For over three years, the Spaceship has been widely praised for its light design, comfortable fit, and superb sound performance.

As a worthy successor to the Spaceship, the "Chu" has adpoted a completely different design concept, a more traditional Chinese styling, and more significantly up-graded acoustic architecture.

Descriptions:
>10mm Composite Cavity Dynamic Structure

Adopting the Aria's decentralized dynamic stucture, the high-performance 10mm composite cavity with high frequency phased waveguide leverages a N52 Nd magnet internal magnetic circuit and 0.035m ultra-thin imported CCAW sound coil to obtain high energy conversion efficiency, and deliver outstanding performance with full dynamic range and rich details.

>Accurate Calculation of Acoustic Coupling Cavity

In order to match the frequency response as closely as possible to the VDSF Targe Response[1], the acoustic coupling cavity needs to be carefully controlled. Through volume and dimension calculation, FEA finite element simulation and 3D priting experiment verification, an acoustic coupling cavity has been created which can accurately reporduce the ideal frequency reponse.

>Frequency Response
Chu produces an excellent frequency response curve in line with the VDSF Target Response[1]. This outstanding frequency response curve gives "Chu" the ability to faithfully reproduce the sound heard by the sound engineer when making recordings. Compared with other earphones, "Chu" is able to more truly reveal the original timbre and position of musical instruments and vocals. It not only delivers a more open and natural listening experience, but also meets the needs of recording and mixxing professionals.

>Alloy Casting External Cavity
The metal outer cavity is manufactured from alloy materials using melting and injection molding technology, thus creating a stable, precise, and esthetically pleasing cavity that is both durable and reliable.

>Equipped with Pring Tips
"Chu" comes standard with the popular Spring Tips eartips.

Spring Tips suppress undesirable resonance through a special diffusion structure, significantly reducing high-frequency linear distortion caused by nozzle resonance, and optimizing natural high-frequency timbre. At the same time, the carefully selected material of the Spring Tips can can better fit the ear canal without stickiness, and the special radial double support stucture can prevent bass loss.

>VDSF
The MOONDROP VDSF Target Response is a parametric target and sound quality is controlled by composite elements, thus restoring the sound quality to mastering levels, and creating an open soundstage with the characteristics of a diffusion-tuned space.
