Master Tuning Makes more Perfect Sound Quality

Xie Yu, the former tuner of Fostex, led the tuning of QT series who has participated in the tuning of various classic models like 1E7, MX980, A8. His tuning style, which is typically characterized by high vocal density and high resolution, has always been relatively balanced. QT-X is a masterpiece that took Mr. Xie 3 years to adjust.

QT-X is the new generation of flagship earphones of QT series, designed to benchmark the market mainstream flagship earphones priced at ten thousand yuan. QT-X has unparalleled resolution quality: the DD+BA configuration generates a grand soundstage; two medium-frequency BA drivers make it have a very high-density vocal performance. The 8mm Testa DD makes it easy to get low-frequency dynamics. The dual high frequency BA drivers make it obtain excellent extended sense of treble performance. As a flagship, it's balanced but not mediocre.


Ergonomic Design

It is more in line with the ergonomic design of European and Asian ear canal, which took more than 70 times appearance adjustment for comfortable wearing and collected more than 200 groups of 3D data of European and Asian ear.
