Rose Technics QT-X Review: Kiss from a Rose

Rose Technics QT-X Review

Sometimes, you come across an IEM that just feels right—not tryin’ too hard to impress, not packed with gimmicks, just pure, well-tuned sound. That’s kinda what the Rose Technics QT-X is all about. When I first plugged these in, I wasn’t expectin’ anything crazy. But then, after a few tracks, I realized—this thing got some real character. The vocals sound rich and natural, instruments got space to breathe, and the overall balance just clicks. It ain’t overly warm, ain’t too clinical—just a smooth, detailed listen that keeps you hooked.

I tried this set with all of the sources I own. It definitely deserves some juice to open up its potential. And a warm kind of source can bring up some magic from it. I will talk about it in a different part of this review. And the stock accessories are also good and matched well with the IEM, especially the stock cable. The stock eartips are not that worthy, and you need to invest a bit extra for aftermarket eartips. I also will cover this later in this review.

UNBOXING EXPERIENCE

Unboxing the Rose Technics QT-X is kinda one of those moments where you don’t really know what to expect, but then it surprises you. The box itself? Pretty simple, nothing too fancy, but it got a clean, premium kinda vibe. Opening it up, you’re greeted with the IEMs sitting there, lookin’ all premium with that unique design. They got this glossy, almost glittery kinda faceplate that catches the light in a cool way. Feels solid too, not like some cheap plastic stuff. Underneath, you got the accessories—few sets of nerrow bore & wide bore eartips, a decently thick 2-pin cable, and a little carrying case. The case is actually nice, not just some throwaway pouch.

BUILD & DESIGN

The build is actually pretty solid. Soon as you pick it up, you can tell it ain’t some cheap plastic shell. The body got this kinda smooth, semi-gloss finish that feels nice in hand. It’s a bit on the bigger side, so not the most compact IEM out there, but it don’t feel bulky either. The design? That’s where it gets interesting. The faceplates got this almost shimmery, glittery kinda texture that catches light in a real cool way. It’s subtle, not all flashy, but got that premium kinda touch. And the shape? Feels ergonomic enough, though if you got small ears, might take a bit to find that perfect fit.

The connectors are 2-pin, which is nice ‘cause you can swap cables easy. Speaking of the stock cable, it’s actually decent—kinda soft, don’t tangle much, and looks clean. But yeah, if you wanna upgrade later, no problem. Overall, the QT-X got a well-built, stylish kinda look that definitely stands out without trying too hard. The diagonal carrying case is made of PU leather and looks really good. The supplied DAC is well-built with metal shell.

FIT & COMFORT

Well, that kinda depends on your ears. The shape is a bit on the bigger side, so if you got small ears, you might need to do some tip rolling to get that right fit. But once you find the right eartips, it sits in pretty snug. It’s got this smooth, rounded design that don’t poke or cause any weird pressure points. Weight-wise, it’s not super light, but also not heavy enough to make your ears feel tired after long sessions. You can definitely wear these for hours without too much discomfort. The nozzle ain’t too long either, so it don’t dig too deep, but still gives a secure fit.

One thing tho—if you move around a lot, the fit might shift a little, especially if you’re using stock tips. But with some foam or better silicone tips, it stays put better. So yeah, fit and comfort? Pretty good overall, just gotta take a little time to find what works best for you.

SOUND IMPRESSIONS

The QT-X is carefully tuned to have a natural, mid-centric sound character. The bass is impactful yet controlled and adds weight instead of overpowering other frequencies. In the midrange exists an equilibrium and definition that allows vocals and instruments to project and shine through. The treble is detailed and lively yet can appear slightly bright with neutral sets and when encountering badly mastered tracks.

Here is the frequency graph:

Let’s dive deep…

SUB-BASS

Alright, let’s talk about the sub-bass on the Rose Technics QT-X. First thing you notice? It’s got that deep rumble, but it ain’t over the top. It reaches low, gives you that nice presence without shaking your brain. If you like that clean kinda sub-bass that don’t overpower everything else, this one’s doing a good job. You can feel it in tracks with deep bass lines, but it ain’t like some bass-heavy IEMs that just go full blast.

Listening to something like “Royals” by Lorde, you can really hear that low-end thump sitting under the vocals, adding depth without muddying up the mids. It’s tight, controlled, and don’t bleed into the rest of the mix. But if you’re into super boosted, club-like bass, you might find it a bit polite.

Decay’s on point, don’t linger too long or feel slow. It got a bit of that natural roll-off at the lowest end, but still enough to keep things full. In bass-heavy EDM or hip-hop, it gives the track enough weight but keeps it clean. Ain’t no bloated mess here, just well-balanced sub-bass that does its job without stealing the show.

MID-BASS

It’s got that punch but stays in control—don’t go all crazy booming in your ears. It got enough weight to make bass guitars and drums sound full, but it ain’t the kinda bass that’s gonna shake your brain.

Now, play Every Breath You Take by The Police. That bassline, the one that just keeps rollin’ under Sting’s vocals, got that steady groove. On the QT-X, it comes through clear, got enough presence to feel natural but doesn’t overpower the rest of the instruments. The kick drum, too—it got a nice little thump, kinda soft but still noticeable.

What’s nice is, the mid-bass doesn’t mess with the mids. Sting’s voice stays clean, doesn’t get muddy, and the guitars still got their space. But if you want some extra warmth or thicker bass, might feel a little light, especially compared to bass-heavy IEMs. It’s more on the clean side, kinda polite, but still got that rhythm to keep the song feelin’ right.

VOCALS

When it comes to vocals, the Rose Technics QT-X does a pretty solid job. Male and female voices both got good presence, sittin’ naturally in the mix without feelin’ too pushed back or too in-your-face. There’s a bit of warmth in the mids, givin’ vocals some weight, but also enough clarity so they don’t sound dull or bloated.

MALE

So, right out the box, the QT-X got a kinda balanced tuning. Not too warm, not too cold. Male vocals don’t jump right at ya, but they also don’t feel lost in the mix. Some sets got that weird thing where vocals sound either too thin or too bloated—this one? It’s sittin’ somewhere in between. If you like that super up-front, in-your-face kinda presentation, you might find these a little too polite.

Now, if we take a track like “Smoke on the Water” by Deep Purple, you know you wanna feel that raw energy in Ian Gillan’s voice. His vocals got that natural raspiness, and the QT-X actually keeps it pretty well. There’s a bit of warmth in the mids, giving his voice some weight, but it ain’t overly thick or muddy. You can still hear that sharpness in his higher notes, especially when he pushes his voice harder in the chorus.

FEMALE

The QT-X got a slightly energetic upper midrange, which means female vocals get a nice bit of presence. They don’t sound too pushed forward, but they ain’t recessed either. It sound balanced, clear, and natural. There’s good detail, but it ain’t trying too hard to be ultra-clinical. If you love female vocal-driven tracks, these IEMs gonna give you an engaging, slightly energetic, but non-fatiguing experience.

Listening to “Fading Like a Flower” by Roxette, when Marie Fredriksson starts singing that first verse, you can immediately hear the details in her voice. The IEM captures that soft, almost whisper-like texture at the beginning without making it sound too thin or weak. And when she hits those high notes—“Every time you leave the room…”—you want that power and emotion to come through. There’s airiness, a bit of sparkle, but it doesn’t get harsh like some IEMs with aggressive tuning.

INSTRUMENTS SEPARATION

The instrument separation on the Rose Technics QT-X is pretty damn good. It’s one of those IEMs that lets you hear all the little details in a track without everything blending into a messy wall of sound. You know how some sets just throw all the instruments together, and you gotta really focus to pick things apart? Not the case here. Everything got its own space, and you can actually hear each layer without struggling.

Take “Bitter Sweet Symphony” by The Verve—a track packed with strings, drums, guitars, and vocals, all stacked on top of each other. On the QT-X, that iconic string intro sounds rich and spread out, instead of just sittin’ in the background like a blurry mess. As the song builds, the drums, bass, and guitars all stay clear and well-separated, so nothing overshadows anything else. Even when Richard Ashcroft’s vocals come in, they sit right in the mix without drowning out the instruments—which is exactly how it should be.

It ain’t the widest soundstage out there, but there’s enough depth that things don’t feel cramped. If you’re into tracks with a lot of layers, the QT-X lets you hear every instrument doin’ its own thing without losing the overall musicality.

TREBLE

The treble on the Rose Technics QT-X got a nice balance between being detailed and smooth. It’s got enough energy to bring out the finer details in a track, but it ain’t overly sharp or piercing. Some IEMs go too hard in the highs, making cymbals and high notes sound too harsh—QT-X avoids that, keepin’ things crisp but controlled.

Listening to “The Unforgiven II” by Metallica, you really get a sense of how well it handles treble. The acoustic guitar intro sounds clean and airy, with a good bit of shimmer but no annoying sharpness. When the electric guitars and cymbals come in, there’s enough bite to keep the track engaging, but it never turns into that harsh, fatiguing mess you get with some bright IEMs. James Hetfield’s vocals, especially when he pushes into the higher range, stay clear and natural, without any weird sibilance or sharp edges. Some sets can make the “S” and “T” sounds a bit too aggressive, but the QT-X keeps ‘em in check.

Overall, the treble here is detailed, slightly energetic, but not overdone. It’s got enough brightness to bring life into the music, but it won’t wreck your ears after a long listening session. If you like a bit of sparkle without harshness, the QT-X does it just right.

SOUNDSTAGE

The soundstage on the Rose Technics QT-X ain’t the biggest out there, but it’s got enough space to keep things from feelin’ too closed-in. It’s more of a natural, slightly intimate kind of presentation—not super wide like an open-back headphone, but also not too cramped like some IEMs that make everything sound like it’s coming from inside your head.

Listening to “This Is Goodbye” by Mark Knopfler (the live version from The Real Live RoadRunning), you can really tell how it handles space. The way the guitars, piano, and drums spread out feels realistic, with enough air between them so nothing sounds squished together. The vocals sit center, right where they should be, and the instruments feel positioned around them in a way that gives a good sense of depth.

One of the best parts? The way it catches the live atmosphere—you can hear that slight openness, the tiny echoes from the venue, and the way the instruments interact with the space. Some IEMs make live recordings feel too flat, but the QT-X keeps that sense of realism.

TECHNICALITIES

The technicalities on the Rose Technics QT-X are pretty solid. It’s got good dynamics, so soft and loud sounds feel natural, not flat. Speed is snappy too—fast drum hits, quick guitar riffs, everything stays clean without smearing. And when it comes to detail retrieval, it pulls out a lot of tiny nuances in vocals and instruments, but without makin’ the sound too dry or clinical. It’s a nice balance—detailed, but still musical.

DYNAMICS

The QT-X got some real punch when it comes to dynamics. It handles soft and loud parts really well, so music don’t feel flat or lifeless. You can hear the difference between a gentle strum on a guitar and a full-force power chord, or how a drum hit goes from a light tap to a hard slam with real impact. It ain’t overly aggressive, though—just enough to keep things exciting without soundin’ unnatural.

SPEED

Speed is one of its strong points. The drivers keep up with fast, complex tracks without smearing details. If you throw some fast double-kick drums or quick guitar shredding at it, the QT-X don’t struggle—each note stays clean and distinct. The bass is tight and controlled, not the slow, bloated kind that muddies up everything. For genres like metal, jazz, or electronic, this kinda speed is a big win.

ANALYTICS

The QT-X leans slightly toward the analytical side, but it ain’t too sterile or lifeless. It pulls out a lot of detail, so you can hear textures in vocals, subtle instrument layers, and even tiny background sounds in a mix. If you like pickin’ apart music and noticing little things you might’ve missed before, this set delivers. But it ain’t like those ultra-clinical IEMs that suck the soul outta music—there’s still plenty of warmth and musicality to keep things engaging.

SOURCES

Sources are very important for an IEM when it comes to powering up the set and the synergy. Without proper power, you will miss the perfect performance, and if your source doesn’t pair well with the set, you may lose the interest of listening to it. thought the good news is that these IEMs are versatile in terms of source compatibility.

POWER

The Rose Technics QT-X ain’t exactly a power hog, but it likes a bit of juice to sound its best. If you plug it straight into a phone or a weak laptop jack, it’ll play fine, but you might feel the bass ain’t punchy enough and the whole sound feels kinda flat. Now, throw it on a dongle DAC or a decent amp, and boom—bass gets tighter, mids open up, everything just sounds fuller. You don’t need some crazy desktop amp or anything, but a solid dongle with at least 1Vrms output does make a noticeable difference.

So yeah, it’s not super power-hungry, but it scales up nicely if you feed it a lil’ extra power. Basically, if you wanna hear it at its best, don’t just rely on a weak source—give it some proper power, and it’ll shine!

SYNERGY

This lil’ set is kinda picky—not crazy picky, but you can definitely hear differences depending on what you plug it into. To open it p a liitle, you need to plug it atleast a mid-tier DAC like Moondrop Dawn Pro or FiiO KA7 etc. If you use something with a warmer tuning like the iBasso DC04 Pro, the QT-X gets a bit more body in the mids and the treble smooths out a little. This helps if you find it too energetic sometimes.

With something like a Fosi Audio DS1 or Dunu DTC480, you get maximum detail. Treble gets a bit crispy, bass stays controlled, and overall it sounds fast and snappy. Throw it on a desktop amp like the xDuoo MT-604, KAEI TAP2 or xDuoo XD-05 Plus and yeah, it tightens up a bit more, but you don’t really need that much power. It’s more about refinement than raw power.

CABLE & TIP ROLLING

The supplied cable is a fantastic one and does perfect justice to the IEM. The single cristal OCC copper delivers the perfect tone of the set with a hint of warmth in it, though it comes with a 3.5mm single ended jack. For a 4.4mm balanced connection, I used NiceHCK MixPP & Dunu Lyra Mini, both are OCC cables and they do the same as the stock cable. The only difference is the extra dynamics due to the balanced output. And that’s not related to the cable itself, right?

The stock tips are not up to the mark in my opinion. I used them just for testing purposes, and they didn’t feel comfortable to me in longer listening sessions. I tried Spinfit W1, Omni, Dunu S&S, Candy, Epro propeller tips, Tangzu Sanchi, and DDhifi ST35, etc. To me the best pairing is the Epro propeller tips. They match very well with the sound signature of this IEM and deliver a fantastic, warm melodic tune.

BUNDLE DAC ‘RZ-300M’

The RZ-300m DAC comes bundled with the value pack of the Rose Technics QT-X, and let’s be real—most included DACs with IEM bundles don’t exactly scream high-end. So, the big question is: is the RZ-300m just a throw-in, or does it actually hold its own as a proper DAC?

BUILD & DESIGN

The RZ-300m looks really clean and minimul. It is a compact & light weight designed DAC that is easy to carry around. The metal casing feels sturdy, though the whole build quality feels a bit cheap in my point and may fall apart in daily wear & tear type of use. Comes with a USB-C connector attached with it, so it has a wide compatibility.

SOUND PERFORMANCE

For a bundled DAC, it actually performs better than expected. Equipped with CS4398 chip, the RZ-300m is a 24-bit DAC and support for 192 kHz PCM. It’s got a clean, neutral sound signature with a bit of extra energy in the upper mids and treble, which works well with the QT-X’s balanced tuning. Bass stays tight, with no noticeable bloating, and the treble is crisp without turning harsh.

One thing it does well is dynamics—soft and loud parts of a track actually feel distinct, rather than everything just playin’ at the same level. Detail retrieval is solid, but it ain’t the most high-res DAC out there. It does enough to bring out textures in vocals and instruments, but don’t expect it to compete with higher-end dongles like a iBasso DC04 Pro nor even the entry level Moondrop Dawn Pro.

POWER & COMPATIBILITY

With an output of around 75mW @ 32Ω, it’s enough for IEMs and easy-to-drive headphones, but don’t expect it to push power-hungry planar cans. The QT-X runs perfectly fine on it, but if you plan to use high-impedance headphones, you’re gonna need something beefier. No app, no gain settings, just plug and play—simple and effective.

If you already own a good DAC like the Fosi Audio DS1, Dunu DTC480, or Hidizs S8 Pro, this one won’t replace those. But for casual listening, it does the job well without any major complaints.

FINAL THOUGHTS

Alright, so the Rose Technics QT-X is definitely a well-tuned set. It’s got clear, detailed vocals, tight bass, and crisp but smooth treble, all wrapped up in a natural, slightly intimate soundstage. The technical performance is solid too—good speed, nice dynamics, and enough detail to keep things interesting.

It ain’t the kinda IEM that tries too hard to be ultra-clinical or overly colored. Instead, it balances musicality with technical precision, making it a great pick if you want something that sounds both engaging and refined. It’s not the widest-sounding set, but for what it does, it does it damn well.
