final "new standard" completely wireless "ZE3000". Exceeds wired E3000

final will launch its own brand on December 17th. It claims to be a "completely wireless earphone that can be said to be a new standard", and the product name is derived from the wired earphone "E3000". The price is an open price, and the expected store price is around 15,800 yen. The colors are BLACK and WHITE.

Since its launch in 2017, the wired E3000 has sold over hundreds of thousands of units in Japan and overseas. “At the time when the E3000 was released, the majority of earphones in the same price range were products that emphasized both the low and high frequencies in order to give a strong impression when listening. On the other hand, the E3000 chose a natural sound creation that does not create an emphasized band based on academic knowledge such as acoustic engineering and psychoacoustics.It is not flashy when you listen to it, but you can focus on enjoying the music. It received high praise mainly on SNS as a product that can be used, and as a result, it became a product that is said to be a standard earphone.”

The new completely wireless product is designed with the theme of "exceeding 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 wireless standards that compress and transmit music signals. There was still a big problem with the

That is the problem of excessive low frequencies due to completely sealing the case to make it waterproof. The TWS requires a battery, electronic circuit board, antenna, etc., to be housed in the housing at a high density. There are no vents outside the enclosure to optimize pressure in the acoustic space.

As a result, the low frequencies become excessive, and it is necessary to emphasize the high frequencies to balance them. As a result, "many completely wireless earphones have a flashy sound that emphasizes both low and high frequencies."

The ZE3000 is equipped with the f-LINK damping mechanism, which optimizes the pressure in the acoustic space inside the housing and enables sound creation equivalent to that of wired earphones without venting to the outside of the housing. newly developed. It is possible to achieve both waterproof performance and appropriate sound creation in the low range.

Also focusing on units. In order to significantly reduce distortion, we reviewed everything from the manufacturing method and developed a newly designed driver unit "f-Core for Wireless" that achieves ultra-low distortion. “It is now possible to clearly distinguish the fine details of each sound that were difficult to hear because they were buried in other sounds. Even the breadth of the space can be felt firmly.”
