Simgot SuperMix 4 Review: An Excellent Exotic Mixed Salad

Disclaimer:

Good morning, Readers! Today we are going to look at the Simgot SuperMix 4. Following the EM6L, EW200, EA500LM, and EA1000, comes the SuperMix 4.

I believe the Simgot SuperMix 4 is a solid upgrade to the EM6L; in fact, the design appears to be a continuation of the former.

Simgot has decided to propose a very interesting hybrid configuration, a sort of mixed salad with an excellent selection.

I’m not an audiophile; I’m just a guy that likes to test out different IEMs and DACs and spends a lot of time listening to music. I fall into the audio enthusiast category.

So I’m not going to use super-technical words to review it, but I will do my best to describe it.

Tech Specs:

First look

The Simgot SuperMix 4 comes in a metallic green package with a graphic representation of its internals. When we slide the cover, we can already see the SuperMix with the following accessories:

All accessories
Case + cable + tips
Litz Cable
Strains
Terminals 0.78mm
07 tips

The hard case with the gold-colored zipper is an unexpected touch of class. Beautiful to look at. The included cable is not particularly thick but is advertised as Litz and should be of good quality. Unfortunately, it is not balanced. Tips 07 are, as usual, the best stock tips.

Design/Build Quality:

In my opinion, the Simgot SuperMix 4 takes up the design of the EM6L, a slightly different style from that proposed for the others with a single driver. I think the choice of resin and 3D printing is mandatory in the presence of multiple drivers to facilitate the internal structure. The aesthetic choice is even simpler than the EM6L. 

Simgot SuperMix 4
Front & Back
Shape
Really simple faceplate
Really dark/purple resin

Inside, we find 4 different drivers per side, managed by a 4-way crossover:

Metal vent
Venting near the pin
Faceplate
engraved ring + vent
Vent detail
Nozzle macro

On the gunmetal faceplates, there is only a gold/copper colored ring. Without logos or writing that refers to the brand. Even on the resin, we only find SuperMix 4. The structure is a little thicker (it must accommodate 4 drivers per side), but the ergonomics and shape are some of the best. The nozzle is quite wide, but I’ve seen worse. I would define it as medium in size.

We have two ventilation holes, one located on the faceplate where we glimpse a metal grill, and the other located towards the other near the connector.

The construction quality and general solidity seem superior to me than the EM6L, and this is excellent news as many have had some problems with the nozzle coming loose.

Initial sound impression:

At first listen, the Simgot SuperMix 4 surprised me both positively and negatively. Let me start by saying that in a hurry, I took my Poco M4 Pro and the Fiio KA11, which perhaps is not the most suitable dongle. I believe this combination, plus the mood I had at the first listen, influenced the first impression a lot. The timbre seemed unnatural to me, with some elements, especially in the mids, bordering on artificial. Also, thanks to the mood lately, the music sounds different and almost always sounds worse. But when I started listening again the next day on the PC with the EPZ TP50, things immediately changed for the better. I finally feel its potential, and in a certain sense, the artificial touch has remained, but in a much lighter way. Surprising for the amount of micro details and separation of sounds.

Comfort & Fit:

In terms of shape, it is more similar to the EM6L; the comfort is absolute; and the stability is also better than the models with metal shells. The lightness factor also helps a lot. As for the tips, the standard ones are excellent, but in my case, I had some problems in terms of sealing. I believe that such an elongated nozzle deserves tips capable of a slightly deeper insertion.

Tips Rolling?

Tips Rolling

The Simgot Supermix 4 comes with the 07 model tips, which, in most cases, work very well. However, I always noticed a slight difference in bass on the left ear, so I decided to do some tip rolling, which, to be honest, ended very quickly.

On my first try with the Divinus Velvet Tips, I noticed excellent comfort, especially if you choose a size that allows for a slightly higher insertion than normal. However, their finish allows for pressure relief in the ear canal, but in the case of the SuperMix 4, it seemed excessive to me. Clearly, the vents in the shell are already doing their job well, resulting in loss of low range, more dispersed bass, and shriller highs.

I skipped the other tips because they were similar to 07, so I went straight to the wide bore. I could have chosen between Tangzu Sancai, SS20, and Tri Clarion, but I skipped the first ones because I would already found the IEMs they should be on. The Tri Clarions would probably have increased the treble, so I switched to the sand/human skin colored SS20 tips, which are slightly smaller than usual, have deeper insertion, and perfect sealing. The bass are back finally!

Equipment used for testing the above:

Device:

Software:

DAC:

Front Simgot DEW4X

I did about 12 hours of burn-in at a fairly high volume. I can’t tell you exactly if there are improvements, as I changed the tips, and that’s what definitely improved them compared to the first listen. Plus, there are the usual brain and mood factors that make you both adapt and perceive things differently.

Final sound impression:

The Simgot SuperMix 4 is definitely an interesting hybrid; the driver configuration is very spot-on, and the tuning is very good. After careful listening, they are definitely better than the Simgot EM6L (which, however, remains excellent for the price). The difference lies above all in separation, layering, and details. In terms of tuning, they chose the 2019 Harman curve. The only thing is that perhaps the midbass is a little shy and the tonality tends to have a cold touch, which affects the mids and therefore the voices, which are sometimes a little metallic. I believe that, with the right tips, this perception can be greatly reduced. With perfect sealing, the bass can compensate for the tonality.

I would have told you to try using slightly warmer sound dongles, but that’s not necessarily the best result. Given its slightly cold tendency, as anticipated, I carried out a first listen with the Fiio KA11, but with a good but not excellent result. It’s definitely better with the EPZ TP50 and the Simgot DEW4X.

360 Overview

I would have told you to try using slightly warmer sound dongles, but that’s not necessarily the best result. Given its slightly cold tendency, as anticipated, I carried out a first listen with the Fiio KA11, but with a good but not excellent result. Definitely better with the EPZ TP50 and the Simgot DEW4X (slightly better).

But the one that really gave its best in the economic range of dongles was the Fosi DS2 (same thing for the iBasso DC04Pro).

Bass

In terms of bass, especially the mid-bass section, it is a little shy, the extension of the sub-bass is good and dense, the texture is excellent, quite fast and precise, and the dynamic driver only deals with the bass. I think perhaps it could also be something more, but being faithful to the 2019 Harman curve, this is the best that could be achieved. The important thing is not to lose details with the wrong tips.

Using the SS20 tips, the bass gained fullness and definition. You can see how the separation from the other frequencies is clear and clean.

Mids

As for the medium frequencies, the balanced armature takes care of them; this could be one of the many reasons why they sound a little cold and metallic. They are certainly not the queens of naturalness, but I can assure you that the details are truly surprising; the separation is absolute, but they appear slightly in the background. The presence of air in the mids is absolutely incredible, plus there is a lot of musicality, which makes them very attractive even if the tonality would have been slightly warmer. Perhaps it could have been compensated with a fuller and less damped lower midrange.

You will notice this, especially on certain tracks and female vocals.

Treble

The planar and piezo drivers work exceptionally well as a team. The presence of air and micro details is notable, but unlike the usual Simgots, I find these much more tolerable and contained, but the presence of this type of driver does not make it lack anything in this region despite being much less pungent. Occasionally, on some tracks, I’m a little on the edge. Track after track, these ultra-defined and well-arranged sparkles on the soundstage literally make you fall in love.

Soundstage and Imaging:

The soundstage is recreated in a large and faithful manner thanks to the precise arrangement of the sounds, and the image is extremely detailed and precise, making the Simgot SuperMix 4 also suitable for gaming like its predecessors. Each sound has its own dedicated track, which reaches the eardrum in an undisturbed and clean way, which is why I also recommend wide bore tips.

 The peculiarity of being so transparent and detailed helps without a shadow of a doubt; their technicalities for those who have already had the opportunity to listen to Simgot products are at the height of their other products.

Comparison:

It is definitely difficult to make a comparison with DD singles, but I will try, in any case, to make as many comparisons as possible. Simgot, with the SuperMix 4, has raised the quality of hybrids in this price range.

vs Simgot EA500LM

Simgot EA500LM

Some people prefer the Simgot EA500LM, so who am I to tell you which one to buy? Yes, I am nobody! As far as I’m concerned, the resolution is on another level, the difference is certainly more marked than the EW200 and the EA500LM. There is a difference but the tuning and sound signature are the same so unless you are so attentive to detail, you can easily stop at these. Furthermore, if you don’t have both, you can’t say which is better. Are you ready to shell out 400 USD?

.

vs Simgot EA1000

Simgot EA1000

The Simgot EA1000 is a completely different type, a quality single driver responsible for all frequencies, If you own both, you will immediately notice the difference, especially in terms of soundstage, directionality, and separation. The Simgot SuperMix 4 in comparison gives you many more details and greater precision, even if, in terms of tonality, the EA1000 is superior to it.

vs Simgot EM6L

Simgot EM6L

The Simgot EM6L to date is still one of my favorite birds, even if many don’t appreciate it that much. The voices are slightly less cold, just enough to make them more natural. In terms of tuning, there is a notable similarity with the SuperMix 4, which, however, fares better in terms of airiness, details, and separation. The EM6L are slightly richer in energy and musicality.

vs Hidizs MS5 & MS3

Hidizs MS5
Hidizs MS3

The MS5 has stronger bass, but at the same time, the trebles become very aggressive and are not easily tolerated, I think the level is beyond even the brightest Simgot. In terms of tone, I think the MS5 is slightly more correct, but at the same time, the trebles dampen the enthusiasm.

The MS3, on the other hand, is calmer when it comes to trebles and is more tolerable and coherent than its older sister. In terms of sound performance, they are much closer to the SuperMix 4, even if they lose some points in separation and detail. They gain something in terms of bass and tonality of the voices. After some time, I have to tell you that I prefer them to the MS5.

Conclusion:

I think the Simgot SuperMix 4 will become one of my reference hybrids, Even if the tone could be warmer, its technical aspects make it even better than more expensive hybrids. Track after track, different musical genres—the representation of the genres I listen to is more than satisfactory.

But don’t worry, it’s not absolutely cold or metallic and only slightly thin in the mids. For what it’s worth, it’s excellent by my standards.

In conclusion, this mixed salad of drivers made by Simgot is a very respectable result. An IEM that makes you rediscover some tracks you hadn’t noticed any details about is always very welcome. I would have appreciated at least another type of tip included in the package and the possibility of choosing a balanced 4.4mm terminal. Personally, I would have also liked a transparent variant similar to Celest Phoenixcall.
