Clean neutral nice mids. This iem is dumb, just buy it. Jaytiss Youtube Channel
The YU9 Que sports a premium, durable resin shell in pure black with a metallic-feeling faceplate and a comfortable design featuring an anti-tragus catch. While the build itself feels handsome and unique, the included cable is criticized as wimpy and unpleasant, with a strong suggestion to upgrade it. Accessories are deemed solid, including a nice selection of tips and a particularly praised case with a soft, luxurious interior.
Sonically, the YU9 Que earns immense praise for its exceptional tuning, described as clean, resolute, and non-fatiguing. It delivers strong, textured bass that avoids being overwhelming, coupled with extremely well-done upper mids. While not class-leading in technicalities like micro-detail or instrument separation, its tonal balance is considered sophisticated and reminiscent of far more expensive sets like the Annihilator, even surpassing the Monarch MKII in tuning preference. It's highlighted as a fantastic all-rounder with a smooth, agreeable signature suitable for long listening sessions.
Despite its modest single dynamic driver + 3BA configuration and $49 price point, the YU9 Que is declared a very special and unique IEM, worthy of the hype it received. The review concludes it's a price leader and a highly competent package from a small brand, offering outstanding value and a beautiful, well-executed design that makes it an easy recommendation for those seeking a smooth, non-fatiguing sound.

The YU9 Que is a hybrid IEM using 1 dynamic driver + 3 balanced armatures, positioned in the mid-upper price tier with an MSRP around $399. Retail listings confirm the configuration (10 mm LF DD with three Knowles BA units) and current pricing in USD and MYR, placing it among competitors that emphasize tonal refinement over sheer technical fireworks.
Community impressions describe a balanced/neutral tonality with a tasteful bass lift, smooth upper-mids that avoid glare, and treble that leans non-sibilant. Subjective reports on Head-Fi and Reddit consistently frame the Que as an all-rounder that favors coherence and long-term listenability over maximum micro-detail.
Technically, listeners note solid imaging and macrodynamics with competent detail retrieval, though not class-leading for the price. The manufacturer has also published frequency-response plots (IEC711 and BK5128 rigs), which aligns with the community’s take that the Que targets a broadly neutral/balanced signature rather than an aggressive V-shape. Overall value is credible at its MSRP if you prioritize tonal balance and comfort over ultra-analytical presentation.
