New Head-Fier
Only valuable thing in those earbuds is shell
Pros: -comparable to previous version is much lighter (aluminum shell?)
-quite nice bass, not that it became better than first model
-convenient fit
Cons: -shallow medium and high frequencies
-bad assembly quality
-cheap dynamic driver
-hugely overpriced
Everything being said is concerning gold 150 Ohm version of st10s. I happened to obtain cheaply gold version of Smabat st10s. at first glance i was confused because gold color was almost transparent, and thought that seller messed up and sent me silver version, but after checking resistance with multi-meter it showed honest 150 Ohm.
First impression that they are almost weightless, in my memory first version felt was quite hefty in ear, but in my opinion less weight - better. Another thing - earbuds had unpleasant sound of wobbling inside, maybe long loose wire?
Secondly, they just have no scene, trying to find at least something interesting in high and mids but they were just too descended. it felt like earbud are a bit deaf. Even low frequency not saving the day. I remember how deep were lows in previous version of st10, here they are just good, nothing more.
Being quite disappointed by sound i decided to see what kind of driver smabat decided to insert in those earbud, and well.. it is saddening. Inside is cheap dual material membrane driver (plastics/metal), wires are already frayed near the driver (nice quality from manufacture) and in my opinion for this build quality and driver choice eabuds are just overpriced, totally a letdown. But it might be a good shell for some decent driver if you had them dirt cheap and like diy ¯\_(ツ)_/¯

update, tried to use this shell with one of my favourite 15.4mm driver and it doesn't worked out, unfortunately its just some fail of earbud for such price tag.

You might not be getting enough power into them, they ARE 150 ohms, and the E10 only supplies 150 mW at 32, the BTR5 is only 50 into 32 ohms. LG phones can drive up to 600 ohm headphones, maybe look for a friend who has a quad dac phone?

Smabat ST10S - an earbud with a silver lining
Pros: Lots of detail, good low end, very clean signature, polite treble
Cons: lacks a little weight and warmth to the mids.
smabat-st10s-pair2-scaled.jpg


Disclaimer: NiceHCk sent the ST10s for review because I had reviewed the ST10 and M2 Smabat models previously. I was interested to hear the new Smabat offerings and how they would compare to the original. I hope to add the gold model as well soon. If you have an interest in purchasing the Smabat ST10s, check with NiceHCk via their aliexpress store.

Unboxing / Packaging:
The ST10s ships in a flat black slip-cover box with the Smabat name on the front in Gloss black. This is a bit more subdued than the original with its gold labeling. The rear has a label with model number and basic specs. Once the slip is removed, lifting the cover reveals the buds displayed in a card, stock covered foam. The reverse side has the foams tucked neatly in holes cut in the foam while the cable rests in a small box in a notched cutout in the foam. beneath that, a lower layer has the warranty card, manual, and carry bag. Kit is fairly standard with foams, and rubber earpeice covers, cable, and case. Foams include both solid and donut models so pretty much all the earpiece options are covered. I generally choose to listen without any cover on the tips as it has a tendency to impact the sound. I do like the rubber covers though for exercise use as they make the buds much easier to seat and retain during periods of movement.




Build/Fit:
Like previous models, the St10s uses a 15.4mm driver so the earpieces are necessarily large to house the driver, but taper quickly behind that so fit is still fairly easy for most. Those with small ears may wish to audition these before purchase to avoid any issues size may cause. About ½ way up the taper is a small silver band with small vents immediately to the outer portion of the cone. These are spaced to avoid blocking them with the earpieces worn tip up and some adjustment may be needed to prevent blocking them if worn tip down as I found. Most of what changes by blocking the vents is the lower mid-range so if you suddenly have clouded mids, check your vents.
The outer housing shares the transmission line style venting of the original ST10 but is supposedly an improved version for even more bass depth. The housings have a silver outlined black face gray/green outer shell with the driver housing being primarily black plastic. Fit and polish are good with no gaps around the mmcx connector and all edges slightly beveled for comfortable wear. Left and right are labeled on the spine of the housing leading to the mmcx connectors. MMCX connectors are good and tight (unlike my assessment of the original).




Internals:
The Driver used in the st10s is a 15.4 mm dynamic driver with a titanium coated peek diaphragm. Nominal impedance is listed at 40Ω with a sensitivity of 115dB/mW. The original had slightly higher impedance and slightly lower sensitivity and really required a solid amp to do its best work. I am happy to report that this new ST10S silver is usable from a cell phone or tablet and while using a higher powered source will give it a bit more low end punch at times, it doesn’t feel anywhere near as under-powered as the original did when run from the same phone. The Transmission line cabinet has long since been a staple of speaker design but hasn’t been used much for headphones or earphones as it takes up a good bit of space compared to a standard vented design. Smabat is now on its 3rd generation of this housing and keeps tweaking it with each new revision. It is interesting as a pure engineering experiment to look at the generations of product in this respect.




Cable:
The cable provided with the original ST10 was also a bit outside the norm as it isn’t often we see an earbud with a cable designed for tip-up only wear. It seems maybe enough people found that odd to result in the changes we see in the ST10S version. Gone is the cloth coating with the cable now being housed in a clear casing showing off the silver plated copper cable. At the lower end, the cable uses a 3.5mm straight jack with a polished metal housing and a short strain relief. The splitter matches the jack in style and has a clear plastic chin slider above it which is well fitted and stays put when set. The top end still use mmcx connectors, this time in clear/metal housings without earhooks. The metal is marked clearly with L/R for indexing purposes. Interestingly I mentioned preferring the ALO tinsel cable to the original provided with the ST10 and the ST10s now ships with a cable that is very similar in style and construction to the Tinsel, so either they took my advice or it was pure coincidence. Either way, I like this new cable considerably better than the 1st generation.



Tips:
The ST10s provides, foams, donut foams, and a vented rubber tips. I found that the rubber tips did help with keeping the ST10s from migrating during activity but found it to be the most signature changing of the three and decided for sake of this review I would conduct all sound notes with none of the tips installed. Understand that your impressions will vary if you install tips and especially the rubber tips.



Sound:

Remember that looking at the FR chart on an earbud is always misleading as buds are not meant to be sealed and almost every test rig is going to seal the face of the driver to a greater degree than actual wear.

Bass:
I was surprised by the amount of sub-bass on the original ST-10 so this time it came as less of a surprise. Sub-bass is still very good with more presence than most earbuds. It won’t satisfy bassheads, but gives the 10s a near neutral tuning without feeling like the low end is rolled off or forgotten. Mid-bass is roughly level with the sub-bass and has good clarity and detail. A lot of the clarity is due to the speed of the driver which is faster than most on both attack and decay but stops short of being too quick and impacting note weight. Mid bass bleed is very minimal as a result of the tuning and driver speed. I had noted a bit of artificial sound to the original ST-10 and am happy to report the 10s is a bit more natural in tone.

Mids:
As mentioned, mid-bass bleed doesn’t obstruct the lower mids which have the same clarity and detail as the lows but lean slightly to the cooler/thinner side. It is clear in the mids that Smabat prioritized clarity over warmth. Having said that, guitar growl is still believable if not quite as aggressive as could be. I found male vocals to be just slightly behind female and a touch less lively but still well defined. Female vocals cut through the mix and do border on stridency at times but do a good job of walking the line and not getting sibilant. Strings lack a bit of weight but again have good clarity.

Treble:
Lower treble has good energy and follows the upper mids before falling back a bit as we move up. The treble is polite and well detailed with some air but sparkle feels a bit limited. Extension is good with final roll-off being above my hearing, but it does drop back in volume above about 8kHz which may be the reason sparkle feels a little reserved. Speed shows in the treble as well with snare having a crisp-edged attack and cymbals having good sharpness as well without becoming clicky.

Soundstage / Imaging:
Soundstage is roughly the same size as the ST-10 with good depth and width and even some sense of height. The driver speed contributes above average instrument separation which makes seating the orchestra straight forward with no large gaps or misplacements. Imaging is good but due to the open nature of the buds the positions are sometimes a bit more general than exacting. Layering is quite good for a single driver with little tendency to thicken on complex tracks.

Comparisons:

Smabat ST-10
Shells are a wash as is the cable so sound is the distinguishing factor between the original and the S. The S is as bit more neutral and a bit faster while the original is a bit more weighty and a touch warmer if a bit less detailed. I found the bass slightly less emphasized and detail retrieval a bit better. If you like the ST-10 but wanted a bit more clarity, the 10s will be well received.

NiceHCK EBX
Build Quality – Buds themselves are roughly equal with the EBX kit being a bit higher quality than that of the 10s.
Sound – EBX is thicker and less detailed in the mid-bass and lower mids, giving it a warmer richer tone at the expense of detail. The 10s offers a bit more sub-bass and cleaner mid-bass and mids but lacks a touch of warmth in comparison. Vocals are a bit more lifelike on the 10s as a result of the tuning. The EBX needs less power to drive well so may be a choice for those limited to lower powered sources. I prefer the clarity of the 10s and the more natural voicing.

LYRA Classic
Build Quality – The Lyra would win hands down if not for the fixed cable. The buds are roughly equal but the kit is much improved on the Lyra.
Sound – I picked the Lyra over the original ST-10 for its more natural tonality and while the 10s makes moves in the right direction, it doesn’t quite get to the level of the Lyra. The 10s is better extended and has considerably more sub-bass so will appeal to those who want a similar tonality to the Lyra without sacrificing lows to get it. While the Lyra bettered the detail retrieval of the original ST-10, the 10s is now roughly on par with it. The Lyra remains easier to drive, but the 10s also closes the gap some here too.

Thoughts / Conclusion:
The original St-10 proved the transmission line style case was more than just a gimmick and could actually produce a good sounding earbud. The 10s proves that SMABAT continues to refine that design and improves on an already good listen. I found the 10s (silver) a bit cleaner and faster than the original with a slightly leaner tone and a bit less boosted female vocals while still retaining some emphasis to keep them ahead of the other instrumentation. The 10S retains the bass depth of the original and the top end extension, but cleans up the territory between the two. The one knock will likely be that they are slightly on the thin/cool side and some will miss the warmth of the original. The ST-10s certainly deserves an audition if you are looking for earbuds as the clarity is probably as good as it gets for the price. Its just a matter of whether the tuning works for you.

Introduction

Smabat continues to grow and based on the acclaimed ST-10, has created two new earbuds: ST-10s Silver and ST-10s Gold. One difference between them is their impedance: 40Ω for the Silver version, 150Ω for the Gold version. The other is based on the composition of the diaphragm. Compared to the ST-10 version, the particular maze-shaped structure is larger, the driver has been revised and the cable has been changed. For the Silver version, the new driver uses a similar configuration, whose diaphragm is 3 layers, but revised to version 2.0. Meanwhile, the Gold version, uses a particular diaphragm, which aims to generate a different sound, somewhat cooler.

On the sound level, the version to be revised, which is the Silver, is a kind of mix between the old ST-10 and the M1. It maintains the power of the lower zone of the first ST-10, but improves the refinement, adopting, also, the more detailed and vivid profile, of the M1.

Let's see, in depth, the improvements of this new version.

Packaging

This time, the Smabat ST-10s comes in a box with smaller dimensions than its previous version: 131x99x39mm. Its color is satin black. On the front face there are only inscribed, the letters "smabat", plus a yellow sticker, in the lower left corner, with the content of in icon, under the phrase "Coiling-Up Space Acoustic. Powered By Smabat". On the back side, another sticker, this time on the bottom, containing the specifications, the brand logo and its address.

After sliding the box, the capsules are shown, stuffed in a rigid foam mould, lined with black cardboard. After lifting the mould, a large round hole can be seen, behind which a brown leatherette cover with the brand name can be seen. On the back of the mould where the capsules come, the tips are embedded. As a summary, the complete content is:

  • Smabat ST-10S.
  • 1 pair of plastic tips.
  • 2 pairs of foam tips.
  • 1 cable.
  • Brown leatherette bag
  • Instructions.

The packaging is slightly different from the base model, the cover seems more useful, with a flexible band closure, more suitable. Although it is small and not rigid. The tips are still very scarce and insufficient. As an accessory, the silicone tips are repeated, of doubtful utility.

I think that in this aspect, the variations are minimal and the accessories are not up to the price and its claim of a premium product or flagship.

Smabat ST-10S 05_resize.jpgSmabat ST-10S 06_resize.jpg

Construction and Design

The external design has hardly changed from its predecessor, except that the maze-like structure is larger. It changes the color, now it's black and silver. The cable, also different, is made of silver-plated strands, covered by transparent plastic. It's similar to the M1 cable. It has no guides over the ear and its connections are MMCX, gold-plated.

Otherwise everything is very similar: The earbuds are formed by two capsules joined by a relatively thick central axis. In the rear capsule is the acoustic cavity. In the front capsule is the driver. Smabat uses a titanium diaphragm, three layers (PEEK, PU and PEEK), a patented acoustic cavity, made of aluminium, in the shape of a labyrinth. In addition, they use an advanced acoustic and ergonomic design. 9448A plates are used to seal the labyrinth. The outer plates are made of steel. The MMCX connections are gold plated. Under the labyrinth piece, there is a large bass port, covered with a grill. There are holes in the cones of the capsules.

As I say, the design hardly changes, although the colours are more flattering and elegant.

The cable has a slight rigidity, which I don't like, but the absence of guides, allows the use downwards or over the ear. Although, the sound is not the same, I prefer the classic use, over the ear.

Smabat ST-10S 07_resize.jpgSmabat ST-10S 08_resize.jpg

Adjustment and Ergonomics

The peculiar design, allows its use on ear and the absence of guides in the cable, offers the possibility of being placed with the cable down. However, it is true that the rigidity of the cable and the absence of guides makes the over-the-ear fit less durable. The ergonomics have not changed, but the cable is still inadequate for the design of the earbuds. Fortunately, it can be changed.

As a result, the best fit for the fullest, most complete sound is a bit complex and not very suitable for use on the move, as the slightest mismatch can ruin the production of the best sound.

Sound

Profile


As I've been saying, the Smabat ST-10S sails between its predecessor and the M1. In this way, their profile is a compendium between both models, since they balance, on one hand, the low part of the ST-10 and the mids of the M1, getting a more neutral and balanced sound, offering a good punch in the low zone, less forced and natural mids and soft, but aired highs.

Smabat ST-10S 11_resize.jpgSmabat ST-10S 12_resize.jpg

Bass

The improved enclosure of the S version is noticeable in several ways: the depth and width of the bass have been increased. The impact is more moderate than in the previous version, but the clarity and precision are also greater. The result is a bigger scene and a more spacious sound, which is noticeable from the first beats.

The texture of the lower zone is perceived as softer, sweeter, more pleasant, with a compact and rounded hit, of remarkable power and execution at the same time. The speed neutralizes its power and gives it notoriety, both at the level of resolution, as in the details and different planes. The set generates an area never swollen, which turns towards the naturalness and that full sensation, halfway between the sound produced with IEMS (for its execution and level) and some acoustic boxes (for its power of recreation, openness and realistic depth).

The sub-bass range is perceived, but it is in this area where the colour and texture is lost, and the naturalness of the rest of the lower area is affected, and its performance is somewhat more limited in quality.

Smabat ST-10S 13_resize.jpgSmabat ST-10S 14_resize.jpg

Mids

The clear vocation of model S is aimed at greater neutrality, something that is demonstrated in the central range. It is here that realism and naturalness are raised to their best. The mid-range feels quite liberated from the lower zone and clarity is perceived as increased, as well as space and separation. The comparative warmth is rather less, one could even say that the tonality of the mids is somewhat colder. In this sense, this fact is not harmful, since it helps to reduce, until disappearance, any sensation of mud. The lights of the range outweigh the shadows and the darkness is neutralized, helping to recreate a natural tone, but colder, somewhat narrower, but more vivid and of finer, delicate and higher tone. But this should not lead you to think that the ST-10S are sibilant at all, as they have good control in this sense, because the range retains a remarkable linearity.

Smabat ST-10S 15_resize.jpgSmabat ST-10S 16_resize.jpg

Treble

The upper area is not notable for its brightness, but for the amount of air. The highs are gentle, not too sparkling, but clearly noticeable. Its slightly cool character is due to this tuning of the high band. Without being totally explicit, the details are easily distinguishable, providing a good amount, especially at the macro level. There is no emphasis on this band, compared to the other two, but it is not neglected either. The highs maintain the profile that seeks neutrality, perhaps too much. They are fine and smooth, focusing more on producing a good amount of air, than showing a surreal amount of presence. Although, it is possible that some transients, towards higher levels, are perceived slightly sunken, diminishing some qualities and limiting a more uniform response.

Smabat ST-10S 17_resize.jpgSmabat ST-10S 18_resize.jpg

Soundstage, Separation

Another strong point of the ST-10S, is the great feeling of amplitude that they produce. Starting from the depth of the lower area, this new model presents, if possible, a wider, more extensive and longer stage. The three-dimensionality is perceived frontally, without being totally spherical.

The image enjoys very good positioning and the separation favours a wide range of details from all points of the scene. There is a remarkable degree of cleanliness and clarity, although the micro detail is simply good.

Smabat ST-10S 19_resize.jpg

Comparisons

Smabat ST-10

Comparison forced between predecessor and successor. I will skip the differences in packaging, cable, accessories and design and focus on the hearing differences. The first impression is clear: these are two different tunings, despite the aesthetic similarities. The ST-10 has a more energetic sound, in all bands, with a more noticeable low zone, a more advanced, warm midrange and more sparkling and vivid highs. In contrast, the S version has a less exposed sound, somewhat more backward, relaxed, not so much in the foreground. This happens in all its ranges, but it is especially noticeable in the midrange, where the voices don't have the weight, body and direct feeling that the previous version offers. If we analyze range by range, the S version, in its lower zone, has a remarkable width, offering well-drawn bass, more content, neutral, less swollen, with better control and more planes. In the previous version, the impact is greater, they are more extensive, with a slower decay, which provides a darker and more charged pose. However, the sub-bass, its power, sonority and naturalness, has not been overcome in the new version.

In the middle zone, again, there are clear differences. In the old version, it is somewhat influenced by the lower zone, because of its warmth and extension. In this way, the lower mid-range is fuller, with more body, presence and closeness. The S version, on the other hand, stands out for its greater neutrality, offering even a colder, thinner, clearer and more open tone. It is true that the proximity is also more relaxed, generating a less direct sound, but something more balanced, not as compact as in the previous version. Voices feel different: while the ST-10 sounds warmer and fuller, the ST-10S feels more liberated and less heavy, with more detail and a finer pattern, with a higher resolution and clarity profile. They are really two different proposals, but both have their great moments. For male voices I prefer the ST-10 and for female voices I prefer the S version.

Finally, the high zone has been redefined a lot in the S version. The previous model is much more explicit and free, generating more sparkling and marked highs. The S version has more control, and even feels a bit restrained, as its notes are more limited and contained.

The scene is presented differently in both earbuds. The more relaxed sound of the new version offers a wider scene feeling. While the old version, with its closer and more powerful sound, offers a more foreground representation, which is also not lacking in scene, but is demonstrated in other parameters, such as height. With all this, the stage feels more intimate in the ST-10, while the S sounds more open and ethereal, offering a more open and semi-spherical stage.

The better clarity and lower density of the S version offers a superior point of separation and instrumental recreation.

Smabat ST-10S 20_resize.jpg

Smabat M1

Without a doubt, one of the kings of value for money are the M1s. Its stubbier shape, a priori more uncomfortable, offers the best fit of the whole family, as its roundness and size, allows me a freer fit.

At a sound level, the comparison between both is more obvious. The ST-10S has an improved, enlarged and powerful low range, except in the sub-bass area. The M1, in the lower end, are more trimmed; but, still, its sonority is a little more realistic. The rest of the range is more innocuous, with simpler development, more limited presence and emphasis, more contained depth and less descriptive capability. With all this, the M1s retain a good colour and a pleasant, smooth texture in their bass.

The midrange presents a different exposure. ST-10S sound clearly more neutral and cooler. In the M1, the voices are more present and close, feeling fuller, due to its more central and warm profile. However, it seems that the details, instrumentation and overall recreation of the middle zone, enjoy greater resolution and amount of detail, in the ST-10S.

I find more coherence and balance in the upper zone of the M1. Its highs are more explicit and, although it has less air, they look more natural, since it lacks irregularities.

The little brother M1, can't compete with the amplitude of the scene of the new ST-10S. Comparatively speaking, the M1s are simpler and more limited in this respect, despite the cleanliness of their sound. The difference is clear, the sensation of width is felt from the first moment, observing a greater depth, quantity of planes, descriptive power and better instrumental recreation, as well as a more precise and defined global positioning. The separation also goes hand in hand, a bigger sound generates more silence and therefore an equal separation.

Smabat ST-10S 21_resize.jpg

Conclusion

Smabat is opening a coherent path. Its new models are not mere iterations, but seek to offer new sensations. This time, the ST-10S have taken the characteristics of the two previous models, to create a different tuning, which is halfway between both, gaining in scene and separation, but offering a unique sound and not continuous, aimed at neutrality. And there lies its virtue, since there are improvements, but also innovations and differences. And that is something I value, very positively, about this brand. We will continue, totally attentive, to the new movements of Smabat...

New Head-Fier
The day I received my pair of the original Smabat ST-10 earbuds was also the day I got a message from NiceHCK AliExpress store announcing these new versions and that they replaced the original earbuds that I had just got out of the mail.

Great timing NiceHCK!

I contacted them and they offered my some tasty discounts in the new models but given my finances and the huge delays getting items delivered and the fact that I didn’t need another set of earphones, I decided to stick with the set I had.

I’m extremely happy with them. They are definitely my best set of drivers. Very revealing and great sound stage.

Unfortunately they had one critical flaw. They created extremely unbearable hotspots on my ears.

I had the same problem with my old Apple AirPods.

But I persevered with them because they sounded so good. Initially I was trying to push them into my ears to get the best seal. When I stopped doing this and allowed them to rest in my ears I got longer usage from them but the hotspots would always return.

I think that the earbuds can move freely that may be allowing them to rub ever so slightly against my ears. Whatever to cause I finally found the perfect solution for me. With this I can listen for hours with them.

It’s a bit of a hack but I used some old AirPod ear tips with hooks to hold them steady in the ear.

This is what I have done:
  1. Use a hole punch to make an opening on the outside of the AirPod eartips
  2. Put the full foam ear cushions on the earbuds
  3. Put the donut cushions over the first cushions
  4. Put the AirPod tips over the the first two foam cushions

I had to use the two foam cushions to help keep the AirPods tips on better. It’s no perfect because they still come off sometimes when removing the earbuds.

hope this helps anyone that’s experiencing this comfort issue.

I also like my set a lot. You may like the M1 Pro from them as well. They are smaller and for me, not as warm after long sessions. You can also use the M1 Pro ear pieces on the ST-10 if you hang them down instead of over ear, just swapping the right and left positions. That really helps me get the best fit and comfort if I am moving around. I use both sets depending on mood everyday for my work. They are excellent. I am going to grab the new version eventually as well. Just not sure when that will be exactly.

Both the silver and gold ST-10s models have a longer acoustic tunnel than the older ST-10. Smabat claims this make for a better bass response. I don’t find problems with the bass in my set though, so I’m not sure how it could be any better than it is.

The silver ST-10s has impedance of 40 ohms, sensitivity of 115 dB and frequency range of 10 to 20000 Hz.

The gold ST-10s has impedance of 150 ohms, sensitivity of 115 dB and frequency range of 10 to 25000 Hz.

The older green ST-10 (the one I have with the shorter acoustic tunnel) has an impedance of 45 ohms and a sensitivity of 115 dB and frequency range of 10 to 22000 Hz.

So it appears that the older model sits somewhat between the two newer models.

I’m waiting on some reviews to see what these new models are like, just out of curiosity.

If the gold model is reviewed to be extremely good, I might consider a gold set in the future.

Though it’s unlikely because I’m extremely satisfied with my set right now. So the gold will have to be something special to get me to spend the extra to get a pair.
