The product name of ZE3000 is derived from the wired earphone “E3000” that represents the final brand. Since its launch in 2017, the E3000 has sold hundreds of thousands of units in Japan and overseas, and has won the gold medal for the 10th consecutive term, which is unusual for Japan’s largest audio award VGP. At the time the E3000 was released, earphones in the same price range were mainly products with flashy sounds that emphasized both low and high frequencies so that they would give a strong impression when you listen to them. On the other hand, the E3000 has selected natural sound creation that does not create an emphasized band, based on academic knowledge such as acoustic engineering and psychoacoustics. Although it is not flashy when you listen to it, it has received high praise mainly from SNS as a product that allows you to concentrate on enjoying music, and as a result, it has become a product called a standard earphone. When we started designing completely wireless earphones, we wanted to create a product that exceeds the sound quality of the E3000. On the other hand, I also thought that it would be difficult to achieve the same sound quality as wired earphones with completely wireless earphones due to the restrictions of the wireless standard of compressing and transmitting music signals. However, there remained a bigger problem than that.

Although it took a long time to develop, we have completed a product that we can confidently recommend as a new standard for completely wireless earphones.
