final Inc. (Representative: Mitsuru Hosoo, Headquarters: Kawasaki City, Kanagawa Prefecture), a Japanese audio manufacturer, will exhibit at "Potafes 2026 Summer Akihabara" (organized by e☆イヤホン), to be held on July 11 (Sat.) and 12 (Sun.), 2026, at Belle Salle Akihabara and Akihabara Convention Hall.

This year's event will be held at two venues, but the final booth will be located at Belle Salle Akihabara 2F-21. The highlights include the world premiere of the new prototype "A8000 DC," a reinterpretation of the design philosophy of the flagship wired earphones "A8000," and the Japan premiere of "Project M2," a new model from DITA Audio, for which final serves as the general distributor in Japan.

Please visit the final booth.

◎final "A8000 DC" Prototype *World Premiere*

The name DC is derived from the musical term "Da Capo," meaning "return to the beginning of the score." Rebuilding the design philosophy of the flagship wired earphones "A8000," which were regrettably discontinued due to material constraints seven years after their release, we have developed a new model with a magnesium diaphragm.

You can experience the A8000 DC prototype, currently under development, at the venue. Please come and try them out.

◎final Closed-Back Headphones "DX10000 CL" with True Diamond Diaphragm

Featuring a true diamond diaphragm manufactured using the CVD (Chemical Vapor Deposition) method, which crystallizes diamond on silicon, we have achieved low distortion rates through a unique dome shape, newly developed edge, and an airborne wiring structure with a voice coil and bobbin.

The housing, precision-milled from aluminum-magnesium alloy using 5-axis CNC, achieves both high rigidity and airtightness through a unique structure that fastens it with 12 screws without any adhesives. This non-adhesive structure allows for disassembly and reassembly, contributing to repairability for long-term use.

The cable is a silver-coated cable co-developed with Jun-Sen, which has a track record of developing cables for the supercomputer "K."

At the Potafes venue this time, you can enjoy listening with a desktop amplifier system.

◎final Flagship Wireless Earphones "TONALITE"

TONALITE is equipped with the world's first (※1) personalization technology "DTAS" for applying tonal characteristics to individuals. By scanning body shapes such as the head, ears, and shoulders with a smartphone camera, it generates and applies a tonal profile tailored to the individual's physical characteristics.

At the venue, you can set up DTAS in as little as 10 minutes and experience the effects of DTAS firsthand.

You can complete the setup and listening experience using only your own smartphone, so please take this opportunity to try the latest acoustic experience.

(※1) As of October 31, 2025, according to our research. A survey was conducted on TWS products from major domestic and international brands with the primary purpose of "applying tonal characteristics to individuals."

◎final True Wireless Earphones for Nighttime Use "ZE500 NYUMIN"

"ZE500 NYUMIN" are earphones developed with a new approach: "to refine, not reject, nighttime smartphone habits."

This new model, currently available for pre-order on the crowdfunding site "Makuake," can be tried out early at the Potafes venue.

At the venue, you can not only try them on and listen to them with the actual product but also experience the actual usage feel before sleep using a real pillow.

Please check the project page below for details on crowdfunding pre-orders on Makuake.
