At this stage, KBEAR needs no introduction. But let's do a bit of history. KBEAR is a headphone brand from Shenzhen Lingyin Technology Co., China. It was founded in 2014 in Shenzhen, by a passionate and individualized young team, committed to developing fashionable and sound quality HIFI products for global audiophiles. As a dynamic and innovative brand, it is always on the move and this leads to a handful of new models every year. This time, KBEAR returns to a range of affordable and specialised models. We are talking about the new Rosefinch, an IEMS that combines a traditional capsule design for the brand, together with a more bassist profile, which may be very appreciated by many followers. But let's take a closer look at this model in the following review.

The KBEAR Rosefinch comes in a small classic packaging, with dimensions 75x103x36mm. The box is rectangular and its position is vertical. It is eminently white and on its main side there is a drawing of what could be bird feathers, in shades of red. In the centre, on the right, the name of the model can be read under Chinese characters. At the top right is the brand name. Behind it are the model specifications in Chinese and English. At the bottom are the brand's contact details. The wrap-around cardboard slides vertically, revealing a transparent plastic cover that protects the product. Underneath is a white cardboard-lined mould containing the two Rosefinch capsules above the brand logo, written in black letters. Under this layer are the rest of the accessories. In a nutshell:

  • The two KBEAR Rosefinch capsules, with a set of medium tips.
  • 1 set of grey translucent tips, sizes SxMxL.
  • 1 four-strand OFC cable.
  • 1 instruction manual.

Little else. The packaging is small and the accessories are at a minimum. There is not even a carrying bag, let alone the zippered case of the past.

KBear Rosefinch 05_r.jpgKBear Rosefinch 06_r.jpg

Construction and Design

The Rosefinch capsules repeat the design of other models of the brand, changing the motif of the outer plate. The outer plate is laser engraved and made of aviation-grade zinc alloy. It has a zig-zag pattern of rectangular elements, inside which is dark red paint. The brand logo is engraved at the apex of the outer face. The rest of the capsule is made of transparent polycarbonate.
The driver used is a 10mm dynamic driver with a biological diaphragm made of 5 micron silicone.
The inner side is made of transparent resin, revealing the interior and the drivers. There are two holes on this side, one coincides with the centre of the DD and the other is located further to the edge. On this edge, the rectangular 2-pin connection plate is placed superficially. It is a small piece of transparent plastic. On the same edge, but on the other side of the adjoining vertex, the name of the model and the letter indicating the channel are written in white letters. The mouthpieces are metallic and gold-plated. They have a height of approximately 6 mm, an equal maximum diameter and a smaller diameter of 5 mm. It is covered by a dense, ultra-thin, white grid of microscopic holes. As you can see, the nozzles are thick, but of a very adequate length.
It is an effective and durable design. Although it is repetitive, it is good, beautiful and cheap. Again, the maxim "successful model, don't touch it", or "if something works, why change it" is true. I think that reducing costs on the one hand can be reflected in improving other parts, in this case, I think that the beneficiary can be the driver used.
As for the cable, it is a dark copper braid of four OFC strands, each consisting of 18 0.05mm wires. The cable is relatively thin and seems the least valuable part of the assembly: the connector sleeves are black plastic, as are the splitter and pin, the shapes of which are very common and seen on cables in much more affordable products. The common part of the cable is thin, but this feeling is accentuated by the two-wire splitter at each capsule. It has a relatively stiff over-ear coating. The 3.5mm connector is gold-plated and its sleeve is 90° angled, but it is also made of black plastic, matching the rest of the cable. The dark copper colour, the plastic parts and the design make the cable feel very basic, just for transmission purposes.

Adjustment and Ergonomics

Little can be added to a design that I know and have tried before, with a more than remarkable performance. The size and the classic appearance of the capsules, with a semi-custom external shape, with a very rounded interior and no edges or corners, provides a superficial fit, quite free of contact with the external parts of the ear. And, if it does exist, the friction is very soft, due to the smoothness of the material used. This means that, as the hours go by, it does not affect the perception of comfort provided by this model. Thus, the ergonomics are high and quite good. Once fitted, there is hardly any possibility of rotation and, with the right tips, there is no risk of the IEMS becoming detached or falling out. In this respect, due to the 6mm diameter of the mouthpiece, the channel of the tips used must be taken into account, in case of changing them.
The size of the capsules is not very large, although they are a bit fat. Their weight is not heavy, but I would say that the metal plate is noticeable. However, once they are in place, this weight is negligible and hardly noticeable.
With my silicone tips, filled with foam, although the fit is quite shallow, the sealing is very adequate and the insulation level is high. But due to the length of the mouthpieces, narrower tips could be used to achieve a deeper insertion, although the diameter may prevent this process in narrow ear canals.

KBear Rosefinch 09_r.jpgKBear Rosefinch 10_r.jpg



The Kbear Rosefinch has a W-decreasing tuning, where the sub-bass is the highest part of the profile. The low end is warm, slightly dark, thick and has a medium velocity. The mids have a descent that approaches 1Khz, which means a very progressive drop, something that affects the first half of the mids to have enough body to be present, but maintain that thickness typical of the bass. From here, the rise in emphasis is just as polite and the mid-highs remain gentle, just enough to add a gain of bell to provide clarity and some light, but without overpowering or breaking the overall warm character. The treble begins with a slight control zone, followed by a sparkle that is typical of other Kbear's, which serves to enliven the zone and achieve some extension, which then relaxes into the air zone.

Kbear has kept the Rosefinch from being a niche bass-head IEMS. Undoubtedly, the predominant band is the lower band, but its focus on the sub-bass, only slightly stretched towards the mid-bass, prevents it from sounding too muddy or rubbery. Admittedly, the bass is thick and that adds elasticity to the punch, describing the area with medium speed. Still, the great abyssal depth of the bass ensemble makes the area enjoyable, even when the music is focused on this section. The Rosefinchs don't flinch and are still able to show off with authority, respecting voices and treble. At no point do the basses become an abomination that swallows up the rest of the music, not at all. Thus, although the weight and body of the bass is very great, the rest of the range shines within the subdued darkness of the Rosefinch profile. Another good quality of these IEMS is that they scale quite well when the source is of good quality. At this point the bass is able to sound contained, drier, richer, gaining in texture and descriptive power. These are certainly qualities that the Rosefinch treasures and it is not just expensive IEMS that need to be connected to exceptional sources. This is how you can enjoy a sensory subwoofer loaded with tension and a remarkable sound pressure, as well as assuming a good stratification knowing how to differentiate between layers and bass lines, without reaching saturation, even maintaining a quite acceptable agility. Very remarkable for the price and its profile. The negative point is a combination with badly recorded and uncontrolled bass, this is where the Rosefinch can suffer.

KBear Rosefinch 11_r.jpgKBear Rosefinch 12_r.jpg


If you isolate the midrange in itself, you will notice that the tuning is very adequate, well-drawn, measured and balanced. It is true that coming from such a high sub-bass, it might seem that the mids would be too far away, but this is not the case. You only have to cover the range below 200Hz with your left hand, in the frequency response curve, to realise what I am talking about. The result is obvious and my ears describe a warm, yet clear mid-range, with an important physicality in the first half, without sounding boxy, muddy or hollow. The Rosefinch know how to dodge these bad sonorities, though it can't get rid of the thickness and a certain darkness coming from below. In this way, the male voices feel quite powerful, very full-bodied, dense, perhaps a little exaggerated in this sense of fullness. The base is big, that thickness is characteristic and also irremediable. This is how warmth is represented in a very open way in this first phase of the mids. These attributes also stick to the strings and keyboards, it is easy to notice their width avoiding a more propitious agility. It is not a slow sound, but its density seems to prevent it from moving, as if it were a sea of mercury. Even so, the sound is quite melodious and with more than acceptable dynamics. The guitars will not sound very sharp, but the bass will be predominant and physical. It is clear that this environment is not the best for details to be sparkling or splashy. The Rosefinch are on the soft side in this regard. Thus, the female vocals can come to sound a bit more subdued, also because the high-mids are well controlled. A little more light is missed, but to conjugate a more excited area at this point, together with an unashamedly warm profile, would have been a mistake and a clear tonal mismatch. So I prefer this more typical, autumnal coherence, rather than a meaningless seesaw, just to compensate. The result is a sound devoid of sibilance, but drier than usual, with a controlled attack, slightly lacking in delicacy, but remarkable for the relaxed, romantic and sweet side. A different point of view, but very acceptable and enjoyable.

KBear Rosefinch 13_r.jpgKBear Rosefinch 14_r.jpg


The high end is totally in keeping with the character of the Rosefinch. I could say that it has a certain sonority of more classical earbuds. That is, a softly excited first part, with a good initial performance. This is followed by a restrained control zone, ending in a nice light punch that is lost before reaching the air zone. It is an inoffensive treble, which fulfils its role in a realistic representation of the sound, albeit with a nuanced tone, very soft and polite sparkle. The secondary emancipation is not enough to provide superior brilliance, although it does enable some clarity, sharpness and a pleasant and appreciable sparkle, especially for adding harmonics to the midrange. It is not a crystalline zone, nor is there a struggle between darkness. It is a dim, warm light, which does not lose its sharpness, although a greater amount of air and extension is lacking.

KBear Rosefinch 15_r.jpgKBear Rosefinch 16_r.jpg

Soundstage, Separation

The most remarkable thing about the Rosefinch stage is the depth, observing the range of their LFOs. This generates a u-shaped stage, with a more than acceptable laterality, which avoids a congested or too centred sound. It is a more than adequate stage, good even, without too much height, but with a nice stereo feeling and a point of gaseous volatility due to that depth.
There is not much of a sense of air and separation is not a strong point either, due to the thickness of the notes and also their greater elasticity. Technically acceptable, the details are not remarkable, but neither is the sound blunt or highly nuanced, but its level of sharpness and warm exposure favour a sound that is more musical and sweet, rather than delicate or fine.

KBear Rosefinch 17_r.jpg


Kbear is still committed to establishing a line to follow within its affordable range, maintaining a design that complies very well as an effective, comfortable, light, ergonomic and very well accepted standard. On the one hand, it cuts costs with a basic cable and packaging. On the other, it takes a chance on a more specialised profile, which boosts the low end, but without losing sight of the mids. This is a warm, almost L-tuning, with a hint of darkness, where the treble is smooth, maintaining an initial sparkle. The mid-range starts with plenty of body and a thickness that creeps up from the lows. Then, the mid-highs are pleasant, balanced and coherent, completing a powerful profile in the sub-bass, gaining smoothness and musicality, as the frequencies advance, without losing the sharpness in sight.

KBear Rosefinch Review

KBear has been on quite a tear of late. A lot of praise has been given to many of their new releases. One of the newer KBear budget iems is the KBear Rosefinch which I will be reviewing today. This will be a quick look review to showcase a fun sounding set with voluptuous bass and a warm and rich tone to it.
Also, I want to thank KBear for sending me the Rosefinch with the understanding that I would provide a fair and honest review. I put my integrity over any company and would never write a word that isn’t my authentic feelings. Just let the reviews fly and where the dust settles…it is what it is. I congratulate any audio brand willing to put their product on the line. That means they trust their product and stand by it. It means that they believe in their product and are excited to get it out into people’s hands.

Last in the Bird Line?

The Rosefinch seems to be in the “Lark” line of iems for KBear. Each of the iems in this line are named after different song birds. They all take on the same shape, for the most part and each have a slightly decorated faceplate to make the distinction between them all. The Lark was a set that I did not totally agree with but had many people who liked the balanced and more neutral tuning. Similar to the Lark, there was the Robin and finally the Rosefinch. Let’s take a quick look at this more thick & bassy iteration of this iem series.

Check out Mahir’s review of the Rosefinch here: Mahir’s Rosefinch Review

Not much to report here. You get the regular small rectangular white box with a graphic designed picture of what appears to be Rosefinch feathers. The look is actually very catchy and classy, not a bad design. Opening the box, you are met with the earphones themselves sitting in foam/cardboard cut-outs. Underneath the Iems is the ear tips (#4 in total) wrapped in a white little plastic baggy. Also, you’ll find the cable wrapped up as well. No case is present, but I really wasn’t expecting one.




The eartips which come packaged are gray in color with a more narrow bore. You do get four pairs in total. They are decent quality though I would likely tip roll to some wider bore tips for this set. However this review is done using the included tips.

The cable is the same ole KBear tightly wound brown cable. It is a four core silver plated OFC cable of decent quality. It’s usable and that is a good thing though I may also cable roll this set. The included cable is a 2-pin cable which terminates with a 3.5 SE right angle jack.


The build quality is nice. The resin or plastic body is of durable material while the Zinc Alloy Faceplate adds a class touch to the look of this set. The Faceplate is partially adorned with Rosefinch colored crisscrossed lines and I like the design. There is something nice about a minimalist look. The nozzle is a brass type of nozzle with a nice lip on the end Very much in the style of the Lark as well as the Robin. The build is nice for the price. The semi-transparent shell easily shows off the driver inside, as you can see in the pictures below and I always think that is a nice touch.

You can easily see the Internal Driver on the Rosefinch


Internally we are looking at a single 10mm Silicone Composite Biological Diaphragm Driver. As I said, the driver is easily visible through the shell of the Rosefinch. Not much else to say about that.

I hate to even add “Fit” as it is one of more subjective attributes to an earphone. However, I do get a great seal and nice fitment personally. Just like the Lark, these sit perfectly in my ear. The nice fit gives pretty good isolation from outside noise. I have zero idea how it would fit anyone other than myself and my dog. By the way, these don’t fit my dog. They do however sit nicely in my ear while resting just past flush with the outside of my ear. This is one of those categories that doesnt really make any sense to report on. Oddly enough it is one of the questions I always get asked.



The Rosefinch is meant to be driven from most any source and I can concur. I could easily drive this set from lower powered dongle dacs such as the Zooaux Dac. I used the IFi Go Blu the most using LDAC through my Galaxy Z Fold 4 and I like this pairing a lot. Doing chores through the house was nice.

I used the Ibasso Dx240 quite a bit as well and did not have to use anything higher than low or medium gain. I did prefer a bit more power at medium gain as it beefed up the dynamics a bit. Using the Fiio KA3 was nice as it caters more towards the neutral side of the scale. I do think you would be better off with a closer to neutral source to counter the warmer tonality of the Rosefinch.

All in all, the Rosefinch is easy to drive. Either from a phone, dongle dac or dap is perfectly fine and easily suits this set. Perhaps a more neutral source would be a bit better of an offset with the Rosefinch’s warmer tonality.


Sound Impressions

The Rosefinch represents a more V-shaped tonal character with a hugely elevated low end, a recession in the Midrange and a small rise in the upper half of the frequency. The Rosefinch keeps a warm tonality throughout and doesn’t really deviate at all. The sound is smooth and bassy yet clean enough for a low-cost V-shaped iem. Granted these won’t garner any praise for their technicalities. Still, they aren’t the worst in this regard.

Also, if anyone reading this is thinking of purchasing this set for its technical abilities? Maybe you’re thinking that the Rosefinch sounds anything remotely close to the Lark? I’d probably stop you right there. The Rosefinch is the polar opposite of the Lark. This is an easy sound, smooth, fun and warm all the way through. I like that the Rosefinch is exactly what it was created to be and no confusion about what that is. The Rosefinch is without a doubt a banger of a bass-head budget iem.



This is a big boys bass! We aren’t talking any chump bass here. This is a man’s bass! Or… a lady who enjoys bass… eh let’s just forget that last sentence. The point is, the bass is big, elevated, juddering to the core and very atmospheric. The bass is king here, as it has a big presence. The low-end most assuredly bleeds over into the midrange adding heft & gusto to male vocals. Also, resolution is not horrible considering how elevated the low-end actually is. Granted, clarity and resolution take an immediate hit with such a boost. However, relative to the size of the bass the Rosefinch has decent resolution for a budget bass banger. I should also ass that relative to the size of the bass the speed of the low-end is not all together slow which is nice to hear.

Some will call this muddy, and they aren’t wrong. That just goes with the territory and is a testament to the subjective nature of the hobby. I think of this set in Bass-head terms. I am not judging the Rosefinch in a balanced audiophile standard. That would be a clear mistake. Also, why would anyone judge this set as such when clearly this is made for the masses. This is meant for fans of Hip-hop, EDM, R&B etc. etc. and for those who love a big thump of low end.


The sub-bass is thick, it’s deep, it rumbles, and it vibrates. It has that tangible feedback that bass heads much like my former self, and even current self seems to yearn for in my music at times. Pop on any heavy sub-bass track and you’ll get it. Nuff-said. This is most definitely a sub-bass focused low-end and it comes with all the low hitting feels. Texture is evident and clarity is not completely lost. For a budget Bass-head iem this set is pretty darn well done.


The Mid-bass is no slouch either. There is plenty of slam in this area. It is a softer bass in terms of note edge, but it’s heavy. I’d call it blunted a bit, but it has so much raw force. The mid bass is slower to decay and sustain does linger a bit as well, but it has that atmospheric resonance to carry certain genres. Not everyone wants some speedy and snappy bass all the time. Truthfully the Rosefinch brings me back to my youth. When I listen to this set, I almost see my young punk self, seat leaned way back, window cracked and the volume up while I’m bumping down the road. There is simply a fullness and depth to a bass drop. Even now I can hear the screws rattling on my Chevy Truck.

All in all, it’s not the most technical low-ends. Separation isn’t completely lacking between the two bass regions, but it also won’t get any trophies for its separation & layering abilities. There is decent resolution here and that is a good thing. For a budget iem to be so focused on one area of the mix having a driver capable enough to not become a mudd-stuck mess is great for the target audience as the Rosefinch plays to a very specific demographic but can also venture out into other genres…sparingly. Edges of notes are a bit softened as it isn’t the most crisp or cleanly rounded. I say “softened” loosley because thier is a rotund and deep nature which makes up for the soft outline. The low-end is deep and it booms and definitely hits the basshead mark for me.

The Rosefinch has a tightly wound cable



The midrange is certainly pushed back a bit. Recessed in most of the midrange. There is a definite spill-over from the low-end here as well. The carry-over from the low-end brings weight to instruments and male vocals which is normally a plus. Weight is one thing, but clarity and resolution take a major hit in this area. Now if this set is catered and targeted at Bass-heads and Bass-heads alone who couldn’t care less about what lies past the mid-bass then… it’s a gem of a set. However, listening to the Rosefinch there is an undeniably restrained lower midrange.


Females actually have decent energy considering the veil but without any real shimmer. They are emphasized over the rest of the Mids but aren’t sparkly at all. They sound just fine and truthfully are the saving grace to the rest of the spectrum. Females are full in voice and emotional with softer note ends and a smooth sound. The inherent texture to a woman’s voice seems to be lacking a hair with a smoothed over and softer delivery.

The veil thins out a bit here and some clarity can start to peak through in the upper midrange. This area is completely non-fatiguing and not at all sibilant. It is an acquired taste for many however, or a particular taste for some. I will repeat what I said earlier though, if you are a bass junky who only cares about the boom and slam then this may be a good iem for you.

Not for the audiophiles

The mids are what I thought they’d be, and I’m not dissatisfied. I know what this set is and If I thought they were tuned to be some ultra-clean and clear and very resolving midrange I certainly would be disappointed. This is a fun iem which looks at the audiophile with a confident smirk, shakes its head and rolls its eyes. This set is not for them.



The treble region is not very heightened in terms of the total replay of the Rosefinch, but it is well enough extended into the air regions. The overcast theme continues into the treble, however. Cymbals do have decent body to them without sounding shishy and tisky. Instead, they have a nice ‘chisk’ to the sound while rendered a bit further back. Resolution and clarity are sub-par overall.

This treble will not brighten the mix too much or add that much coolness to an overall warm sounding set. It does make a showing though and information can just be heard in the air region. It sounds as though there is a steep roll off somewhere past the Mid-treble. Details are a bit more muted in the whole of the treble region yet still aren’t completely lost to the veil and warmth. I can still very easily make out surface level details and that is all a set like this needs.

What you can expect from the treble

Like I said, this is not the most detailed or separated or even polished treble, but I also think we all expected as much. What you can expect is a very smooth and easy going sound which is devoid of any harshness or peaks. You won’t find a hint of sibilance either which is always welcome.

If it were me and for my ears, I would ask for a bump up top but not everything in life is catered to good ole’ me. The target demo of the Rosefinch seems to be younger people who want to bob their heads and who prefer their eyeballs to rattle. They aren’t sitting in a quiet room critically listening. Nah, those kids laugh at the thought of that. Give em’ some Bass!!




The stage of the Rosefinch is not as bad as I would’ve suspected. I would’ve thought a bass region this big would draw in the stage but in truth the stage isn’t half bad. Obviously, this is not some cavernous stadium but there is some average height and even average depth. The width is narrower to my ears.


The separation of instruments and elements of the stage aren’t a complete mess but also won’t thrill the technical junkies. What can I say, separation is not the best. There is a bit of blending of sounds at times.


The psycho acoustic imagery presented leaves instruments and voices positioned okay. Still, congested tracks will sound congested and blur the stage. Imaging is not the strong suit of the Rosefinch yet I still wouldn’t call its imaging bad. I’d say the Rosefinch is about as good as it can be per the tuning and per the price tag.


This is not a detail-oriented budget iem. I think we’ve established this so far in this review. Yet details aren’t completely absent. Like I said earlier, surface level clarity and resolution are fine to bring out some details. There is a roll-off up top and a prevailing warmth which certainly doesn’t aid in a detailed playback. Again, if you are purchasing this set thinking it’ll align with the Lark where details are concerned, I would probably point you elsewhere. Most people who are searching for reviews and wondering about the Rosefinch probably know what they are getting. Still, details aren’t completely lacking.

Left to Right: 7Hz Salnotes Zero / KBear Rosefinch / CCA Lyra


*Note: I realize these two comparisons couldn’t be further from the tuning of the Rosefinch. Still, they are within the price point and I am using them more as tools to show distinctions. This isn’t a competition to find which is better.

CCA Lyra ($21)​


The Lyra is one of those special budget sets which sort of re-define standards to an extent. To be quite frank, the Lyra are outstanding in my opinion. I don’t compare iems to pursue which one is better. I am not intending to crown one set against another as it is more helpful for me to point out the alterity and distinctions between sets to help understand what they sound like. A theme which plays out in all my review comparisons.

The Lyra is a single dynamic driver iem within the ultra-budget segment of KZ/CCA’s lineup. They have created some fantastic single dynamic earphones of late and this is obviously no exception.

The Rosefinch has a much heftier and more extended low-end with a response that shudders compared to the Lyra. The Lyra have a more finesse bass region which has a bit more speed. I would never claim the Lyra is absent of bass, as it is actually the contrary. The CCA Lyra has a quality bass over quantity. The Rosefinch are exactly what I have spelled out in the entirety of this review…a Bass-head set, bass cannon, big boi bass.

The Rosefinch has a warmer presentation and a more dialed back midrange. The Lyra on the other hand have a more upfront and resolute sound here. The Lyra sound cleaner and have tactile texture and a cleaner leading edge. Lyra is more controlled and confident sounding to me. Vocals sound more natural as well. That said, the Rosefinch have a heft in note weight and a smoothness that the Lyra cannot duplicate. The Rosefinch has a more smooth but veiled sound while the Lyra has a more snappy and clean sound.

The treble region of the Lyra extends seemingly further. The sound is brighter and more resilient sounding on the Lyra. Lyra is more detailed and technically better all together. Still the Lyra also has a chance to fatigue much easier as the Rosefinch is much smoother and easier on the ears.

Stage size is bigger with more depth on the Lyra. Again, details come through much better and the sound is more natural as well on the Lyra. The Rosefinch has that deep and pulsating slam in the bass region which can be infectious if that is what you are after. Also, the Rosefinch is so easy to take for long periods of time. Truthfully if a balanced sound which has good representation from all areas of the spectrum is what you are after then the Lyra is the one to go for. Again, if basshead is what you are after… look no further than the Rosefinch.

7Hz Salnotes Zero ($21)​


The Zero is an ultra-budget offering with a single Dynamic Driver. 7hz went with a 10mm Metal Composite Diaphragm within the simplistic but sleek shells of the Zero. We have seen huge love for this set and by all metrics the praise is justified.

I will keep this quick. There is no comparison here. These two couldn’t be further apart in sound signature. The Zero is an ultra-clear and has a clean & balanced replay which borders on neutral and is simply beautiful for the price. The Rosefinch, on the other hand is very warm and rich and inviting and perfect for long listening sessions.

Bass on the finch is slower but much more elevated and hits harder by a country mile. The Zero sounds tight, concise, speedy and doesn’t even try to affect the midrange. Slam is there on the Zero but muted quite a lot in comparison.

The mids on the Zero are thinner than they are thick and come across more natural to my ears. Female vocals sound spirited with more shimmer, and males are thinner than on the Rosefinch but they are edgy and clear and resolute. The Rosefinch has a more veiled sound in the midrange but still has decent vocals with the thick timbre in males and females. Again, I hear the Zero being truer to life to my ears.

The Zero’s treble region has a much cooler atmosphere with a bigger emphasis in the upper areas of the mix. Though the extension sounds about the same with info into the air region on both sets. I should add that the treble on the Zero is much more concise and controlled and easily picks up smaller details. Again, the Rosefinch has its common repeating theme of smooth, thick and easy.

All in all, I would pick the Zero 10 out of 10 times for a more diverse library and if I want a more balanced and detail-oriented sound. But if I want that big bass that I want to feel as well as hear….10 out of 10 times I’d go with the Rosefinch. This is how contrasting these two iems are to one another. I like both the Rosefinch and the Zero for different reasons and different purposes. Both of these iems excel in their own ways.



Great job KBear! You set out to create a fun iem that doesn’t break the bank, that looks cool, is an absolute beast of a bass cannon and one which anyone could listen to for hours. Unless of course you are allergic to bass, if that’s you, well… I cannot relate even a little bit. Give me that bass! Thump the eyelashes off my face and tickle my ears, vibrate my eyes while I bob my head. Did I go too far? Anyways, it’s an every once in a while indulgence for me when I need a departure from the constant barrage of Harman tuned or balanced sounding audiophile directed Yada, Yada, Yada. Sometimes I just like to THUMP! For that purpose, I have a budget set perfect for it… The KBear Rosefinch.

Thank You…

I want to thank anyone who chose to read this far into the review of the Rosefinch. I thank you for putting at least a small amount of trust in my opinion. Also, I again want to thank KBear for their generosity and willingness to give myself as well as the chance to review their product.

Well, that is it folks. Please take good care, God Bless and try to stay safe in this crazy world. So long.
