Greeting from chairman

On the occasion of the start of CROSSZONE


I have been running Taiwan-based Asia Optical, which is the parent company of CROSSZONE, for 40 years. Asia Optical has long been focusing on manufacturing lenses and optical products and applying techniques thereof to the manufacture of optical devices like digital cinema and laser range finders.


During long-distance travel, I would wear headphones to enjoy music but I became more and more dissatisfied with the discomfort after long-time wearing.


Not until I told my dissatisfaction to a technician from a famous Japanese audio machine manufacturer, which is a long-term partner of Asia Optical, did I know that the biggest flaw of headphones is that the acoustic image is affected by the center localization. (center localization: a phenomenon in which sound concentrates at the center of the head because the two completely separate loudspeakers of the headphones are set by the ears)


From that, I imagined that headphones without such flaw would be groundbreaking. Therefore, I have employed an acoustic technician from a famous Japanese acoustic device manufacturer and incorporated our precision processing technologies. Through 2 years of exploration, we have finally succeeded in developing a kind of headphones that is able to provide unprecedented acoustic image performance.


To deliver the headphones to everyone of you who is dissatisfied, like me, with the old headphones in physical form, we will establish a company and a brand, which are both named CROSSZONE, and release the CZ-1, the first-generation product manufactured in the R&D and production base in our R&D center in Okaya of Nagano that clusters precision machinery manufacturers.


While adopting the new technologies of the CZ-1, CROSSZONE will continue developing brand new and characteristic products. It will definitely grow into a lovable company.


Thank you for your preference for CROSSZONE!


Best regards,



Chairman of CROSSZONE LTD.
