<Headphone Festival> final completely wireless "ZE3000" announced / What does the world's first ASMR-only completely wireless sound like?

"Autumn Headphone Festival 2021 ONLINE" was held on September 19th. This time it was an online only event, but as in previous years, many manufacturers introduced and announced new products. In this paper, we report the delivery contents of ag and final. ■ ag "COTSUBU for ASMR" ag introduces the world's first complete wireless earphone dedicated to ASMR "COTSUBU for ASMR" announced the other day. From the final brand, which handles ag, we are developing the ASMR / binaural recording dedicated wired earphone "E500" and its higher model, the binaural audio specialized earphone "VR3000 for Gaming".

"COTSUBU for ASMR" This COTSUBU for ASMR is said to be a model realized by evolving the E500. The E500 has sold more than 200,000 units in total, and it is spreading as "this is the one to listen to the voice of your favorite voice actor", but it will be lined up as the long-awaited completely wireless version. Not only is it wireless, but the sound is also appealing that it has been brushed up from the E500. A representative from the manufacturer explained, "Unless the drivers are properly controlled, sound that provides a natural immersive experience cannot be achieved. It was difficult to achieve this with wireless earphones, and development took a long time." However, by taking the time to develop it, he boasts that he was able to achieve expressive power that "passes between the E500 and the VR3000, such as the sense of distance in the reading voice." Special MC Kotori Koiwai also said, "I listened to ASMR like the sound of water flowing, but the size was completely different. I felt a wide space that I didn't think was attached to my ears, and the band of my breath. It's completely different from normal earphones, so I'd like ASMR creators to use it." Kotori Koiwai is also recommended as an ASMR creator, and the fact that it has become wireless and has no cables was introduced as an element that enhances the sense of immersion. The color used is lavender. In addition to the two-tone charging case, another major feature is that the letters ASMR are printed on the inside of the earphone body. Other functionality is followed from "COTSUBU" such as IPX4 and one ear mode. Although the price has not been announced, "I want to make it affordable". The release date was announced as mid-November. ■final "ZE3000"The final brand, which has "ASMR" printed on the inside of the earphone, announced the completely wireless earphone "ZE3000". So far, final's completely wireless earphones have been released in collaboration with "Evangelion" and "Daisuke Namikawa", but this is the first final brand original completely wireless earphone that is neither a collaboration nor an ag brand. The "ZE3000" product is still under development, so it was announced without the actual product yet, but as a design, by incorporating the surface configuration that was also adopted in the A series, in addition to wearability, touch operation is also possible. Consider making it easy to do. The housing is textured like a high-end camera, enhancing the texture. As a final brand, it is said that functions such as noise canceling have been eliminated from the concept of competing in sound quality even wirelessly. In the development, as a constraint of a completely wireless earphone, it was necessary to mount various parts in a small housing, and it was difficult to achieve sound quality like a wired earphone, and it was difficult to announce it. The driver is equipped with one 6mm dynamic driver newly developed exclusively for wireless. He believes that the most important thing for a wireless earphone driver is accuracy, but since it is assembled using adhesive, there will inevitably be variations in accuracy within a certain range. Final has a policy of acoustic tuning, but wireless products need to use EQ at the end, and this variation adversely affects EQ tuning. Therefore, in this machine, by using silicon that can be heat-sealed on the edge, it was possible to crimp the dome without using adhesive. As a result, it is said that the speed of rise is fast and the sound that clearness is missing one step further is realized. Also, in a completely wireless earphone, the vent cannot be opened due to waterproofing, and this unit also does not open the vent inside, but we adopted a structure in which the front and back of the driver are connected with a 0.8mm tube. I also like the charging case. He made a large number of prototypes and searched for the optimum shape, such as ease of grip and whether it would fit in a pocket. A number of samples of the charging case have been prototyped, and the details of the product pursuing the optimal shape will be officially announced in October and November, and they hope to release it by the end of the year.
