NUARL and Audiodo, a Personal Sound System, Form Partnership Partnership Signed


MTI Corporation (Location: Toshima-ku, Tokyo; Representative Director: Keijie Chang) and Audiodo, a Swedish company that provides personal sound technology, have signed a technical cooperation agreement. 

As part of NUARL's approach to playback devices that address the unique hearing characteristics of each individual, last year NUARL introduced Overture, a wired earphone system that allows users to adjust the way they hear sound by changing the sound tube (tonal nozzle) to their personal preference. 

Audiodo's technology is an ideal solution for NUARL's goal of "Sound Personalization" in the field of digital audio, and the two companies have decided to enter into a partnership. NUARL plans to actively develop products that incorporate Audiodo's Personal Sound technology.

As the first product, NUARL has decided to incorporate Audiodo's Personal Sound into the X878 (tentative name), a fully wireless earphone with a hybrid MEMS & dynamic driver and dual DAC bi-amplifier drive, which is currently under development.
