Inside Our Earbuds Factory: Assembly, Pairing and Aging Test

Inside our earbuds factory

A short walk through the production line behind our TWS and open-ear earbuds.

At our factory in Longgang, Shenzhen, every model moves through a fixed sequence: incoming material checks, controlled assembly, pairing and function testing, aging and charge-cycle testing, then packing and carton audit.

We build TWS earbuds, open-ear (OWS) models, audio-card + monitoring headset combos and lapel-mic kits for OEM/ODM buyers. CE, RoHS and FCC documentation is prepared for EU and US importers, and customization covers logo, colour, retail box and manual language.

If you are evaluating a new Bluetooth audio line, send your target market, model type, quantity and packaging requirement. We will reply with a sample plan, the QC steps for that model, and a quotation.
