Our factory has a fully equipped laboratory. Thus, we can test our headphones for sound quality and sturdiness at each stage of the manufacturing cycle. With the use of ‘Control Plan’ management method and under the ISO-9001:2015 system, the entire manufacturing process (sourcing -> purchasing ->goods-in/goods-out -> WIP -> shipment) is closely monitored to ensure the reliability and stability of each single piece of products.
