Moondrop CHU High Performance Dynamic Driver IEMs in-Ear Earphone

• Nano-Crystal Coating Composite Diaphragm
• 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 Calculatioof Acoustic Coupling Cavity： In order to match the frequency response as closely as possible to the VDSF Target Response, 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.
• 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.

Accurate Calculation of Acoustic Coupling Cavity

In order to match the frequency response as closely as possible to the VDSF Target Response, 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. This outstanding frequency response curve gives Chu the ability to faithfully reproduce the sound heard by the sound engineer when making recordlings. 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.
