Dongguan Jolly Industries Limited welcomes a third party to thoroughly inspect our wireless headphones case. The third-party testing is a quality control process where an independent organization reviews our product to see if it meets certain standards. This process is not involved in any other activities, such as design, procurement, fabrication, or installation but the inspection and testing only. We also carry out our own checks in house performed by our experienced and skilled independent QC team. Both processes can lead to a better-quality product.

Jolly specializes in providing professional headphone case solutions for clients. We are engaged in researching, developing, manufacturing and marketing for many years. Jolly is mainly engaged in the business of watch band and other product series. The product works stably under severe conditions.
