KB EAR is a new contender in the sub-50$ Chi-Fi market. I had the chance to try their Opal, which is one of various products they launched to start. Others (I have some and I will review them later) are the F1 (single balanced armature IEM) and an 8 core upgrade cable, but there are also a 16 core cable and a KZ-like 5 BA IEM. I want to thank KB EAR for this review sample.

Unboxing and first impressions

The box is simple but elegant, similar to the RevoNext QT5 or the BQEYZ BQ3 ones, in a black color with the logo, a picture and some information around its faces. There’s a good selection of soft silicon eartips (6 pairs) and a surprisingly good MMCX cable (for its build quality, less for the isolation). The IEMs themselves are all made of plastic, with a very nice design which reminds me some IBasso In Ear Monitors. The faceplate has a carbon look with the KB EAR logo on it. Impressive, good looking, even though I would have put a metallic nozzle. The quality of the plastic is high, and the MMCX connectors are gold-plated and the cable can rotate very easily when attached. The cable has pre-formed hooks to put over the ears, which are great, and the plug is L-shaped. With a carrying case, even a soft one like BQEYZ does, the package would have been spectacular.

I’ve previously mentioned some problems with the isolation. In fact, the cable suffers from electric noises by a disturbed source (like my Mac’s jack output, which is close to the hard drive). I’ll verify if their upgrade cable would resolve this problem, because my 8 core by NiceHCK doesn’t suffer from that issue, thanks to its great isolation. Speaking of which, the isolation of the IEMs themselves is just average: the shape is not particularly ergonomic, and if you have medium sized ears like me, you could have some air coming through a little bit too often. That being said, the fit is average and you can adjust it with the best tips for your ears, obviously.

I’m not fully convinced about the sound of the Opal. KB EAR told me to burn them in 72 hours. I’m not a true believer in burn-in, but I followed the suggestion, because this is a dynamic driver earphone. Even after the burn-in, I felt like they are not very lively. There’s a sense of unnaturalness that I believe it’s the sum of different factors: the soundstage is narrow; the tuning has to be improved, because it’s balanced but it sounds muddy in the low range and thin in the midrange; vocals are a bit harsh. I’m not saying they sound terrible, but there are some albums that I can’t listen to with them (“Urban Hymns” by The Verve, or “A Fever Dream” by Everything Everything). That last album is often hard to listen to with bright earphones. I would consider the Opal as bright sounding, they have some aspects of harshness and sharpness. For example, they are not gentle with the sibilance, nor they are not smooth sounding, in any way (“The bends” by Radiohead is unpleasant to listen to for the sibilance). The bass is undertone: by listening to the Bloody Beetroots’ “My name is Thunder”, the intro is enough to understand that the treble is super enhanced, while the bass is lacking. This aspect reflects the tuning in every song, so you can choose the Opal for bass-heavy tracks and not feel that bass (it reminds me the BRAINWAVZ KOEL, or the Tin HiFi T2/T2 Pro, they are pretty light on the bass). I’ve tried different sources with the Opal, to find the best synergy. I found that warmer sources are preferable, but here’s the thing: it’s easy to get a better sound if you use the iFi xDSD, but I don’t think that people interested in buying something like the Opal would spend that money for a DAC/Amp. We are talking of budget earphones, and it’s more honest thinking of a cheaper source like my Dodocool DA106 DAP. They match pretty well together, but you must understand the Opal are not surprisingly good, even with good files, even with good sources; they are just honest sounding for the price, not so natural, not so lively. Their sensitivity must be very high, because even with my Focusrite 2i2 I hear a lot of background noise, which is not something I’d expect (if you look at the specifications, it’s just slightly over the average 100 dB). Vocals are a bit robotic and lack harmonics, so the effect is hearing recessed mids, while they are not. Try with Radiohead’s “High and dry”, for example: the voice covers a large spectrum of the midrange to the high range, but here it sounds thin and unpleasant. Guitars are not the best, too. Percussions are more enjoyable. Then, if you listen to tracks that fade out you won’t hear a smooth volume change but some steps; I can say the same for the imaging: it’s pretty precise but not smooth, and the soundstage, while being narrow, is strangely uncentered, unbalanced. I hear more sounds on the left earphone, like the instruments were positioned that way. The instrument separation is average, not bad. I don’t understand the sound signature of these IEMs. For a dynamic driver, they have a ridiculous bass, but I think they are meant to be V-shaped. In the end, they are just close-to-flat-until-the-upper-midrange earphones with a lot of picks and notches in various zones, even in the midrange. I honestly never heard anything like that on “serious” earphones. It’s like they have problems with their polarity.  



ADVANCED Model 3: personally, a difficult earphone to appreciate initially, but now I understand its fun tuning and its darkness. True, they have recessed mids, they are not fantastic IEMs for vocals, but they are coherent. I’d rather them to the Opal, which have the only advantage of having a better stock cable. The fit, the packaging, the tips, the sound, everything is superior on the Model 3. Review here

TRN IM1: am I really comparing two disasters of monitors? Okay, I have two pairs of IM1, they sound terrible. Incoherent, thin, bright, muddy. Just like the Opal! I don’t want to be too brutal, the Opal are superior to the IM1 for me, but I cannot say I like them or even save them. Well, I don’t want to talk about these anymore. Review here

KZ ZSN: strange enough, this is one of the few times I can say that I’d rather a KZ to another earphone. The ZSN are good, surprisingly good for being a KZ. They sound balanced, with their expected U-shape and the color needed for a mass-oriented IEM. Here, again, I talk about coherence, because that’s the point that lacks the most in this review. I don’t hate sound signatures. I’m a flatness lover, but sometimes I need that bass. I’m not a fan of brightness because it’s usually a friend of harshness. But I can stand everything if I understand the will of the earphone. I don’t understand the will of KB EAR, with the Opal. We’ll see if the single BA (F1) by the same company is different. ZSN review here.



If I weren’t a reviewer, with all these earphones to try every day, I’d be way less critic about the Opal. They are not terrible, but the Chi-fi market nowadays is a sea full of sharks and you have to be careful before selling a product with an immature tuning. To be gentle, I’d say the Opal are not my cup of tea. I love their design, I like their cable, I appreciate the MMCX connectors, but in the end it’s the sound that matters, and this is not something I would recommend.

Unboxing and first impressions

Apart from certain models, Knowledge Zenith usually packs its earphones the same way. This one makes no exception: white box with earphones, three pairs of starline eartips plus a silicon medium pair already attached on the earbuds, some manuals and a cable. Luckily, this is a better cable rather than the ones I usually see on KZ models (like ZS3, ES4 or ZS7), because it doesn’t have that bad memory hook with the metal reinforcement inside. I still don’t like the brownish color, and the L plug shape, but these are not functional critics, just aesthetic ones. CCA earphones have a similar cable, but a little bit better in my opinion. The shape of the IEMs is finally smart, because it hints at the shape of a custom earphone. Differently from ES4, this model is well built and good looking. The metal faceplate is really a nice touch, and I’m glad KZ took this way in various models (for example, the new ZS10 Pro). The new sister-brand CCA is doing the same. The fit is surprisingly good (only the ZS7 were good for me that way, but ES4 were uncomfortable and ZS3 were bad too for me), but not so stable. Better than CCA C10, which are a touch too big for my ears.

I got these together with the ZS7. With no great expectations, because I didn’t like the previous KZ monitors. KZ7 (here my review) were honestly surprisingly good, not only for the build quality and the nicer presentation, but also for the sound provided. I think they need a refinement on the low end, but they are surely enjoyable: ZS8 will be great if they manage to mitigate the mid-bass. These ZSN are good, too. But differently from the ZS7, they are less bass-oriented and more on a balanced side. Honestly, I feel they are the best tuned KZ I’ve tried.

Bass is punchy, pretty quick, but not overwhelming. It extends well in width, not so well in depth, but mid-bass is controlled and that’s the good point: mids are not covered.

Mids are a bit recessed, and it’s not surprising because these are consumer-oriented earphones, which have to be fun, even in their balanced character. Luckily, they don’t feel buried or lacking air, because the tuning is fine. I like vocals, which feel natural, and instrument separation is better than average. We are talking about entry-level earphones, so I obviously don’t expect miracles. But honestly these feel like one of the better choices on the price range. They just feel overload when the mix is really full. For a 20€ dual driver, it’s fine.

Treble is nice. I’m sensitive to sibilance and I admit there is some, but it’s not so disturbing. I hear no strange picks or notches; instead, a smooth yet precise reproduction of the high frequencies. Higher vocals are enjoyable too.

The soundstage follows the bass impressions: the width is okay, the depth could be better. Imaging is honest, precise but it’s like having some “steps” instead of a smooth reproduction around the space.

What I have to underline is the background noise, which is really exaggerated. It goes away by using an amp, but I believe that 20€ earphones are meant to be easily driven by smartphones. I think they presented the ZSN Pro because they needed that kind of upgrade, or refinement. Maybe if I’ll get them too, I would compare the two and verify this thing.



TRN IM1: really poor quality control on that model, and a strange tuning, make difficult for me to appreciate that model over anything else. I appreciate the effort of a custom-like cheap earphone, but driver flex, lack of air passing through, are serious defects. ZSN are cheaper (because of the materials, I believe) but sound way more mature. I put this more as an advice than as a real comparison. 

TRN V30: another TRN, another QC problem for me (nozzle filter gone). V30 look like KZ ES4, which I didn’t like for build quality, neither for sound. At least, I can appreciate the V30 for their sound. The soundstage is wider and deeper than the ZSN, and the background noise is way inferior. The tuning is comparable, while I prefer the materials and the build quality of the ZSN for sure.

RevoNext QT5: this is a difficult comparison. I love the QT5, because they are so complete for the price. Honestly, they have the same accessories and a very similar price, so I have to judge the build quality and the sound. Both are well built, but I don’t like the 2pin of the QT5 because they are too deep for most aftermarket cables (5mm vs average 3mm), and I don’t like the ZSN ones too, because they protrude too much. Sound wise, the tuning is more relaxed on the ZSN, while more on a reference side on the QT5. I generally prefer the QT5 tuning, but their sibilance is too much for my taste. They don’t have that background noise, though. If I had to choose, I may pick the QT5, also because of their steampunk look. If you ask, I’m a music lover and a design lover, too. Sound matters, and so does the look. I don’t write just for audiophiles, but for everyone looking for an overall good choice. Earphones are not just tools – some of them are, and this is not the case – but also aesthetic items, for me. 

CCA C10: a bit more expensive, these are a slight upgrade of the ZSN, but you have to appreciate more mid-bass to prefer them over the KZ. Honestly, I’m not that person: ZSN have a balance that I’d rather than the warmness of the C10, which are also bigger and the fit is not that comfortable for me; they tend to fall easily. What I prefer on the C10 is the absence of hiss, which is for me the only real disadvantage of the ZSN for their price range.



ZSN are one of the better choices on the market for 20€. Honestly, my previous experience with KZ, even in the same price range, hasn’t been that good. These are the first expression of their new design, and I hope they’ll keep this way. I’m just disappointed on the background noise, but the tuning is becoming more and more mature with the new models, and I believe the ZSN Pro really can be an improvement on this area. Before suggesting to buy these, I’d wait for my impressions of the Pro version, which have a very similar price, if I manage to get a pair.

Thanks to Easy Earphones (YinYoo) for providing this free unit to review.

So, here I am with my first KZ review in English. My previous experience with this brand wasn’t that happy (ZS3 and ES4, which I didn’t really appreciate). The first was too bassy, the second was too big and the sound – even if more balanced – wasn’t my cup of tea. Now I have the ZSN and the ZS7, and I can appreciate the progress of Knowledge Zenith. I wouldn’t expect this quality from a brand which didn’t surprise me in the past, at all.



Unboxing and first impressions

Like most of the people who want to start their IEM journey, KZ was one of the first brands which came to my ears. I was interested in trying the ZS6, but I changed my mind for the RevoNext QT2, a similar pair that I believed was superior. Since then, I hadn’t the opportunity to try the ZS6 nor to compare them, obviously, to the QT2; but I’m here now with the new model, the ZS7. The ZS7 share the same design as the ZS6, but the internals are the one you can find in the ZS10. So, even if this can make you confused, we are talking about a hybrid earphone, with 1 dynamic driver and 4 balanced armatures per ear. This is a similar configuration as the BGVP DMG, NiceHCK M6 (which I both reviewed here, in Italian) and the YinYoo D2B4 (yes, the “D2” name is a little tricky, but it may be actually a double diaphragm single dynamic driver). The fact is: the price of these multi-balanced hybrid earphones is actually really low. For 50$ on Amazon and even less on AliExpress, you can have a really solid model. Starting from the box, which is an elegant black cardboard with a book-like opening. Inside you find the buds, in their amazing electric blue, and underneath the foam you find the manuals, the eartips (unfortunately, the classic KZ ones) and the cable – which is so bad that I didn’t even open it, because I know it and I hate it. Luckily, YinYoo sent over a cable by themselves, which is perfect for this situation (if you want, you can find my review of it in Italian here). I have a color disease, but for me this coppery/pinkish color of the cable is a great match with the blue buds. The metal shell is really solid and very well assembled – I saw some macro photos before having my pair, and they looked kind of summarily assembled, but mine are actually well done. The back of the buds is black, but still metal; even the nozzle is made of aluminum. Because I put a cable which isn’t the stock one, I’ve also used some different eartips: I took the ones of the BGVP DM3, which I don’t use because they fall off my ears too easily. They are white too, which I prefer to the classic gray tips. The fit is strangely good, and not fatiguing. I can’t stand the QT2 which are similar, but these are better shaped, maybe.

Considering my previous experience with KZ, I thought I would have found a disappointing sound. I didn’t. These are my favorite KZ among the ones I’ve tried, and also among all the earphones I have. I’m a design lover, a music lover, I pay attention to various things. You can propose me the best sounding earbuds in the world, but if they are made of plastic, the fit is bad and they look ugly, I can’t appreciate them. Earphones are tools, but they are also jewelry nowadays. I can talk about them through the eyes (and ears) of mine as a musician or as an entire person with a lot of interest. KZ ZS7 are good. Good-looking, at first. Good-sounding, at last. I don’t usually like this sound signature: everything is in its right place, until you hear an exaggerated enhancement in the mid-bass area. But this is actually good. Once you understand that you can’t monitor your recordings with them and you have to pair them with particular genres, the way is clear. They are fun, exactly the same way as they look. You can chill with them, you can relax with them. The sound doesn’t reflect the angular shape, though. It’s not sharp, not harsh, not sibilant. This may sound like heaven, for someone like me. It’s not heaven, but it’s absolutely an enjoyable place.

Bass: not the best here. Sub-bass is lacking, mid-bass is emphasized. If I had to find the issue with these IEMs (apart from the cable), it would be this one. Once you get used to this, though, you appreciate the bump. Bassheads will be fairly pleased with this pair. I would rather have more speed and less oomph, because the mids may suffer from that. But I’m okay with the extension and I can survive with the emphasis.

Mids are great. Even with the “invasion” that sometimes comes from the bass. I like voices, I like the space between the instruments, their layering. Maybe you can expect more detail by a set of four BA, but I don’t feel I miss any main focuses in my music. Vocals aren’t sibilant. This is something I’ve waited for since a long time, for a KZ earphone. I like everything of the sound, honestly, apart from that bass. Treble is smooth, not extreme but luckily not harsh. I enjoy it, and I’m not an easy person to satisfy when it comes to high frequencies. Even the highest voices are well controlled, and don’t miss any air or space. The soundstage is average. Not the widest, not the deepest. But the imaging is very precise, so you can enjoy your perceived little room and be happy. The intimacy is achieved. I wouldn’t call this stage “small” in a negative way. It actually opens up when the recordings are well done. But I’d call it intimate, because it’s very in-your-head sometimes, without being intrusive. And the mid-bass presence actually gives a very warm color to the signature which is really emotional. I have to say, I’ve wanted to like KZ since a long time, but it’s been hard, until now. ZS7 are a game changer for this brand.




This is a very interesting moment: the price range is challenging and I have a lot of competitors. I’ll write some, but if you need others, write me on the comments or contact me anywhere.

YinYoo V2: they are among my favorites IEMs. I still prefer them over the ZS7, because they come with better accessories (carrying case, better cable, better tips). Even the sound signature is suitable for more genres, because its bass is more controlled. I’d rather the ZS7 design. I say it now: it’s neary a 1:1 clone of the Campfire Audio Andromeda (and Polaris). I don’t appreciate brands which clone stuff, of every genre. They are even more similar to them than the RevoNext QT2. That said, I love the Andromeda design, so I cannot dislike the ZS7 that way. It’s not ethical, though. If I had to choose, I’d take the V2.

ADVANCED Model 3: they are similarly tuned. But the mid-bass bump is more exaggerated on the Model 3 (strange to say!). I love the Model 3 because of their design, their accessories, their shape and their fit. That said, the ZS7 are better built and to my ears they are more finely equalized. OT, I’m curious to try the new models of ADVANCED, because they have the perfect shape for me, and a more similar driver configuration to these ZS7 (even though I continue to like the dynamic vibes). I’d choose the ZS7 between the twos (I’m talking about the wired version of the Model 3 in this comparison).

RevoNext QT2: I like them, I don’t like them as much as the ZS7. They are very differently tuned, QT2 are on a reference side and they are bright, while the ZS7 are dark and fun. Same accessories here, so I can give you my preference: ZS7, because QT2 are too sibilant and I can’t stand that. And ZS7 are more comfortable.



This time they did it: Knowledge Zenith is improving. I (more than) like the ZS7, and they are on my top list now. If they put a better cable instead of that crappy memory wire one, the improvement will be complete. And they could compete with the bigs. They just need a little bit of refinement in the tuning. But the ZS7 are solid, and I’m happy to recommend them.

Thanks to Simgot for the review sample.

It’s been awhile since I’ve tried my first Simgot set of earphones, the Meeture MT3 (here my Head-fi review). I kind of liked that monitors, with a particular vocal-centered tuning which makes them perfect for singers’ live stages. They were comfortable too, so with the right eartips they were a really capable IEM. However, the tuning was a little bit unorthodox, that’s not a bad thing, but it’s something you need to get used to. These EM1, instead, are very well-tuned and easier to appreciate. Let’s see why.

Unboxing and first impressions

As you can see, the difference between the boxes is noticeable: I liked the rational small white box of the MT3, but this bigger black one of EM1 is classy and more elegant. There’s a High-Res certification and some black-on-black pictures and specifications on the various faces of the box: I like this style, but I have to say it’s a bit difficult to read what’s written.


As always, we find a soft carrying pouch with a good number of silicon eartips: 3 wide bore ones, 3 small bore ones. They really change the sound a lot, so be careful to try them all before judging the set. Like on the MT3, I prefer using the wide bore tips, because the sound is more balanced and less “boomy” than the sound provided with the others. It’s nice to see a description of how the sound changes depending on the eartips used, not just because they help with your choice, but because it’s very accurate. Unfortunately, there aren’t any foam tips, but the nozzle is pretty standard: I’ve tried both the Tin HiFi foams and the NiceHCK foams and they all fit very stably. The cable is really good: the same as MT3, a really well-made braided one. It’s oxygen free, 4 core, 6N of purity; a standard single-ended 3.5mm gold-plated jack and 2-pin 0.78mm connectors for the buds. There are pre-curved hooks and they are very comfortable, and there’s a chin slider too. The IEMs themselves come in a beautiful choice of colors: even though you can buy an all-black model, mine has the right earbud in red and the left one in blue. This makes it way easier to recognize which way to wear them. And the eartips are red/blue too, so it’s a beautiful touch. The buds are made of metal and plastic and they are actually the best plastic earphones I’ve ever tried regarding the build quality. It’s a translucent colored plastic, so you can still see the internals: you can notice the dynamic driver, which is the only one used in this set. The nozzle and parts of the faceplate are made of metal. There are some elegant writings. Overall, design wise this set is one of my favorites.

When you try a lot of earphones, it’s difficult to get surprised: some sets have a good tuning, but they lack of detail, or vice versa. Some others have a really good bass, but they fall on mids and highs; it’s difficult to find a 360° convincing IEM, because brands obviously have to aim at a particular feature, especially on the budget area. Well, for my taste, this is one of the most convincing earphones under 100$. I may say this now is my favorite IEM.

Usually, when I start trying an earphone, I immediately understand a general tuning of it. Whether it’s a flat one or a “V” one, a balanced or a flat. In this case I needed more time to understand. First, I thought this was a warm set. Because bass sounded very punchy, quick, perfectly controlled with a dark background. Then I thought this was a bright set, because I started hearing some sparkles and a slight sibilance. So, I started thinking about a classic V-shaped signature, but I heard no evident fall on mids. Well, this became a really interesting set. I’d say, after listening to them for some time, that I’d remain with the initial impression of a dark background: the overall bass area is solid and gives warmness to the scene. That being said, the treble is surprisingly capable with a great detail and some sparkles, which however don’t bother me, as a really treble-sensitive person. I still hear some sibilance, which it’s not a characteristic of this set, but it’s an evidence of some not-so-well recorded songs: exactly like on Tin HiFi T3. Mids are great: I think they are slightly recessed, because the final impression I have is having a smooth U-shaped signature, which isn’t lacking of body nor lacking of air, though. I hear a very good separation between instruments and a pretty airy sound, with good detail and resolution. Soundstage is average: it doesn’t feel very wide, but neither inside your head. It’s something close to holographic which however doesn’t give the impression of a “virtualization”. And imaging, through this perceived small room, is actually pretty accurate.

To summarize: bass is very well-extended on the sub-bass area, present but controlled, punchy and pleasant. Mids are clear, with airy vocals and a good layering between instruments. Treble is solid and absolutely not rolled off, with a precise and analytical feel. Soundstage is average in width and depth, but imaging is really believable.

Simgot Meeture MT3: while they share the same accessories, materials and build quality, sound wise they are pretty different. Depending on the tips, MT3 can sound really V-shaped (small bore) or mid-centric (wide bore). EM1 are more balanced and provide an overall signature that’s more classic and pleasant. I could recommend the MT3 to singers for their live stages; but I can really recommend the EM1 to anyone, whether for music listening or music production or exibitions. These are really solid universal IEMs with no compromises. You can find the MT3 here: https://amzn.to/2GTFyxN


Tin HiFi T3: when I said that most of the times brands need to make decisions, I meant that earphones like Tin T3 are amazing under certain ways, but average on some others. T3 are fantastic if you need detail, they have a really good bass yet remaining bright and they absolutely don’t fall on mids. And they have the best cable on a budget, too. But they are less comfortable to wear and more fatiguing to listen to. I feel that EM1 are more cohesive in their frequency distribution – but it’s easily because of their only dynamic driver, while T3 are a hybrid solution. I personally choose EM1: they may be meant for a more casual listening, because of their less-analytical signature, but they are more pleasant to my ears and they don’t really make compromises. T3 do maybe “too much”: they need to smooth their treble a little bit. Still a great set, though, with a stunning design. In absolute terms, they may be superior. For my personal taste, which requires a more controlled treble, EM1 are a better choice. You can find the T3 here: https://amzn.to/2XcI206


BGVP DMG: very different in terms of drivers (it’s a 5 or 6 drivers hybrid), and also in terms of sound. DMG are more sibilant, and provide a less smooth sound through the frequency range. They are warm too, but they aren’t as punchy neither as controlled as the EM1. I like EM1 treble more, too. Mids are similar and soundstage depth too. Fit wise, they are both great and not fatiguing. I like them both, honestly; DMG may be a little bit more detailed thanks to their multi-balanced configuration, but the overall experience of EM1 is closer to my taste.

EM1 are an easy recommendation for me. I wasn’t so sure about MT3, but this set here is close to perfect for my taste. If you search for the most balanced choice in every way, consider this set. If you are more into crazy detail or very wide soundstage, there are better earphones, which aren’t that solid though, at least for what I think. This actually is one of my favorite IEM ever – and it proofs what you can do with a single dynamic driver, even on a budget. Highly recommended, in the end.
