    Published Jun 24, 2019
    Pros - Balanced sound with great mids and surprising low area.
    - Separation, light, clarity, recreation, detail and richness of nuances.
    - Size and weight.
    - Accessories and cable.
    - "The whole is more than the sum of its parts.”
    Cons - Feeling of fragility.
    - Limited sound depth.
    - Sub-bass below 40Hz.

    Rose Technics is an established brand of IEMs and Earbuds. Its IEMs feature the hybrid technology used in most of them. Also their earbuds are very recognized and appreciated, among them the Masya and Masya Pro.

    The model I'm going to analyze is the second version of a series called Mini. This name is not trivial, as the dimensions of these hybrid IEMs are, and a lot. In this case, the Rose Mini2 MKII 2.0, are Dual BA. Surprisingly, they do not sound as analytical as one might think a priori, but even enjoy a certain warmth. Also, they are not so anemic in bass being a double BA of such a small size.

    The Rose Mini2 MKII 2.0 comes in a completely white box, with the brand in silver letters on the top. And nothing else. Just a small sticker on the side, indicating the model: "mini2". The box is square, 138x138x42mm. After opening it, you can see a metal can and round logo, brand and slogan. It is embedded in a foam mould. Next to it there is a small transparent plastic box containing tips of simple silicone and bi-flange. A 6.3mm plug adapter is located in a slot in the mould. Inside the metal box are the IEMs, with a silver-plated cable connected. In addition, it comes with a zipper bag with other transparent tips bi-flange, self-made and special, to improve the seal. Finally, there are two more pairs of foam tips in two sizes, in a bright red colour.

    All in all:

    • IEMs.
    • Silver-plated 4-core cable.
    • Metallic box.
    • 3 pairs of grey silicone tips in sizes SxMxL.
    • 1 pair of gray silicone tips bi-flange large size.
    • 4 pairs of specially designed bi-flange transparent silicone tips, sizes SxMxLxXL
    • 2 pairs of red foam tips, sizes MxL.

    I believe that both the presentation and the content are totally appropriate to the price level. A very simple and minimalist design, a very useful metal box, although I prefer semi-rigid with zipper. And some very interesting bi-flange tips. I just miss some tri-flange tips.

    Construction and Design

    The size of these lEMs are minuscule, they weigh nothing. The outer part of the capsule is greenish-yellow plastic. It is made up of two parts joined together. The nozzle is thin and covered with a metal cylinder. They do not have a grille to block the exit of the sound. The MMCX connection is at the bottom. At the top is the logo of the brand, in almost imperceptible relief. In the same way, but at the bottom, next to the nozzles, are the letters R and L, which identify each channel.

    They are so small that they give a sensation of fragility, perhaps the most negative point in this section. Even the plastic used in the capsules doesn't seem very rigid. In addition, the finish of the nozzles and its narrow channel, accentuate their union as a weak point.

    IEMs are not symmetrical, but have an inclination to improve insertion.

    The cable has 4 highly braided, silver-plated wire cores. This gives it high usability and flexibility, it is hardly binding and it is not microphonic at all. The sleeves of the MMCX connectors are silver-plated metal cylinders. A red ring on one of them distinguishes the side. The splitting part is made of transparent plastic, as is the adjusting ring. The sleeve of the Jack connector is cylindrical, with a bevelled side on which the mark is written. The 3.5mm plug is gold-plated.

    Nothing to argue about in the cable, very much in line with the IEMS.

    Adjustment and Ergonomics

    Given the triangular shape of the Mini2, its small size, the cable connected from below and the inclination of the capsules towards the channel, the adjustment is simple. Using the supplied tips, the sealing is increased, all the more so with the specially designed bi-flange tips. This is because the outer flange is larger, stiffer and more horizontal. In this way, the occlusion achieved is increased. The result is an almost perfect fit, a fairly high soundproofing and a good level of immersion. The only disadvantage is that there are no tri-flange tips of this type. Lately I'm getting the best results with this type of tips; having a deeper insertion, the clarity and closeness are enlarged.

    Although the Mini2 has an inclination to facilitate the adjustment in its corresponding ear, the use on the ear is possible, without the need to change the capsules on the side. In fact, it's the way I prefer to wear them, because with tri-flange tips, adjustment is easier even this way.

    Once put on, they don't move, as they don't weigh anything, the movement doesn't affect you. Even if you put them on your ear, tightening the cable under your chin, it's almost impossible for them to come off. In this sense, the adjustment is outstanding.

    A double BA could not show another profile that was not balanced. But that's not all, because it has warmth and brightness, as if its profile were a small V-shaped profile.

    Rose Mini2 MKII 2.0.png


    Out of prejudice: it won't be the best bass that a BA driver can produce, besides, being so small. But little can be criticized in excess the low zone of the Mini2. And I start with what could be a conclusion of the present range, but I do it in advance, because so it is.

    The bass, above all, stands out for its remarkable speed and dryness, but is neither cold nor hollow, but enjoys a fairly unexpected body. The sub-bass arrives more than decently at 20Hz, but I must mention that the sonority and the timbre of the frequencies below 40Hz are somewhat "special". But even that barrier, the naturalness of the bass is quite good.

    The mid bass is noteworthy for its linearity and good presence. There is a clear blow in this area, not overwhelming, far from it, but clearly perceptible and even moderately emphasized, if compared with the rest of frequencies. But, I am not going to deceive anyone, the lower zone does not possess the power, nor does it move the amount of air necessary to recreate the whole range with absolute authority. But it never ceases to amaze me more and more every time I listen.

    The texture is quite smooth, the shot is dry and concise, has some depth, but limited in volume. On the other hand the detail is good, but the lows are not very descriptive or dynamic.

    Rose Mini2 MKII 2.0 14_resize.jpg Rose Mini2 MKII 2.0 15_resize.jpg


    The lower-middle zone gently declines from the slight enhancement of the bass. Thus, this part is influenced by a faint warmth. And the voices benefit from it, apart from sounding more frontal, close and almost intimate, they have a soft and pleasant body. But they also have a fine spark of final brightness, which sometimes weakens the whole. The clarity is evident in all the area, in addition very well defined and conveniently filed in its final edges, to contain the profile, without reaching the surgical end. The mids remain in the delicacy and certain sweetness that brings warmth, to gain in naturalness, retaining the great detail and nuance that provides a well-tuned Balanced Armature of low and medium. The result is a BA that looks sweet and airy, that expands naturally and with more brio than one could have predicted. But, where the character of these IEMs comes out, is in the recreation of details and nuances, as it has an innate ability to reveal, with great richness, all the tiny musical aspects that have, both the bad recordings and the good ones.

    The treble begins very well with the mids, but suffers a brief high parenthesis after the first few measures, which reveals a somewhat conflictive point in a sensitive area. It is a double-edged sword, on the one hand awakened to a profile that until now was delicately contained and sweet. On the other hand, it moderately sharpens the highs in a single point, subtracting the good extension that it possesses. In this case, the average would have been more advisable than a higher note. In any case, this initial slight enhancement is perceived more due to the balance of the whole, than just by itself. And as many times happens, this hit sometimes appears, sometimes not. When it is not there, it is missed and when it is there, it is criticized.

    Overall, it is unfair to penalize both this small initial peak, because globally, the high points look as expected from a good BA dedicated to them: good accuracy, definition, finesse, with the crisp point indicated and with remarkable ability to bring air and clarity to the rest of the ranges.

    Soundstage, Separation

    The Mini2 soundstageis a bit particular, they enjoy a good width and height, because they offer a good opening and vertical projection sensation, but there is not much depth. The sound is open, but limited in distance. The amount of air and separation is great, causing an ethereal sensation, but without forming a cloud that surrounds the 360⁰, but rather a front dome, somewhat inclined on our forehead.

    It really is a pity that certain lack of depth, because the instrumental recreation, the existing separation between all the details and musical elements is praiseworthy. An improvement in this aspect would have provided a quite high level in this section. Even so, the light and space offered by the Mini2 is very good for its price, not within the reach of many IEMs in its range. It is another of the remarkable qualities of its BA drivers.

    Ikko OH1

    A priori it seems unfair to compare pure BA IEMS with other hybrids, but it may even be necessary to ponder the Mini2s fairly..

    The first difference noticed is in profile, the Ikko have a brighter profile, more unbalanced than the Rose. While the Mini2, are clearly warmer and more neutral, but with greater presence in the middle bass. The OH1 lead in the presence of sub-bass, weak point of the Rose, but, however, the Mini2 have greater presence in the whole of the lower zone, in their own way, of course. In this sense, their greater warmth plays an important role in this perception. The voices, in the Rose, also receive the beneficial treatment of warmth, to endow them with greater body and width, in addition to a closer and fuller presence. In the Ikko, the voices sound thinner, cooler, louder and turned towards the treble. Sometimes, even comparatively speaking, they become more crisp, just like the mid-range instruments, where timbre is perceived more sharp, due to the greater emphasis of the boundary between mids and highs. This is where the greatest equilibrium of Mini2 is found, and the incidence of its first highs is very reduced. But it also makes its light tenuous, since the Ikko shine more intensely, but it does not stop being an heady sleep, which reactivates that more intimate and attractive aspect of the Mini2.

    Already in the high zone, the Rose have more presence and extension. But the Ikko have a greater emphasis on the upper mids, which disguises the first highs of a more crisp and crunchy tone. But then, they become more trimmed, even going less far than the Rose trebles.

    The scene is clearly differentiated, the width of the Rose is vast, while the Ikko are perceived much more focused, with some greater depth. Although they don't really even win in that respect, it's just a feeling of disproportion between width and depth that the Rose have.

    In the Mini2, the width of their scene is largely due to the amount of air between their frequencies, so they enjoy greater separation. And although the Ikko sound very clear and with remarkable definition, their music does not expand as much as in the Mini2. As a result, instrumental recreation and stereophonic sensation are better described in the Rose than in the Ikko.

    I can think of two words to define the Rose Mini2 MKII 2.0: surprising and synergy. It's really commendable how IEMs with only two BAs drivers, inside tiny capsules, are able to generate such amount of sound and more with that quality. All the space and separation of the one that they do not have in their interior, is in their sound.

    The other big surprise is its low area, I still wipe my ears to check that it's true. And, on top of that, they have a certain warmth, not to mention their mids.

    Synergy comes because, this time, the sum of its parts improves the whole. Individually, my notes on the Mini2, in its various sections, are not excellent. But the final result touches it. The more time I spend with them, the better my overall evaluation is.

    Thus, the Mini2 has become my reference of IEMs with BA drivers. I just wonder how the Rose Mini3Pro will be with 3 drivers of this type, because with these I take off my hat, but I leave the Mini2 placed.

    ROSE Mini2 (MKII 2.0) — remarkable BA sound
    Written by IryxBRO
    Published Feb 11, 2019
    Pros - clear mids, good gentle treble, dynamic midbass, great instrument separation, very good fit, decent bass texturing
    Cons - bass is not that deep (which is totally fine for BA IEMs)
    Heard a lot of good stuff about ROSE Technics and their IEMs. Current lineup is quite big — 17 different models in $24 — $530 price range. Never had a chance to try either one until now — got ROSE Mini2 (MKII 2.0) version which is pure BA model with classical bullet-like shape and very small dimensions. I don’t have that much of experience with this type of IEMs and the only model that would be directly comparable is Earnine EN1J which didn’t become a huge revelation and based on single BA unit. Previous experience led to prejudice about single BA models in general and finally forced to believe that there would not be much too interesting about ROSE Mini2 MKII … And you know what? — all previous beliefs were wiped away with the potential enclosed in ROSE Mini2 MKii IEMs…


    ROSE Mini2 technical specifications:
    • BA driver: 2 Rose custom drivers
    • Frequency response: 20Hz — 30kHz
    • Impedance: 45Ω
    • Sensitivity: 108dB
    • Cable: 1.2m, silver-plated OFC, 3.5mm audio jack
    • IEM conectors: MMCX
    Also found this note in the desciption of Mini2 IEMs: ROSE Mini2 sound quality will not be fully reproduced by using with a mobile phone. Strongly suggest using HiFi player or better device :) Very funny and truthfull statement. I would say that every respected brand should write the same on their product boxes with large bold letters. There are people who would argue that some of the smartphones as LG would incorporate good DAC chips and so on.., guys: good DAP is not only anout DAC chip. Shielding, all supplementary HW element base, proprietary OS or tweaks to general OS, right ways of power supply — all matters and all influences the sound. Smartphones are not that good (yet) to catch up with good quality DAPs.


    Packaging, design and build:

    Didn’t expect to see so large package for so tiny IEMs wich is partially conditioned by the presence of quite big and durable storage case. Box is white, free of any prints except the brand name at front.


    Box contents:
    • ROSE Mini2 IEMs
    • audio cable with 3.5mm jack and MMCX connectors
    • 7 pairs of bi-flange eartips
    • 2 pairs of foam eartips
    • 3.5mm -> 6.6mm adapter
    • storage case

    Connecting gigantic 6.6mm adapter is funny — it is much bigger than IEMs. I hope that one day all brands would start to equip their bundles with the additional 2.5mm/4.4mm balanced jacks cables by default. This would also coincide with ROSE statement about using their IEMs with good DAP sources and getting the most of the potential reached.


    Mini2 IEMs are very tiny. So tiny that I had to change the lens on my camera to take micro shots.


    Shells are made of transparent plastic with rough surface. No gap between left and right parts is visible. Brand logo is printed on the outer sides.


    Despite the size, shells and all design elements look very accurate. Even such elements as L/R channel indicators are present.


    MMCX connectors are perpendicular to body and look pretty durable. No free play, very tight connector fit.


    Output nozzles are molded as a part of the shell and have the additional aluminum tubes over plastic base.


    Stock cable is 1.2m long, OFC, silver plated. Features aluminum housing of 3.5mm audio jack and MMCX connectors (right channel MMCX connector is identified by red plastic ring). Also has Y-splitter and limiter made of transparent plastic.


    At first there were some doubts about Mini2 fit due to peculiar MMCX connectors placement, absence of earguides and bullet-like shape. No problems in real life, though. IEMs are very lightweight and very comfortable to wear. Almost forgot that IEMs are still there after 2-5 minutes with music set on pause. Absence of earguides is not causing any troubles either — cable is soft and there is a possibility to hook it over the ear. Everything is perfect here…


    Sound quality:

    Tested with Hidizs AP80 DAP

    Lows and midbass:

    Yep, this section is the strangest part to describe for a person like me who would always tend towards hybrid or dynamic models with developed, deep and very extensive bass. Deep bass reach was always a bottleneck for balanced armature models in comparison to other types of IEMs. ROSE Mini2 MKII is not an exception but shows very good capabilities in a different manner. In contrary to dynamic drivers, where you would perceive the upper lows partially by hearing and deepest bass mostly by feeling, Mini2 plays through most of the sounds with decent texturing and dynamics and clearly defines bass instruments in overall. Extension would not recreate the portion that goes beyond the hearing abilities which is perfectly compensated by the amount of details that would draw off the attention towards the bass reach. The only shortcoming of that is that the bass is not that volumetric to widen the scene… In either case, lower end is evident, clear and textured, just a bit recessed and playing secondary role in the entire picture. One more word: understood how dramatic the influence on the lower end with the change to foam eartips could be. Of course, the extension would not improve but the lower end would be eleveated and get much better presence. Therefore, Mini2 MKII would benefit much from this combination and show even better results.

    Midbass is quite impressive considering the size of the shells and type of IEMs. Dynamics and articulation is more than enough, thanks to the fast armature. Drums are recreated pretty natural with the adequate (and not severe) touch of brightness infuenced by so mighty treble. At first, drums might sound a bit thin and lacking lowest registers but again — foam eartips do a good job on that.


    Mids and vocals:

    Mids are perceived as being located on the central layer of the stage — closer than lows and a bit behind the treble. Mids are exhibiting excellent resolution on instruments and voices. Moreover, very appealing part is that the sound is not that bright and crisp as you would expect from pure armature but much closer to Knowles drivers with kind of mellow nature. This would make IEMs more universal for large audience including people that are sensitive to lower treble. Vocals, no matter male or female, have natural and exposed presentation, good body and don’t tend to shout or hide behind the instruments. Harsh peaks on female voices are not evident, lisping is mostly polished by mellow feel. The most impressing here is the instrument separation leading to perfectly defined boudaries and letting you hear every single sound playing at its precise location. This also helps the scene to expand in depth.



    As expected from good BA IEMs — treble is decent and adequately accented. It is crisp and clear but at the same time not too biting and vivid to make your ears bleed. Extension is quite good but the most of the resolving power is concentrated on delivering accurate lower treble to aid the sound with enough transparency and feel of air. Sharpness is not excessive, all sounds are quite thick what also reminds of Knowles drivers. So, five starts go to ROSE for the development of their own BA drivers that would not fall short of expectations when it comes to a person mostly admiring the units from famous vendor. Love how Mini2 MKII treble performs: not severely bright and biting but perfectly exposing its armature nature.



    Soundstage is a bit controversial: width is not that great due to lack of deep bass extension but at the same time depth and vertical domain are quite good. Both are defined by decent layering of frequency ranges and great instrument separation together with clear and elevetaed treble.


    Sound in overall:

    ROSE Mini2 MKII sound could be described as moderately bright, accurate and very detailed. Presence of treble is adequate, not piercing or distrubing. Mids exhibit pleasing mellow effect. Lower end is recessed, perfectly textured although playing the socondary role and mostly located on the backstage. Lows are influenced much by the choice of eartips.

    Compared to Earnine EN1J:


    Earnine EN1J IEMs are based on single balanced armature driver and have similar perfect fit. Soundwise, not that impressive as ROSE Mini2 MKII due to less treble extension, mostly mids-oriented tuning and more shallow reach on the lower end. Resolution is quite equal between the two and the strongest part of Earnine in this comparison is the ability to reproduce midbass with more thickness to its body. But I would say that ROSE IEMs are more universal for any type of music genre.



    Really impressed with the performance of ROSE Mini2 MKII IEMs. Didn’t expect that detailed and weighted mids, accurate and thick treble, rich bass texturing, dynamic midbass reproduction and decent instrument separation. There were multiple attempts to look at its price while writing this review — constantly thought of a higher tag in conjunction to this level of sound quality. Surprisingly, price is more than adequate making Mini2 IEMs a great choice to deal with from the very beginning in order to understand ROSE BA nature which is capable of revealing most of the inherent potential.
