Moondrop Chu Entry-Level Killer Wired Dynamic IEM

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 adopted a completely different design concept, a more traditional Chinese styling, and significantly upgraded acoustic architecture.

10mm Composite Cavity Dynamic Structure

Adopting the Aria's decentralized dynamic structure, 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 Target Response[1], the acoustic coupling cavity needs to be carefully controlled. Through volume and dimension calculation, FEA finite element simulation and 3D printing experiment verification, an acoustic coupling cavity has been created which can accurately reproduce the ideal frequency response.

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 mixing professionals.

VDSF

The MOONROP 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.

[1] MOONDROP VDSF Target Response is a target frequency response curve based on the HRTF (head related transfer function) of B&K HATS under diffusion and the ideal room preference curve. The closer the frequency response curve measured under B&K HATS is to the target frequency response curve, the more the earphones can reproduce soundstage imaging in terms of frequency response.

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 Spring 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 cap can better fit the ear canal without stickiness, and the special radial double support structure can prevent bass loss.
