Review - Simgot Supermix 4

TLDR version on YouTube: TDLR - Simgot Supermix 4

The Supermix 4 have been sent to me by Simgot in exchange for the publication of this review. Simgot have not requested anything or made any comments and, as always, I will do my very best to be unbiased in my review of these IEMs.

There doesn't seem to be an official page for the Simgot Supermix 4, at least I haven't found one, but they are available from the usual online stores. A quick search online will bring back plenty of results to choose from.

Intro…

I have to start off by saying that I am very happy to review these IEMs. As I mentioned in my last Simgot review, and probably in other reviews of Simgot IEMs previous to that one, I have really wanted to like a set of Simgot IEMs.

By that I don’t mean that I don’t think that Simgot make good IEMs, all of the IEMs I have received from them have been good, but I have struggled with all of them to some extent or another. The EA500LM, my last Simgot review, was the set that I have enjoyed the most to date but, even then, I would still not say that they are for me.

I have to give credit to Simgot for reading each of my reviews, saying thank you and moving on without a single complaint. It is not that my reviews of Simgot have been negative but there are a lot of brands who take offense with comments that are not along the lines of “these are the best ever” and no longer contact me to review their IEMs. That is something that Simgot have never done, in fact, they have continued to send models until we are where we are today.

Now, looking at the tuning of the Supermix 4 on paper, I would have said that these IEMs are probably the tuning from Simgot that I would most dislike out of all of them. I know I am jumping the gun here, I will get to audio impressions in a moment, but this is another one of those cases that proves that my preference target is nothing but a squiggly line that has no impact on whether I will like or dislike the sound of an IEM. But anyway, more on that in a moment, let’s first mention briefly what the Supermix 4 are.

Featuring four drivers in a hybrid set up, consisting of a dynamic driver, a balanced armature, a planar magnetic driver and a piezoelectric driver, there is a lot to go wrong when trying to make all of these play together in a coherent way.

According to the publicity, they are using the 10mm DD for the low frequencies, the BA is being used for the mids and the Planar+PTZ are being used for the higher frequencies. They are priced at around 140€, a price that I feel is more than reasonable for what you get, so let’s see what it is that you actually get.

Presentation…

While the outer box is not the usual style we get from Simgot, the packaging and contents certainly are. The outer sleeve is green and shows an x-ray style image of the IEM on the front, with the frequency response graph and the specs shown on the back.

Removing the sleeve reveals an inner box with a flip open card style lid, something very common on Simgot packaging, which opens to show the IEMs in foam cutouts and the usual accessories box below. Underneath the IEM section, we get the second box which contains the included tips.

The tips are the usual ones that Simgot includes, nothing extraordinary but I have, as always, used them for this review. The included cable is rather nice, with an outer texture that is a little rubbery to the touch but nowhere near like cables from other brands. It is stated to be an oxygen-free copper silver-plated cable, if you are interested in that kind of thing. All I know is that it works and is quite nice.

The storage transport case is also the typical oval shaped non-branded case we have seen in other Simgot packages, again nothing special but more than enough to protect the IEMs when storing or transporting.

In general, the contents could be considered a little sparse at the price point in comparison to other brands but it is the usual content from Simgot (except for no additional nozzles with this set, something I am actually happy about 😉) so it is no worse (or better) than other options from the brand.

Build and aesthetics…

The shells are simple black 3D printed shells with a dark grey metal (I think it is metal) faceplate. The faceplate has a simple circle on it in a goldish colour, depending on light, making them very simple overall. These are not the typical fingerprint magnets from the brand, no mirror finish which can look great but also be a curse if you are someone who hates fingerprints. Here we have something that does not show signs of use at all, at least in the time I have been using them.

The size is around average, not overly large but certainly not small and the fit is comfortable for me personally, being light weight also. Due to the length of the nozzles, I have found that I can use both medium and large size tips with these IEMs, getting a seal with both. After some listening, I found that I preferred the larger option with the IEMs getting just a couple of mm less insertion but both work.

The cable, as I said above, is quite nice and has metal hardware that matches the faceplate of the IEMs, so, while nothing extraordinary, I am quite happy with the overall aesthetics of the Supermix 4.

Sound…

If you read the intro, then you already know that this section is going to be positive. However, before getting to the subjective bit, here is the graph of the Supermix 4 in relation to my personal preference target:

Ok, so I enjoyed using these for general listening for the week I used them but let me share my opinions on these IEMs while sitting down with my usual test track list and focusing on specific tracks and performance.

As always, let's start with the “Chameleon” subbass torture test. There is a lot of subbass here and, to be honest, it can become a little much unless you are someone who likes a lot of rumble. The driver does a good job of presenting the track, although I do feel that it is a little overwhelmed by the brutality of the bass when it is in full swing. By this, I don’t mean that it sounds bad, far from it, it proves to be a very capable driver in the lows, it just suffers slightly when driven to the limits.

Moving on to something that is still bass but in a much more sensible way, “No Sanctuary Here” sounds very good on the Supermix 4. There is plenty of subbass and midbass without ever getting the sensation that the driver is suffering at all. There is a very nice cleanliness to the bass hits, while not really over shadowing the rest. Yes, there is an emphasis on those lower notes but they are not stealing the show from the rest of the track, they just sound very full and capable.

The low end reverb in “Crazy”, something that easily fatigues me if overdone or not 100% clean, on the Supermix 4 sounds very clean and pleasant. There is again a sensation of the low end having a great “body” to it but without seeming overdone and keeping it clean and articulate. There is also no harshness or sibilance to Daniella Andrade’s voice in this track, something that does appear on a lot of sets. While there is definitely a bit of a focus on the lows and the upper mids, I find the track to sound very pleasurable on this set of IEMs.

Even though there is that V shaped response to these IEMs, it does not overpower the mids completely and I find it does an excellent job of reproducing “Sun Is Shining”, where the electronic bass is definitely the strong point but the rest of the track is still clean and by no means eclipsed at all.

Another track that shows the capability of these IEMs to reproduce a good low end without taking away from the clarity of the rest of the song is “Elephants on Ice Skates”. The bass plucks are clean and articulate, the brass sections are not overpowering and the the actual low bass notes are full and smooth.

There is a nice sensation of treble extension and air without it sounding artificial. While the Supermix 4 may not be the most detailed of IEMs, it doesn’t try to artificially create a sensation of being more detailed than it actually is, meaning that there is no overly pushy upper treble that tries to make the details stand out. That doesn’t mean that they are lacking in detail, they do a more than respectable job, they are just not something that is focused on making detail the forefront of the experience.

The soundstage is not huge but there is a nice separation between the instruments and vocals inside that stage. That also goes for the layers of vocals in things like “Strange Fruit”, where they different voices are identifiable but are not really separated, more of a chorus effect than individual vocals.

Conclusion…

This is the review that I have been hoping to do of a Simgot product. I have been wanting to really like a product of theirs and the Supermix 4 is finally it. For once my conclusion isn’t “they are good... but…”

The fact that I have been wanting to like something from Simgot may mean that there is some subconscious bias on my behalf, which I have tried to avoid but can’t guarantee that it isn’t there. Saying that, I also wanted to like previous models and it has taken until the 6th model I have tried to actually get there, so a “thank you for your patience” goes to both Simgot and you, the reader!

I find the Supermix 4 to be a very pleasurable IEM that I wouldn’t say is the best at anything in particular, but it does a good job at everything. It is a set that I have really enjoyed using, no matter what music I have decided to listen to, and feel that it is certainly something that those looking for a general all round set to enjoy music should take a look at.
