1. Optimized the structure and volume ofdynamic driver and acoustic cavity through FEA finite element simulationcombined with repeated experimental verification, so as to achieve unparalleledlinear distortion performance.

2. The overall design adopts modernistaesthetic shadow design, showing a three-dimensional and rich layering.

3. Casted by MIM powder metallurgy process,which can achieve high-intensity and irregular appearance.

4. Equipped with a 10mm newly developed ULTsuper linear dynamic driver, both nonlinear distortion and linear distortionare excellent.

5. The third-generation DLC compositediaphragm is designed based on the demonstration and combination of acoustic characteristics. After repeated experiments by FEA finite element method, thenonlinear distortion of the first-generation DLC diaphragm can be reduced by atleast 80% compared with the actual measurement.

6. The acoustic front cavity of KATO isdemonstrated and calculated based on the characteristics of the driver, withhelp of the volume and structure simulated by FEA finite element simulation,and the verification and improvement by repeated experimental, presenting anexcellent frequency response and high-frequency phase performance.

7. It comes with two replaceable nozzle ofdifferent materials, users experience the sound changes for different materialsby replacing the nozzle.

8. Comes with the new-improved 3rdgeneration patented anti-blocking filter, with a newly developed and designedspring eartips and a star-twisted high-purity copper thick silver-plated cable.
