Moondrop Kato Delivers an Evolution of Dynamic Driver Design

MoonDrop Logo
  • Kato takes the aesthetic of light and shadow and applies it to both the visual design and the tuning.
  • The driver design and the acoustic properties of Kato's internal cavity combine to create an incredibly linear, low distortion delivery.
  • Kato's interchangeable nozzles let you experience the different acoustic properties of steel and brass
  • Elevate the experience with a premium accessory package featuring Moodrop's Spring Eartips and star-twisted silver-plated copper cable.

Moondrop Kato IEMs Highlight

Super-Linear ULT Dynamic Driver

KATO adopted a new independently developed 10mm ULT (Ultra-Linear-Technology) super-linear dynamic driver, which has been in development 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 demonstrates 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 Third Generation of DLC Composite Diaphragms

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

The brand-new 3" 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 with the previous generation DLC composite diaphragm.

Interchangeable Nozzle Design

KATO adopts a replaceable sound nozzle design, which can be easily replaced by a quick-release structure with screw thread, and comes with sound nozzles made of two different materials (steel and brass). Users can not only experience the sound changes for different materials by replacing the nozzle, but also replace the blocked sound nozzle more conveniently.

The nozzle of KATO is integrated with a brand-new improved third-generation patented filter, which prevents enhances KATO's ability to filter oily ear-wax that can block the filters, and is more conducive to the middle high frequency sound quality than the previous generation.

A Replaceable Cable  that You Won't Want to Replace

KATO comes standard with a high-purity copper thick silver-plated cable with 4-core star stranded structure, which can effectively reduce the affect of skin effect and proximity effect, and plays an anti-interference role. At the same time, the cable is coated with improved high-permeability mixed materials, which not only has an ultra-low dielectric coefficient, but also has a good looking.

KATO matches a gold-plated 0.78 2pin connector, and the female socket adopts sunken design, which can prevent the pin damage caused by bending to a great extent, and has excellent compatibility. To expand the usage, users can replace the majority of 0.78 2pin cables in the market or Bluetooth neck-hanging module.
