Great detail & clarity. Fit took a long time to get used. Very clear and natural mids and treble. Lacks lower-extension, and couldn't handle bass notes on Time by Hikaru Utada (0:40+). Jays Audio Youtube Channel

2025-08-09Clean 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.
