Disclosure: I’d like to thank Sivga for sending me the Que UTG for this review. All thoughts and opinions are my own, and Sivga had no say or input on the contents of this review.

The Sivga Que UTG is Sivga’s latest IEM, featuring a 10mm flat glass diaphragm dynamic driver, hence the addition of UTG (Ultra Thin Glass) to the name. The price is set at $89 USD, which is $20 more than the original Que released for, which would mean that this new driver should be an improvement over the original. That will be the big question I will try to answer in this review: Is the Que UTG an upgrade over the original Que, or merely a sidegrade with a higher cost? Let’s get into it and find out.

• Sivga Que UTG
• 1.25mm cable with interchangeable termination
• 3.5mm connector (pre-installed)
• 4.4mm Balanced connector
• Two sets of S, M, L silicone eartips
• Leather storage case
• Manual

Sivga has never been one to be stingy with their accessories, and it is no different with the Que UTG. Along with the IEMs, we get a very nice 1.25mm silver-plated OFC cable. The cable has a modular end, and Sivga includes both a 3.5mm SE and a 4.4mm Balanced connector. The cable itself is decently thick and very flexible, with a smooth plastic feel it it. The cable is very nice, really.

Two sets of S, M, L silicone eartips are included (a pair of black M tips are pre-installed). The black colored set is very thin and flexible, with the clear set being more sturdy. I preferred the feeling of the clear eartips due to their rigidity.

Lastly, the leather zipper case is the same as what you usually get with Sivga IEMs, which means it is very nice, roomy, and very high quality. It’s one of my favorite cases for IEMs, and the aesthetic gives it a real classy look.

The Sivga Que UTG features a faceplate made of South American Green Sandalwood protected by a glossy surface. The wood’s pattern is unique, so every Que UTG IEM will have its own unique pattern. The shell is made of a zinc alloy and has a very smooth finish to it. On the inside portion are two acoustic vents for airflow. The silver shell and woof faceplate provide a striking look, in my opinion, which helps the Que UTG stand out from your typical resin shell designs.

The 3D design of the shell allows it to fit comfortably in the ear. I had no issues getting a decent seal, but isolation is not as good as other IEMs. The passive noise isolation is just average. Despite these IEMs being on the heavier side at 10 grams, I did not encounter any ear fatigue or discomfort. The two pressure vents I mentioned earlier prevent any sort of pressure build-up in the ear canal, so I would say it works very well.

The Que UTG uses a recessed 0.78mm 2-pin connector, and each shell is labeled L and R, which I always appreciate. Used with the included cable, there is no microphonics to speak of, and the cable’s ear hooks do not drag down or dig into the back of your ears. Comfort and look-wise, the Que UTG really doesn’t do anything wrong, and gives you an absolute complete package here

The Que UTG features a flat glass diaphragm with a flexible PU surrounding that is said to deliver exceptional responsiveness and precision. At 32 ohms impedance and a sensitivity of 103 dB, it is not hard to drive at all, but I find it benefits from having a slightly higher powered source. Meaning, it will sound just fine as a basic dongle DAC, but giving it more power from a DAP or portable DAC/Amp does add something meaningful to the sound quality. Despite including a 4.4mm Balanced connector, I never felt the need to use it, and noticed no differences when listening between both connector types.

The Sivga Que UTG has a sound signature that is more U-shaped than V-shaped. It has an emphasis on the upper midrange and treble, with a slight mid-bass focus to help balance out the sound. It does lean more towards the neutral and analytical territory, and brings a musical and lively sound.

Bass

The bass response of the Que UTG is tight and controlled. It doesn’t deliver overwhelming sub-bass, but it does provide a satisfying punch that complements most tracks I listen to. The mid-bass is particularly well-defined and present without bleeding into the midrange or overwhelming the rest of the mix.

The bass is also very responsive and has a fast attack, most likely thanks to the flexible PU surrounding. The bass is overall more quality than quantity, which helps with critical listening but will leave you unsatisfied if you want that punch and slam. For me I like this type of bass response in general.

Midrange

Vocals are presented with clarity and warmth, making them a joy to listen to. Male vocals do suffer a bit as the lower midrange is slightly recessed, so they lose some body and texture. I’d prefer them to be thicker, but really, they sound just fine. The upper midrange is slightly elevated, which enhances the presence of female vocals and instruments. This tuning brings some energy, allowing the vocals to be lively but not shouty. Guitars sound fantastic, and the layering is detailed enough for critical listening and musical enough for casual listening. I really like the overall clarity here.

Treble

The treble performance of the Que UTG is impressive, thanks to the flat glass diaphragm. The highs are crisp and detailed, providing a sense of airiness without becoming harsh or fatiguing. This balance makes the Que UTG suitable for long listening sessions, as it avoids the piercing highs that can be uncomfortable to listen to. On bright tracks, it might sound just a bit too spicy for some, but I didn’t have any issues.

The emphasis on the treble might be my favorite aspect of the Que UTG, as it brings a good amount of energy to the music and doesn’t sacrifice any detail or texture. For a single DD IEM, it has excellent performance here.

Soundstage and Imaging

The soundstage of the Que UTG is surprisingly expansive for a single dynamic driver IEM. Instruments are well-separated, allowing for an immersive listening experience. The imaging is precise, making it easy to pinpoint the location of different sounds within the mix. I feel like a single DD IEM cannot get any better than this, especially at this price point.

Gaming

The excellent technicalities of the Que UTG allow it to be a great gaming IEM. Since it leans neutral and has analytical qualities, it performs very well with competitive multiplayer games like Call of Duty and PUBG. Footsteps are generally easy to hear and pinpoint, and the spatial performance is very good thanks to the expansive soundstage and precise imaging. I didn’t feel a need to use EQ as it has just the right mix in my opinion.

Both the original Que and the Que UTG have a similar design and use the same shell materials. The main differences are the internals. The original Que uses a 10mm beryllium-plated diaphragm dynamic driver vs the 10mm flat glass diaphragm in the Que UTG. This results in what I feel are very different sound signatures.

The original Que is warmer, has a more elevated bass response that results in more impact and rumble. This helps vocals sound thicker and even richer than the Que UTG. The Que UTG is more neutral and analytical, sacrificing the bass response for a cleaner sound that is detailed yet still musical.

For the music that I listen to (which is linked above in the Sound Quality section), I prefer the sound profile of the Que UTG.

The Sivga Que UTG is a very capable single DD IEM. At $89 USD, it offers a very compelling package and delivers excellent sound quality that works very well with most genres. On top of that, I feel it is definitely an upgrade over the original Que. I do appreciate that Sivga chose to differentiate the sound profile between the two instead of doing a very subtle and mild incremental upgrade. In a way, I feel the Que UTG is actually worth purchasing even if you own the original Que, since the tunings are very distinct from each other. If you don’t own the original Que but are simply looking for an IEM that is under $100, is versatile, and sounds great for both music listening and gaming, I think the Sivga Que UTG is very hard to beat at this price.
