Our R&D and sales center is based in Shenzhen, while our large-scale production facility operates in Shaoguan, ensuring efficient capacity and cost control. We operate an ISO 9001-compliant quality system with full inspection checkpoints (IQC, PQC, FQC, OQC). Our advanced equipment includes laser printers, automatic packaging machines, charge-discharge aging equipment, ANC/ENC testers, Bluetooth multifunction testers, RF testers, and comprehensive battery testers.

Third-party lab testing is available upon request, and we assist with CE, FCC, RoHS, BQB, and other international certifications.

Innovation-Driven R&D & Private-Mold Advantages
Our R&D team comprises structural, hardware, firmware tuning, and industrial engineers. With stable annual investment in new technologies and structures, we launch 15 to 20 brand-new, original private-mold TWS/OWS models every year. We actively file patents for appearance and structural innovations, helping our partners differentiate in the market and avoid price wars over generic public molds.
