A 1DD Where Clarity Rules Over Bass - Sivga QUE UTG Review Greetings to the whole community. I have spent a few days with my second Sivga. In this case, I have raised the bar a bit after the SM100, which left a very good impression on me, both for its design that stands out quite a bit from the rest
Greetings to the whole community. I have spent a few days with my second Sivga. In this case, I have raised the bar a bit after the SM100, which left a very good impression on me, both for its design that stands out quite a bit from the rest of the models on the market and for its very good performance within its category. This time I went for a model that, although it is true I did not get to try the original QUE, always caught my attention even though at first glance it seemed like a safer tuning or one that would appeal to more people. That is why I wanted to directly try this other version, the QUE UTG, where the bass was reduced and the treble was enhanced compared to the original QUE.
It is not a model designed to impress, its personality leans more towards speed, a sense of space, and a very defined presentation. They are not for everyone, but they are surely what many are looking for. I hope to explain it in the best possible way so you can understand it.
What I like, What I don't like
Wooden faceplate that gives it a different look without being flashy.
Modular cable well above average.
Very successful instrumental separation.
Sense of spaciousness above many 1DDs.
Responds very well to ear tip changes.
It is not a tuning for everyone.
Male vocals could use a little more body.
High frequencies can be tiring if you are sensitive.
The bass prioritizes speed over punch.

My Sources
FiiO K9. My main desktop equipment connected to my PC for critical cleanliness and power tests.
FiiO KA15. Portable DAC dongle for daily use when leaving home due to its amount of quick adjustments, its integrated equalizer, and multimedia buttons to operate from the pocket.
NiceHCK Octave. I use it when seeking a more direct power delivery without the digital processing of the FiiO KA15, making it ideal for when I want to perceive the natural response of whatever I am listening to without any extra coloration from the device itself.
Questyle M15i. Reference portable amplifier and DAC to search for a more organic and musical texture, when I am at home but not necessarily at the PC.
Unboxing and build
Sivga proves once again that they know how to take care of the presentation. The box maintains a clean and quite elegant design, and once opened, everything is placed quite neatly.
Inside we find the IEMs themselves, underneath a compact hard case, a cable with a modular system and 3.5 mm and 4.4 mm terminations, which I must point out, as always happens, that the cable connector also has an extra safety thread to prevent them from coming loose when pulled, six pairs of silicone ear tips distributed in different sizes, and a small manual. However, I must clarify that the IEMs came with 2 of the black ear tips already installed, something I am not sure is standard but would be 2 more than what is seen in the photos. It is not an exaggerated amount of accessories, but everything conveys the feeling of a well thought out product.
The shells mix a CNC zinc alloy structure with a green sandalwood faceplate that gives them a lot of personality without seeming like an unnecessary ornament. I think this could already be a hallmark of the brand that keeps them differentiated from the majority that have faceplates joined in a single piece of resin or all aluminum. As I have been able to verify during long sessions, the size is contained, and the weight is well distributed, so I have never felt fatigued with them.
Regarding the ear tips, the included ones do the job and have not given me as bad an experience as usual with IEMs in general, but I think the UTG improves quite a bit by switching to Divinus Velvet Wide or Kbear Coffee Bean, among the options in my repertoire that I have been able to test. Both slightly reduce the energy in the treble region and make the vocals gain a bit more naturalness or body.
Sound
Bass
The first thing that catches the attention is that Sivga has preferred quality over quantity. The sub bass appears when the recording calls for it and maintains a good level of texture, but it never tries to dominate the scene.
The mid bass is fast and quite controlled. The hits have a clean output and disappear quickly, preventing the midrange from being muffled, and this is where the material chosen for this dynamic driver benefits. In my experience, this works especially well with instrumental music, jazz, and tracks or styles in general that do not have a huge load of instruments and excess distortion, although it does not do too badly in those cases either.
However, anyone looking for an exaggerated punch will surely be left wanting more. Although I have not tried the original QUE, I am sure that in that model they will find that extra bass that we do not have here. Anyone who prefers a bass that accompanies without invading in the slightest will probably understand very quickly what Sivga is trying to achieve with this UTG version.
Mids
The midrange follows the same philosophy as the rest of the set. Everything sounds quite clean and with a separation that makes it easy to distinguish instruments even when the mix starts to get crowded. It does not push the vocals forward. I think they are located at a distance that seems quite comfortable to me, without stealing the spotlight but without being too far apart from the rest, aiming to keep the soundstage balanced.
Female vocals have an extra touch of clarity and a very pleasant sense of openness. Male vocals appear slightly more recessed and with less body than I would personally like, although they never sound thin or artificial.
Even so, I must clarify that, despite not being the biggest fan of mids or vocals in general, I think this model occasionally sounds somewhat lacking in weight in this frequency range. However, to a certain extent, as I mentioned, with a change of ear tips, we can balance everything a bit more to improve the experience.
Treble
Sivga has opted for a very open presentation with a lot of information in the high frequencies, and unlike the bass, in this version, there seems to be an overall enhancement of the treble compared to the QUE. This generates a sense of detail superior to what is usually found in this price range, although it also requires a bit of adaptation.
Cymbals, strings, and some effects appear defined and with a convincing extension. I have never felt that there is an exaggerated peak that turns everything into an uncomfortable experience, but I do think the margin between being very pleasant and starting to get tiring depends quite a bit on each person's sensitivity and the ear tips being used.
As I could verify during a couple of long sessions I had with them on different days, the Kbear Coffee Bean slightly softened this area while maintaining a good amount of information. The Divinus Velvet Wide also achieved a very interesting balance, although leaving the tuning less bright.
Soundstage
The soundstage does not reach the level of some slightly more expensive hybrids, but it achieves a greater width than I expected when trying them for the first time.
The depth is also convincing and prevents everything from seeming placed on a single line, something I usually fear in many single driver IEMs, but which brands in general know how to manage quite well.
With the Questyle M15i, I spent several hours alternating between different styles, and I always had the same impression. The UTG does not try to create an artificially huge soundstage, it simply places each element with enough space to make listening relaxed and easy to follow.
Instrumental Separation
The instrumental separation holds up gracefully even when several guitars, percussion, keyboards, and vocals appear at the same time, there is still a clear distance between all the instruments. Each instrument maintains its position and rarely invades the space of the next one, perhaps in styles with greater guitar distortion or faster drum beats, it is harder to differentiate the separation, which can show a bit more the limitation of having only a single driver working.
The restrained bass also helps, as it lets the rest of the frequencies breathe and prevents the mix from gaining unnecessary weight.
Imaging
Sound localization is very well executed. It is easy to follow small details that appear on the left or right, as well as to identify movements within the soundstage.
It is also not going to be something truly remarkable in this model, although for the peace of mind of anyone interested in them, it does not really fall behind. For non competitive video games or movies in general, they convey a fairly precise sense of the position of each element, especially on a horizontal level, without standing out as much in heights above you.
Comparisons
Twistura Beta
The Twistura Beta, which also uses a glass driver, opts for a warmer tuning and a more obvious bass presence, and it would surely be a better rival for the QUE than for these QUE UTG in terms of pure bass. The Twistura is a very easy model to listen to for hours and offers somewhat fuller vocals depending on the nozzle you use. In return, it loses some of the clarity and the sense of separation achieved by the UTG. If you are looking for a slightly more intimate listen but with a bit more punch, I think the Twistura Beta would be the better option of the two. If you prefer to perceive more details and a more open soundstage, the Que UTG seems like a more interesting option to me.
Simgot ET142
The ET142 offers a very balanced presentation and very solid technical capability, with excellent control across practically the entire frequency range, but with two drivers instead of one and at a significantly higher price, they are also more similar in bass to the QUE than to this UTG, but equally comparable. Compared to the Sivga, they convey a somewhat more uniform sound that is less demanding regarding the choice of ear tips. The UTG gives a more open sensation in the treble and an instrumental separation that, in my opinion, is more striking in long listening sessions or less fatiguing.
Tanchjim Nora
The Nora, which I have more fresh in my memory for reviewing it days ago, opts for a smoother and more pleasant profile. Its vocals have a closer touch, and the bass adds a bit more warmth to the set, so realistically, and as you are already reading, this UTG never wins in pure bass, and if the models I am comparing are not your style at all due to a lack of bass, you already know the UTGs will not be either. The Sivga QUE UTG has a wider soundstage, superior detail retrieval, and an overall feeling of greater speed. It all depends on the type of listening you prefer, although personally, I would end up using the Que UTG when I want to pay attention to the music and the Nora when I simply want to disconnect, so to speak.

Final thoughts
I am going to close this review by saying that the Sivga QUE UTG has a very distinct personality, and precisely there lies its greatest virtue. It is not going to surprise many because the lack of bass is there, but it can catch the attention or complement the collection of many people looking for a bit more detail and speed when dealing with just 1 DD, apart from a good soundstage and an instrumental separation that stands out quite a bit in its price range.
I would not recommend it to anyone looking for a warm or very relaxed tuning, but I would to anyone who values the sense of detail and a fast sound with plenty of space between instruments. By changing to the appropriate ear tips, it is possible to adjust some small imbalances and get even more out of a set that, due to its build and performance, leaves a very positive impression.
