Intro: The KBEAR KB06 is a recent release by the relatively new company KBEAR. The KB06 is a 2BA 1DD hybrid which is not common in the under $30 range where you mostly find 1BA 1DD. In the under $30 range, ChiFi fans usually recommend the KZ ZSN or ZSN Pro or Sony MH755 as I have done here in the past. The KB06 is another alternative offering a more natural sound, better soundstage, and plenty of bass. I think those characteristics will appeal to some users looking for recommendations in the under $30 category.

Fit and Finish: It is quite small and very comfortable. The shell is teardrop in shape, metal back plate and resin transparent shell. There is a vent on the backplate, but I did not try covering it up to see how it affected overall sound. The cable is straight out of the KZ warehouse, the standard braided copper brown cable.

Sound: When I mention the KB06 as an alternative to the KZ ZSN Pro, it is very dependent on the music preferences and tolerance for bass. The KZ ZSN Pro is more consistent across genres of music whereas the KB06 can be more of a wildcard in how it responds to the synergy of bass, vocals, and instruments.

I am a fan of heavy bass but it also needs to sound pleasing to the ears. There is no doubt the KB06 can supply plenty of bass, but I would prefer it to be a bit more restrained and defined. Other than the initial wow factor of the bass on an initial listen, I think it would have been better to match the quantity with the quality. In this case, the KB06 responds well to bringing the bass down a notch with an EQ. My favorite bass notes were mostly pure mid bass, big punches of bass or plucks on an upright. The natural sound comes thru more than a big EDM sub bass movement which doesn’t quite have a matching texture and richness versus the quantity of bass.

The mids are where it is at with the KB06. Female voices, guitars, most instruments sound surprisingly good. Voices are also brought very forward which is again another tuning choice that will either attract or turn off some folks. When you combine a clear, strong vocal with a wide soundstage, it can sound very, very good. That was one issue with the ZSN Pro, not nearly as wide and you will miss some of the airy-ness and reverberations of the vocals. One issue with the mids was the clashing of the forward vocals and other instruments such as guitars. In Lady Gaga’s Joanne, she sings and plays the guitar, but if you follow the guitar, it will get lost behind her vocals. Other singers and guitars do not show the issue but something to be aware of if you are a critical listener.

The treble tries to avoid peaks and brightness. It seems to roll off early and some details will be lost in the upper ranges. I think this was a better decision and let the mids shine where most popular music lives. For this reason, rock, pop, country, and other popular genres work well. I do listen to quite a bit of EDM and this is not my favorite for that genre on the bass side as well as the treble where you will lose texture on some of those computer-generated noises. I think the extra BA does present more natural instruments but not nearly as helpful on more computer-generated sounds.

Conclusion: I have been asked here and other platforms for recommendations in the $20-$30 range and I think the KB06 is a valid choice for some people. Obviously my next question would be what are your music preferences and bass tolerance, but I think the strong vocals is attractive to many people and useful in higher noise listening environments.

Pros: Rather clear sounding, Good imaging, Great construction, Cheap price
Cons: Sloppy bass, dryish-brightish timbre, lack of highs sparkle, slightly agressive in upper mids lower highs
KB Ear KB06 review :

SOUND: 7/10
DESIGN: 8.5/10
VALUE: 7.5/10

KB Ear is a rather new ‘’chi-fi’’ comer, and receive mitiged praise for their audacious iem wich use a single balanced armature. This was due to quality check issue as well as using different drivers models for the same iem, leading to paradoxal impression including mine that wasn’t positive at all.

Now, because of F1 intense covering from multiple audio enthusiast as well as reviewers, their third model pass under the radar. This is strange due to the fact it use an hybrid dynamic + 2 balanced armature implementation and they cost near half the price of F1.

One thing sure, they sound better than both pricier F1 and even I4. This is why I feel obligated to review the KB06, because they are the best KB ear earphones yet even if they choose a very commun ‘’chi-fi’’ tuning wich consist of V shape plus upper mids emphasis to create a balanced but slightly brigth musicality.

Now, let’s see if at around 20$, they can be considered a good bet for budget audiophile.

The KB Ear KB06 can be found for around 20-30$ in multiple ALI EXPRESS stores.

UNBOXING is expeditive and remind me of KZ earphones. You open a little box and got the minimal wich is earphones, a braided 2pin cable of similar quality than the KZ one and 4 pairs of silicone eartips. At this price, I do not exactly ask more than this.

P1040389.JPG P1040388.JPG P1040390.JPG P1040391.JPG

CONSTRUCTION is quite nice and i’m impress by the very small half metal half plastic housing, back black metal plate have a nice finish to it and well implemented open back vent with a mesh. Cable is okay, using new improved KZ cable, but I will not use it because I don’t like earhook.

is well thinked and I hope this housing will be use for other iem as well, its very small and the angled shape with long nozzle make it very comfortable and easy to fit any type of ears.

ISOLATION is average and as its an open back iem, their significant sound leakage that can be problematic in silent environment or working place.

DRIVEABILITY is quite easy with its 111db sensitivity and 24ohm impendance, but you need minimal amping capabilities nonetheless to expand soundstage and dynamic. Any DAP would do, but for a phone I suggest at least a USB-C dac-amp cable.



Overall sound impressions was rather positive due to my very low expectation after hearing the F1. This time I feel KB06 was well tuned, delivering clear bassy sound with bright mids and vivid upper treble. Soundstage wasn’t the most impressive in term of widness but deepnest was good as well as overall spacial placement. But as always with cheap balanced armature, sometime about timbre annoy me, now it was more about thinnest and dryness of it, as well, lower bass go out of control and can became problematic.

SOUNDSTAGE is okay for its price range, it do not feel stock in your heard, but you have intimate widness without alot of tallnest and quite alot of deepnest….make you feel in a tunnel in some way.

IMAGING is more about upper mids and treble here, and if big bass occur you will struggle to find proper instrument placement in mid range. It’s pretty frontal and fowards, nothing to applause here.

BASS have good extension but pump up the sub bass quite alot, still the mid bass kick is fowarded too, even agressively, wich make it for an exciting listen but not a very accurate one. The lower end tend to sound sloppy and uncontroled sometime wich lead to mid range veil or distraction. For example, cello will sound very bodied but violin will struggle to find its place at its side. Its not the fastest bass as well, wich affect overall transient response.

MID RANGE is slightly pushed fowards, but the mix of thick bass and thin mids make it a strange one, still, level of clarity is quite high until the upper mids drop. The vocal are a little recessed when bass occur but we have good details in texture, timbre is transparent and slightly grainy. We do have hint of sibilance as well. Separation in this range is okay for its price. Mids aren’t very bodied and exciting to listen to and lack attack-decay and weight.

TREBLE isn’t particularly emphased, as if KB want to give all they got into the mid range, wich is not so balanced to my ears. So, your percussion will sound quite far away in the background, at least their no foward splashiness but neither their enjoyable sparkle too. We are in a dry territory, with some lower treble peak to extrack as much lower range details as we can. It work to some extend and give extra air to soundstage, but it affect richness of timbre as well as….lack of micro details.

SUB BASS : 6.5/10
MID BASS : 7.5/10
TREBLE : 7/10
TIMBRE : 7/10
IMAGING : 8/10


VS **** **** (20$) :


What hit you first is how wider, taller and more around your head feel bigger soundstage of ****, as well, instrument separation is more articulate and spacious, making the KB06 feel very congested in comparaison. BASS of **** have more body but less mid bass punch, still, it sound more natural and fuller than dryer and sloppier KB06 bass. We can say **** is more U toward W shape while the KB06 is V plus upper mids push, wich lean to a brighter MID RANGE that sound less alive and coherent than ****, wich present vocal in a wider and more transparent with a more natural timbre, instrument separation in this region is well layered with **** and more constraint and compressed with KB06. TREBLE is more extended with **** and offer more details as well as highs sparkle and decay, the KB06 have grainier and harsher highs that sound more agressive while **** is gently trebly.


Now, its time to the SPACESHIP to offer notably smaller soundstage and for a spacial ship, it do not have a big space to travel into either, while KB06 is above average for its little price and offer more space between instrument, or more specifically between low, mids and highs frequencies range. BASS is as well more authoritative and pumped up with the KB06, making the Spaceship sound more neutral and flatter and lack in lower bass extension. MID RANGE have as much presence but due to more spacious separation, vocal and instrument do not mix as much with KB06 wich keep them cleaner and offer greater definition. TREBLE is more extended with emphasis in upper highs for the Spaceship, wich give it extra sparkle KB06 lack, classical guitar or harp have more brilliance, but the attack is less energic than KB06 wich make overall listen flatter and less exciting than KB06.



Kbear work hard to be recognize among audiophile and even became a sponsor here on Headfi, but to gain more credibility among our community, I think they will have to work harder on tuning and acoustic implementation of their drivers. Here, when I praise the small housing, it isn’t because of its acoustic implementation that put the dynamic driver too near the back of the 2 balanced armature that for their part take too much place into the nozzle...even if i’m not a sound engineer, what I here can be connected to this ackward configuration.

Still, the result isn’t that bad as the level of clarity of mid range is impressive for a slightly V shape iem even if the lower bass rumble can affect it drastically. As well, with the right ear tips you can expand soundstage and gain extra articulation in imaging.

All in all, KB06 remind me of chi-fi old days where tuning work came second to mass production concept and do not stand appart from the average contenders. Its neither good or bad, and sure offer nice price value if you are new into budget earphones. The construction is excellent, the sound is okay, the price is competitive at 20$ but not at 30$.

Reactions: B9Scrambler
Pros: generally good sound performance
mids are not too much withdrawn despite V-signature
good details and resolution
fun tuning with pushing mids
Cons: sometimes too much middle and upper bass, which then pushes too much into the mids
some peaks that become fatiguing in the long run
KBEAR hasn't been on the market too long yet and has proven its luck with its previous models, sometimes more, sometimes less. But so far there has not been a complete breakdown. The KB06 is a hybrid, consisting of 2 BA drivers and a dynamic one. Similar configurations can be found in the TRN V30, KZ ED16, HIFI WALKER A7, or REVONEXT RX8s. The KB06, I see behind the RX8s followed by the V30, which makes the KB06 the best KBEAR in-ear so far at a fair price.

The seat and fit of the KB06 are fantastic. In addition there is the compact design, which shouldn't cause any problems even for small ears. The feel is exceptionally good in the budget range due to the metal plate and the round design, which makes the KB06 a perfect companion in everyday life. However, the cable is a bit fiddly and resembles the one that Knowledge Zenith also adds to its in-ears. You have the choice to order the cable with or without microphone.
The colours are a silver metal plate on a cyan-coloured synthetic resin housing, or transparent with a black plate.

The other accessories are very spartan, typical for KBEAR. Cables and three sizes of silicone tips. That's it!

The isolation is excellent for me with the biggest tips. As with so many Budget-In-Ears, the driver flex is a small drop of bitterness, but it doesn't influence the sound. Admittedly, the Campfire Solaris isn't exempt from this either.

The KBEAR is not only the best of the company, but also a good one compared to the competition.

The bass concentrates more on the mid and upper bass, but is also not sub bass shy.
This makes the KB06 a rather warm representative, which is well absorbed by the BA drivers. Nevertheless, it can sometimes be too much in the upper range, so that the bass sometimes lacks clarity and control in connection with the not quite so present sub-bass. Basically, however, it is very punchy and powerful. But here I like the performance of the TRI i4 more.

Compared to the recently reviewed TRI i4 (which is also a KBEAR brand), the mids are more "In Your Face" which I like more than when I always have the feeling that I have to look for the mids in the mix, which makes some genres rather exhausting to hear. The KB06 almost manages the balancing act between forward going mids, but without too much sibilants or unpleasant peaks. The latter is unfortunately already present in some songs, especially when high female voices are involved. This leads to fatigue in the long run and does not always guarantee a long listening pleasure, depending on how sensitive you are in the frequency range. The separation and the stage, on the other hand, isn't quite as successful as with the TRI i4, but this is also due to the more present mid-range. If the mids come into play more, this is usually at the expense of a more intimate stage, which is not necessarily bad, but a matter of taste.

I wouldn't call the highs boring, because they can reveal enough details and give the required airiness to the overall sound. However, some frequencies are sometimes more emphasized than others, which makes them more prominent than they actually have to be and vice versa. This doesn't make them as transparent as one would wish, yet the heard remains interesting at all times. Similar to the mids, peaks appear here and there, which are then also amplified and thus do not always provide a relaxed listening experience.

If I write that the KB06 are the best of the company, it doesn't automatically mean that one should expect miracles here, because KBEAR was somewhat inconsistent in its previous models. I see the KB06 on a level with the TRI i4, where the KB06 puts the mids better, but doesn't have the precise bass. I find the TRI i4's highs more transparent and homogeneous, but the KB06 has a bit more expansion. Occasional peaks and sibilants both have to offer, which doesn't always make them the most relaxed companions. Of course, the price difference between the two models should not be forgotten. Nevertheless a good in-ear for a good price!
