Noise is always a problem in modern chaotic world, and highly affects our daily communications. Before Kulivox was set up, the team was trying to find a better way to share our superior ENC (Environmental Noise Cancellation) experiences. We have been searching for products that would allow us to provide the peaceful environment in voice communication. But in reality, the noise cancellation solution in the market is still a passive one and the noise reduction is usually under 25dB (based on our survey). People have already gotten used to the noise sneaking into our calls. We intend to solve this problem from the root, that is, to isolate the noise from the speaker side so that only the caller’s voice can be delivered. Our technology is to create a virtual silent room anytime anywhere and let people make peaceful moment with each other. When we could not find the right gear to realize this vision, we decided to build it ourselves. We have not stopped building since.
