Sian consistently makes effort on improve factory management and efficiency.
As you may know, we almost have every single model of ear plugs & ear muffs tested to get a certification on SNR & NRR.
In order to earn your trust, we’re applying for more CE EN352-1 & EN352-2 and ANSI certificates for our hearing protection earplugs & earmuffs. CE authority will do a factory audit in a year after product certified to make sure the factory has the capability to manage the quality of products. The capability of stable production. The CE factory audit will be finished this September.
