Zeronoise technology is engineered to work in perfect combination with earmuƷs. The ultra-thin design of the temples allows maximum sound attenuation.
Zeronoise temples grant absolute comfort and allows to take the glasses on and oƷ without removing the earmuƷs.
Laboratory tests show that, thanks to Zeronoise technology, the combination of earmuƷs and glasses ensure extraordinary sound attenuation.
