In today’s article, I review the SIVGA Que UTG. Compared to the original model, the Que UTG utilises a flat glass diaphragm and South American green sandalwood faceplates. It’s priced at 97 USD.

Design

The Que UTG’s distinctive faceplates are crafted from South American green sandalwood. Not only do they help reduce resonance, but they also give each set a unique wood grain pattern. The metal shells look and feel premium, with a smooth, polished finish that adds to the high-end aesthetic.

There are two pinhole vents on the inner side of the shells to relieve pressure and prevent that uncomfortable “plugged” sensation. The shells themselves are reasonably small and ergonomic, with rounded edges that make them extremely comfortable—even during long listening sessions. Passive noise isolation is solid, and there’s no noticeable noise leakage.

Internally, the SIVGA Que UTG houses an upgraded, glass diaphragm dynamic driver. This innovative diaphragm is extremely lightweight yet highly rigid, which helps reduce distortion and improve transient response. The UTG diaphragm is manufactured by the Japanese firm NEG.

As well as the diaphragm upgrade compared to the original Que, the included 0.78mm 2-pin cable has been improved too. It’s now modular and comes with both 3.5mm and 4.4mm connectors. Furthermore, the new cable has a 4-strand construction, is more supple for better handling, and feels more premium in the hand.

Sound

Sources used for testing include the D&A Alpha Pro, iBasso DX180 and Moondrop Moonriver 2: TI. Que UTG is efficient and easy to drive, so there’s no need to pair it with an expensive or powerful source.

The SIVGA Que UTG takes a unique approach with its tuning, steering clear of the Harman and Meta target responses. Instead, it delivers a sound with a strong focus on the midrange with an extended treble.

Bass

The Que UTG does the opposite of what many recent IEMs have done—it rolls off the sub-bass and boosts the mid and upper bass. This gives the overall sound a rich, warm character. It’s a risky tuning choice that could easily turn into a bloated mess, but thanks to the high-quality driver and strategic treble tuning, the Que UTG pulls it off handsomely.

While the sub-bass has a lighter, more restrained rumble, the mid-bass is punchy and full-bodied. Kick drums have a slightly softened attack for a more natural feel, but the quick decay and tight control keep things snappy and prevent any looseness. Bass guitars get a lot of love, as do cello and lower piano notes, which come through with satisfying warmth and density.

Midrange

The lower midrange is rich and saturated, compliments of the boosted mid and upper bass. Male vocals and bass instruments sound powerful and thicker than neutral but never congested. There’s a slight lift in the upper mids as well to compensate for the extra warmth and maintain clarity. Despite the thickness of the lower mids, vocals and instruments don’t sound blurred or veiled, thanks in part to the quality of the driver and the treble tuning.

Treble

The Que UTG’s treble is cleverly tuned to counterbalance the warmth in the lows, adding clarity and keeping congestion at bay. Impressively, it manages this without sounding edgy or sharp. There’s also plenty of air and detail on offer, with no sibilance or noticeable brightness. Maybe that fancy glass diaphragm really is doing something special. The treble sounds more natural than the majority of piezoelectric drivers I’ve heard. It’s crisp yet smooth, with no metallic or unnatural character. In fact, the treble timbre is above average for a sub-$100 IEM.

Soundstage & Technicalities

In short, I’d say the soundstage and technical performance of the Que UTG are much better than I’d normally expect for such a tuning. Despite the warmth and richness of the upper bass and lower midrange, the Que UTG has an impressively wide soundstage, great clarity and good resolution. Detail retrieval is excellent, even better than a lot of the direct competitors, which is unusual for IEMs with a warm tonality.

Comparisons

Sivga Que

The original Sivga Que has more emphasis on the sub-bass with less fullness in the upper midrange and a more rolled-off treble. Its tonality is somewhat similar to the Que UTG—clear with warm undertones but slightly less dynamic.

Vocals sound leaner and have a thinner note size, whereas the Que UTG is unapologetically more saturated and emotive. The Que’s stage is slightly wider, but it feels flatter front-to-back—more like a broad, shallow venue than a deep, rounded one. Both of these IEMs perform very well for their respective price points but the Que UTG’s upgraded cable adds extra value, in my opinion.

Truthear Pure

The Truthear Pure leans closer to a neutral tuning with less warmth in the mid-bass and a leaner overall presentation. While both aim for clarity, the Pure achieves it through a more linear approach, whereas the Que UTG sculpts a richer tonality.

Vocals on the Pure are more articulate but can occasionally sound leaner next to the Que UTG’s more expressive and full-bodied character. The soundstage on the Pure is slightly deeper and more focused, while the Que UTG has a broader lateral spread and feels more open overall. Both offer strong value in their respective price ranges, but they cater to different tuning preferences.

Verdict

The Que UTG stands out not just for its sound but also its unique aesthetic—those wooden faceplates give it a distinctive, natural charm that sets it apart from the usual crowd. Sonically, it’s a refreshing alternative to the countless Harman-inspired tunings out there, offering a richer, more emotive presentation. If you’re after something with character both in design and sound, the Que UTG is well worth a look.
