01 PROFILE
A company that builds solutions
Solution R&D, sample validation, SMT production and delivery — all four under our own roof.
, Ltd is a high-tech company integrating the R&D and manufacturing of technology solutions.
Its main products cover mid-to-high-end TYPE-C audio solutions, gaming headset solutions, TYPE-C digital audio, TYPE-C chargers, TYPE-C fast charging, TYPE-C headsets, TYPE-C speakers, AI noise-cancelling headsets and SMT production line solutions.
Custom development and production are available to meet specific customer requirements.
The company has independent R&D capability: chip selection, audio algorithms, firmware and hardware adaptation are all carried out by an in-house team.
Founded in 2019, the company operates a 2,000 m² production base with three fully automated SMT production lines, covering the full process from solution design and firmware to SMT assembly in-house, and is equipped with a wide range of advanced automation and inspection equipment �.
� the factory is essentially fully automated.
With years of deep experience in the digital products sector, Dongguan Hairunwei relies on technology, values quality and pursues relentless innovation: surviving on quality, growing through credibility and creating value through service.
The goal is to become a first-tier audio solution supplier in China.
02 PROCESS
Six closed-loop steps, requirement to shipment
Selection, hardware, firmware, prototyping, pilot run and volume — all completed in-house. No critical step is outsourced.

03 CULTURE
Four rules we actually hold ourselves to
Not slogans — the criteria we use when choosing suppliers, taking orders and handling exceptions.
Quality is survival
Every batch is sampled and measured. If a spec does not meet the datasheet, it does not ship.
Integrity drives growth
Lead times and costs are quoted realistically, and we report problems before the customer finds them.
Service creates value
From chip selection to firmware tuning and pilot runs, we stay involved until the customer is in production.
