KATO optimised the structure and volume of the ULT dynamic driver and acoustic cavity through FEA finite element simulation combined with repeated experimental verification to achieve unparalleled linear distortion performance. It displays outstanding in both amplitude-frequency response and phase-frequency response, so that timbre and soundstage get better restored. We developed brand-new Spring Tips silicone ear tips for further optimising the timbre of KATO, which not only improve the wearing comfort and prevent sound leakage but also inhibit the weak resonance of the sound outlet of the ear tips, improving the high-frequency linearity and bring a more natural timbre.

We strive to make an ideal sound on KATO, to reflect an unparalleled super cost performance whatever in sound quality, hearing experience and design, to simply continue and sublimate the myth of this series.

THE AESTHETICS OF LIGHT AND SHADOW 

KATO adopts modernist aesthetic design combining light and shadow and continues these design elements from Kanas to KXXS. Thanks to the brand-new MIM technology, On almost all surfaces of KATO have been able to inject light and shadow design, showing a three-dimensional and rich layering.

BRAND-NEW DEVELOPED ULT SUPER-LINEAR DYNAMIC DRIVER

KATO has adopted a new independently-developed 10mm ULT (Ultra-Linear-Technology) super-linear dynamic driver, which has been developed for two years. It includes a more efficient composite magnetic circuit with internal and external magnets and a more linear air circulation structure, as well as a larger brass internal acoustic cavity, a lighter extra-fine imported CCAW sound coil and a high-frequency phase waveguide.

It shows excellent dynamic and abundant details and has amazing performance in both nonlinear distortion and linear distortion through FEA finite element simulation integrated with repeated experimental verification, combining multiple technologies.

THE 3RD GENERATION DLC (DIAMOND-LIKE CARBON) COMPOSITE DIAPHRAGM

The ULT superlinear unit of KATO is also equipped with a self-designed high-performance DLC composite diaphragm, which utilises three materials with different characteristics including DLC to form different parts of the diaphragm. DLC features high rigidity, and a high damping coefficient and is lightweight, as well as its comprehensive acoustic performance even, exceeds that of beryllium.

The brand-new 3rd generation DLC composite diaphragm is designed based on the demonstration combination of acoustic characteristics of materials, and its vibration modality is simulated by FEA finite element and experienced repeated adjustments, its special material application and ratio can enhance the extension details in high-frequency and the dynamic range, build up the system damping and increase the transient details. It can reduce the nonlinear distortion by at least 80% after comparing it with the previous generation DLC composite diaphragm.

CREATE THE DELICATE CAVITY STRUCTURE OF BALANCED TUNING

The acoustic front cavity of KATO is demonstrated and calculated based on the characteristics of the driver, with help of the volume and structure simulated by FEA finite element simulation, and the verification and improvement by repeated experimentation. Combined with the high-frequency phase waveguide components installed on the driver, the front cavity acoustic performance of KATO is far superior to other so-called special tuning components, presenting an excellent frequency response and high-frequency phase performance, which is the hardware guarantee for naturally balanced tuning. 

REPLACEABLE EAR SOUND NOZZLE

Moondrop has designed Kato with a replaceable ear nozzle design. They have included two sets of sound nozzles in the package, made with different materials(Steel & Brass). Both Steel and Brass provide different characteristics to the sound, users can switch between them easily.

SELF-DEVELOPED PATENTED ACOUSTIC FILTER IN NOZZLE

Moondrop Kato has a brand-new third-generation patented anti-blocking filter integrated into the ear nozzle. It prevents oily ear wax from blocking the filters and is more conducive to mid and high-frequency sound.

NEWLY DEVELOPED SPRING SILICONE EAR TIPS

Moondrop has designed new spring silicone ear tips that suppress weak resonance through a special diffusion structure. It also helps in lowering high-frequency linear distortion caused by nozzle resonance making the output more natural and pleasing. These new ear tips also help in providing a better fit for its users.
