plague less refined sets. The beryllium-plated dynamic driver delivers punchy, authoritative hits—bass notes land with satisfying impact and speed. But what truly sets the Étude apart is the KVT (Kiwi Vibration Transducer).

The KVT introduces a subtle, physical vibration that you can actually feel beneath the music. It’s not overwhelming or gimmicky—more like a gentle rumble that adds an almost tactile layer to the low end. It’s the kind of bass you not only hear but also sense, adding depth and realism that makes you sit up and take notice.

Subbass reaches deep without smearing into the midrange, offering that satisfying rumble that’s tight and textured. Midbass notes are clean and agile, giving kick drums and bass guitars a lively, natural weight. And there’s a curious little detail too: when you pause the music, you can catch a faint resonance lingering for a split second, like a soft echo that hints the KVT is still there, humming along.

Overall, it’s a bass presentation that’s precise, dynamic, and engaging—never boomy or overdone. It perfectly balances technical control with musical warmth.

Midrange
The midrange is where the Étude shows its maturity. Vocals come through beautifully—lush, detailed, and with a natural presence that doesn’t feel forced. Whether it’s the soulful croon of a jazz singer or the bright energy of pop vocals, there’s a smoothness and clarity that makes them stand out without overpowering the rest of the mix.

Instrumental timbre is another highlight. Guitars have a sweet, organic warmth that never sounds plasticky or artificial, while pianos and strings have a gentle resonance that makes them feel alive. There’s a wonderful sense of layering too—each instrument and voice occupies its own little pocket of space, contributing to a cohesive, well-structured presentation.

What I particularly appreciate is how well the midrange balances presence and smoothness. It doesn’t lean too far forward or get lost behind the bass—it’s just perfectly placed, with a weight and body that feels satisfying and complete. It’s the kind of midrange that makes everything feel effortless and immersive, drawing you in and keeping you there.

Treble
The Étude’s treble is a real treat. It’s airy and extended, letting those upper frequencies breathe without a hint of harshness or sibilance. High hats and cymbals shimmer with a natural sparkle that adds just the right amount of brilliance—nothing overly etched or piercing, just a refined, sweet top end that keeps things lively and engaging.

What really impresses me is the sense of balance in the treble. It’s detailed and revealing, letting you pick up on micro nuances and delicate overtones that some IEMs tend to gloss over. Yet, it never feels aggressive. Even during busy tracks with lots of upper-frequency action, the Étude maintains a sense of composure and polish that’s easy on the ears.

When I compared it directly with the more expensive Apevoix Grit, the differences became clear. The Étude’s treble sounded more controlled and less peaky. Separation and layering were also noticeably better—cymbal hits and string harmonics felt cleaner, more defined, and decayed in a way that felt natural rather than abrupt.

Overall, the Étude’s treble complements its balanced, mature tuning perfectly. It’s detailed, spacious, and musical—proof that you can have both refinement and sparkle without ever sacrificing comfort.

Technical Performance
Technically, the Étude punches above its weight. Imaging is precise, and instruments are rendered with pinpoint accuracy in a nicely sized soundstage. While the stage isn’t cavernous, it has a satisfying width and depth that allows everything to breathe. Separation is excellent, and the transitions between instruments feel natural and cohesive. Despite its 10Ω impedance and 104dB sensitivity, the Étude pairs well even with modest sources, scaling up nicely with a good DAC or amp.

The Bone Conduction Difference
The KVT driver in the Étude is far from a gimmick—it’s genuinely something special. Unlike typical bone conduction drivers, the KVT doesn’t just add a faint rumble or slight tickle. Instead, it injects a palpable, almost physical sense of depth into the music that you can actually feel when the bass notes land.

It’s not a thumpy, overdone kind of feeling. Rather, it’s a gentle but persistent vibration that subtly reinforces the low end, giving it an addictive tactility. It’s like a low, satisfying thrum that resonates through the music, adding another dimension to the listening experience.

I found myself gravitating back to tracks with rich basslines and big drums just to feel that tactile sensation again—it’s hard to resist! It makes the Étude not just sound dynamic and full-bodied, but also feel dynamic in a way that’s rare in traditional IEMs.

Kiwi Ears Étude vs. Apevoix Grit:
I measured the Kiwi Ears Étude and noticed an interesting artifact in the upper midbass region—likely the bone conduction driver flexing its muscles. It adds a subtle resonance that becomes audible when you pause the music, lingering in the air for a brief moment.

On paper, both the Étude and the Apevoix Grit graph similarly and share a close overall tuning. But as soon as you start listening, the differences become obvious.

Let’s start with the bass. The Étude’s subbass is tight and controlled, delivering satisfying rumble without veering into muddiness. In contrast, the Grit’s low end feels looser and a bit boomy—like it’s more about quantity than quality. For some, that extra thump might be fun, but I prefer the precision and discipline of the Étude’s bass.
The real magic of the Étude, though, comes from that bone conduction driver. It adds a layer of tactility that you don’t just hear—you feel it. It’s subtle but alive, bringing an almost physical dimension to the low end that’s addictive. It’s like the bass wraps itself around you, making the listening experience more immersive and engaging.

When it comes to mids and treble, the Étude also pulls ahead. Vocals sound clearer, details pop out more effortlessly, and everything feels more spacious. The Grit’s upper mids and treble can sound a bit smeared by comparison—like they’re playing catch-up with the bass. In side-by-side listening, the Étude’s cleaner separation and better resolution make it feel more refined and confident.

Soundstage-wise, they’re in the same ballpark—neither is cavernous, but the Étude’s imaging is sharper and more holographic. Instruments are more precisely placed, giving a sense of dimension and realism that’s hard to ignore.

Even though the Grit is the pricier of the two and has a cool storage case that’s hard to resist, the Étude ultimately delivers the better overall package. Its more tactile bass, refined midrange, and superior technical performance make it a more compelling and satisfying listen—especially if you’re after something that feels more alive and engaging.

In the end, the Étude isn’t just about good measurements or graphs—it’s about the magic it weaves when you press play. And that, to me, makes it the better value and the more rewarding choice overall.

Final Thoughts
The Kiwi Ears Étude is one of those rare IEMs that manages to blend innovation and musicality in a way that feels genuinely exciting. With its tribrid setup and that lively KVT bone conduction driver, it brings a physicality and texture to the sound that’s hard to find anywhere else. It’s the kind of thing you don’t just hear, you feel it, and that makes every track come alive in a way that’s both fun and surprisingly immersive.

What really stands out for me is how well the Étude balances everything. It’s got tight, punchy bass that doesn’t get sloppy, mids that are lush and natural, and treble that sparkles without getting harsh. Plus, the technical performance is top-notch: excellent detail retrieval, solid imaging, and a tuning that manages to be both engaging and non-fatiguing.

For the price, the Étude really punches above its weight. You’re getting a level of refinement and physical impact that usually costs way more, and it does it without sacrificing musicality. Whether you’re analyzing every note of your favorite jazz track or just kicking back with some lo-fi beats, the Étude feels like it’s built to keep you listening just a little bit longer.

In short? It’s a great mix of refinement, detail, and good old-fashioned fun. And that’s what makes it such a standout.

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.

There are IEMs that sound good. Then there are IEMs that change how you feel about sound. The Kiwi Ears Septet is firmly in the latter category. I wasn’t ready for what this set delivered—and honestly, that’s what makes it special. Kiwi Ears has been releasing solid hits lately with the Aether, Airoso, and Astral, but the Septet? This one’s a whole different beast.

Let’s start with the configuration—because honestly, it reads like something dreamed up in an audiophile wet dream: 1 Dynamic Driver, 4 Balanced Armatures, 1 Micro Planar, and 1 PZT driver, all packed into an open-back shell. That’s seven drivers per side, each handling different parts of the frequency spectrum like a well-rehearsed orchestra.

Now, this might sound like a classic case of “more is more” on paper (ahem, KZ) but here’s the thing: it’s not just marketing fluff. It actually works, and not just in a “technically impressive” kind of way—it works in a musical way. The synergy between the drivers is surprisingly seamless. There’s no awkward crossover dip, no Frankenstein-tuning syndrome where each driver feels like it’s pulling in a different direction. Instead, you get a coherent, expressive sound that feels alive and layered.

But—and this is important—you have to feed it power. The Septet isn’t one of those IEMs you casually plug into your phone and dongle and expect magic. Give it proper amplification, and it opens up like a well-aged bottle of wine. The stage widens, the micro-detail sharpens, and the low-end firms up with a sense of control and authority. The magic doesn’t just come from the driver count it’s unlocked when you drive it like it deserves.

This isn’t just a specs monster. It’s a carefully crafted quadbrid beast that delivers when given the right conditions. Treat it well, and it’ll sing.

Whats in the box? Here is my quick unboxing video of the Septet.

Comfort & Build – Sleek, Solid, and a true open-back IEM
The Septet’s shells are crafted from a sturdy metal alloy, yet they feel surprisingly lightweight and ergonomic, especially considering all the tech packed inside. They sit comfortably in the ear without any sharp edges or awkward angles, and after a while, you almost forget you’re wearing something with seven drivers inside.







The open-back faceplate isn’t just there for show—it’s both functional and beautiful. That intricate grille design is the gateway to the Septet’s expansive, speaker-like soundstage. Of course, that also means isolation takes a back seat. These aren’t your grab-and-go IEMs for noisy cafes, airplane cabins, or sneaky "video sessions" when someone’s asleep next to you—you know what I mean, hehe.



But for home listening? For quiet evenings with a good DAC, a hot double shot espresso, and your favorite playlist? The Septet is a total joy. The comfort, build, and open-back magic all come together to make it feel less like an IEM and more like a tiny high-end speaker system that just happens to sit in your ears.



Bass – Controlled Power
The Septet’s bass is one of those rare performances that feels both disciplined and deeply satisfying. Thanks to the dynamic driver handling the low end, there’s real sub-bass presence that digs deep when called upon. It doesn’t try to steal the show, but when the music asks for rumble, the Septet answers with authority. There’s this subtle growl to low frequencies—especially in electronic, cinematic, or bass-heavy tracks—that feels like it’s coming from a much larger speaker setup.

But what I love most is the control. The bass doesn’t bleed into the mids or cloud the mix. It’s got that fast, tactile punch in the midbass that makes kick drums sound snappy and bass guitars feel agile and well-textured. Whether you're listening to upright jazz bass or layered EDM drops, the articulation remains tight and expressive.

And despite the muscle, it’s still musical. You can follow the shape and tone of bass notes—not just feel them. That balance of impact and restraint shows thoughtful tuning, and it allows the Septet to remain versatile across genres. It's bass with both brawn and brains—you get the emotional energy without sacrificing the technical cleanliness.


Midrange – Natural, Expressive, and Soulful
The mids strike a gorgeous balance between detail and warmth, It walks that delicate tightrope between Detail, clarity and warmth, delivering a presentation that feels alive never too sharp, never too soft. Vocals come through with a fullness and emotional weight. Voices feel intimate and human, like they’re right there with you in the room.

What really impresses me is how the Septet handles instruments. Acoustic guitars sound rich and woody, piano keys have proper weight and decay, and string sections carry that natural resonance and body that make them so captivating in real life. It doesn’t just reproduce notes—it expresses the textures in the playing. You hear the finger slides, the bow friction, the subtle pedal decay. There’s real nuance here.

Thanks to the open back shell and well-implemented balanced armatures managing the midrange, there’s a kind of speed and precision to the sound that lets details shine through without sounding clinical or cold. It’s articulate, yes, but never sterile. And honestly, if you’re still worried about “BA timbre” don’t be. We’re way past the era where balanced armatures had that dry, plasticky tone. The mids here feel every bit as natural and organic as a well-tuned dynamic driver. Kiwi Ears has clearly tuned these with musicality in mind.


Treble – Very airy, Extended, Never Harsh
Treble is where a lot of multi-driver sets stumble—but not on the Septet. Here, the treble is nothing short of elegant. It’s extended and detailed, with a natural sense of air that gives the entire presentation a feeling of openness and space. Hi-hats shimmer, cymbals crash with texture, and ambient micro-details float effortlessly through the whole mix.

What’s even more impressive is how smoothly it’s delivered. The micro planar and PZT drivers are clearly doing some heavy lifting here, bringing resolution and sparkle without turning the highs into a splashy or fatiguing mess. Treble here doesn’t jab at your ears—it lifts the music up and lets it breathe. You get all the clarity and air you’d want for classical, jazz, or ambient genres, but also the dynamic bite needed for rock and metal.

Even on brighter recordings, the Septet resists becoming sibilant or harsh. It’s confident, not aggressive—delivering detail without edge. The top end feels like the final touch on a very carefully layered soundscape, adding just the right amount of brilliance to keep things exciting.

Soundstage & Imaging – A Room With No Walls
The moment you hit play on the Septet, it becomes clear—this isn’t your average IEM. The open-back design plays a huge role here, and the result is a soundstage that feels… well, liberated. There’s a real sense of space, width, and even depth, something that’s often tough to nail in the in-ear format. It doesn’t just sound big—it sounds alive. Like you’re sitting in a venue, not just listening through a device.

What really floored me is the imaging. Notes don’t just appear in the left or right channel—they travel. Sounds move across the field with such precision and vividness that it feels almost binaural at times. You can pick out where a guitar is being strummed, where the hi-hat sits in the mix, or where a vocal reverb trail fades into the distance. Instruments aren’t just present—they’re placed. That level of layering and separation lets every element breathe and tell its own story.

Even in complex arrangements, the Septet doesn’t collapse or smear. It just opens up wider. It’s the kind of staging that makes familiar tracks feel new again you start noticing background textures and room reverbs you never realized were there.

Synergy & Pairing – Feed It Well, and It Sings
I’ve been pairing the Septet with the Fosi Q6 DAC, and let me tell you—this combo is magic. The AKM chip inside the Q6 adds a touch of warmth and smoothness that really complements the Septet’s vibrant character. It gives the mids a bit more richness and helps the highs float just a little more effortlessly, without losing that incredible air and separation.

But here’s the thing: the Septet isn’t your average plug-and-play IEM. This set demands a good source. It’s not just about volume—it’s about dynamics, current, and headroom. You’ll need something with a clean, powerful output to really unlock what these drivers can do. When underpowered, it sounds decent—but push it with a proper source and higher listening levels, and the Septet transforms. Suddenly the bass tightens, low-end control improves, and tiny microdetails come forward with confidence. Imaging sharpens, treble opens up, and the whole sound becomes more holographic.

This is one of those IEMs where you want to turn it up—not to chase volume, but because it rewards you with more depth and energy the further you push it. I wouldn’t call it inefficient, but let’s just say it prefers a strong cup of coffee in the morning. Treat it to a good DAC or DAP with solid power, and the Septet will absolutely return the favor with a performance that feels well above its price point.





Here’s a breakdown of how the Kiwi Ears Septet pairs with each of the sources i own, taking into account the IEM’s open-back design, unique 7-driver quadbrid setup, and its demanding drivability:




1. Fiio K11 R2R
Pairing: Beautifully textured and controlled
The Septet and K11 R2R make for a highly musical combo. The R2R DAC adds organic richness and a velvety smoothness across the mids and highs, complementing the Septet’s natural tone. It also tightens the bass, giving it just enough punch without turning it bloated. This pairing is more about texture and emotional engagement than brute resolution. Vocals, especially female ones, come alive with intimacy and warmth.
• Strengths: Lush mids, relaxed treble, great timbre
• Watch for: Slightly softer transients—not the most analytical pairing
• Ideal for: Jazz, acoustic, vocal-forward genres



2. Fosi Q6 (AKM-based DAC)
Pairing: Smooth, mellow, and easygoing
The Q6’s warmish tilt and soft treble edges pair well with the Septet’s detail-forward presentation. This pairing leans smoother and slightly relaxed in transients, ideal for long, non-fatiguing listening sessions. Imaging is still solid, but the Q6 rounds off some of the more aggressive edges, giving the Septet a cozy, more “musical” flavor.

• Strengths: Warmth, smoothness, great for casual listening
• Watch for: Slight loss of sharpness and micro-detail
• Ideal for: Easy listening, chillhop, indie, deep house and bossa



3. Fosi MC331 (Tube Amp/DAC)
Pairing: Vintage soul meets modern precision
Pairing the Septet with the MC331 adds a subtle analog warmth and harmonic glow, especially in the mids and upper bass. The imaging becomes more "rounded" and the stage feels natural and atmospheric. It takes away some edge from the planar and PZT drivers, letting the music breathe. Power is still borderline though—you’ll need to crank it. the MC331 has a low power headphone output.

• Strengths: Tubey warmth, rich mids, added euphony
• Watch for: Slight veil over upper treble, reduced speed
• Ideal for: Vocals, strings, lo-fi, classic american jazz.

4. Fosi K7
Pairing: Punchy and technical with ample headroom
The K7 offers clean, balanced output with surprisingly good dynamics for its price. It provides enough power to wake up the Septet fully, improving bass grip and adding clarity across the board. The pairing is crisp, controlled, and a bit more analytical, though not dry. Great synergy if you want to explore the Septet’s technical potential.

• Strengths: Clarity, macro dynamics, staging
• Watch for: Slightly lean mids if you're used to warmer sources
• Ideal for: EDM, rock, orchestral, cinematic scores, all genre actually.



5. HiBy R6 III (DAP)
Pairing: Natural, dynamic, and effortless
The R6 III, with its clean Class A amp mode (R6 heats up like crazy and shorter battery life) and neutral-warm tonality, pairs extremely well with the Septet. It gives the IEM plenty of current while keeping the sound open and clean. This is one of the most balanced and synergistic pairings—no harshness, excellent layering, and enough power to fully open the Septet’s wide soundstage. It's also one of the few portables that makes the Septet truly sing on the go.

• Strengths: Well-rounded, dynamic, clean stage
• Watch for: Battery life dips in Class A mode
• Ideal for: All genres, especially instrumental and hybrid vocal-music mixes



6. Fiio JM21 (DAP)
Pairing: Small but surprisingly effective
The JM21 has a clean, slightly warm-leaning signature with good separation and decent power. It's surprisingly capable of pushing the Septet with a decent sense of control and dynamics—but don’t expect it to extract everything. At medium-loud volumes, it performs admirably, but you might miss some of the depth and layering compared to stronger DAP that is why i paired my JM21 with Topping nx7 amp.
• Strengths: Smooth tuning, great staging for a dongle
• Watch for: Slight compression at higher volume needs an amp.
• Ideal for: jazz, deep house, techno etc..

Overall Ranking by Synergy & Performance with Septet:

• HiBy R6 III (Class A mode) – Best all-round synergy, fully unlocks the Septet’s capability
• Fiio K11 R2R – Best for lush, musical listening with excellent tone. the k11 really pushes the septet to its full potential.
• Fosi K7 – Best for technical performance and power
• Fosi Q6 – Great for smooth, relaxed listening
• Fosi MC331 – Unique analog flavor, romantic midrange
• Fiio JM21 – Best compact option, solid but limited power.



Final Thoughts – The One That Took Me by Surprise
The Kiwi Ears Septet wasn’t just a pleasant surprise it’s a bit of a revelation. From the moment I first plugged it in, I knew I was hearing something different. This isn’t just another seven-driver hybrid—it’s a carefully crafted blend of technologies that come together with real synergy. There’s no single driver dominating the show. Instead, everything works in harmony: the DD for rich, controlled bass; the BAs for textured mids; the micro planar and PZT for graceful treble detail and air. Add in that open-back staging, and you’ve got a recipe that doesn’t just sound good it feels special.

It’s not a cold or analytical listen, nor is it a colored mess. The Septet lands right in that sweet spot between musicality and precision, where everything feels both engaging and technically impressive. It invites long sessions, deep dives, and rediscovery of old favorites.

If you’ve enjoyed previous Kiwi Ears releases like the Quintet, Airoso or Aether, the Septet feels like a culmination of that tuning journey—richer, wider, more immersive. Of all the Kiw Ears i've tried, the Septet is my personal favorite, it's simply special.

When Venture Electronics decided to name their dongle Devastator, they weren’t playing around. I mean, with a name like that, they’re setting the bar pretty high and you'd expect two things: (1) it better hit like a truck, and (2) it better not fall apart if you so much as breathe on it. VE nailed it. The Devastator isn’t just talk; it backs it up with real muscle both in sound and in build. No flimsy plastic, no weak sauce just pure, clean power packed into a body tough enough to survive the chaos of daily life, perfect for people who want legit, high-performance audio without stuffing a brick into their pocket.

But first, let me share my journey with Venture Electronics it started a long time ago — back when my descent into the Chi-Fi rabbit hole first began. It all kicked off with the legendary Monk earbuds.

I honestly don’t remember exactly how I first heard about them. What I do remember is that the Monk was everywhere people in the hobby were talking about it, hyping it up but finding one was a different story. It must have been sometime around 2009 to 2013 (the exact year’s a blur now and yes im old), but back then, the Monk wasn’t available in my country. No online stores, no easy way to grab one.

I had to ask a friend who traveled regularly to Hong Kong to hunt one down for me. Finally, after what felt like forever, I had the Monk in my hands — wrapped in a simple, cheap-looking plastic bag that somehow made it feel even cooler. It was raw. Authentic. Different from the Sonys, the Aiwa, audio-technica, sharp earbuds, and all the classic "Jap-Fi" gear I had been using before.

Venture Electronics was never your typical mainstream brand. From what I could tell even back then, they seemed to intentionally avoid the mainstream path. The Monk wasn’t just cheap — it could outperform a lot of the expensive Japanese earbuds I had. It was a real market disruptor, no question about it.

And slowly but surely, VE built a kind of cult following around their gear. We didn't call it a cult, though — we called it a clan.
The VE Clan. And proud to be part of it.

What i got from VE? heres my quick unbox video well more like unpacking video

Back to the Devastator. Its Minimalistic. Rugged. Zero drama unlike some facebook audio group i know thats full of it.

The chassis feels reassuringly dense and industrial, exuding durability from the moment you pick it up. It’s the kind of build that inspires confidence: safe to toss it in your bag, bump it around your desk, even drop it accidentally (not recommended, but we’ve all been there) it shrugs it off and keeps doing its job. It’s built like audio gear used to be: with function first.

I have the 4.4mm balanced version, and the included cable appears to be oxygen-free copper (OFC), with a good level of flexibility and a durable outer sheath. Nothing fancy here either—just practical, quality materials chosen with a clear sense of purpose.

It sticks to VE’s core philosophy: function over flashiness. The Devastator is built like a proper tool — sturdy, minimal, and unapologetically utilitarian. There are no unnecessary frills here. It’s lightweight yet tough, clearly designed to handle the wear and tear of daily use. No flashy RGB lights, no glossy fingerprint magnets — just a focused, purpose-driven dongle that gets the job done.

Power and Driving Capability
On paper, the Devastator’s specs are kind of wild for something this small:

• 110.2mW into 33Ω
• 57mW into 64Ω
• 24.8mW into 150Ω
• 12.8mW into 300Ω

The Devastator brings real-world muscle where it counts. Specs are one thing, but what really matters is how it feels when you plug in your gear and hit play. And in that regard, this little beast punches way above its weight class.

It powers just about any IEM you throw at it without breaking a sweat including all my planars and the Binary Dynaquattro which you really need power to open it up. — the kind that tend to make some dongles wheeze — are handled with ease. And if you're thinking full-size dynamic headphones around 150 ohms are too much for a portable compact dongle, think again. The Devastator drives them with surprising authority, delivering a sound that’s full-bodied, energetic, and punchy.

But it’s not just about volume or driving capability — it's the way it drives. There's a palpable sense of grip and control. Bass feels tight and commanding, dynamics come alive with satisfying impact, and the soundstage stays open and composed even when you crank it up.

Sound: Good, Clean Fun
The Devastator nails that sweet spot between precision and musicality. Its tonality leans just slightly warm enough to give the music a bit of soul and richness but it still stays true to the heart of the original recording. There’s no weird digital glare, no artificial sharpness trying to fake "detail" where there isn’t any.

Vocals come through with real presence — alive, textured, and emotionally engaging. Guitars have that satisfying bite and crunch without turning harsh, and bass lines thump with genuine weight and texture, not just hollow rumble. Everything feels lively and full-bodied, but still controlled and natural.

Importantly, nothing feels exaggerated or hyped up for the sake of sounding impressive. It’s not trying to grab your attention with boosted lows or sparkly highs — instead, it just lets the music breathe, presenting it in a way that’s honest, enjoyable, and incredibly easy to listen to for hours.

In a world full of gear that either tries too hard to be "fun" or goes too far into sterile, analytical territory, the Devastator strikes a balance that respects both the music and your ears. It’s good, clean fun.

Clarity and Detail
Despite its compact size, the Dev pulls off something pretty remarkable — the level of detail it delivers is seriously impressive. You can pick up those tiny, often overlooked moments in a track — the slight intake of breath before a singer belts out a chorus, the delicate decay of reverb hanging in the background, or the subtle texture in the basslines that usually get lost in the mix.

But what really makes it special is how it presents those details. It doesn’t shove them in your face or make the music sound sterile and overly analytical. Instead, the Devastator opens up a clean, natural window into the recording, letting you hear everything without feeling like the life has been sucked out of the music. There’s no unnatural etching or artificial sharpness here — just a faithful, honest rendering of what’s actually in the track.

Its detailed enough for critical listening, but still rich, musical, and easy to enjoy for hours. I find a lot of gear either sacrifices musicality for detail or blurs details for warmth, the Devastator somehow manages to do both — and does it really, really well.

Background Noise
The Devastator is quiet — even with sensitive IEMs. No hissing, no weird hums. Just clean, black backgrounds that let music breathe naturally.

Dynamics and Slam
The dynamics are lively and energetic, but never feel overdone or cartoonish. There’s a natural sense of ebb and flow, where quiet moments feel intimate and delicate, and big hits or sudden bursts of energy land with real authority.

There’s also enough headroom here to handle fast transients and wide dynamic swings without breaking a sweat. Whether it’s the sudden crash of cymbals in an orchestral piece, the gut-punching drop in an EDM track, or the raw, explosive energy of a classic rock anthem, it delivers the impact in a way that feels genuinely satisfying — not just loud, but more alive.

It keeps up with the music’s mood changes too, shifting gears instantly when a song demands it. You get the feeling that nothing is being held back no congestion, no flattening out of emotions. It’s the kind of performance that keeps you locked in, head bobbing, fully engaged.

Imaging and Staging
Wide enough to not sound trapped in your skull, and clean enough to pick out who’s playing what without a map. Not exactly “Stadium” levels of stage, but seriously good for something this size.

Final Verdict
The Venture Electronics Devastator is a reminder that you don’t need some overdesigned, spaceship-looking dongle packed with blinking lights and a dozen “revolutionary” features just to get amazing sound on the go. Sometimes, you just need a company that actually knows what they're doing — and doesn’t overcomplicate things. Kudos to Lee and the VE team for keeping it real.

If you like your gear simple, honest, powerful, and with a very cool name the Devastator is a no-brainer. It’s not trying to flex with fancy marketing buzzwords or chase clout. It’s just here to quietly (and sometimes not-so-quietly) wreck your eardrums — in the best, cleanest, most respectful way possible.

And honestly? That’s way cooler. It’s the kind of gear you forget about because it just works.

Final Rating:
• Sound: 9/10
• Power: 8/10
• Build Quality: 9/10
• Flashiness: 2/10 (and proud of it)

The Ziigaat Lush doesn’t come storming into the room with a spec sheet that screams for attention or a fancy modular cable to show off. In fact, it might even fly under the radar at first glance. But give it some time—actually listen—and you’ll discover that this is an IEM that plays the long game. It doesn’t need to shout to make a statement. There’s a quiet confidence in how it handles your music, like it knows exactly what it's doing—and it does it really, really well.

This isn’t the kind of gear that relies on gimmicks or over-the-top marketing. The Lush earns its stripes the old-fashioned way: by delivering a satisfying, polished sound that keeps you coming back. It's the kind of IEM that might not wow you in the first five seconds, but wins you over in the next five hours.

Whats inside the box? here is my quick unboxing video of the Ziigaat Lush.



Unboxing and Accessories
The Lush arrives with a solid set of accessories, including a pair of foam tips and multiple sizes of silicone tips—one of which features a bright orange core that surprised me in the best way. It’s rare that I stick with stock tips, but after some tip rolling (narrow bore, wide bore—you name it), I kept circling back to these. They strike a great balance in seal, comfort, and acoustic synergy.

What really caught my attention, though, was the case. Ziigaat didn’t go the cookie-cutter route here. Instead of the usual compact clamshell. you get a flatter, wide square-shaped case with a mesh compartment inside. The elastic mesh holds accessories securely, preventing that usual tangle of tips and adapters we all know too well. It’s a small thing, but it speaks to a kind of thoughtful design that I appreciate.

Build and Fit
The shells are made from a glossy resin, and they carry that signature Ziigaat ergonomic shape. They nestle into my ears comfortably with no hint of pressure or fatigue even after hours of listening. The design is slick—stealthy, almost Gotham-esque. The dark, moody faceplates give off a Bruce Wayne-on-vacation kind of vibe: understated but with style.
The cable is... okay. It’s a glossy, braided affair that’s a bit stiff for my taste, and the version I have uses a 3.5mm non-modular termination. It gets the job done, but it doesn’t match the finesse of the shells or the tuning. Swapping it out might be worth considering if you’re into cable upgrades.

Under the hood, the Lush sports a 1DD + 4BA hybrid setup, and it’s marketed as a studio monitor. That can mean different things depending on the execution—but in this case, Ziigaat nailed it.

Tuning and Tonality
This is a neutral-balanced set done right. The Lush is transparent, smooth, and natural, with no one frequency trying to steal the spotlight. There’s a real sense of honesty to the sound—it doesn’t embellish, it just presents. And that’s something I didn’t think I’d enjoy so much.

I’m usually drawn to thicker, richer, more emotive tunings. I like my sound a bit romanticized. But the Lush made me pause. It helped me better understand what a well-implemented neutral tuning could do. It doesn’t demand a curated playlist. It doesn’t cherry-pick genres. It simply plays everything well—and that’s rare.

If you’ve ever felt like certain IEMs dictate what you listen to (I definitely have), the Lush breaks that cycle. You don’t need to chase the perfect track. Just hit shuffle and go. Whether you're focusing or multitasking, it delivers a consistent and non-fatiguing sound that's even great for background music.

Bass
The bass on the Ziigaat Lush feels like a thoughtfully tuned foundation—never overbearing, never undercooked. It strikes a nice balance between subbass and midbass, giving you just enough of both to keep things grounded and engaging.
The subbass isn’t the kind that rattles your skull, but it’s definitely there when the music calls for it. It offers a gentle, well-controlled rumble that adds depth without drawing too much attention to itself. Think of it as a subtle floorboard vibration rather than a ground shake—it supports the music without stealing the spotlight.

The midbass, on the other hand, carries a bit more personality. It’s got a warm, textured presence that gives kicks and bass guitars a satisfying thump—nothing bloated, just enough punch to feel lively. The decay is tastefully done too, trailing off naturally so the notes breathe a bit, but never feel sluggish.

What really stands out is the control. The bass knows its boundaries. It doesn’t bleed into the mids or create any sort of unwanted bloom. It complements rather than competes with the rest of the frequency range, which is exactly what you want in a well-tuned IEM. This kind of restraint shows that the Lush isn’t trying to impress with brute force—it’s going for finesse, and it mostly nails it.

Midrange
This is where the Ziigaat Lush really starts living up to its name. The midrange is, quite simply, a pleasure—smooth, natural, and emotionally grounded in a way that keeps you listening longer than you planned.

Vocals are a standout here. Whether it’s the smoky depth of a male singer or the delicate shimmer of a female voice, the Lush captures them with a sense of realism that feels effortless. Tonality is spot on—nothing feels pushed or hollowed out. They’re positioned just right in the mix, never shouting in your face but never hiding in the shadows either. It’s that “just right” kind of tuning that makes voices feel honest and present.

Instruments come through with an organic, textured character that feels tactile and believable. Guitars have body and string definition, pianos sound full and nuanced, and acoustic elements in particular really shine. There’s a gentle warmth in the mids—not syrupy or overly rich, but enough to breathe life into the music and smooth out any digital harshness. It doesn’t cross into coloration, though. The warmth is subtle, serving emotion rather than altering the intent of the track.

What ties it all together is the linear smoothness of the presentation. There's no weird dips or peaks here—just a consistent, easy flow that makes the Lush a perfect companion for longer sessions. It doesn’t fatigue, and it doesn’t try to impress with over-sharpened detail. Instead, it focuses on delivering a clean, emotionally honest performance. And really, that’s often what makes the difference between a good IEM and one that quietly earns a place in your daily rotation.

Treble
The treble on the Ziigaat Lush plays it cool—smooth, measured, and mature. It's definitely on the safer side of the spectrum, but that’s not a weakness. In fact, it's one of its strengths. This is the kind of treble that invites you to keep listening, hour after hour, without fatigue creeping in.

There’s a sense of control here that’s easy to appreciate, especially if you've ever dealt with an IEM that tried too hard to dazzle with sparkle and ended up feeling harsh or fatiguing. The Lush doesn’t go for that kind of flashy presentation. Instead, it offers just the right amount of air and lift to keep things feeling open and detailed, without ever crossing into sharpness or sibilance. It’s refined, not restrained.

Extension is solid—maybe not up to the level of a detail monster, but enough to render ambient cues, trailing cymbals, and spatial information with a nice sense of finesse. There’s clarity and layering, but it never comes off as clinical or overly analytical. This treble is more about complementing the overall balance than drawing attention to itself.

You won’t find a ton of sparkle or shimmer here, but that’s by design. It’s a well-mannered treble that plays nice with the warm, textured mids and the controlled bass. It helps create a cohesive, musical presentation—one that favors comfort and naturalness over aggressive detail. For many listeners, especially those sensitive to high frequencies, this kind of tuning will feel like a breath of fresh air.

Soundstage & Imaging
The Lush impresses with a soundstage that leans wide, especially left to right. It doesn't have that deep, three-dimensional layering that some planar or open-back designs aim for, but it still manages a nice sense of space. Imaging is accurate with solid separation—each instrument occupies its own spot without congestion, making it easy to follow complex arrangements.

Ziigaat Lush vs Kiwi Ears KE4: A Tale of Two "Meta" Tunings
Both the Ziigaat Lush and the Kiwi Ears KE4 fall under a similar tuning philosophy "meta" a neutral-balanced with studio-monitor intentions. But how they execute that vision differs in subtle but important ways. On paper, they might seem like siblings, but in practice, they have distinct personalities.

The Ziigaat Lush takes a smooth, softly neutral approach. It’s extremely balanced and inoffensive, the kind of tuning that just lets the music happen without pushing any frequency forward. The KE4, while still playing in the same neutral space, adds a bit of extra flavor—particularly in the subbass and upper mids.
Think of the Lush as the calm, detail-focused studio engineer, while the KE4 is the slightly enthusiastic assistant who still wants to stay accurate but adds just a touch of drama for fun.

Bass
Both IEMs are tight and controlled in the bass, but:
• The KE4 adds a noticeable subbass lift, which gives it more low-end presence, especially on genres like EDM, hip-hop, or cinematic scores. It’s still clean and doesn’t bleed, but the emphasis is there. It’s a bit more visceral when the track demands it.
• The Lush, in contrast, is more even-handed. The bass is split almost evenly between sub and midbass, with enough warmth and punch to stay musical but without stealing attention. It’s more about accuracy and texture than slam.

If you prefer a more grounded, balanced bass, the Lush has the edge. If you want a little more rumble and energy, KE4 might suit your taste better.

Midrange
Both sets have very solid mids, but again, they approach it differently.

• The Lush is all about natural tonality. Vocals—male or female—sound organic and lifelike, with just the right amount of warmth. It doesn’t feel colored or enhanced, just honest and smooth. Instruments like guitars and pianos come across with texture and space, but never edgy or forward.
• The KE4 pushes the upper mids slightly more, which gives female vocals and certain instruments more shine and presence. It's not shouty, but it’s more vibrant. This gives it a slightly more energetic and lively feel, which can be engaging, but sometimes borderline fatiguing at higher volumes or longer sessions, depending on your sensitivity.

So if you lean toward vocal-centric music and want a more lively and forward midrange, the KE4 delivers. If you’re after natural smoothness and long-session comfort, the Lush is the better companion.

Treble
Treble is one area where these two sets diverge in philosophy.
• The Ziigaat Lush plays it safe and smooth. It has enough extension to retain detail and air, but it never feels bright or piercing. It’s not a sparkle monster—it’s more about control and a fatigue-free presentation.
• The KE4 offers a bit more brilliance, especially around the lower treble. There’s more perceived detail and edge to cymbals, hi-hats, and micro-detail, which might appeal to those who want that extra bit of zing and clarity. However, it can come off a bit edgy depending on the track.

If you’re treble-sensitive or prefer mellow top-ends, Lush is your friend. If you enjoy a bit more energy and excitement up top, KE4 steps in.

Soundstage & Imaging
This is where things level out a bit.
• The Ziigaat Lush has a wider soundstage, particularly left to right. It gives a nice sense of space without artificial reverb or exaggeration. Imaging is precise and clean, with good separation and layering.
• The KE4 isn’t quite as wide, but it compensates with a slightly more intimate and engaging stereo image, especially for vocals and smaller ensemble pieces.

Both sets have excellent imaging for their price point, with the Lush pulling slightly ahead in overall spatial realism, while the KE4 offers a closer, more immediate presentation.

So which one should you go for?

Choose the Ziigaat Lush if:
• You want a truly neutral, studio-style tuning with no added coloration
• You prioritize long-term listening comfort and fatigue-free treble
• You listen to a wide variety of genres and want something versatile and smooth
• You value natural vocals and a relaxing presentation

Choose the Kiwi Ears KE4 if:
• You like a more energetic sound with subbass presence and a bit of treble bite
• You want more lively female vocals and upper-mid presence
• You prefer a closer, more engaging soundstage for vocal-heavy music
• You’re okay with slightly more aggressive tuning in exchange for excitement

In the end, both IEMs are excellent examples of how neutral doesn’t have to mean boring. The Lush is the laid-back precision tool, while the KE4 adds just enough flavor to keep things spicy. You can’t go wrong with either—it just depends on your preferred flavor of “truth.”

Final Thoughts
The Ziigaat Lush isn’t here to chase the latest hype or compete in a game of who can pump the most bass or crank the sharpest upper mids. It takes a different path—one that's a lot more rewarding if you're willing to listen. Instead of shouting for your attention, the Lush earns it quietly, with a sound that feels refined, mature, and genuinely satisfying.

What you get here is a studio-grade tuning that's true to the source, but never sterile or lifeless. It's transparent enough to reveal the finer details of a mix, yet still musical and inviting enough for those late-night sessions when you just want to relax and get lost in the music. It's a tricky balance to pull off, but the Lush walks that line with confidence.

This is an IEM built for the long haul. It doesn’t rely on gimmicks or exaggerated tricks to impress you in the first 30 seconds. Instead, it’s the kind of gear that wins you over slowly, revealing more of its strengths the longer you live with it. From its smart, tasteful tuning to its easygoing, genre-flexible character, the Lush feels like a natural fit for daily use—whether you're deep-diving into a favorite album or just soundtracking your day.

If you've ever wondered what "neutral" really should sound like—not flat and boring, but clean, organic, and genuinely musical—the Ziigaat Lush offers a pretty compelling answer. It’s one of those rare IEMs that doesn’t just perform—it becomes part of your listening routine without ever feeling like it’s trying too hard. And honestly, that's a harder and more impressive achievement than any spec sheet will ever show.

Tangzu is no stranger to making budget-friendly IEMs that punch above their weight, and with the release of the Wan’er 2, they’ve decided to give their much-loved entry-level model a well-earned sequel. Now, sequels in audio can be hit-or-miss—some improve, some stray too far—but the Wan’er 2? It genuinely feels like a matured, polished continuation of the original, and then some.

Whats in the Box? here is my quick unboxing video of the Tangzu Waner 2:

Build & Accessories: Familiar, but Better
The Wan’er 2 shares the same design and build as the original Wan’er SG—those familiar plastic shells, comfortable ergonomic fit, and that lightweight, forget-you’re-wearing-it feel. The faceplate has a sleek look, though nothing too flashy. This time around, Tangzu includes three pairs of the Tang Sancai standard bore tips, which are quite popular among budget IEM lovers for a reason—they fit well, seal better than average and on some cases can help if your IEM have some driver flex, and most importantly, they don’t mess with the tuning.

Another notable upgrade: the stock cable. It’s now more pliable, has a cleaner aesthetic, and my unit came terminated with a 4.4mm balanced jack, which is a welcome change for those of us living in balanced-output ecosystems. It’s not boutique-tier but it’s miles better than the old stock cable that shipped with the OG Wan’er.

Sound Impressions
Tested using the included Tang Sancai medium tips and various sources, the Wan’er 2 surprised me with its level of refinement. Both channels are perfectly balanced, and it’s one of those rare occasions where the graph really does tell the sonic story—smooth, mature, and tastefully tuned.

Bass:
The bass on the Wan’er 2 has grown up. Compared to the OG’s more fun and boosted low end, this new version dials things back a bit. The sub-bass is clean, with less rumble and a more neutral presence. The midbass is punchy and tight, with a slight roll-off that keeps things from getting too warm or muddy.
Don’t expect head-rattling slam or excessive texture down low—this is a disciplined, refined bass presentation. It’s not dry or dull, just more polite and controlled. Great for those who appreciate accuracy over fun, though bassheads may feel it’s a touch too polite.

Midrange:
The midrange is exceptionally well-tuned, with a natural tone and timbre that make both male and female vocals sound rich and realistic. There's a lush, organic quality to vocals that gives the Wan’er 2 an emotional, inviting character.
The upper mids are slightly more forward than the OG, which adds clarity and presence, especially for female vocals and acoustic instruments. However, there’s a gentle roll-off toward the lower treble, which softens the edge and adds a bit of warmth. It’s a nice balance—forward enough to be engaging, but never shouty or harsh.

Treble:
Treble here leans toward the laid-back side, which will be a blessing for treble-sensitive listeners. It’s clean and non-sibilant, with a decent amount of detail retrieval but not overly airy or sparkly. There’s just enough extension to keep things from sounding dull or veiled, but detail lovers might crave a bit more crispness.
This is a “sit back and enjoy” kind of treble—not one that throws every microdetail in your face, but one that lets the music flow smoothly without fatigue.

Soundstage & Imaging: Adequate and Competent
The soundstage is about average—not wide or deep enough to make you think you’re in a concert hall, but also not so narrow that it feels congested. It’s... just enough. What impressed me more was the imaging, which is actually quite precise for the price. Instruments are easy to locate, and there's a clear sense of left, right, and center.
Separation is okay—not bad, not spectacular. In complex passages, things can feel a little less defined, but for most genres and daily listening, it's entirely serviceable.

Comparisons

vs Kefine Delci
Both the Wan’er 2 and Kefine Delci sit in the ultra-competitive budget IEM space, and both are shockingly competent for their price—but they approach sound from different philosophies.
Tuning & Tonal Balance
• Wan’er 2 leans toward a neutral-warm Harman-inspired signature, with an emphasis on natural vocals, smooth mids, and a relaxed treble.

vs Tripowin Vivace

• Vivace, by contrast, leans into a fun-first tuning, with a bold V-shape, strong bass, and lively upper mids and treble. It’s unapologetically colored.
• Wan’er 2: Relaxed and musical, tuned for natural vocals and long-term listening
• Vivace: Energetic and punchy, tuned for excitement and contrast

Bass
• Vivace throws in big bass energy, especially in the subbass. It rumbles deep, slams hard, and unapologetically colors the sound.
• Wan’er 2 has a more restrained, controlled bass, with tighter subbass and less midbass bloom. It’s cleaner and more neutral down low.

• Vivace: big, fun bass with strong impact—basshead-approved
• Wan’er 2: tight and refined—better for balance and genre versatility
Midrange
• Wan’er 2’s mids are the highlight—natural tone, slightly warm, with good weight and excellent timbre. Vocals are front and center, lush and easy on the ears.
• Vivace’s mids are recessed, especially male vocals which can sound a little thin or veiled compared to the punchy bass and forward upper

mids.
• Wan’er 2: better mids, richer vocal presentation, more natural
• Vivace: more scooped mids, especially for male vocals

Upper Mids & Treble
• Vivace is brighter and more sparkly, with an elevated upper midrange that gives energy and bite to vocals and instruments. But it can be peaky and fatiguing at times, especially with female vocals or sibilant tracks.
• Wan’er 2 plays it safer—smoother and more relaxed in the upper mids and lower treble, but at the expense of microdetail and air.
• Vivace: energetic and detailed, but may get harsh at high volumes
• Wan’er 2: smooth and laid-back, better for treble-sensitive listeners
Technical Performance
• Detail Retrieval: Vivace reveals more microdetail and edge due to its treble lift, but Wan’er 2 handles macro detail and realism better.
• Imaging & Separation: Slight edge to Vivace due to the extra treble clarity, but Wan’er 2 keeps up with cleaner midrange layering.
• Soundstage: Both are average, but Vivace feels wider due to its brighter presentation.

• Vivace: feels technically sharper but also more artificial
• Wan’er 2: more coherent and organic

Build, Fit & Accessories
• Both are lightweight and comfortable, but the Wan’er 2 wins with the Tang Sancai tips and a better cable, especially with the 4.4mm option.
• Vivace looks flashier, but some may find the fit less secure due to its shape and nozzle angle.
Which One Should You Pick?
• Get the Wan’er 2 if you want something mature, balanced, and natural-sounding with rich mids and no harsh edges. Great for vocals, acoustic, lo-fi, jazz, and chillout music.
• Go with the Vivace if you want a bass-heavy, bright, and lively IEM for EDM, hip-hop, pop, or rock—something that wakes you up rather than soothes you.



vs Kefine Klean
Think of the Wan’er 2 as the smooth-talking charmer — warm, organic, and easy to listen to.
The Kefine Klean, on the other hand, is the clean-cut professional — more refined, balanced, and articulate, like a grown-up version of the Delci with polished shoes and a crisper accent.

Tuning & Tonality
• Wan’er 2 is tuned for warmth and musicality. It has a relaxed, slightly colored presentation that leans into smoothness rather than precision.
• Klean leans closer to a neutral-ish U-shape with tighter bass, lush mids, and a better-controlled treble. There’s more clarity and balance without sacrificing musicality.
• Wan’er 2: Warm, mellow, emotional
• Klean: Balanced, clean, more technical but still engaging

Bass
• Wan’er 2 bass is pleasant, moderately elevated but not particularly fast or textured. Subbass is cleaner than OG Wan’er, but overall it's more about presence than definition.
• Klean bass is tighter, punchier, and faster-decaying. Subbass has a more focused presence, and midbass is better controlled — overall, it's more articulate and “grown-up” sounding.

• Wan’er 2: Smooth, slightly rounded, less detailed
• Klean: Punchy, textured, well-separated

Midrange
• Wan’er 2 mids are its sweet spot — vocals come across as lush, organic, and weighty. Instruments sound natural but not ultra-detailed.
• Klean mids are cleaner, slightly more forward, and better separated. Vocals are vivid with excellent tonality, especially with the black nozzle which brings more air and crispness. It’s less warm than Wan’er 2 but more precise.

• Wan’er 2: Warm, intimate, forgiving
• Klean: Clear, well-separated, slightly brighter

Treble
• Wan’er 2 treble is laid-back and inoffensive. It avoids sibilance and harshness but lacks air and sparkle.
• Klean treble is better extended, more open-sounding, and has a gentle crispness that gives music more life and detail. Still smooth, but more present.

• Wan’er 2: Safe, non-fatiguing
• Klean: Smooth, but clearer and more revealing

Technical Performance
• Detail retrieval: Klean edges ahead, especially in micro-details and clarity.
• Soundstage: Both have average width, but Klean has slightly better depth and separation.
• Imaging & separation: Klean is more precise and cleaner, making it easier to track instruments in complex tracks.
• Dynamics: Klean is punchier and livelier; Wan’er 2 is softer and more laid-back.
Build, Fit & Accessories
• Wan’er 2 is lightweight and ergonomic. Its updated cable (especially in 4.4mm) and Tang Sancai tips are solid.
• Klean feels more premium with its metallic housing and sleeker design. Fit is just as comfy, and interchangeable nozzles (silver and black) give you mild tuning flexibility.
Which Should You Get?
• Go for Wan’er 2 if you want a cozy, warm, and relaxed IEM for chill listening — especially if you’re treble-sensitive or just want something easy and musical.
• Pick Klean if you want a more refined, technically capable, and balanced listen with better clarity and control — a great all-rounder that still feels enjoyable and not clinical.

The Wan’er 2 plays it safe but does it well — smooth, pleasing, and instantly likable.
The Kefine Klean steps it up with more polish, control, and resolution, making it the better option if you want something that can scale with higher-quality sources and more detailed music.



vs EPZ Q1 Pro
This is a bit like comparing a mellow jazz singer (Wan’er 2) with a high-energy pop vocalist (Q1 Pro).
Both are enjoyable and crowd-pleasing, but the Wan’er 2 goes for a smoother, more organic presentation, while the Q1 Pro is all about energy, clarity, and a more forward sound.
Tuning & Tonality
• Wan’er 2 is warm and mature, with a slightly relaxed tuning that emphasizes lush mids and smoothness across the board.
• Q1 Pro leans more into a modern Harman-esque tuning, with lifted upper mids and treble for added energy and sparkle. It’s the more vibrant-sounding IEM.
Summary:
• Wan’er 2: Warm, soft-edged, musical
• Q1 Pro: Clean, energetic, crisp
Bass
• Wan’er 2 has a tighter, more refined bass compared to the OG Wan’er. Subbass is clean, but there's not a lot of rumble. Midbass is punchy, slightly rolled-off, and doesn’t overwhelm.
• Q1 Pro’s bass is snappier and more elevated, especially in the subbass. It has better slam and a slightly more exciting low-end, though it can sometimes overshadow the mids if you’re sensitive to that lift.
Summary:
• Wan’er 2: Refined, less aggressive
• Q1 Pro: More impact, slightly boomier
Midrange
• Wan’er 2’s mids are lush, warm, and natural-sounding. Vocals — especially male — have a nice body and weight. Female vocals are smooth but not super forward.
• Q1 Pro’s mids are more forward and energetic, especially in the upper mids. Female vocals sound brighter and clearer, but there’s less warmth and body than the Wan’er 2. It’s cleaner but more prone to sharpness in shouty recordings.
Summary:
• Wan’er 2: Smooth, laid-back mids
• Q1 Pro: Clearer, more energetic, a bit leaner
Treble
• Wan’er 2 treble is laid-back, non-fatiguing, and forgiving. It doesn’t sparkle much, but it avoids harshness and sibilance.
• Q1 Pro’s treble is more pronounced — brighter, crisper, and better for detail retrieval. It can be more exciting, but also slightly fatiguing on longer sessions for treble-sensitive folks.
Summary:
• Wan’er 2: Soft, polite, gentle
• Q1 Pro: Brighter, more detailed, slightly aggressive
Technical Performance
• Detail retrieval: Q1 Pro has the upper hand — it brings out more texture and micro-details, particularly in the treble region.
• Soundstage: Both are fairly average, but the Q1 Pro feels slightly wider due to the brighter tuning and airier top end.
• Imaging & separation: Q1 Pro again edges ahead here — it’s easier to track instruments in complex tracks. Wan’er 2 is more blended and rounded, which some may actually prefer for casual listening.
• Dynamics: Q1 Pro sounds more lively and dynamic. Wan’er 2 is smoother but can come off a bit soft by comparison.
Build, Fit & Accessories
• Wan’er 2 keeps the same great ergonomic shell as the original, and now includes better tips (Tangzu’s Sancai tips) and an improved stock cable — especially if you got the 4.4 version.
• Q1 Pro has a more solid-feeling metal shell, a good-quality cable, and a decent set of tips. Its build feels more premium, but the fit may be a bit chunky for smaller ears.
Which Should You Get?
• Go for Wan’er 2 if you value smooth, organic mids, a laid-back presentation, and forgiving treble. It’s great for longer listening sessions, vocal music, and those sensitive to upper-mid sharpness.
• Pick Q1 Pro if you want energy, detail, and punch — a livelier, more dynamic IEM that works great for modern pop, EDM, and tracks where sparkle and speed matter.

The Wan’er 2 is the safer, more mature-tuned option. The Q1 Pro is sharper, more exciting, and technically a step ahead — but it demands a bit more tolerance for brightness and upper-mid energy.
If the Wan’er 2 is like sipping hot tea on a rainy afternoon, the Q1 Pro is more like an iced coffee shot before a workout. It just depends on what kind of energy you’re in the mood for.

vs Simgot EA500
These two IEMs may live in the same sub-$100 category, but the EA500 often punches above its class with bold energy and clarity, while the Wan’er 2 takes the more mature, easygoing route.

Tuning & Tonality
• Wan’er 2 follows a smoother, warmer Harman-inspired curve. It’s tuned to please — warm mids, relaxed treble, nothing offensive.
• EA500 comes with two nozzle tunings (red and black), both of which are much more energetic and revealing, with a clear focus on upper mids and treble clarity.
Summary:
• Wan’er 2: Smooth, warm, and easy to love
• EA500: Bright, vivid, and exciting — more “hi-fi” sounding
Bass
• EA500 bass is fast, clean, and responsive — not the most elevated, but it slams when needed with great control and texture, especially in the subbass.
• Wan’er 2 bass is more relaxed — still punchy and present, but more rounded and soft around the edges. There’s less texture and definition, though it’s pleasing for casual listening.

• EA500: Tight, technical, more dynamic
• Wan’er 2: Gentle, smooth, less detailed
Midrange
• Wan’er 2 midrange is arguably its strongest suit — vocals are natural, lush, and organic. There's warmth and emotional engagement here, even if not the most detailed.
• EA500 mids are more neutral and analytical — excellent detail retrieval, especially with female vocals, but also sharper and more forward, which may come off as shouty or hot to sensitive ears (especially with the red nozzle).

• Wan’er 2: Warm, smooth, relaxed mids
• EA500: Detailed, forward, more analytical mids
Treble
• EA500’s treble is lively and sparkly, with plenty of air and microdetails. It's where the EA500 pulls ahead of many sub-$100 IEMs — but it can also veer into fatiguing territory, especially at higher volumes or with brighter tracks.
• Wan’er 2’s treble is mellow, smooth, and free of harshness. It's easy to listen to but also a little rolled off — you’re getting comfort over detail.

• EA500: Crisp, airy, and revealing
• Wan’er 2: Relaxed and non-fatiguing, but less detailed
Technicalities
• Detail retrieval: EA500 takes this easily. Every pluck, reverb, or vocal nuance is more clearly rendered.
• Imaging & separation: EA500 is more precise, with sharper imaging and better instrument layering.
• Soundstage: EA500 feels wider and more open. Wan’er 2 is more intimate, “closer-in,” but not congested.
• Dynamics: EA500 sounds more alive and dynamic; Wan’er 2 is smoother, less punchy.
Build & Fit
• EA500’s metal shells feel solid and premium but can be a bit heavier. The mirror finish is pretty but a fingerprint magnet.
• Wan’er 2’s resin shells are lightweight and comfy with no sharp edges. Not as flashy, but ergonomics win here.
Stock accessories also favor the Wan’er 2, thanks to the Tangzu Sancai tips and upgraded cable (especially if you got the 4.4mm version). EA500’s stock cable is basic and tips may need replacing.
Which One’s Right for You?
• Get the Wan’er 2 if you want a more natural, chill, and warm sound that works well for long listening sessions — especially if you’re treble-sensitive.
• Go for the EA500 if you want a more energetic, detailed, and technically strong IEM — something closer to a mini reference tuning, especially with the red nozzle

Final Thoughts
The Wan’er 2 is like a cozy café on a rainy day — warm, smooth, and inviting.
The EA500 is more like a clean glass of sparkling water — refreshing, bright, and attention-grabbing.
Both are excellent in their own right — it just comes down to whether you're in the mood for comfort or clarity.

vs TINHiFi T7
They live in different price range, the Wan’er 2 and the T7 also feels like they’re playing in two different genres. One’s focused on musicality and balance, while the other leans more toward technical flair and treble-forward energy.

Tuning & Overall Tonality
• Wan’er 2 has a warm-neutral, Harman-inspired tuning that’s smooth, laid-back, and more focused on musicality. It sounds like it was designed to be inoffensive, enjoyable, and coherent.
• T7, in contrast, is a bit of an oddball—leaning bright-neutral, with noticeable upper mid and treble emphasis. It feels a little more “technical” in approach, but it may not be as easy on the ears over long sessions.

• Wan’er 2: musical, relaxed, natural-sounding
• T7: leaner, brighter, and more analytical
Bass
• T7’s bass is tight but lean—subbass rolls off early, and midbass isn’t particularly punchy either. It’s clean, sure, but lacks warmth and authority.
• Wan’er 2 offers more bass presence—not boomy, but more body and punch in the midbass. Subbass is modest but enough to add weight. It feels more natural and better balanced.

• Wan’er 2: fuller, more present bass with musical texture
• T7: clean but thin; bas tuning overall more detailed and higher resolution.
Midrange
• Wan’er 2 excels here—its mids are the star of the show. Vocals are smooth, tonally accurate, with a touch of warmth that makes instruments and singers sound inviting.
• T7’s mids are more sterile, especially the lower mids, which can come across as dry and slightly recessed. Upper mids are more aggressive, and female vocals can sound a bit shouty depending on the track.

• Wan’er 2: lush, warm, realistic vocals
• T7: clean but thin, more focused on upper mids
Treble
• T7 is brighter overall, with a forward treble that brings out sparkle and detail—but it can also be fatiguing or borderline harsh, at higher volumes.
• Wan’er 2’s treble is smoother and more laid-back, with enough air to give detail without being fatiguing. It’s a more relaxed listen but lacks the same microdetail that the T7 can reveal.

• Wan’er 2: smoother and safer
• T7: brighter and more detailed, but potentially fatiguing
Technicalities
• Imaging & Separation: The T7 has slightly sharper imaging, thanks to its leaner and brighter sound.
• Soundstage: Neither is exceptionally wide or deep, but the T7 can feel more open due to the treble focus, while Wan’er 2 sounds more intimate but layered well.
• Detail Retrieval: T7 pulls out more microdetails, but sometimes at the cost of tonal realism. Wan’er 2 sounds more “right” overall, even if it’s not as technically flashy.
Build & Comfort
• Wan’er 2’s resin shell is lightweight and ergonomic. It also comes with better stock tips (Tang Sancai) and an improved cable over the original.
• T7 has an aluminum shell, more premium in feel, but some people might find the fit tricky due to the weight and nozzle angle.
Which Should You Choose?
• Get the Wan’er 2 if you value smoothness, natural tonality, great vocals, and a fatigue-free sound. It’s the better all-rounder and more forgiving of poor recordings.
• Choose the T7 if you’re a fan of brighter, technical-sounding IEMs, and you prioritize detail retrieval and separation over warmth and musicality.
Final Thoughts
The Wan’er 2 feels like it was tuned by someone who really understands human ears and daily listening preferences. The T7, while impressive in certain technical areas, is more of a niche pick—great for detail lovers, but less emotionally engaging overall, but personally i still prefer the T7 for me its just better overall.

Final Thoughts: A Budget IEM That Aims Higher

The Tangzu Wan’er 2 is an honest, well-thought-out upgrade to the original. It may not be as instantly fun or bass-heavy, but it trades that raw energy for maturity, control, and better overall refinement. It competes in a category that’s increasingly crowded, yet it manages to hold its own by offering a cohesive, smooth, and musical sound that honestly feels like it belongs in a higher price tier.

If you’re after a budget IEM with natural vocals, a well-balanced tuning, and zero harshness, the Wan’er 2 is a strong contender. And if you're coming from the OG Wan’er and wondering if this is a worthy follow-up—the answer is yes, just don’t expect the same punch; expect something more grown up.

FiiO sent over a big, heavy brown box, and inside were the FiiO SA1 active bookshelf speakers along with the RR11 FM radio. After a brief wrestling match with the packaging (seriously, FiiO packs these things like they’re shipping fine china), I finally got them unboxed and set up for a quick test.

First impressions? These speakers feel rock solid. The build quality is reassuringly hefty, and they offer a surprising amount of versatility when it comes to connectivity. But what really caught my attention was the sound—despite their compact size, the SA1 delivers a full-range presentation with impressive clarity and depth. The two-driver configuration works harmoniously to produce a well-balanced sound, and for a speaker of this size, they have a remarkable presence.

One thing to note: the SA1 is back-ported, meaning bass response is influenced by placement. Position them near a wall, and you’ll get a noticeable boost in the low-end. This can be a good thing if you want extra warmth, but it might require some fine-tuning depending on your room acoustics.
Of course, a quick test isn’t enough to do these justice. This is actually my first time reviewing a set of speakers, so I’m excited to dive deep into their performance across different setups and genres. Let’s break it all down and see what the SA1 can really do.
Whats in the box? here is a quick unboxing video of the Fiio SA1.



Build and Design
The FiiO SA1 boasts a clean, modern aesthetic with a high-density MDF cabinet (12mm thick) and wood side panels i am not sure what kind of wood they use but i assume its the same one they use on the FT1 closed back headphones. The design helps reduce unwanted resonance and keeps vibrations under control. Each speaker has a reassuring weight, with the main unit at 1.7kg and the secondary at 1.6kg, quite heavy for its compact size but has a premium feel and looks.

One of my favorite design elements is the front panel, a simple yet classy look with a thick gunmetal gray metal bezel, It doesn’t scream for attention, but it has that understated, timeless vibe that blends well with different setups.




On right speaker, you get two physical control knobs and one power button—one for volume and input selection and one for bass, along with an RGB status indicator that provides visual feedback for different modes. The included remote control is a nice touch, making it easy to tweak settings without getting up from your chair but some controls on the remote works only when you are on bluetooth mode like the play/pause and track skip etc..



Specifications and Features
Under the hood, the SA1 is packed with high-quality components considering its budget friendly price.

• Drivers: 3.5-inch wood fiber mid-bass driver.3/4-inch aluminum-magnesium alloy dome tweeter.
• Amplification: Built-in Texas Instruments TPA3118 digital amplifier
• 20W per mid-bass driver, 5W per tweeter (independent four-channel power output)
• Frequency Response: 65Hz – 20kHz
• Inputs & Outputs:
• RCA/PHONO inputs (with a built-in LP phono preamp) for turntables
• 3.5mm AUX input
• USB Type-C (supports 96kHz/32-bit decoding)
• Coaxial input (up to 192kHz/24-bit)
• Optical input (supports 96kHz/24-bit audio)
• Bluetooth 5.4 (with LDAC, AAC, and SBC support)
• Dedicated subwoofer output (SUB OUT) for easy 2.1 expansion





Vinyl Turntable Compatibility
One of the more thoughtful additions to this device is its built-in phono preamp, making it easy to hook up a turntable without needing an external preamp. This is a great convenience, especially for those who enjoy the warm, nostalgic sound of vinyl but don’t want to deal with extra components cluttering their setup.

However, if your turntable already has a built-in preamp like the FiiO TT13 you’ll want to be mindful of your connection settings. In this case, be sure to switch the device to RCA input mode. Otherwise, you’ll be running a preamp into another preamp, which can lead to an ear-splitting jump in volume and potentially damage your speakers. Think of it like shouting into a megaphone that’s pointed at another megaphone things will escalate quickly, and not in a good way so double check and make sure it on RCA Mode when your turntable has a built-in preamp.



Sound Performance
I tested the SA1 across different music genres, from jazz and classical to rock and electronic, all in a flat EQ setting.

Bass
The SA1 delivers punchy, layered bass with good extension, especially considering its size. Placement is key here—put them near a wall, and the bass gets a natural boost. It’s tight and controlled rather than boomy, which is great for detailed low-end reproduction also at the back there is a rca out for an active subwoofer if you want that extra rumble.

Midrange
The SA1 delivers a natural, rich, and well-balanced midrange, striking that sweet spot between warmth and clarity. Vocals feel lively and engaging, with a slight warmth that adds depth without making them sound overly colored. Both male and female vocals are well-positioned in the mix neither too recessed nor too forward creating a presentation that feels open and natural. Guitars, pianos, and string instruments benefit from this as well, with clear articulation and accurate timbre, making them sound detailed and smooth. You can hear the subtle variances, like the delicate decay of piano notes or the crisp pluck of a guitar string, all without harshness or artificial sharpness.

Overall, the midrange feels effortless and immersive, making these speakers an excellent choice for vocal-centric music, acoustic recordings, or even movie dialogue where clarity and tonal accuracy are essential.

Treble
The highs are well-extended but not harsh. They strike a balance between detail and smoothness, ensuring you get plenty of resolution without fatigue. Cymbals, strings, and high-frequency details shine through without becoming piercing.

Overall, right out of the box the SA1 has a neutral and well-balanced sound with just a hint of warmth, making it easy to enjoy across different genres. Vocals are reproduced beautifully, coming through with clarity and natural tonality, which adds to the speaker’s engaging character. And despite the compact driver size, the bass still packs a punch, offering a satisfying low-end that remains tight and controlled rather than boomy. It’s a well-rounded sound that works just as well for music as it does for movies and gaming.

One thing that really stood out to me about the SA1 is how well it scales with volume. As you crank it up, the sound doesn’t just get louder—it actually improves. The dynamics become more engaging, the frequency response feels more extended, and the overall presentation gains a sense of fullness and depth.

The upper midrange, in particular, comes alive at higher volumes, revealing more micro-details and nuances that might be subdued at lower levels. Vocals sound more textured, instruments gain a greater sense of presence, and the treble gets a nice boost in energy without becoming harsh or fatiguing. It’s the kind of performance that makes you want to keep turning the dial up—just make sure your ears (and neighbors) are ready for it! hehe

(This are my sound impression without using the EQ or the 30 band PEQ, you can always tweak the sound when you connect the SA1 to the FiiO Control App via bluetooth.)



Soundstage & Imaging
I placed the SA1 on my desk, about two inches from the wall, and used my 3D-printed risers to angle them just right for an optimal listening experience. Right away, I noticed how precise the stereo imaging is—more focused on left and right separation rather than front-to-back depth. However, it still has a wide enough stage to give each instrument a distinct place in the mix.

While the soundstage isn’t the widest I’ve encountered in speakers of this size, it still creates a satisfying sense of space, especially in a nearfield setup. The sound remains well-defined and immersive, with enough separation to let each element breathe. There’s no artificial exaggeration, just a natural and cohesive presentation that pulls you into the music without feeling overly constricted.

Wireless & Digital Performance

LDAC Bluetooth & Hi-Res Audio
Pairing the SA1 with a phone via Bluetooth 5.4 (using LDAC) The high-bitrate streaming (up to 990kbps) means that lossless files sound almost as good as wired connections, making Bluetooth a viable option for hi-res playback and also practical when you want to place the SA1 on a diffrent place far from the source, so no unsightly wires to worry about.

I paired the SA1 with my FiiO TT13 turntable and set the speakers on a separate table about five meters away. Placing them on the same surface wasn’t an option—doing so could introduce unwanted vibrations, causing the turntable stylus to pick up resonance from the speakers and create a bass loop.

Pairing the SA1 and TT13 via Bluetooth was quick and hassle-free, and the connection remained stable throughout my listening sessions. That said, it’s a bit disappointing that the TT13 doesn’t support LDAC, especially since the SA1 does. It would have been nice to take full advantage of higher-resolution Bluetooth streaming, but the standard codec still delivered a solid listening experience.

USB, Coaxial, and Optical Inputs
The wired digital inputs on the SA1 offer clean, distortion and interference free audio, making them ideal for connecting to a variety of sources like PCs, gaming consoles, and external DACs. If you are into streaming music, gaming, or watching movies, these inputs ensure a stable and high-quality signal path without the interference or compression that can sometimes come with wireless connections.

The USB Type-C input supports 96kHz/32-bit decoding, allowing for high-resolution playback from modern digital sources. This means you can plug in your laptop, smartphone, or DAP and enjoy detailed, high-fidelity sound with excellent clarity and dynamics.




Pairing with the FiiO K11 R2R and FiiO JM21
One of the most enjoyable setups I tested was pairing the SA1 with the FiiO K11 R2R DAC via its RCA line-out, using the FiiO JM21 as my source DAP. Out of all the combinations I tried, this one stood out as my clear favorite—and for good reason.

The SA1’s monitor-like tuning pairs beautifully with the K11’s R2R architecture, allowing its distinct musicality and technical finesse to shine. There’s an undeniable organic warmth in the mids, giving instruments and vocals a more natural, lifelike quality. The soundstage feels deep and immersive, with an almost analog-like smoothness that softens harsh edges without sacrificing detail.

What makes this pairing so special is that the SA1 doesn’t impose too much of its own character on the sound. It maintains clarity, resolution, and excellent separation, allowing the K11’s rich tonal balance and nuanced dynamics to take center stage. It’s a perfect blend of accuracy and musicality, clean and revealing, yet effortlessly engaging.



Final Verdict
The FiiO SA1 active bookshelf speakers offer a well-rounded, high-resolution audio experience, making them a fantastic choice for music lovers, gamers, and casual listeners alike. They deliver detailed, well-balanced sound that is both engaging and easy to listen to, striking a nice balance between clarity and warmth.

What sets the SA1 apart is its versatile connectivity—it supports Bluetooth with LDAC, a built-in phono preamp for vinyl enthusiasts, and DSP with 30 Band PEQ for precise sound tuning via the FiiO Control App. These extra features allow you to tailor the sound to your preferences, making them even more adaptable to different listening environments.

Despite their compact size, the SA1 is surprisingly powerful and can easily fill a decent-sized room with rich, dynamic sound. They punch well above their 3.3kg weight in terms of performance, delivering an audio experience that feels premium for the price. If you listening to hi-res files, streaming wirelessly, spinning vinyl, or gaming, the SA1 provides an excellent, refined and enjoyable listening experience. Considering the performance you get for the price, they stand out as one of the best choices in their category. The FiiO SA1 is an easy recommendation from me

A compact, feature-packed, and well-tuned speaker system that’s hard to beat at this price.

The Kiwi Ears Aether is an IEM that immediately piqued my curiosity. With a 15.3mm planar magnetic driver, it features one of the largest planar diaphragms I’ve encountered in an IEM. Naturally, I expected a big, bold, bass-heavy, and colored sound a fun, V-shaped tuning with an emphasis on low-end rumble and aggressive treble. But from the moment I pressed play, it became clear that Kiwi Ears had taken a completely different approach.

Instead of boosting the bass to overwhelming levels or pushing the treble into sharp, overly energetic territory, the Aether leans toward a neutral, refined, and almost reference-like tuning. It delivers a highly accurate representation of the recording, staying faithful to the source without artificial coloration or gimmicks. However, it doesnt fall into the trap of being sterile or lifeless. Instead, the Aether manages to strike a balance between technical precision and engaging musicality, making this a versatile set.

• Kiwi Ears Aether IEMs
• Stock cable
• 8 pairs of ear tips
• Carrying case
• Warranty card



Build Quality & Comfort
Despite housing a large 15.3mm planar driver, the Aether manages to stay remarkably ergonomic, lightweight and a little thick thats to be expected since this houses a big 15.3 planar driver. The smooth, contoured resin shell feels natural in the ear, offering a snug yet comfortable fit without any awkward pressure points. The medium-length nozzles strike a good balance, ensuring a secure seal without digging too deep into the ear canal.

One of the more interesting design choices is the enhanced ventilation system, which i dont see a lot on some of my planar IEMs. I noticed three vent holes near the connector and one additional vent near the base of the nozzle. These vents serve a crucial role in pressure regulation, preventing the dreaded "vacuum effect" that can cause discomfort over long listening sessions also this vent holes can also contributes to the Aether’s wide, spacious soundstage, giving it an almost open-back-like presentation. It’s a thoughtful engineering touch that enhances both comfort and acoustic performance.

I particularly love the faceplate design, it’s a mix of classy and playful without being over-the-top. The silver and black base gives it a sleek, modern look, while the green and purple flakes add just the right amount of flair, almost like a galaxy shimmering under the light. The embossed silver Kiwi Ears logo ties it all together, making the design feel premium yet fun. It’s the kind of faceplate that catches your eye but doesn’t scream for attention.

Sound Performance:
The Aether embraces a neutral, reference-like tuning, prioritizing accuracy and precision in how it reproduces sound. This means it delivers what the source demands nothing more, nothing less allowing it to adapt seamlessly to any genre. Whether it’s the deep, pulsating bass of hip-hop and techno, the soulful warmth of vocal jazz, or the intricate layering of an orchestral performance, the Aether handles it all with finesse.

But dont mistake its neutrality for dullness, this is not some lifeless, clinical tuning Instead, the Aether strikes a fine balance, offering a natural and engaging presentation that feels dynamic yet controlled. It’s a chameleon of an IEM, effortlessly shifting to match the mood and energy of the music, making it one of the most versatile tunings I’ve encountered. whether you are a critical listener dissecting every nuance or someone like me who simply wants to enjoy music in its purest form, the Aether delivers without imposing its own character on the sound.

Bass:
With a planar driver this large, you might expect an overwhelming low end, but Kiwi Ears has taken a more measured, refined approach prioritizing control and precision over raw power. The sub-bass reaches deep, offering a satisfying rumble that feels layered and textured, rather than just a uniform thump. It’s present when the track calls for it but never overbearing or bloated. Meanwhile, the mid-bass stays tight and neutral, delivering a clean, punchy impact without bleeding into the mids. This balance allows bass guitars, kick drums, and electronic beats to sound fast, articulate, and well-separated, rather than muddy or bloomy. The Aether’s bass is not the kind that rattles your skull i think no planar driver can do that. Instead, it offers clarity, speed, and natural decay, making it an excellent choice for those who appreciate a well-structured and accurate low end rather than exaggerated booms. Whether you’re listening to bass-heavy EDM, jazz, orchestral music, or classic rock, the Aether delivers a satisfying yet disciplined performance, ensuring every note is clean, tight, and true to the recording.

Midrange:
The midrange is one of Aether’s biggest strengths. It’s neutral, transparent, and highly resolving, staying true to the recording without unnecessary warmth or forwardness. Vocals, both male and female, sound realistic and well-articulated, with just the right amount of weight and body. Instruments like pianos, guitars, and strings benefit from the planar driver’s natural timbre and excellent and energetic transient response, making every note sound lifelike and nuanced. Unlike some planars that can sound overly analytical, the Aether manages to remain engaging and musical without sacrificing technicality.

Treble:
Treble tuning can make or break an IEM, and Kiwi Ears has struck an impressive balance with the Aether. Right away, I noticed that it avoids the common pitfalls of planar treble, where some models can sound either too sharp or unnaturally metallic. Instead, the Aether delivers an airy, well-extended top end that manages to be both detailed and smooth, making for an engaging yet fatigue-free listening experience.

Cymbals, hi-hats, and string overtones retain their natural shimmer and decay, without sounding brittle or exaggerated. There’s a delicate sparkle that adds energy and excitement to the presentation, yet it never strays into harshness or sibilance. The treble peak is tastefully done, providing just enough brightness to enhance clarity while keeping things comfortable for extended sessions.

What stands out is the effortless resolution, the Aether is capable of retrieving micro-details without sounding analytical or clinical. Subtle textures, like the breathiness of a flute or the fine nuances of a violin, come through clearly and naturally, lending a sense of realism and refinement to the sound. Even on less-than-perfect recordings, the treble remains forgiving yet articulate, making the Aether just as enjoyable for casual listening as it is for critical monitoring.

This is treble done right, airy, spacious, and detailed, without stepping into harsh or fatiguing territory. It complements the overall tuning beautifully, ensuring that every note feels lively, yet controlled and balanced.

Soundstage & Imaging:
A big planar driver with lots of vent holes equals to an expansive soundstage, which feels more like an open-back headphone than a traditional IEM. This is largely thanks to its vented chamber design, which allows for better airflow and a more spacious presentation.
Imaging is precise and three-dimensional, making it easy to locate instruments and vocals within the mix. This makes the Aether not just great for music but also for gaming, Movies and even professional audio work, where accurate spatial representation is crucial.

I decided to compare the MP145 with the Aether because the MP145 is the planar IEM I've used the most over the past two years. Comparing the Aether to all of my planar IEMs would take a lot more time and effort, but I did take some comparative measurements with a few of them for reference.

Aether vs. Simgot ET142

Aether vs. FiiO FP3

Aether vs. ARTTI T10

Aether vs. Kefine Klanar

Aether vs. Hidizs MP145

Kiwi Ears Aether vs. Hidizs MP145:
For this comparison i use Divinus Velvet eartips on both IEMs and FiiO JM21 DAP.

Tonality & Tuning
The Kiwi Ears Aether takes a more balanced and natural approach. It aims for neutrality with a slight musical warmth, keeping everything in check. The bass is present but never overpowering, mids are clear and expressive, and the treble is extended yet controlled, avoiding unnecessary peaks or harshness. It’s a well-rounded and mature tuning that suits a wide range of genres.

On the other hand, the Hidizs MP145 leans into a more V-shaped tuning with a focus on deep, powerful bass and a lively treble response. It has a more pronounced subbass presence, adding rumble and impact that bass lovers will appreciate. The treble, however, is sharper and airier, which can make details pop but also introduces some brightness that might not be for everyone. The mids are lush, warm but slightly recessed compared to the Aether, making vocals and instruments sit further back in the mix.

Bass
• Kiwi Ears Aether: The bass is tight, controlled, and well-textured. It doesn’t aim for a heavy impact but instead focuses on accuracy and cleanliness. Midbass is well-defined, adding warmth without bloat, and subbass is present but not dominant. It’s the kind of bass that integrates seamlessly into the mix.
• Hidizs MP145: The MP145 packs more bass quantity, particularly in the subbass region, making it deeper, darker and more powerful than the Aether. While it has good texture, it leans more toward a fun, dynamic bass rather than a neutral one. It can be a bit overwhelming for those who prefer a more balanced low end.

Mids
• Kiwi Ears Aether: clarity, natural timbre, and excellent balance. Vocals—both male and female—sound forward, engaging, and lifelike. Instruments have a good sense of weight and presence without feeling overly colored.
• Hidizs MP145: The MP145’s mids are more recessed due to its V-shaped tuning. Male vocals and lower mids feel a bit pushed back, while upper mids have a brighter, more energetic presentation. This makes female vocals stand out more but can sometimes make them sound slightly sharp, especially with brighter recordings.

Treble
• Kiwi Ears Aether: The treble is well-extended but smooth, providing plenty of detail without becoming fatiguing. It has a natural, airy presence, ensuring clarity without harshness. If you’re sensitive to treble peaks, the Aether is the safer choice.
• Hidizs MP145: The MP145 has a more pronounced treble, making it more energetic and airy than the Aether. This contributes to more energy and sparkle and more detailed presentation.

Technical Performance
• Soundstage: The Hidizs MP145 has a wide and more deeper expansive soundstage, likely due to its large 14.2mm driver and open-back-like venting. The Kiwi Ears Aether, while still wide, but not as deep as the mp145, but still gives instruments a more cohesive placement.
• Imaging & Separation: Both IEMs have solid imaging and separation, though the Aether’s more neutral tuning helps define each element with precision. The MP145, with its wider stage and sharper treble, can make details pop more, but it’s also more spread out, which may reduce pinpoint accuracy.
• Detail Retrieval: The MP145 extracts more microdetails, thanks to its brighter treble and more analytical tuning. The Aether, however, maintains excellent resolution while keeping things more natural and non-fatiguing.

Comfort & Build
• Kiwi Ears Aether: Features a lighter, more ergonomic shell, making it comfortable for long listening sessions. The smaller, more contoured design should fit a wider range of ears.
• Hidizs MP145: With its large metal shell and vented design, the MP145 can feel a bit bulky and protruding in the ears. While the fit is secure on my ears, people with smaller ears may struggle with its size.

Both IEMs showcase the strengths of planar drivers but cater to different preferences. The Kiwi Ears Aether is the better choice for those who value balance, natural tonality, and immersive mids. It’s an IEM that stays true to the music without unnecessary coloration. Meanwhile, the Hidizs MP145 delivers a more energetic, bass-driven experience, making it a great pick for those who enjoy a lively, engaging sound with deep lows and airy highs. At the end of the day, it all comes down to your personal taste, whether you seek natural precision or dynamic excitement, both IEMs offer compelling takes on planar technology.

Final Thoughts: A Planar IEM That Prioritizes Balance and Musicality
The Kiwi Ears Aether takes a different approach to planar IEM tuning, opting for balance, natural tonality, and precision rather than chasing extremes. While many planar IEMs lean toward exaggerated bass impact or hyper-detailed treble, the Aether refines the formula with a more cohesive and immersive presentation.

It delivers clean, well-textured bass, ensuring a solid foundation. The mids are transparent and naturally expressive, allowing vocals and instruments to shine with clarity and nuance. Meanwhile, the treble extends beautifully, offering detail and airiness without straying into harshness. The result is a sound that feels spacious, accurate, and effortlessly engaging, supported by a wide, well-defined soundstage.

While the Aether may not be the go-to choice for bassheads craving seismic rumbles or treble enthusiasts seeking an ultra-bright presentation, it excels at delivering a true-to-source, refined listening experience. For those who appreciate precision, realism, and a well-balanced tonality, the Kiwi Ears Aether stands out as an easy recommendation a proof to how neutrality, when executed well, can be anything but boring.

It’s amusing how the gap between mid-tier and budget DAPs is shrinking faster than my self-control during an online audio gear sale These days, the real distinction seems to boil down to build quality and materials because, in terms of performance, specs, and features, budget-friendly options are creeping dangerously close to their pricier rivals. In fact, they’re almost on par and some budget DAPs even outshine their pricier counterparts, making you wonder what exactly you’re paying extra for in the mid-tier range.

And that brings us to the FiiO JM21—a sleek, ultra-thin digital audio player that packs a surprising amount of premium features without the wallet-crushing price tag. On paper, it looks like a serious contender, boasting impressive hardware and a refined design that could easily pass for something much more expensive. But does it truly deliver the high-end experience it teases, or is it just another budget DAP with fancy marketing? On paper, it looks like a strong contender, Let’s take a closer look.

Whats in the box? here is a quick unboxing video of FiiO JM21:

Design & Build: Slim, Stylish, and Built for Convenience.
One of the FiiO JM21’s biggest selling points is its ultra-slim and lightweight design. At just 13mm thick and weighing only 156 grams, it’s one of the thinnest and lightest high-resolution digital audio players on the market today. If you're like me—someone who loves audiophile-grade sound on the go but gets battery anxiety when using a phone and dongle setup—this sleek little powerhouse is a breath of fresh air. It’s effortless to carry, slipping into a pocket or bag without the bulk of many high-end DAPs.
But portability isn’t the only thing FiiO nailed here—the design and aesthetics are just as impressive. The sleek aluminum and plastic frame strikes a great balance between durability and refinement, giving it a modern, polished look.

I just wish there were more color options to choose from—not necessarily for the JM21 itself, but at least for the case. While I appreciate the blue leather case for being a refreshing change from the usual black or brown, it does come with a downside: it’s prone to stains. The back and flap tend to pick up dirt easily, and over time, the color darkens, which can make it look worn out faster than expected.

Front and center is a 4.7-inch HD screen. While that might seem small compared to some flagship DAPs with sprawling displays, it’s sharper and more vibrant than my pricier Hiby R6 III—a pleasant surprise. The size is just right, making it easy to navigate music libraries, streaming apps, and system settings without feeling cramped.

One thing I noticed is that the screen sits slightly raised above the edges of the device. While this gives the JM21 a sleek, modern look, it also makes the display more vulnerable to damage if dropped, even from a short distance. Since the glass isn’t recessed or surrounded by a protective bezel, there’s a higher chance of it making direct contact with the ground if an accident happens.

This is where the leather case becomes more than just a stylish accessory—it’s practically a necessity. With the case on, the edges are fully covered and reinforced, offering much better protection against bumps and drops. If you’re planning to carry the JM21 around daily, especially in a bag or pocket, using the case is a smart move to keep the screen safe and prevent unnecessary wear and tear.



The touch response is smooth with no noticeable lag, and even in bright lighting, the display remains clear and legible.



One of the things I also appreciate about the FiiO JM21 is its incredibly thin and lightweight build. As someone who often stacks DAPs with external DACs and amps, I know how quickly a setup can become bulky and cumbersome. But the JM21’s slim profile makes a huge difference—it reduces the overall footprint of the stack and keeps the weight manageable, making it far more practical for somewhat portable use.








Under the Hood:
At the heart of the FiiO JM21 is a well-engineered combination of components designed to deliver clean, detailed, and dynamic sound. It features dual Cirrus Logic CS43198 DACs, a chipset which is widely praised for its transparent and natural sound reproduction, ensuring that the music is delivered with accuracy. Paired with dual SGM8262 OPAMPs, the JM21 maintains a fully balanced audio architecture, maximizing dymanic performance across the frequency range while keeping a zero to low distortion.

The JM21 is powered by a Snapdragon 680 octa-core processor, a welcome addition that guarantees a smooth, lag-free user experience for when you’re navigating through apps, adjusting settings, or streaming high-resolution audio, everything feels snappy and responsive—which is something not all Android-based DAPs in this price range (or even some higher-end ones) can claim.

FiiO has also implemented a segmented power system with shielded partitions to keep the analog and digital circuits isolated. This meticulous engineering helps minimize interference, ensuring that the JM21 delivers an uncolored, natural sound signature with a clean black background, free from unwanted noise or distortion.

Sound Performance:
This budget dap delivers impressive sonic muscle in a compact package. With an 700mW per channel through its 4.4mm balanced output, this little DAP has no trouble driving everything from sensitive IEMs to moderately demanding full-sized headphones. The inclusion of three gain levels makes it even more adaptable, allowing users to fine-tune the output for optimal performance with different gear.

The iems i use for this review are the Simgot et142, kiwi ears Airoso, Fiio FP3 and Tin Hifi T7 with not EQ and filters applied.

Bass: Deep, Controlled, and Impactful
The JM21 delivers tight, well-controlled bass with excellent extension into the subbass regions. There’s no excessive bloom or muddiness, keeping the low end precise and well-defined. The subbass digs deep when called upon, adding a satisfying rumble that enhances genres like EDM and hip-hop without overpowering the mix. Meanwhile, the midbass carries a solid punch, adding just the right amount of weight and warmth without bleeding into the mids. Whether you prefer articulate bass lines or a more visceral impact, the JM21 strikes a balance that remains engaging and musical.

Mids: Clean, Lush, and Natural
Vocals and instruments shine with clarity, warmth, and an organic tonality. The JM21 presents the midrange with a natural timbre, ensuring that both male and female vocals sound full-bodied and well-textured without any artificial coloration. Acoustic instruments, from pianos to guitars and strings, retain their natural resonance, making this DAP a fantastic choice for vocal-heavy tracks, jazz, and acoustic performances. There’s a good balance between warmth and detail, making sure the mids remain engaging without sounding too analytical or clinical.

Treble: Airy, Crisp, and Non-Fatiguing
The treble is clean, detailed, and well-extended without ever veering into harshness or sibilance. There’s plenty of air and sparkle, adding a sense of openness and liveliness to the sound without becoming fatiguing. High frequencies are rendered with great resolution, ensuring that cymbals shimmer naturally, strings maintain their bite, and micro-details in recordings remain intact. Whether you enjoy the crispness of a well-recorded jazz cymbal or the intricate layering of an orchestral piece, the JM21 delivers treble that is both revealing and smooth.

Soundstage & Imaging: Spacious and Precise
Despite its compact size, the JM21 impresses with a spacious and well-layered soundstage. It creates a realistic sense of depth and width, making music feel more immersive and natural. Imaging is precise and well-defined, allowing instruments to be easily pinpointed in the mix. This makes it particularly enjoyable for complex arrangements, live recordings, and well-produced tracks that rely on spatial cues like tracks from Amber Rubarth's Session from the 17th ward album.



Comparison to my R6 III:
Compared to my Hiby R6 III, which has been my daily driver for the past two years, the FiiO JM21 takes a different approach to sound tuning. The R6 III leans towards a neutral-warm tonality, adding a slight richness and warmth to the overall presentation, making it particularly enjoyable for long listening sessions with a more relaxed, organic character.

In contrast, the JM21 prioritizes transparency and neutrality, offering a cleaner, more uncolored sound that stays true to the recording. It doesn’t inject any noticeable warmth or coloration, making it a great choice for those who prefer their music as it was intended to be heard. This makes it particularly revealing when paired with IEMs or headphones that already have their own unique tuning, allowing their inherent characteristics to shine without interference.

From a technical standpoint, the JM21 holds its own with good resolution, clarity, and separation, making it easy to pick out individual instruments and subtle details within a track. Imaging is well-defined, and while it doesn’t create an artificially wide or exaggerated soundstage, it delivers an ample sense of space that feels natural and immersive. Compared to the R6 III, which leans slightly more intimate in its presentation, the JM21 presents a more open and spacious feel, allowing instruments and vocals to breathe a little more.

Overall, if you enjoy a warmer, slightly more relaxed tuning, the R6 III remains a fantastic choice. But if you prefer a more neutral, transparent sound with a focus on clarity and technicalities, the JM21 is a solid step in that direction. It’s a DAP that lets your gear do the talking while ensuring a refined and engaging listening experience.

Software & Features:
The FiiO JM21 runs on Android 13, which means you’re getting a full-fledged, open ecosystem rather than a locked-down, proprietary interface. This makes a world of difference for users who want flexibility—you're not stuck with just one default music player. So if you prefer Apple Music, Tidal, Qobuz, Spotify, or even something more niche like Poweramp or Neutron, you have the freedom to install and use whatever suits your listening style.

In the settings menu, there's a Work Mode option where you can choose from five different modes, each tailored for a specific use case:

• Android Mode (Default) – This is the standard mode that lets you install apps for streaming music, browsing online, and more, just like any Android device.

• Pure Music Mode – Designed for the purists, this mode locks the device into the FiiO Music Player for offline playback. Some users claim it sounds cleaner than Android Mode since it disables Wi-Fi and Bluetooth, potentially eliminating any signal noise. Personally, I don’t notice a difference, but if you believe in the magic of minimal interference, this might be worth trying.

• USB DAC Mode – This mode turns the JM21 into a transport device, allowing you to connect an external USB DAC or dongle for music processing and amplification. Ideal if you want to bypass the built-in DAC and use something more powerful.

• Bluetooth Receiver Mode – Enables the JM21 to function as a Bluetooth DAC/amp, letting it receive audio from another Bluetooth source, like your phone or laptop.

• AirPlay Mode – Allows the JM21 to connect to any AirPlay-enabled device for seamless wireless audio streaming.

One of the JM21 features is FiiO’s Digital Audio Purification System (DAPS). If you’ve used Android-based DAPs before, you probably know about SRC (sample rate conversion) issues, where Android forces all audio through a resampling process that can degrade quality. DAPS ensures that the JM21 bypasses this entirely, meaning whether you're streaming hi-res tracks or playing local lossless files, you’re getting them in their purest, unaltered form.

On the connectivity front, the JM21 also offers two-way Hi-Definition Bluetooth with support for LDAC, aptX HD, and AAC, ensuring high-quality wireless audio whether you’re sending or receiving a signal. This makes it just as capable for wireless headphones and TWS earbuds as it is for high-end wired setups. If you prefer a traditional wired connection, you have SPDIF, USB, and Line-Out (LO) outputs, giving you plenty of options to integrate it into your existing gear—whether it's a dedicated DAC/amp setup, an external speaker system, or even a car audio rig.
In short, the JM21 isn’t just another Android-based DAP—it’s a versatile, audiophile-friendly device that blends software freedom with robust hardware features.

Verdict: A High-Value, Feature-Packed DAP
The FiiO JM21 challenges expectations of what an ultra-thin DAP can be, packing premium sound quality, impressive power output, and a smooth, full-fledged Android experience into a sleek, pocket-friendly design. It goes toe-to-toe with pricier competitors while maintaining an accessible price point, making it an attractive option for a wide range of listeners.

Who is it for?

• Portable audiophiles who want top-notch sound without the bulk of a full-sized player. The JM21’s slim, lightweight design makes it an ideal travel companion.
• Users who stream frequently, thanks to its snappy UI, full Google Play Store access, and strong app compatibility. Whether you rely on Tidal, Qobuz, Apple Music, or Spotify, the JM21 handles it all effortlessly.
• IEM and headphone enthusiasts who appreciate versatility. With three gain levels and a robust output stage, it can power everything from sensitive IEMs to higher-impedance headphones with ease.

Who might want to pass?

• Users who need marathon battery life—at 10–12.5 hours, battery life is solid but not groundbreaking, especially compared to some larger players with bigger batteries.

At the end of the day, the FiiO JM21 stands out as one of the best bang-for-your-buck DAPs on the market today. It delivers refined sound, solid power output, excellent build quality, and a full-fledged Android experience—all wrapped up in an ultra-thin, highly portable design.

For those of us always on the hunt for a budget-friendly yet high-value DAP, the JM21 hits a sweet spot between power, portability, and premium features. It proves that you don’t need to break the bank to get a well-built, great-sounding player with modern conveniences like full app support, high-resolution playback, and versatile connectivity. If you're looking for a DAP that’s lightweight yet delivers an uncompromised listening experience, the JM21 stands alone in its price range—there’s simply nothing else on the market right now that matches its performance for the price.

I'll be honest—reviewing the SIMGOT ET142 was an uphill battle, but not for the usual reasons. As a reviewer, it's my job to find both strengths and weaknesses, to offer a fair and balanced perspective. But with the ET142, I genuinely struggled to find anything to critique.

Over the past few years, Chi-Fi has reached new heights in craftsmanship and innovation. Many modern IEMs not only compete with but often surpass mainstream giants in both sound and build quality. SIMGOT, in particular, has been on an impressive streak. From the EW100 and EW300 to the EA500, EA500LM, and now the ET142, every release feels meticulously crafted and refined.

If there's one thing I've come to associate with SIMGOT, it's their signature clarity, refined treble, and exceptional resolution. Even when they released the warmer-leaning EW300 last year, it still maintained that energetic, lively treble. The ET142, however, takes things to another level—it’s balanced, immersive, and effortlessly natural, delivering one of the most compelling listening experiences I’ve had in a long time.

Note:
I heard that Simgot initially released an early version of the ET142 last year to a select group of evaluators. From what I’ve gathered, the original prototype leaned heavily towards an analytical sound—perhaps a bit too clinical for some tastes. Simgot took that feedback to heart and went back to the drawing board, fine-tuning the ET142 to strike a better balance. The final version still retains that impressive technical prowess, but now it also brings a more organic, musical character to the table.

Whats in the box? heres a quick unboxing video of the Simgot ET142.

Build & Design:
The ET142 might be a finger print magnet like the ea500 but its still a work of aesthetic and engineering brilliance. The CNC-machined alloy shell feels premium, durable, offering an ergonomic fit that remains comfortable even during extended listening sessions.
My nozzled of choice is the “Blazed Titanium” nozzles. These nozzles are crafted through a high-temperature flame-bluing process, creating unique, unpredictable hues ranging from blue and purple to red and yellow. Each set is one-of-a-kind, reflecting the handmade nature of this craft. i have titanium bike parts like this they call it Oil Slick because of the rainbow hues it make when a light hits the surface just like how an oil slick look on water.

Interchangeable Nozzles for Custom Tuning
One of the standout features of this IEM is its included tuning kit consist of 4 nozzles and some tuning foam, allowing listeners to fine-tune the sound to match their preferences. Each nozzle material and design subtly alters the frequency response, making it easy to switch between different sound signatures depending on your mood or genre of choice.

• Blazed Titanium (Transparent Silicone Ring): A warm yet balanced tuning, making it a great all-rounder for general listening. It provides a natural, musical presentation with a touch of warmth, making vocals and instruments feel more organic. This, along with the Red Ring nozzle, is my personal pick for everyday use.

• Gold-Plated Copper (Yellow Silicone Ring): This nozzle emphasizes airy, extended treble, bringing out brilliant detail and spaciousness in the highs. It’s perfect for classical, acoustic, and instrumental music, where the extra air and clarity help strings, pianos, and orchestral arrangements shine, this one i consider as the closest to the Simgot house sound.

• Stainless Steel (Red-Circle Short Tube): This nozzle introduces a slight dip in the upper midrange and lower treble, shifting the focus toward a cleaner, more powerful bass response. It creates a fun, energetic, and musical tuning, ideal for those who enjoy a strong low-end presence.

• Stainless Steel (Black-Circle Short Tube): A smoother, more dynamic tuning that strikes a natural balance across the frequency range. It offers a relaxed yet engaging presentation, making it a great choice for long listening sessions or for those who prefer a non-fatiguing yet detailed sound signature. This and the Titaniun nozzle are very similar sounding.

Sound Performance:
The ET142 isn’t just technically proficient, it’s musically engaging, striking an ideal balance between resolution, dynamics, and natural tonality.

Bass:
The ET142's bass is a masterclass in balance, power, and control. The subbass digs deep, offering a rich, authoritative presence that delivers a satisfying, well-textured rumble. It reaches into the lower depths with confidence, adding a sense of weight and depth without ever feeling bloated or excessive, the subbass maintains a refined yet immersive quality.

The midbass is punchy and well-defined, striking a fine balance between impact and restraint. It provides a solid foundation for rhythm-heavy tracks, injecting energy and presence without bleeding into the mids. The attack is snappy and precise, while the fast decay keeps things tight, ensuring that basslines remain clean and articulate rather than muddy or sluggish.
What stands out about the ET142’s low end is its sense of discipline it’s powerful yet controlled, allowing intricate bass textures to shine through. This makes it just as enjoyable for bass guitar grooves and jazz upright bass as it is for electronic beats and cinematic soundscapes. If youre a bass lover and who appreciates clarity and separation, the ET142 delivers an engaging, well-tuned bass experience that enhances the music without overwhelming it.

Midrange:
SIMGOT has truly nailed the midrange tuning on this set, striking a delicate balance between warmth, clarity, and realism, something that’s not always easy to achieve, especially with a planar driver. Male and female vocals sound organic and lifelike, free from the artificial coloration or overly thin presentation that some planar drivers tend to introduce. There’s a natural weight to the lower mids, giving male vocals a rich, full-bodied presence, while female vocals shine with clarity and expressiveness, never veering into sibilance or harshness.
Instrument separation is another highlight. Each element in the mix feels distinct yet cohesive, allowing guitars, pianos, and strings to breathe naturally within the soundstage. The layering is excellent, giving the midrange an almost three-dimensional feel where details emerge effortlessly without being forced.
The upper mids are crisp, well-detailed, and airy, providing an engaging sense of clarity without ever becoming overly forward or harsh. SIMGOT has done a fantastic job of taming any potential planar timbre issues, as I couldn’t detect any of that unnatural metallic sheen that sometimes plagues planar IEMs. Both vocals and acoustic instruments come across as organic, nuanced, and true to life, making the midrange one of the strongest aspects of this tuning.

Treble:
SIMGOT has built a reputation for exceptional treble tuning, and the ET142 continues that legacy with finesse. The multi-layer PZT driver does a remarkable job of handling both the high and ultra-high frequencies, delivering an experience that feels detailed, airy, and effortlessly extended. Treble notes shimmer with clarity and precision, allowing micro-details to shine through without ever becoming fatiguing or overly sharp.

What makes the treble stand out is its balance between smoothness and energy. It has just the right amount of brightness to bring out the sparkle in cymbals, the delicate bite of a violin, or the airiness in vocal harmonics all without crossing into harsh territory. Sibilance is kept in check, and there’s a natural decay to high-frequency elements, ensuring that instruments like flutes and chimes retain their organic timbre rather than sounding artificially sharp.

Another impressive aspect is the treble’s sense of layering and depth. There’s an openness to the presentation that adds dimension to the soundstage ( a known Simgot trait to almost all simgot iems) makes the highs feel well-separated and spacious rather than compressed. This extension into the ultra-high frequencies contributes to a sense of air and refinement, giving music a lifelike, resolving character that makes listening a pleasure for both detail lovers and those who prefer a fatigue-free experience.

With its well-controlled sparkle, excellent micro-resolution, and smooth yet energetic presentation, the ET142’s treble is ver well presented, enhancing every genre.

Soundstage & Imaging:
The soundstage is expansive, providing an immersive, out-of-head experience. Imaging is pinpoint-accurate, making it easy to distinguish instruments and spatial cues. While the stage isn’t the deepest I’ve heard, the lateral width and precise separation create an incredibly immersive listening environment.

Resolution & Dynamics:
The ET142 delivers an exceptional level of resolution and dynamic expression, making it one of the most impressive sets I’ve heard from SIMGOT to date. From micro-detail retrieval to large-scale dynamic shifts, this IEM excels at bringing out the finest nuances in a recording while maintaining a natural and engaging presentation.

At the micro level, the ET142 picks up on the smallest details, the delicate decay of a cymbal as it fades into the background, the subtle breath between vocal phrases, or the nuanced pluck of a guitar string that resonates with depth and texture. Each note carries an intricate sense of realism, as if the recording space itself is coming to life. The precision in micro-dynamics makes every track feel immersive, revealing layers of sound that might go unnoticed on lesser IEMs.

On a macro scale, the ET142 handles dynamic swings with authority and finesse. Whether it’s the sudden impact of a drum hit, the swelling intensity of an orchestral crescendo, or the energetic rise and fall of a jazz ensemble, the ET142 delivers a satisfying sense of scale and impact without sounding compressed or congested. The balance between soft, intimate moments and powerful, room-filling passages is finely tuned, ensuring that music retains its natural ebb and flow.

What sets the ET142 apart is how effortlessly it presents resolution but at times it can feel clinical but not fatiguing. It doesn’t just dissect recordings—it enhances the listening experience by making every detail feel natural and emotionally engaging.

Flagship-Grade Cable: The LC7 – A Stock Cable Worth Talking About
If there were an award for the best stock cable, the LC7 would take the crown—no question. SIMGOT didn't hold back here; they included their $70 premium LC7 cable right in the box. And honestly? That’s a pretty big deal.

This 732-core Litz cable is a blend of high-purity oxygen-free copper (OFC) and silver-plated strands, designed to enhance resolution, dynamics, and transient response. It’s not just about looks—this construction improves conductivity, ensuring that your audio chain remains as clean and detailed as possible.

Like most upgrad cable this also has interchangeable 3.5mm and 4.4mm plugs, allowing you to switch between single-ended and balanced sources effortlessly. No need for extra adapters or third-party cables—it’s all here, right out of the box.

That said, it does have a bit of weight to it. Compared to some of my other cables, the LC7 feels noticeably thicker and more substantial, likely due to the higher strand count and thicker gauge silver-plated copper wiring. While it adds a sense of durability and premium feel, some might prefer a lighter cable for comfort. But if you’re after top-tier conductivity and sonic performance, this is a trade-off worth making.

Final Verdict: My New Benchmark for Planar Hybrids

With the ET142, SIMGOT has set a new standard for hybrid planar IEMs. It delivers an exceptionally well-balanced sound, combining deep, authoritative bass, lifelike mids, and refined treble, all wrapped in a premium, comfortable design.

If you’re looking for a high-resolution IEM that is both technically brilliant and musically engaging, the SIMGOT ET142 is an absolute must-audition. If you’re a critical listener or someone who simply wants pure, immersive enjoyment, this IEM is nothing short of a masterpiece.

I tried pairing the ET142 with a warmer analog sounding source and the pairing brought out another layer of richness and depth.

SIMGOT ET142 is a near-flawless execution of hybrid planar technology. It’s technical yet musical, detailed yet natural, and refined yet engaging.

this is an easy recommendation. SIMGOT continues to raise the bar, and the ET142 is undoubtedly one of their finest releases yet.

Kiwi Ears has steadily built a reputation for crafting IEMs that strike a thoughtful balance between musicality and technical performance. With the Airoso, they introduce a new take on their tuning philosophy—one that refines their approach while adding a dose of energy and excitement.

While the KE4 leaned towards a deep, immersive bass experience with a neutral and smooth presentation, the Airoso takes a different route. It aims for a livelier, more engaging sound, with a dynamic tuning and a treble presentation that stands out.

But does this shift in approach translate to a well-balanced and enjoyable listening experience, or does it come at the expense of refinement? Let’s take a closer look.

Whats in the box? heres a quick unbox video of the Airoso.



Unboxing & Accessories
Kiwi Ears has alway kept things simple with the packaging. Inside the box, you’ll find:
• 1x Kiwi Ears Airoso IEM
• 1x Detachable Cable (0.78mm 2-pin, 3.5mm termination)
• 8x Pairs of Eartips (various sizes and shapes)
• 1x Carrying Case
• 1x User Manual

The inclusion of eight pairs of eartips is a thoughtful touch, ensuring users can fine-tune the fit and sound. The detachable cable is solid but fairly standard and thin for my taste—I’d recommend upgrading to a higher-quality cable if you’re chasing that last bit of performance.

Build & Comfort
The Kiwi Ears Airoso boasts a sleek yet rugged design that blends aesthetics with functionality. Its shell appears to be crafted from solid black resin, offering a smooth, contoured fit that conforms effortlessly to the ear. The faceplate, in contrast, features a raw-finished brushed titanium surface, giving the Airoso an industrial, almost modern minimalist appeal. Despite its robust appearance, the IEM remains surprisingly lightweight, making it comfortable for extended listening sessions.

True to Kiwi Ears’ reputation, the ergonomics are spot-on—the fit feels secure yet pressure-free, ensuring a snug seal without discomfort. This makes the Airoso an excellent choice for both casual and prolonged use. The flat 2-pin connector is a smart inclusion, offering durability and a secure connection while reducing strain on the socket over time.

The build quality is outstanding, striking a fine balance between durability and elegance. Every detail, from the choice of materials to the smooth finishing, reflects a premium standard. I also can’t help but appreciate Kiwi Ears’ industrial-inspired aesthetic, it’s bold, raw, modern and refreshingly subdued.

Sound Quality
Now, let’s get to what really matters—the Airoso’s sound signature. This IEM stands out with an engaging, dynamic, and refined presentation, striking a balance between depth, clarity, and energy. It delivers a deep, authoritative bass, articulate mids, and one of the best treble tunings I’ve heard from Kiwi Ears.

I think the reason why Kiwi Ears named this set The Airoso because it likely hints at its airy treble, which adds an expansive and open feel to the sound. The mids and highs almost give off an open-back-like presentation, creating a spacious and natural atmosphere, while the bass remains tight, powerful, and controlled, reminiscent of a closed-back design. This combination makes for a unique and captivating listening experience, blending openness with impact in a way that feels both immersive and well-balanced.


Bass – Deep, Controlled, and Engaging
The Airoso retains the deep, authoritative bass that made the KE4 stand out, but it’s more controlled and refined. There’s less bloat, more texture, and a faster decay, making the low end feel tight yet very powerful. Subbass digs deep with excellent rumble, while the midbass delivers punch and warmth without overpowering the rest of the sound.
Bass lovers will still find plenty to enjoy, but what sets the Airoso apart is how well it integrates with the mids and treble, it never overshadows the rest of the spectrum.

Midrange – Balanced and Natural
The mids strike a balance between clarity and musicality. Instruments sound natural and well-defined, with just the right amount of weight.

Male vocals sound rich, textured, and grounded, carrying a natural warmth that makes them feel lifelike. Female vocals, on the other hand, are expressive and lively, with a crisp articulation that allows emotions to come through effortlessly.

The upper midrange is energetic yet refined and smooth, giving vocals and instruments a sense of presence without veering into sharpness or sibilance.

Treble – The Star of the Show, The Air in Air-oso
This is where the Airoso sets itself apart. The treble is layered, detailed, and beautifully refined—it’s airy, full of micro-detail, and incredibly well-separated. It’s like hearing three different kinds of treble working in harmony, each adding something unique:
• Lower Treble: Clear and energetic, adding definition without harshness.
• Mid Treble: Detailed and transparent, bringing out subtle nuances in instruments.
• Upper Treble: Airy and expansive, extending beautifully without becoming fatiguing.
Despite this wealth of treble information, the Airoso never sounds overly bright or sharp. Kiwi Ears has somehow managed to extract exceptional detail while maintaining a smooth, natural tonality. It’s one of the best treble tunings I’ve heard from the brand, refined, open, and endlessly enjoyable.


Soundstage & Imaging – Expansive and Holographic
The Kiwi Ears Airoso scales noticeably with power, revealing more depth and refinement when paired with a capable source. With proper amplification, the soundstage expands beautifully, offering an impressively wide and holographic presentation. There’s a genuine sense of space, allowing instruments to feel naturally positioned rather than crammed together.

One of the standout aspects is the precise imaging, each element in a track is distinct and well-placed, making it easy to pick apart layers of a mix. This level of separation enhances the overall immersion, pulling you into the music rather than just presenting it to you.

What makes the Airoso even more compelling is its ability to balance technical precision with musicality. Unlike some analytical IEMs that can feel clinical or fatiguing over time, the Airoso retains a smooth, engaging character, ensuring that critical listening doesn’t come at the expense of enjoyment. It’s a rare blend of detail, depth, and emotion.

Drivability & Pairing
With an impedance of 15Ω and a sensitivity of 105dB, the Kiwi Ears Airoso isn’t particularly demanding in terms of power, it’ll run just fine off most portable sources, including smartphones, dongle DACs, and entry-level DAPs. However, to truly experience what it’s capable of, it benefits significantly from a higher-quality source.

Feeding the Airoso with a more powerful DAC or amplifier doesn’t just increase volume—it enhances dynamics, expands the soundstage, and refines imaging, creating a more holographic and immersive experience. The bass gains better control and texture, mids become more expressive, and treble takes on a more refined, airy quality.

For the best pairing, I’d recommend a neutral or slightly warm source—something that complements its tuning without over emphasizing any particular frequency. The Hiby R6 III DAP is an excellent match, providing clean power with a touch of warmth. If you prefer a desktop setup, the FiiO K11 R2R DAC/amp would be another fantastic option, adding a bit of analog smoothness while preserving detail and resolution. With the right setup, the Airoso truly comes even more alive, offering a sound that feels both expansive and intimate at the same time.

Conclusion – A Refined Yet Fun Hybrid IEM

The Kiwi Ears Airoso is an exceptionally well-tuned hybrid IEM that delivers deep, controlled bass, natural mids, and some of the best treble tuning in its class. It takes everything great about the KE4 and refines it, adding better control, enhanced layering, and an airier, more spacious presentation.
• Bass lovers will appreciate the depth and punch without bloat.
• Treble enthusiasts will love the detail, separation, and airiness.
• Those looking for an immersive, high-fidelity experience will be impressed by its holographic staging.
For those who want a fun yet refined IEM that scales beautifully with better gear, the Airoso is a fantastic choice. It’s clear that Kiwi Ears poured a lot of thought into its tuning, and the result is an IEM that doesn’t just sound good—it feels special.
If they named it Airoso because of how airy the treble is... well, that makes perfect sense.

It’s been nearly two decades since I last played a vinyl record, and I have to admit—going through the ritual again was something else. The moment I pulled out a record, carefully holding it by the edges with my index finger and thumb, placed it on the platter, and brushed off any dust before lowering the tonearm, I felt like I had stepped back in time. It was as if my hands never forgot. The muscle memory kicked in instantly, and a wave of nostalgia hit me—hard.

I never planned on getting back into vinyl, nor did I expect to. But when FiiO offered me the chance to review the TT13, I thought, why not? There’s something deeply special about physically owning your music—something I had almost forgotten after years of digital playback and streaming through Tidal. It’s one thing to have instant access to millions of songs at your fingertips, but it’s a completely different experience to hold your music, to interact with it in a tangible way.
Luckily, I still had some of my old records, though many were tucked away in storage. I also decided to buy a couple of new ones, and to my surprise, vinyl has gotten expensive! In today’s world of convenience, where streaming makes everything so effortless, stepping back into vinyl can feel like an expensive commitment especially if you don’t already have a collection. It’s not the most practical or cost-effective way to listen to music, but for me, that’s precisely what makes it special.

Playing vinyl isn’t just about the sound it’s about the process. It forces you to slow down. When you put on a record, it means you have the time to sit down, pull out an album, clean it, and play it. There’s no skipping around, no instant shuffle—just you and the music, uninterrupted. And that, to me, is incredibly therapeutic. It’s not just nostalgia—it’s a way to truly engage with music in a way that digital formats simply can’t replicate.

But does it truly deliver an authentic HiFi experience? Let’s find out.

Unboxing and First Impressions

This is, without a doubt, the biggest and heaviest review unit I’ve ever received. Most of the gear I usually review falls into the portable category—IEMs, headphones, dongle DACs, and desktop amps. But the FiiO TT13? This thing is on a whole different level.

Right out of the box, the TT13 makes a strong first impression. It has a reassuring heft to it, tipping the scales at nearly 4kg, which immediately tells you that stability was a key consideration in its design. The aluminum alloy chassis not only gives it a premium look but also plays a role in minimizing unwanted vibrations—something crucial for a turntable. The build quality feels rock solid, and it’s clear that FiiO put thought into both aesthetics and functionality.

The included accessories cover all the basics you need to get started: a custom infrared remote (a rare but welcome addition for a turntable), an RCA audio cable with grounding, a power adapter, and a 7-inch record adapter. The dust cover is another thoughtful touch, helping to keep both the stylus and your records free from dust accumulation.

The platter itself is made of cast aluminum, and it feels weighty and well-machined. It provides a solid foundation for playback, ensuring smooth and consistent rotation—something that’s vital for accurate speed and pitch stability. Every component feels purposefully designed, making it clear that FiiO didn’t just slap together a turntable for the sake of it; they put in the effort to make sure it delivers both in form and function.

Installing the platter in pretty straigh forward you just need to hook the pre-installed rubber on the motor spindle using the paper tab to hold the belt in place.



Features and Performance
One of the TT13’s most convenient features is its fully automatic tonearm—an absolute game-changer for me whos last turntable is fully manual and also for those new to turntables or anyone with less-than-steady hands. In my case, I even use a flashlight just to see the exact groove where I want to drop the stylus (hey, gotta make sure I hit the right spot, right?). But with the TT13, that’s not an issue. With just the press of a button, the tonearm gracefully lifts, moves to the record’s starting groove, and gently lowers itself to begin playback. No need to manually position the needle, reducing the risk of scratching your records or accidentally damaging the stylus.



Once the record reaches the end, the tonearm automatically returns to its resting position—so you don’t have to scramble to lift it before the endless loop of silence (or crackles) kicks in. But for those who like a bit more control, FiiO has thoughtfully included a manual option. Simply press the Up/Down button, and the tonearm will lift smoothly, allowing you to place it precisely where you want—whether it’s to replay your favorite track or jump to a specific section. Press the button again, and it lowers the stylus gently onto the vinyl. It’s a perfect blend of convenience and flexibility, catering to both casual listeners and those who enjoy a more hands-on approach.



To top it off, FiiO has included a repeat playback function, letting the TT13 continuously loop your record without interruption. Whether you’re setting the mood with background music or just want to get lost in an album without constantly flipping sides, this feature makes the experience all the more enjoyable.

Built-in Phono Preamp: Plug-and-Play Simplicity
One of the biggest headaches for newcomers to vinyl or even an enthusiasts setting up a new turntable is dealing with an external phono preamp. Many older turntables require one, adding to both cost and complexity. Fortunately, the FiiO TT13 eliminates that hassle with a high-quality built-in phono preamp that delivers an impressively strong 800mV signal at 1kHz—more than double what you’ll find in many competing models. This means you can connect the TT13 directly to powered speakers or an amplifier without needing additional hardware, making setup effortless while saving money.



The TT13 isn’t just about amplifying the signal—it’s about preserving the rich, warm character of analog sound with remarkable attention to detail. At the heart of its preamp section are two JRC5532 op-amps, arranged in a carefully tuned two-stage amplification circuit that ensures an optimal signal path. This thoughtful engineering results in a clean, noise-free output, faithfully capturing the depth, dynamics, and intricate details of your vinyl record


.
To further enhance audio fidelity, FiiO has incorporated an independent LDO power supply and high-quality electrolytic capacitors, effectively minimizing unwanted distortion and delivering a smooth, natural frequency response. However, for those who prefer using their own external phono preamp—myself included—FiiO has not added a bypass switch, which would have allowed you to disable the built-in amplification and run the TT13 purely as a line-level source.

One puzzling addition, though, is the balance knob located at the back. While balance adjustments can be useful in some setups, I can’t help but wonder why FiiO didn’t opt for a gain or volume control instead—especially since the TT13 already features a built-in preamp and line-out functionality. A volume or gain adjustment would have provided more flexibility, particularly for those pairing the TT13 with powered speakers or amps with fixed inputs.



Sound Quality: Faithful and Transparent Playback
When it comes to sound reproduction, the FiiO TT13 stands out for its accuracy and fidelity to the source material. Unlike many entry-level turntables that introduce excessive warmth, coloration, or a "vintage" graininess to the sound, the TT13 stays remarkably true to the mastering of the record.

While it still retains the organic, smooth nature of analog playback, it doesn’t artificially boost warmth or add a rolled-off treble, which some may associate with the stereotypical "analog" sound. Instead, the TT13 delivers a clean, transparent presentation that faithfully reflects the recording, mixing, and mastering choices made in the studio. This means that if a record was mastered with crisp highs and deep bass, the TT13 will reproduce it with clarity and precision—and if the recording has a more neutral or warm balance, that’s exactly what you’ll hear.

This level of accuracy makes the TT13 an excellent choice for audiophiles and music enthusiasts who want to experience their vinyl collection as intended by the artists and engineers, rather than relying on built-in coloration from the turntable itself. It also pairs well with external phono preamps and different speaker setups, allowing users to fine-tune their system’s overall sonic character to their preference.

Ultimately, the TT13’s sound signature is less about nostalgia and more about fidelity offering a balanced, true-to-source listening experience.



AptX Bluetooth: Wireless Done Right
I was not a fan of wireless audio but for those who appreciate the convenience of wireless streaming, the TT13’s Bluetooth-enabled version supports aptX, aptX HD, and aptX Low Latency no LDAC though. This Codecs ensures high-resolution audio transmission with minimal delay, making it one of the better Bluetooth vinyl solutions on the market. While purists may prefer a wired connection, it’s nice to have this option,



For the sake of this review i tested the wireless option of the TT13, (the breathing light of the Fiio logo indicates bluetooth connection status) well I never thought I’d find myself pairing a turntable with Bluetooth to listen to my records yet here we are! Honestly, I went into this with low expectations, but I was genuinely surprised by how good it sounded.




I tested it with the Fosi Audio MC331 tube amp driving my Sivga Anser, as well as the FiiO UTWS5 connected to the Hidizs MP143 planar IEM. Surprisingly, I actually found the Bluetooth setup with the UTWS5 to sound more dynamic, with a livelier presentation than I expected. Now, that got me thinking—if the TT13 supported LDAC, it could take things up another notch, bringing even more clarity and detail to wireless playback. That would be a game-changer for a feature I initially dismissed as just a convenience.



Stability Matters
Turntables are inherently sensitive to external vibrations, which can introduce unwanted resonance and distort playback quality. To combat this, the FiiO TT13 features a rigid aluminum alloy chassis paired with substantial rubberized feet, designed to absorb shocks and minimize structural resonance. This ensures that, even in environments with minor vibrations, playback remains steady and uninterrupted—as long as the turntable is positioned correctly.

However, placement is crucial. If you're using headphones or have your speakers on a separate platform, the TT13 will perform optimally with minimal interference. But in my case, I set it up between my bookshelf speakers and a tube amplifier, and at higher volumes, I started experiencing acoustic feedback or a bass loop. This happens when low-frequency vibrations from the speakers travel through the surface, get picked up by the turntable’s cartridge, and are amplified again through the speakers—creating an endless loop of bass resonance. To resolve this, I added anti-vibration feet to further isolate the TT13 from unwanted movement. If you have the space, an even better solution is to place your bookshelf speakers on a separate platform from the turntable. Proper isolation not only enhances playback clarity but also prevents that dreaded low-end muddiness caused by vibration interference.



Customizable Lighting: Aesthetics and Ambiance
One of my favorite features of the FiiO TT13—and something that truly makes it stand out from traditional turntables—is its built-in ambient lighting. This isn’t just a gimmick; it adds a unique, modern touch to the experience. Users can cycle through seven different colors or turn the lighting off entirely, depending on their preference. Personally, I love the spinning light effect around the platter—it instantly reminds me of the Pioneer CDJ turntables, giving it a sleek, fun vibe.



Beyond aesthetics, the illuminated FiiO logo serves a functional purpose as well—it doubles as a Bluetooth connection status indicator, subtly blending style with utility. Of course, the lighting doesn’t affect sound quality in any way, but it does add a level of personalization to your setup. I often match the TT13’s lights to my Neohippo VU meter, which also features customizable RGB lighting, creating a visually cohesive and stylish listening space. Small details like this make the TT13 feel more like a centerpiece rather than just another turntable.



Cartridge and Playback Performance
Equipped with the Audio-Technica AT3600LA cartridge, the TT13 ensures clean and balanced playback with solid tracking ability. While not a high-end cartridge, it performs well in this price range and can easily be upgraded to an Eliptical needle which i heard is much better than Conical, i do not know how big the improvement to the sound will be but for now with stock AT300LA i dont any complains with how it performs.

Speed stability is commendable, supporting both 33 1/3 and 45 RPM playback with minimal wow and flutter (≤0.15% WRMS).

Additional Features
• RCA Grounding Cable: Helps reduce unwanted noise and interference.
• Removable Dust Cover: Protects the turntable and records when not in use. i have found out that removing the dust cover helps to minimize unwanted vibration.
• External Balance Adjustment: Allows fine-tuning of channel balance for optimal stereo imaging. but a volume or gain adjustment would have been more useful.
• Dual Power Supply: Supports both AC (100-240V) and DC (12V-1A), ensuring compatibility in various listening setups.

Comparison with Competitors
The FiiO TT13 sets itself apart in a crowded market of entry-to-mid-level turntables by combining premium build quality, full automation, and high-fidelity sound—a combination rarely found at its price point. While competitors like the Audio-Technica LP60X offer similar automatic tonearm operation, the TT13 steps ahead with a superior built-in preamp, better internal shielding, and a more powerful output signal (800mV at 1kHz, which is significantly stronger than many alternatives). These enhancements contribute to a cleaner, more dynamic sound with less interference, making the TT13 an appealing choice for those looking to simplify their setup without sacrificing audio quality.

Another key differentiator is the inclusion of Bluetooth with aptX HD, which allows for high-quality wireless streaming. Most turntables in the $150-$300 price range either lack Bluetooth entirely or offer lower-bitrate SBC connectivity, which can compromise audio fidelity. The TT13, on the other hand, provides a more dynamic, detailed wireless playback experience, making it an excellent option for users who want the flexibility of wired and wireless listening.

One area where some audiophiles might find limitations is the non-interchangeable cartridge head. The TT13 comes with the Audio-Technica AT3600LA, a well-regarded entry-level moving magnet (MM) cartridge known for its warm, engaging sound. However, while the stylus itself can be upgraded, the lack of a removable headshell means users won’t be able to swap out the entire cartridge for a different model. For beginners or those who prefer a hassle-free experience, this isn't an issue, but for those who enjoy tinkering and upgrading, it’s something to consider. That said, with the right stylus upgrade, the AT3600LA can unlock even more detail, refinement, and tracking accuracy, making it a solid foundation for long-term use.



Final Thoughts - A Turntable for the Modern Vinyl Enthusiast

The FiiO TT13 marks an ambitious and impressive first step into the world of vinyl turntables for a company primarily known for its digital audio expertise. Rather than simply releasing a standard entry-level turntable, FiiO has designed a product that seamlessly blends the classic warmth of analog sound with modern convenience, making it a compelling choice for both newcomers and vinyl enthusiasts.

One of the TT13’s biggest strengths is its fully automatic tonearm, which takes the guesswork out of playing records, ideal for those who want to enjoy their vinyl collection without the hassle of manual operation. At the same time, FiiO has paid attention to sound quality, equipping the TT13 with a strong built-in phono preamp that delivers a clean, high-output signal—outperforming many competing models in its price range. This means you can plug it directly into powered speakers or an amplifier without needing an external phono stage, making setup quick and effortless.

Build quality is another standout feature. The 4.5kg aluminum alloy chassis adds durability and helps reduce unwanted vibrations, while the substantial rubberized feet provide additional isolation, ensuring stable playback even in environments where external vibrations might be an issue.

While vinyl purists may eventually look to upgrade the cartridge for even greater refinement, the included Audio-Technica AT3600LA is a solid, well-regarded starting point, delivering a warm, engaging sound signature that pairs well with a variety of musical genres. While the TT13 does not offer a removable headshell for swapping out the cartridge, users can still upgrade the stylus to extract more detail and tracking accuracy as they become more invested in their vinyl journey.

The aptX HD Bluetooth connectivity makes it one of the few turntables in this price range that can wirelessly stream vinyl playback in high quality, offering an unexpected but welcome layer of versatility for those who enjoy both wired and wireless listening options.

Ultimately, the FiiO TT13 is a thoughtfully designed turntable that provides a smooth, user-friendly experience while maintaining high-fidelity sound quality. It’s a great entry point for those who want to dive into vinyl without the intimidation of fully manual turntables, and even experienced listeners will appreciate its blend of convenience, solid performance, and stylish design. Whether you are spinning your first record or adding it to an existing setup, i believe the TT13 proves that FiiO’s first venture into vinyl is a resounding success.

The Snowsky Retro Nano is a time machine in disguise. The moment I laid eyes on it, I was hit with a wave of nostalgia—it looks exactly like my old Soundwave toy from the '80s Transformers line. You know, the legendary cassette player robot that carried tiny cassette tapes in its chest? Those tapes would eject and transform into Laserbeak, the robotic eagle, and Rumble, the little menace with jackhammer hands capable of triggering earthquakes. Yeah, those were the days. And here I am, decades later, staring at this matchbox-sized audio device that somehow channels that same retro-futuristic charm.



But the Retro Nano isn’t just a gimmick—it’s shockingly good. Despite its cartoony aesthetic, this little device punches well above its weight class, outshining dongles that cost twice or even three times as much. Even when compared to the FiiO KA15, a more premium offering, the Retro Nano holds its ground in both sound quality and technical performance—sometimes even pulling ahead in certain aspects. And when it comes to LDAC mode, it completely outclasses the $180 FiiO UTWS5, delivering a more stable connection and superior sound quality. Where the UTWS5 sometimes stutters with pops and crackles in LDAC, the Retro Nano remains rock-solid with an impressive wireless range of up to 15 meters in a clear line of sight. As you can see in my photos, I tested it in AptX HD mode with the FiiO TT13 turntable, and to my surprise, it had no trouble driving my full-sized Sivga Anser over-ear headphones to loud volumes at just 60–70% output. That’s some serious firepower for such a tiny, pocketable device.

Under the hood, it packs dual CS43131 DAC chips, which are known for their clarity and detail retrieval but can sometimes lean cold, bright, or artificial if not implemented properly. However, Snowsky has nailed the tuning. The Retro Nano leans more toward the warm, natural tonality of an AKM DAC, rather than the sharper, more analytical sound that CS chips often exhibit. It never feels overly bright or sterile—it just sounds right.

For a device that looks like a toy and a bit cartoony aesthetics, the Retro Nano is an absolute powerhouse.

Whats included in the box? here is my quick unboxing video of the Retro Nano:



Design & Build
The Snowsky Retro Nano is delightfully compact, measuring just a bit larger than a matchbox. Its cassette-inspired design, with physical playback buttons adding to the tactile satisfaction. The 0.96-inch color display is small but effective, showing a fun tape animation while playing music. It’s a quirky touch that makes it feel more like an interactive gadget rather than just another DAC/AMP.

The dual headphone outputs (3.5mm SE + 4.4mm balanced) are a welcome addition, making it compatible with both casual listeners and audiophiles with balanced cables. Build quality is solid—lightweight yet sturdy, with a matte finish that resists fingerprints. The replaceable battery adds a practical edge, making it easy to swap in a fresh one if you’re on the go.

Equipped with Bluetooth 5.1, the Snowsky Retro Nano ensures a stable, lag-free connection. It supports LDAC, aptX Adaptive, aptX LL, SBC, and AAC, making it versatile enough for both casual and high-resolution streaming.

For wired setups, the USB DAC mode is a great option. It can run off its internal battery or draw power from a PC—handy if you want to preserve battery life on the go. The FiiO Control app adds another layer of customization, allowing users to tweak EQ settings and select from eight retro-inspired sound presets.
In a unique move, Snowsky included in-line microphone support, meaning you can take calls or use voice assistants without unplugging your headphones.

Battery Life – A Swappable Lifeline

The 7.5-hour battery life is respectable, especially when running high-power output or using LDAC. But what truly sets this device apart is its replaceable 3.7V 10440 lithium battery. Instead of being tethered to a charger, you can simply swap in a fresh battery and keep going—an absolute game-changer for on-the-go users.

This is a rarity in portable audio devices, and it’s a huge win, particularly for frequent travelers or anyone who hates downtime. As a flashlight geek with a literal wall of flashlights—everything from throwers and floodlights to LEPs and exotic EDC collectibles—I’ve accumulated an absurd number of rechargeable lithium batteries over the years. Seriously, it’s a lot. And if there’s one thing I’ve learned, it’s that battery performance depends on specs.

The capacity (mAh) and discharge rate of the 10440 battery you use will directly affect how long the Retro Nano runs. A higher-capacity battery with a lower discharge rate will extend usage time, while a high-discharge battery might provide more power but drain faster. This level of versatility is fantastic, and honestly, I wish more DAPs would adopt this trend of user-replaceable batteries.








Sound

Despite its playful, nostalgia-driven design and budget price the Snowsky Retro Nano takes sound reproduction surprisingly seriously. Under the hood, it houses dual CS43131 DAC chips, known for their clean, highly resolving nature, delivering a detailed and engaging audio experience. Its 220mW output (at 32Ω) ensures ample driving power for most IEMs and efficient headphones, making it a surprisingly capable performer despite its compact form factor.

To put it to the test, I ran a direct comparison with the FiiO KA15, a more expensive and well-regarded portable DAC/AMP. To my surprise, the Retro Nano held its own remarkably well. In fact, on certain tracks, I found myself preferring the sound of the Nano over the KA15, which was completely unexpected given the price difference. It’s one of those moments that makes you rethink the notion that a higher price tag automatically guarantees better performance.

The Retro Nano delivers a presentation that is clear, musical, and engaging, proving that it’s more than just a gimmicky retro-styled gadget—it’s a genuinely competent DAC/AMP.

But where the Retro Nano truly flexes its muscles is in LDAC mode. I compared it against the FiiO UTWS5, and the difference was night and day. The Nano exhibited a more stable LDAC signal, noticeably longer range, and—most importantly—none of the occasional crackling or dropouts that sometimes plague the UTWS5 in high-resolution streaming. It’s an area where Bluetooth DACs can often struggle, but the Qualcomm QCC5125 chipset inside the Retro Nano does an outstanding job of maintaining a strong, uninterrupted connection.
For something this compact and budget-friendly to go toe-to-toe with the KA15 and outright outclass the UTWS5 in LDAC performance is nothing short of impressive. It’s proof that Snowsky isn’t just playing around with nostalgia—they’ve built something that actually delivers where it matters: sound quality and wireless performance.

I put the Snowsky Retro Nano through its paces with a variety of IEMs and headphones, testing it in both wired USB mode (using the HiBy R6 III as a transport) and Bluetooth LDAC mode. What really stood out was just how close LDAC mode sounded to the wired connection—so close, in fact, that in most cases, I could barely tell the difference. That’s a huge win for anyone looking for the convenience of wireless audio without significant compromises in sound quality.

To get a well-rounded sense of its performance, I paired the Retro Nano with a mix of IEMs and a full-size headphone, including:

• FiiO FP3 – A well-balanced planar IEM that benefits from clean power and good dynamics.
• Dita Project M – An IEM with excellent clarity and resolution.
• Binary Dynaquattro – A quad DD IEM that demands good control and precision and has a natural, warm sound.
• Kiwi Ears KE4 – A neutral tuned IEM with a slight boosted subbass.
• Sivga Anser (Over-Ear Headphone) – A full-size headphone that provides a more spacious and immersive soundstage.
• I also paired the Nano with the FiiO TT13 turntable on Aptx-HD using the Sivga Anser. TT13 Review to follow soon

What impressed me was how effortlessly the Retro Nano drove each of these, maintaining a clean, controlled sound with good separation and dynamics across different driver types and tunings. Even with planars and hybrids, which can sometimes be more demanding, the 220mW of output power ensured that everything sounded full and properly driven.
But the real highlight? LDAC mode held up incredibly well against wired USB. Switching between Bluetooth and wired, the difference was barely perceptible, which speaks volumes about how well Snowsky has optimized its wireless performance. The Qualcomm QCC5125 chipset really does its job, providing a stable, high-resolution wireless experience with no noticeable compression artifacts or signal dropouts.
For a device this compact and feature-packed, the Retro Nano really is a welcome surprise for me, proving that Bluetooth audio—when done right—can get incredibly close to a wired setup.

Bass
The low-end is tight and controlled, with a slight emphasis that gives music a bit of warmth. It’s not bloated or overbearing, but it has enough punch to make bass guitars and drums feel engaging.

Mids
The midrange is clear and slightly forward, making vocals and instruments pop. There’s a touch of warmth that adds richness to the sound, particularly in the retro sound presets, which seem to add a bit of harmonic coloration reminiscent of vintage cassette recordings but not as gritty.

Treble
Treble is smooth and well-extended, avoiding harshness while still maintaining detail. Cymbals and string instruments have good shimmer, and there’s a nice sense of airiness without feeling artificial.

Soundstage & Imaging
For a device this small and at $50, the soundstage is impressive—wider than expected, with good depth. Imaging is precise, making it easy to place instruments in a mix. It’s not on the level of a dedicated desktop DAC/AMP, but for a pocket-sized device, it’s very capable.

Retro Sound Presets
One of the standout features of the Snowsky Retro Nano is its retro sound presets, which take you on a trip back to the golden age of cassette players and boomboxes. These presets aren’t just basic EQ tweaks—they’re designed to replicate the warm, slightly compressed character of classic tape decks, complete with subtle tonal shifts that mimic the quirks of old-school analog gear.

Some modes introduce a gentle treble roll-off, smoothing out the highs to recreate that soft, laid-back cassette warmth. Others boost the low-end, giving you that thick, punchy bass reminiscent of a ’90s boombox blasting hip-hop on a street corner or in a trunk of a car with some 10 inch subs, It’s not the purest, most audiophile-accurate tuning, but that’s not the point—these presets are about vibe, not neutrality.

For those who grew up with cassette tapes, these effects add an extra layer of nostalgia, making digital music feel a little more… imperfect in all the right ways. Whether you’re reliving the golden days of mixtapes or just want to add some flavor to your listening experience, the Retro Nano’s vintage sound profiles offer a fun, engaging twist that sets it apart from the usual sterile-sounding DACs.

Imagine sipping your morning coffee while flipping through a playlist on a device that looks like a mini cassette player but packs a serious punch in sound quality. That’s the Snowsky Echo Mini, a budget-friendly digital audio player (DAP) that doesn’t just bank on nostalgia—it delivers where it truly matters: sound, functionality, and sheer value.
At just $50, this pint-sized wonder doesn’t try to compete with high-end streaming DAPs or audiophile-grade gear, but it carves out a compelling niche. With dual CS43131 DACs, both 3.5mm and 4.4mm outputs, and support for high-resolution formats up to DSD256, it’s easily one of the most feature-packed budget players on the market. But does it live up to the hype?

Whats in the box? here is my quick unbox video:


Design & Build – A Nostalgic Throwback
Right out of the box, the Echo Mini is an instant eye-catcher. Designed to resemble a miniature cassette tape, it taps into the retro charm of the ’80s and ’90s while blending modern functionality. The 1.99-inch IPS color display is crisp, though compact, featuring a fun animated cassette UI. Despite weighing only 55g, the Echo Mini feels surprisingly solid and well-constructed. While the body is made of plastic, it doesn’t feel cheap in the slightest. In fact, when I first held it, I mistook the front panel for metal—it has that sturdy, premium feel. Compared to the HiBy R1, the Echo Mini feels more robust and refined in hand. I also appreciate the sharp edges, which give it a sleek, modern touch while still maintaining its retro-inspired aesthetic.

Available in Black, Cyan, and Pink, it caters to different aesthetic tastes. The buttons offer satisfying tactile feedback, and the overall layout is intuitive, simple enough for casual users while offering enough depth for more seasoned listeners.

Features & Functionality:

For an entry-level DAP, the Echo Mini doesn’t skimp on features:

• Dual CS43131 DACs – A rare find at this price, these DACs ensure clean, detailed sound with low distortion.
• 3.5mm single-ended & 4.4mm balanced outputs – Uncommon in this price range, the balanced output delivers up to 250mW at 32Ω, making it powerful enough to drive most IEMs and even some headphones.
• Full format support – WAV, FLAC, DSD256, MP3—if it’s a music file, chances are the Echo Mini can play it.
• Bluetooth support – A nice bonus for those who want wireless convenience.
• Built-in 8GB storage + microSD expansion (up to 256GB) – While 8GB isn’t much, the microSD slot makes up for it.
• Long battery life – Respectable playback time, especially given its small size.

The only major omission? No Wi-Fi or streaming support. But at this price, expecting Tidal or Spotify integration would be wishful thinking. This is a pure offline player, which can be a dealbreaker for some but a blessing for audiophiles who want to disconnect and focus on their music.





Sound Quality – Surprising Clarity for the Price

Budget DAPs often fall into one of two traps: overly processed sound that feels artificial or lackluster DAC implementation that leaves the music lifeless. The Echo Mini, however, defies these expectations, delivering a level of performance that punches well above its class.

Thanks to its dual DAC setup and independent power supply system, the Echo Mini offers a sound signature that’s clean, dynamic, and highly engaging. It leans towards a neutral presentation with a slight brightness, giving it a crisp, airy character without veering into harshness. If you're familiar with FiiO’s house sound, you'll immediately recognize its influence here—neutral yet slightly bright, with excellent clarity, detail retrieval, and precise imaging. It's the kind of tuning that brings out microdetails in recordings while maintaining a natural and spacious presentation, making it a compelling option for those who appreciate a more analytical but still musical sound.

Bass
The low end of the Echo Mini is tight, controlled, and well-defined, prioritizing texture and accuracy over sheer impact. It doesn’t aim to overwhelm with excessive boom, but rather delivers a refined and articulate bass response that complements a wide range of genres.

Sub-bass extension is good, reaching deep without muddying the mix, allowing rumbling notes to be felt rather than just heard (depending on what iem or headphone you use.) Meanwhile, midbass carries enough punch and body to keep the sound lively and engaging, adding warmth where needed without bleeding into the mids. It strikes a great balance—there’s enough weight to give drums and basslines a satisfying presence, but not so much that it overpowers the rest of the frequency range.


Mids
Vocals on the Echo Mini are clear, detailed, and slightly bright, which brings out nuances in both male and female voices. However, in some tracks, this brightness can make vocals sound a bit thin, lacking the full-bodied weight that gives them a more natural and organic presence. While it’s not the warmest or most euphonic midrange, there is just enough warmth to add a touch of richness and emotion—enough to keep vocals engaging without muddying the overall presentation.

Instrument separation is handled well, allowing complex arrangements to remain distinct and easy to follow. Acoustic guitars have a crisp bite, pianos resonate with good clarity, and string instruments maintain their delicate textures. The tonality is balanced and largely uncolored, ensuring that instruments sound true to the recording. The mids remain clean and highly detailed, making this tuning ideal for those who prioritize clarity, resolution, and transparency over a warmer, more colored presentation.


Treble
The treble is energetic, bright, and well-extended, giving the sound an open and airy presentation. Highs are crisp without being piercing, striking a nice balance between clarity and smoothness. There's enough brightness to bring out fine details and microtextures, but it avoids becoming overly sharp or fatiguing, making long listening sessions more enjoyable.

There’s a good amount of air and sparkle, which enhances instrument separation and adds a sense of spaciousness to the sound. Detail retrieval is impressive for the price, allowing subtle nuances—like the shimmer of cymbals or the delicate decay of high notes—to come through with remarkable clarity. While it leans toward a more revealing treble, it manages to stay controlled, ensuring that sibilance is kept in check.

Soundstage & Imaging
For such a compact and budget-friendly device, the Echo Mini delivers a surprisingly spacious soundstage, especially when used in balanced mode. While it won’t match the vast, out-of-head experience of high-end DAPs, it does an impressive job of creating a sense of openness. There’s a good amount of width and depth, allowing instruments and vocals to breathe rather than feeling cramped or congested.

Imaging is precise and well-defined, making it easy to pinpoint the location of different instruments in complex tracks. Whether it's the placement of a vocalist front and center, a guitar off to the side, or subtle background elements, the Echo Mini keeps everything distinct and well-separated.





Usability & Performance – Compact but Capable

The RTOS-based OS is simple but snappy. Boot times are fast, navigation is intuitive, and playback is lag-free. The interface isn’t as polished as premium DAPs, but it gets the job done.

The buttons are a welcome touch—no need for a touchscreen, just simple, reliable controls that work without distractions.

In terms of drivability, the balanced output (250mW @ 32Ω) can handle a variety of IEMs and even some full-sized headphones. Low-impedance, high-sensitivity IEMs work best, but even slightly harder-to-drive sets get ample power without distortion.



Final Verdict – A No-Brainer for Budget-Conscious Audiophiles

The Snowsky Echo Mini is one of the best bang-for-your-buck digital audio players available today.

It doesn’t try to be a high-end DAP, nor does it pretend to replace your smartphone for streaming. Instead, it excels at what a DAP should do: deliver pure, high-quality music playback in a compact and stylish form factor.

For $50, it’s an absolute steal. If you’re looking for a budget-friendly, high-resolution, no-frills music player with great sound quality, balanced output, and nostalgic charm, the Echo Mini is a no-brainer.

Would it be better with streaming? Sure. But sometimes, less is more, and in a world of distractions, having a dedicated offline player that just plays music beautifully is a refreshing change.

Highly recommended for budget-conscious audiophiles and casual listeners alike.

After spending a considerable amount of time with the Twistura Sigma, I’ve come to appreciate its strengths while also recognizing a few quirks that make it a bit of a mixed bag. These latest hybrid, bullet-style in-ear monitors from Twistura strive for a balanced and neutral sound signature—an approach that, in many ways, they execute well. However, as with most audio gear, perfection is elusive, and the Sigma does have its fair share of nuances that might appeal to some listeners while leaving others wanting more. In this review, I'll dive deep into its performance, breaking down where it excels, where it stumbles, and who might find it to be the right fit for their listening preferences.

Whats in the box? here is a quick unboxing video.





Unboxing and Accessories
Let’s start with the unboxing experience, because Twistura has clearly put a lot of thought into the packaging. Opening the box feels like unwrapping a premium product, and the included accessories only reinforce that impression. Inside, you’ll find a generous selection of items that add real value to the overall package. Alongside the IEMs themselves, you get:

- A USB DAC (a thoughtful addition for those who want to jump straight into high-quality audio without needing to buy extra gear).
- Six pairs of ear tips (ensuring a comfortable and secure fit for a wide range of ear shapes and sizes) its really inmportan to have the perfect size and shape eartips for a bullet style IEM to have that perfect fit and seal.
- A sleek leather clasp-style pouch (Same as the ones you get in the Hidizs iem, it very convenient since all that is included in the box, iem, impedance adaptor and the usb DAC fits in the pouch for a perfect ultra-portable setup).
- An impedance adapter (a somewhat unexpected but welcome inclusion).

The impedance adapter is an interesting addition. Typically, these are used to reduce floor noise in more sensitive IEMs, but the Sigma isn’t particularly sensitive, which makes its inclusion a bit puzzling. That said, it’s a nice bonus for those who might use it with other, more sensitive audio gear.

Overall, the unboxing experience sets a high standard, and the accessories make it clear that Twistura is aiming to deliver more than just a pair of IEMs—they’re offering a complete, compact and ultra-mobile package.

Build and Design

The Twistura Sigma embraces a classic bullet-style design, which is both compact and ergonomic. This shape not only looks timeless but also ensures a comfortable fit, making it an excellent choice for extended listening sessions. The IEMs sit snugly in the ear without causing fatigue, which is a big plus for anyone who spends hours immersed in music.

Build quality of the Sigma strikes a fine balance between durability and aesthetics. The shiny chrome alloy shell is seamlessly combined with a clear, translucent resin that offers a glimpse of the tiny 6mm driver inside. It is a neat touch that adds a bit of visual intrigue without being overly flashy. While the Sigma don’t scream luxury, it gives a sense of understated elegance. The design is clean, functional, and thoughtfully executed, which aligns perfectly with the Sigma’s overall tuning philosophy—focused on delivering a no-nonsense, balanced listening experience.

The finish is smooth to the touch, and the overall construction feels solid enough to withstand daily use. The bullet-style form factor also makes these IEMs highly portable, easily slipping into a pocket or it leather pouch without taking up much space. While it may not have the heft or opulence of some more pricey IEMs, the Sigma’s design is practical, stylish, and built to last.

Sound Signature
The Twistura Sigma offers a neutral-leaning sound signature with a slight touch of warmth, making it more natural and easygoing rather than clinical or overly analytical. It’s a tuning that prioritizes balance and accuracy, catering to those who appreciate a more refined and true-to-source presentation. While this makes it a solid choice for critical listening, it may come across as a bit too restrained for those who prefer a more colored, energetic, or engaging sound. If you’re someone who enjoys a bit of extra punch in the bass or some added sparkle in the treble, the Sigma might feel a little too polite—but for those who value precision and a smooth, non-fatiguing listening experience, it strikes a compelling balance.



Bass
The Twistura Sigma’s bass is all about control and precision rather than sheer impact. It leans towards a midbass-focused presentation, delivering a tight, well-defined punch rather than a deep, rumbling subbass experience. This means kick drums and bass guitars come through with a clean and articulate presence, but you won’t get that earth-shaking low-end extension that some listeners crave.
While the bass is quick and well-textured, it lacks the weight and physicality that would satisfy bassheads or those who enjoy a more visceral, cinematic low end. However, this restraint works in its favor for genres that thrive on clarity and speed—think jazz, acoustic, and even some forms of classical music to rock. The bass remains neatly separated from the mids, avoiding any unwanted bleed, which helps maintain an overall sense of balance. If your priority is accuracy and cleanliness over raw impact, the Sigma’s bass performance is commendable.

Midrange
The midrange is where the Twistura Sigma truly comes into its own, and it’s easily the standout feature of these IEMs. The presentation here is layered, natural, and deeply engaging, offering a tonality that feels authentic and true to the source. Whether you’re listening to a soulful vocal performance or the intricate plucking of an acoustic guitar, the Sigma delivers a level of realism that makes the music come alive.

Vocals are particularly well-rendered, sitting front and center in the mix without ever feeling overpowering or recessed. They have a warmth and clarity that feels intimate, as if the artist is right there in the room with you. This makes the Sigma an excellent choice for vocal-forward genres like jazz, folk, or singer-songwriter tracks, where the emotional nuance of a performance is key.

Instruments, too, benefit from the Sigma’s midrange prowess. Acoustic guitars have a satisfying resonance, pianos sound rich and full-bodied, and strings carry just the right amount of texture and detail. There’s no harshness or artificial coloration to be found—just clean, well-defined mids that strike a perfect balance between accuracy and musicality.

What’s particularly impressive is how the Sigma manages to maintain this level of clarity and naturalness without sacrificing cohesion. The midrange doesn’t feel detached or overly analytical; instead, it blends seamlessly with the rest of the frequency spectrum, creating a cohesive and immersive listening experience, like me that values a midrange that is both technically proficient and emotionally resonant.

Treble:
Unfortunately, the treble is where the Sigma stumbles a bit and it’s arguably the weakest link in an otherwise impressive audio profile. While the midrange and bass deliver a well-rounded experience, the treble feels somewhat restrained and lacking in energy. There’s a noticeable roll-off in the upper frequencies, which results in a presentation that’s less extended and airy than what you might expect from an IEM thats is from Twistura which form my experience with previous models have a focus on treble energy and bright overall tonality.

This roll-off has a couple of consequences. First, it robs the sound of that last bit of sparkle and brilliance that can make cymbals shimmer, violins sing, and high hats cut through with precision. As a result, the overall sound signature can feel a bit closed-in and less dynamic, especially when compared to IEMs with a more pronounced or refined treble response. For genres like classical, jazz, or electronic music—where a lively and detailed top end is crucial—the Sigma’s rounded treble performance can feel a bit underwhelming.

That said, there’s a silver lining here for those who are particularly sensitive to sibilance or harshness in the treble. The Sigma’s restrained approach ensures that even poorly recorded tracks or overly bright recordings remain listenable, without any piercing or fatiguing peaks. It’s a trade-off that might appeal to listeners who prioritize long-term comfort over outright detail retrieval.

Ultimately, while the treble doesn’t ruin the experience, it does hold the Sigma back from reaching its full potential. A bit more extension and energy in the upper frequencies could have elevated the overall sound, making it more versatile across a wider range of genres. As it stands, the treble is serviceable but leaves you wishing for just a little more brilliance and openness.

Technicalities.
The soundstage on the Twistura Sigma is fairly average in width, offering just enough space and depth to create a sense of openness without feeling overly expansive. It doesn't stretch particularly wide, but it avoids feeling cramped, maintaining a natural presentation that works well for most genres.

Where the Sigma really shines is in its imaging and separation. Instruments and vocals are placed with good accuracy, making it easy to distinguish different elements within a track. While it may not have the pinpoint precision of higher-end IEMs, it does a commendable job of keeping layers distinct without blending sounds together.

Dynamics are also handled well, with a decent sense of contrast between soft and loud passages. While it doesn’t deliver the kind of explosive energy that some more aggressive tunings offer, it still provides a lively enough presentation to keep the music engaging.


Power Requirements
One surprising aspect of the Sigma is its power requirements. Despite its compact drivers, it demands more power than I initially expected. This isn’t necessarily a dealbreaker, but it’s something to keep in mind if you’re planning to use it with lower-powered sources like smartphones. The included USB DAC helps mitigate this issue, but it’s worth noting that the Sigma isn’t the most efficient IEM out there.

Comparisons
In many ways, the Sigma shares a similar tuning philosophy to the Kiwi Ears KE4 and also the Tanchjin 4U another neutral, balanced IEMs. However, the KE4 edges out the Sigma with its fun, boosted subbass and more energetic treble. The Sigma, by comparison, feels more polite and reserved. It’s a solid offering, but it lacks the excitement and dynamism that make the KE4 stand out.

Who Is It For?
The Twistura Sigma is a great choice for listeners who prioritize a neutral, balanced sound signature and value a natural midrange. It’s well-suited for genres like acoustic, jazz, and classical, classic rock, where accuracy and tonality are key. However, if you’re someone who craves a more exciting, V-shaped sound with thunderous bass and sparkling treble, the Sigma might feel a bit too restrained.




Final Thoughts

The Twistura Sigma is a well-rounded IEM that brings a lot to the table, especially for its price. With a neutral tuning that leans slightly warm, it delivers a smooth and natural sound that feels both refined and easy to listen to. The midrange is undoubtedly the star of the show—vocals and instruments come across with a sense of authenticity and warmth that makes long listening sessions enjoyable. It’s an IEM that prioritizes balance and coherence rather than chasing extreme bass or treble emphasis.

That said, it may not be for everyone. The subdued treble means you won’t get that extra sparkle and airiness that some listeners crave, and the subbass, while present, doesn’t hit with the depth and authority that bass lovers might hope for. While it’s a solid performer, it doesn’t necessarily deliver the kind of excitement or standout technical prowess that would make it a category-defining product.

If you’re after a polite, natural-sounding IEM with a smooth, mid-focused presentation, the Sigma is definitely worth considering. But if you prefer a more energetic, dynamic, or V-shaped tuning with a bit more punch and treble sparkle, you might want to explore other options.

As a DAC Amp Preamp

Using the K7 as a DAC preamp for my passive bookshelf speakers, paired with the Fosi Audio MC331 tube amp, the synergy was remarkable. The K7’s clean, articulate sound signature complements the smooth, balanced tonality of the MC331. With 5654W tubes, the MC331 adds a warm, organic layer to the already refined sound of the K7, enhancing midrange detail and vocal richness.

The bass is authoritative—weightier, textured, and slightly more rounded than my Xduoo MH-02 with stock Chinese 6J1 tubes. It’s not boomy or exaggerated but instead delivers tight, musical low-end performance that fills the room with warmth and body.

The midrange is where the combo truly shines. It’s lush, organic, and slightly romantic. Vocals are creamy and emotional, making acoustic tracks feel intimate and captivating. Instruments like guitars and pianos come through with natural timbre, a hallmark of AKM DACs when implemented well.

The highs are smooth and well-extended, offering airy detail without harshness. Cymbals and strings have a refined sparkle that avoids sibilance, making long listening sessions fatigue-free.






Gaming Performance

When it comes to gaming, the Fosi Audio K7 is in its elements. I tested it as a gaming DAC/amp by pairing it with my Meta Quest 2 VR goggles over Bluetooth using the aptX LL codec, alongside the 7Hz Elua IEMs. The low-latency connection was flawless, delivering near-zero lag even during the most intense, fast-paced gaming moments. For my test, I dove into Iron Rebellion VR, a mech combat simulator that demands both precision and immersion—and the K7 didn’t disappoint.

The experience was nothing short of jaw-dropping. The AKM DAC chip’s incredible detail retrieval and holographic spatial sound brought the game to life in a way that felt cinematic. The weighty thuds of my mech’s footsteps felt impactful, the explosions were deep and earth-shaking ( thanks to the deep rumbly subbass of the 7hx elua) and the metallic clangs of battle echoed with realism. The K7’s imaging is so precise that I could pinpoint the trajectory of incoming missiles with remarkable accuracy, giving me a distinct competitive advantage.

It’s not just the clarity and precision that impressed me, though—it’s how immersive everything sounded. The soundstage felt vast and three-dimensional, enveloping me in the game’s environment. The details were so vivid that I could hear subtle cues, like the faint whirring of a distant mech preparing to engage or the subtle hiss of hydraulics under strain. These nuances added a new layer of depth to the gaming experience, making it not just fun but downright exhilarating.



I’ve included a gameplay video from my testing session with the K7. Turn up the volume, and you’ll get a taste of just how intense and immersive the experience is—especially during those frantic combat moments. You can hear every ping, crash, and explosion with crystal clarity, showcasing just how well the K7 handles the chaos of battle.

The K7 proved itself as more than just a capable gaming DAC/amp—it’s an immersive powerhouse that enhances both the emotional and competitive aspects of gaming. If you’re into fast-paced shooters or atmospheric RPGs, it’s a device that brings every detail to life.



Final Thoughts

The Fosi Audio K7 punches well above its weight, offering versatile functionality, excellent sound quality, and gamer-friendly features at an affordable price. Its warm, detailed sound signature makes it a standout for music lovers, while its immersive imaging and usb type c or aptX LL Bluetooth performance make it a perfect companion for gaming.

For a DAC/amp that balances audiophile-grade sound with excellent gaming performance, the Fosi Audio K7 is hard to beat. It’s an intuitive, polished device that will enhance both your listening and gaming sessions.

The cable doesn’t just feel high-end; it also performs exceptionally, minimizing signal loss for a clean and precise audio transmission and no microphonics.

Then there’s the leather carrying case, It’s well-crafted black leather with a soft yet sturdy finish, and the added hand strap is a nice touch that enhances both functionality and style. Together, these accessories complete the T7 package, making it clear that TinHiFi has put as much thought into the user experience as they have into the sound and design. This isn’t just an IEM—it’s a well-rounded, premium package that caters to users who appreciate both form and function.

I have to be honest—this might sound like I’m overhyping the T7, but I genuinely believe it’s the best single dynamic driver IEM in my collection to date. Sure, I know there will always be new contenders in the future, but for now, the T7 firmly holds the crown as the single DD GOAT in my lineup. And trust me, my collection of single dynamic driver IEMs is no small stable—I’ve heard my fair share of excellent ones.

What makes the T7 so special is how it just gets everything right. The sound is beautifully balanced, detailed, and natural, with a tuning that feels both engaging and versatile across genres. The build quality is equally impressive—it’s solid, elegant, and comfortable enough for long listening sessions. The design? Timeless and understated, with thoughtful touches that elevate its aesthetic appeal. And then there’s the pricing, which feels almost too good for what you’re getting.

The T7 isn’t just a great IEM—it’s the full package. It strikes that rare balance of performance, craftsmanship, and value that’s hard to come by, and that’s why it’s earned a special place in my collection.



The TinHiFi T7’s sonic performance is nothing short of impressive. Armed with its patented ultra-linear dual Tesla magnetic drivers and gold-plated diaphragm, the T7 delivers a sound signature that is smooth, balanced, and highly detailed. Its ability to reproduce music with natural precision and without artificial enhancements is its defining strength.

Bass
The T7's bass strikes a perfect balance of depth, accuracy, and texture. The subbass digs deep with a satisfying rumble when called upon, while the midbass is punchy, agile, and tightly controlled. Its clear and fast transients add an extra layer of energy and definition, making the bass feel lively and precise. Each note is well-layered and detailed, creating a rich foundation that supports the music without ever overwhelming the mids.

Mids
The mids on the T7 are wonderfully natural and full-bodied, with just a hint of warmth that breathes life into vocals and instruments alike. The tonality is spot-on, delivering a lifelike timbre that feels both authentic and emotionally engaging. Vocals are slightly forward in the mix, striking the perfect balance between intimacy and spaciousness—they draw you in without ever feeling cramped. Both male and female vocals are rendered with impressive accuracy, showcasing their unique textures and emotions. Meanwhile, midrange instruments like guitars, pianos, and strings are beautifully detailed and well-defined, with excellent separation and clarity that make every note shine. It's a midrange that feels as though it was tuned with genuine care, adding depth and soul to the overall presentation.

Treble
The treble is, without a doubt, the T7's crowning achievement. As I mentioned in a previous post, the T7 delivers a masterclass in treble control and refinement. It’s airy, beautifully detailed, and extends effortlessly, all without ever crossing into sharpness or fatigue. This is the kind of treble that adds a gentle sparkle to the sound, enriching the upper frequencies without overpowering the rest of the spectrum.

What truly makes it special is its ability to enhance the overall presentation—it creates a sense of spaciousness and clarity that feels completely natural and organic. Instruments like cymbals, hi-hats, and strings shimmer with just the right amount of brilliance, while subtle micro-details are revealed with precision, adding an extra layer of immersion to your music. The balance here is exceptional; it’s controlled yet lively, refined yet dynamic. It’s this perfect harmony between technicality and musicality that makes the treble not just a highlight, but a defining feature of the T7.







Soundstage & Imaging
The soundstage of the T7 is wide, providing a good sense of space, though it leans more towards width than depth. However, what truly stands out is the imaging and instrument separation. The precision with which the T7 places instruments and vocals in the soundscape is remarkable, rivaling that of many multi-driver IEMs. It’s surprising how a single dynamic driver can achieve such clarity and separation while maintaining the natural, cohesive tone typically associated with dynamic drivers.

The fit is secure, with an excellent seal that enhances passive noise isolation. Whether you are working, or simply relaxing over a cup of espresso, the T7 disappears into the ears, allowing you to focus solely on the music.



Final Thoughts

The TinHiFi T7 is a triumph of thoughtful design and engineering. It bridges the gap between tradition and modernity, delivering a sound signature that is both accurate and emotionally engaging. With its premium build, exceptional comfort, and outstanding sonic performance, the T7 stands out as a versatile and capable IEM that can compete with offerings well above its price point.

If you value natural tonality, refined treble, and an immersive listening experience, the T7 deserves a spot in your collection. TinHiFi has once again proven that high-quality audio doesn’t have to come at an exorbitant cost—it just takes the right blend of artistry and innovation.

Instant Classic!

The Hidizs ST2 PRO Nebula is a bold step forward in the IEM space, blending the simplicity of a single dynamic driver with the power of a high-performance DAC cable. At first glance, it may look like just another Type-C IEM package, but a closer look reveals a game-changing feature: the cable itself doubles as a fully-fledged DAC. Powered by the ES9281AC PRO chip (found in a full sized dac devices like the Astell&Kern AK-HB1 and Fiio KA1), the ST2 PRO delivers an impressive 70mW of power, proving that big things do come in small packages, and i do believe this is the next innovative step to the ultra portable setup.

Whats in the box? here is a quick unboxing video:


Here’s what you get:

ST2 PRO IEMs

USB-C DAC Digital 0.78mm 2Pin Earphone Cable

Three pairs of silicone eartips

USB-C to USB-A adapter

Leather Hidizs pouch bag

Warranty card

Product quality certificate

Design & Build Quality

The ST2 PRO Nebula’s design strikes a balance between form and function. The cable showcases an aluminum alloy USB connector, with transparent windows on either side to reveal the internal PCB. A small LED indicator provides real-time feedback on audio sampling rates—red for PCM (44.1-48kHz) and blue for PCM (88.2-384kHz) or native DSD playback.

The in-line controls and splitter are similarly crafted from aluminum alloy for that extra durability. While the earphone connectors are unfortunately plastic, the build overall feels good for the price point.

The cable measures 1.2 meters and is made from high-purity oxygen-free copper wires wrapped in a textile material for enhanced flexibility and durability. It’s soft, lightweight (just 16 grams), and resists microphonics well. However, it does feel a bit delicate—something to consider if you’re rough with your gear.

Color options include a sleek silver-gray and a striking black-blue, both of which complement the minimalistic yet modern aesthetic.



This sound impression is based on using the ST2 Nebula IEM, but I've also paired the cable with various other IEMs, including planar drivers. It’s incredibly impressive how well the cable handles planars, delivering generous volume with plenty of headroom to spare. I’m genuinely impressed with how effectively the ES9281AC PRO chip is implemented here. The level of detail, clarity, and power packed into such a small device is quite surprising.

I’ve tried a lot of DSP cables, but none come close to the performance of the ST2. If there’s a next iteration of this cable, I’d love to see a more premium version with thicker cables and metal connectors—it would make an already impressive product even better.

For some reason, my graph measurements don’t seem to fully reflect the actual sound of the ST2. When measuring the ST2 IEM with the DAC cable, the graph shows a subbass roll-off that’s not present in real listening. Similarly, when using a regular cable, the graph shows a noticeable peak in the upper treble, which isn’t accurate based on what I hear. It’s a reminder that graphs can be helpful, but they don’t always tell the whole story.


Hidizs has tuned the ST2 PRO Nebula to a slightly tweaked Harman curve, creating a sound profile that's fun, engaging, and surprisingly versatile. One area where this tuning truly shines is gaming. For me, the ST2 PRO feels tailor-made for immersive gameplay. Paired with my MetaQuest 2 VR goggles, it delivers exceptional spatial audio performance. The 3D soundscape is impressively detailed, with precise imaging that places every sound exactly where it should be. It wraps you in a fully immersive audio environment, making every gaming session feel incredibly lifelike and engaging.

Bass
The subbass on the ST2 PRO Nebula is generous, it deep and resonates delivering a satisfying rumble that adds depth and weight to tracks, particularly in genres like electronic, hip-hop, or cinematic scores. It’s the kind of subbass that makes you feel the music, not just hear it. The midbass follows up with a punchy, impactful presence, though its slower decay can sometimes bleed into the lower mids. Interestingly, this bass bleed doesn’t detract from the overall experience; instead, it adds warmth and body to the midrange, creating a cohesive and inviting sound signature. This characteristic works especially well for gaming, where impactful and immersive bass can heighten the experience.

Midrange
The midrange is slightly recessed, which might leave vocals and instruments positioned a step back in the mix compared to the bass and treble. Despite this, the mids maintain a natural timbre and tonal accuracy, which helps them feel lifelike and engaging. The clarity is respectable, though the midrange lacks the intricate layering or microdetails that more analytical listeners might crave. However, its smooth and warm presentation makes it well-suited for casual listening, particularly with vocals and acoustic tracks that benefit from its organic tonality.

Treble
The treble performance is a standout feature of the ST2 PRO Nebula. Energetic and well-extended, the highs bring a sense of air and sparkle to the overall sound signature. This added clarity balances out the warmth from the bass, ensuring that the sound never feels overly dark or congested. The treble's extension also contributes to uncovering fine details in the music, enhancing the perception of resolution across the frequency spectrum. Importantly, it avoids harshness or sibilance, making it suitable for long listening sessions without fatigue. The treble’s liveliness adds refinement and helps tie the entire sound signature together, making it dynamic and engaging for various listening scenarios.

The soundstage is average in width and depth, providing a focused, intimate listening experience rather than an expansive one. Imaging is precise, making it easy to pick out instruments and positions in the mix.

Resolution & Dynamics

For its price, the ST2 PRO Nebula punches above its weight in resolution. It captures subtle details and nuances in listening to music and in gaming, making it a capable performer for music and even in VR gaming. You’ll hear microdetails in recordings and soundscapes that you might miss with lesser gear. Dynamics are equally strong, effortlessly transitioning between quiet and loud passages with ease.

DAC Cable Performance:

The integrated DAC cable is where the ST2 PRO truly shines. Equipped with the ES9281AC PRO chip, the cable delivers enough power to drive even demanding planar IEMs without breaking a sweat. It handles volume adjustments smoothly, with plenty of headroom to spare.

What’s impressive is the level of portability this DAC cable brings. It bridges the gap between traditional USB dongles and standard IEM cables, offering the same performance as many dongles while remaining far more compact. For ultra-mobile audiophile setups this is a game-changer.

While the ST2 PRO Nebula excels in many areas, there’s room for refinement:

Bass Control: The midbass decay could be tighter to avoid occasional bleeding into the mids.

Midrange Detailing: While pleasant, the mids could use more layering and resolution to appeal to analytical listeners.

Build Durability: The lightweight cable, while flexible and comfortable, feels slightly delicate. A thicker, more premium version would be a welcome addition—even at a higher price point.

Final Thoughts:

The Hidizs ST2 PRO Nebula showcases just how far compact audio solutions have come. It’s a versatile IEM that combines great sound with innovative DAC technology, all in a package that’s as portable as it is powerful. Personally, I’d choose this kind of ultra-portable setup over a full-sized USB dongle DAC any day. Plus, I’ve finally found a use for that included Hidizs leather pouch—it’s perfect for carrying this setup around.

For an IEM that delivers stellar sound quality, impressive DAC capabilities, and unmatched portability, the Hidizs ST2 PRO Nebula is a tough contender to beat at its price.

The Apevoix Grit marks a bold debut for a relatively unknown brand in the audio world. Despite scouring the internet for any background information on Apevoix, I came up empty-handed. That said, the Grit immediately caught my attention with its premium design and packaging. With a back panel reminiscent of the Unique Melody Mest MK2 and a rugged, Pelican-style case, the Grit certainly doesn’t shy away from making a strong first impression. Inside the case, you’ll find a selection of silicone tips, a pair of foam tips, and a high-quality graphene silver-plated cable—one that closely resembles my KBear Chord Graphene cable.

Beyond its aesthetics and accessories, what truly sets the Apevoix Grit apart is its cool driver configuration. It features a 1 dynamic driver (DD), 4 balanced armature (BA) drivers, and 1 bone conduction (BC) driver, all working together in a sophisticated 4-way crossover network. This tribrid setup is designed to deliver a detailed, textured, and rich sound signature that can rival more established competitors in the market, such as the Pula Anvil.
That said, I haven’t had the chance to try the Anvil for a direct comparison. The Grit is my first tribrid IEM equipped with a bone conduction driver, and it’s left a strong impression. It offers a unique listening experience for me.

Whats in the box? heres a my quick unbox video of the Apevoix Grit.


Accessories and Cable

The accessory package that comes with the Apevoix Grit is fairly straightforward but well thought out. The included cable is a Graphene silver-plated cable that feels identical to the KBear Chord—one of my personal favorites. It exudes a premium quality, with a smooth, neutral sound transmission and zero microphonics. The cable not only complements the IEMs aesthetically but also performs exceptionally well in daily use.

The standout accessory, however, is the carry case. It’s a rugged, Pelican-style case with an eye-catching red color that sets it apart. The case is incredibly sturdy, offering excellent protection for your IEMs while providing enough room to store a dongle DAC or a few other small accessories. It’s practical, durable.

As for ear tips, the Grit includes three sets that provide decent variety for achieving a proper fit. While the selection isn’t exhaustive, it should be sufficient for most users to find a comfortable seal. Overall, the accessories strike a nice balance between functionality and quality, with the cable and case being particular highlights.

Sound Profile: Here is the FR graph i took on the Grit.

Bass

The bass performance of the Apevoix Grit is driven by a 10mm dynamic driver with a biocellulose diaphragm, and it’s evident that Apevoix has put significant effort into tuning this driver with care and precision. The midbass takes center stage, offering a punchy, powerful performance that is smooth, detailed, and textured. Despite its prominence, the bass avoids veering into overwhelming territory, ensuring it integrates harmoniously with the rest of the frequency range.

The midbass brings warmth and body to tracks, forming a rich and satisfying foundation that enhances bass guitars and kick drums. These elements come across as full and engaging, with a natural weight that hooks you into the rhythm. The subbass, while present, adopts a more reserved role. Rather than delivering a ground-shaking rumble, it provides a controlled, subtle resonance that adds depth without overshadowing the midbass or creeping into other frequency ranges.

While the Grit may not cater to hardcore bassheads seeking skull-rattling subbass, it still qualifies as a bassy IEM, the subbass goes really deep but does not linger much making it an excellent companion for bass-heavy genres like house, techno, and hip-hop. What truly sets it apart is the level of layering and detail in the midbass—it’s impressively textured and nuanced, bringing an analytical edge to an otherwise musical bass presentation.

For those who prioritize clarity, texture, and balance in their low-end experience, the Grit strikes a beautiful balance between impactful bass and refined control, delivering a sound that is both fun and refiend.

Mids

The mids are undoubtedly the heart and soul of the Apevoix Grit. Compared to the Binary Dynaquattro, the Grit makes the Dynaquattro’s mids feel slightly recessed by comparison. With the Grit, vocals feel as though the singer is performing just a meter away, creating an intimate and immersive experience. The mids are forward, lush, and warm, delivering an astonishing level of detail and emotional engagement.

Thanks to the pair of dedicated BA drivers, the midrange is not only vivid but also incredibly articulate. Female vocals, in particular, stand out with their natural timbre, breathing life and authenticity into each track. Instruments like acoustic guitars and pianos showcase a delightful texture and warmth, making them feel as if they're being played right in front of you.

If you enjoy vocal-centric genres, mid-focused tracks, or acoustic instrumental music, the Apevoix Grit’s midrange truly shines. It delivers a rich, captivating presentation, and thanks to the bone conduction driver, the mids are imbued with a slightly meatier, lush texture. Impressively, this added warmth doesn’t compromise the clarity or natural tonality of female vocals or higher-pitched voices. They remain crisp, detailed, and beautifully natural, making the Grit a fantastic choice for those who prioritize an engaging midrange performance.

Treble

The treble, driven by an additional pair of balanced armature (BA) drivers, strikes an impressive balance between detail and smoothness while maintaining a textured and airy quality. High frequencies are extended and well-articulated, delivering a sense of air and openness without ever veering into harshness or sibilance. Cymbals, strings, and high-pitched vocals shine with remarkable clarity, adding an energetic sparkle that complements the overall sound.

What stands out most is how non-fatiguing the treble is, even during extended listening sessions, The inclusion of the bone conduction driver subtly enhances the treble, adding a unique sense of depth and texture that makes the high frequencies feel rounded yet highly detailed. This nuanced integration avoids any noticeable roll-off, preserving excellent extension and ensuring no detail is lost.

Apevoix has impressed me with its balancing act here. The treble remains lively and engaging without overstepping into piercing or overly bright territory, making it an ideal choice for those who appreciate a crisp, well-executed upper range without sacrificing listening comfort. It's an impressive feat of tuning that adds to the Grit’s technical credibility.

Bone Conduction Driver

The inclusion of a 11mm bone conduction driver adds a subtle but noticeable layer of texture across the frequency spectrum. It doesn’t drastically alter the sound but provides a unique tactile quality, making each note feel more rounded and tangible. This innovation gives the Grit a distinct edge in terms of detail retrieval and realism and better more natural quality tone and timbre, even if the effect is understated.
Technical Performance:

Soundstage and Imaging

The Apevoix Grit offers a wide soundstage with impressive depth, creating an immersive listening environment. Instruments and vocals are neatly separated, and imaging is precise, allowing you to pinpoint the position of each element with ease. While it doesn’t quite match the holographic staging of the Dita Project M, it comes surprisingly close—a commendable achievement for a bassy, warm set and also in its price range.

Resolution and Dynamics

The Grit excels in detail retrieval, pulling subtle nuances from tracks with remarkable clarity. This level of resolution makes it a great choice for critical listening. Dynamics are equally impressive, with smooth transitions between quiet and loud passages, adding to the overall musicality.

Comparisons:

Binary Dynaquattro vs. Apevoix Grit

The Grit shares the Dynaquattro’s warm and detailed tuning but doesn’t quite reach the latter’s superior timbre and tonal balance. However, the Grit’s bone conduction driver introduces a unique tactile element that the Dynaquattro lacks.

Dita Project M vs. Apevoix Grit.

While the Dita Project M may have the edge when it comes to overall refinement, the Apevoix Grit holds its own with equally impressive imaging and detail retrieval. What sets the Grit apart is its ability to deliver this level of technical performance without leaning into brightness, offering a more forgiving and enjoyable listening experience. Considering its significantly lower price point, the Grit becomes a highly compelling alternative for those seeking high-end performance without the high-end cost.

Build Quality and Comfort

The Apevoix Grit’s build is solid, with a design that is durable and has a premium feel. However, size is a potential drawback to some. These are among the chunkiest IEMs I’ve encountered, protruding noticeably from the ears. The nozzle is deep-inserting and quite large, which could pose fit issues for users with smaller ear canals. While I personally found the fit secure and comfortable, it’s worth considering if you’ve struggled with similarly large IEMs like the Juzear Butterfly.

The nozzle of the Apevoix Grit, while having a larger diameter, also features a peculiar angle that affects its fit. To achieve maximum comfort, I found that I needed to tilt the IEMs slightly forward when wearing them—essentially positioning the connector around the 10 o’clock mark. This adjustment felt a bit unconventional at first but made a noticeable difference in comfort and fit.

It’s also worth addressing a comment I came across on Linsoul’s Apevoix page, where someone mentioned that the Grit has pressure build-up issues. Personally, I have to disagree. I’ve used my Apevoix Grit for extended listening sessions of 3-4 hours straight, and I haven’t experienced even the slightest hint of pressure build-up in my ears. Of course, everyone’s ears are different, but in my experience, the Grit has been perfectly comfortable and free of any such issues.

Using the included foam tips turned out to be the most comfortable option for me. They created an excellent seal, which not only improved isolation but also enhanced the overall sound quality. That said, fit is highly subjective and varies from person to person. With different ear shapes and preferences, what worked well for me might not be as effective for others. If you’re considering the Grit, experimenting with different tips and angles could make all the difference in your listening experience.

Who Should Buy the Apevoix Grit?

The Apevoix Grit is an excellent pick for those who crave a warm, powerful sound with beautifully textured and layered bass, lush, vocal-focused mids, and an engaging sound signature packed with detail and texture. Its tribrid driver configuration delivers a distinct listening experience, blending musicality with technical prowess in a way that punches well above its price range.

That said, its chunky design and large nozzle might not suit everyone. Achieving the right fit can be a challenge, but for those who manage it, the Grit proves to be a highly rewarding IEM. It’s an ideal choice for listeners who prioritize rich, immersive audio with a touch of innovation while being forgiving of its unique design quirks.

Final Thoughts:

The Apevoix Grit is an ambitious and innovative product that largely succeeds in its goals. Its rich midbass, articulate mids, and textured presentation make it a standout option in its category. While its size and nozzle design might deter some users, the sound quality and technical performance make it a worthwhile investment for those seeking something fresh and engaging. i would highly recommend the Grit specially those who enjoys the Binary Dynaquattry sound profile.
