What are raw materials for running earphones production?
2020-11-02
All materials used to manufacture running earphones must meet safety, quality, and legal requirements in the industry. Most of manufacturers have an in-house QC team to assess and test the qualification of their raw materials before they actually apply them to the production of running earphones. Sometimes, they will also entrust the third party to further test and verify their raw materials or ask their raw materials suppliers to present necessary internationally-recognized certificates. The raw materials are the foundation of finished products, thus should be strictly selected.
