Know before you buy
The KATO includes both stainless steel and brass nozzles, which allow you to subtly tweak the sound signature. Changing the material alters the acoustic resonance, giving you a choice between different tonal textures to better suit your listening preferences.
Yes, the KATO uses a standard 0.78mm 2-pin connector. This makes it compatible with most aftermarket cables, allowing you to easily swap in balanced cables or different materials if you prefer.
The patented 3rd generation anti-clogging filter is designed to prevent earwax and debris from entering the driver housing. This helps maintain consistent sound quality over time and reduces the need for frequent deep cleaning.
Yes, Moondrop’s proprietary Spring Tips are designed with a specific structure to improve the seal and comfort within the ear canal. They are engineered to minimize high-frequency resonance, which helps provide a cleaner, more natural sound.
With an impedance of 32Ω and high sensitivity, the KATO is relatively easy to drive. While it will work fine with most smartphones or laptops, using a dedicated DAC or amplifier can help you get the most out of its dynamic range and detail.
The Metal Injection Molding (MIM) process creates a high-density, durable unibody shell that is resistant to daily wear. Beyond its premium feel, the rigid construction helps minimize internal vibrations, which contributes to the IEM's low-distortion sound profile.
