We are an audio-first ODM manufacturer based in Bao'an Xixiang, the undisputed global capital of electro-acoustic engineering.
EMS-AUDIO was founded by a team of audio engineers who spent years designing products for the brands you know. We saw an industry where great ideas died in the gap between concept and factory floor — so we built a company to close that gap.
Headquartered in Bao'an Xixiang, Shenzhen — known locally as the "TWS Capital of the World" (TWS耳机之都) — we sit at the center of the world's densest concentration of electro-acoustic supply chains. Within a 5km radius of our office are driver factories, PCB fabs, battery suppliers, mold shops, and packaging vendors. This proximity is our structural advantage.
Every project is led by a senior acoustic engineer who owns the sound signature from first prototype to final production. We measure everything. We listen to everything. We do not ship a product that we would not put our own name on.
Over twelve years, we have shipped 500+ SKUs to brands in 30+ countries — from Amazon-native earbud startups to established European audio houses. Our work has won Red Dot and iF design awards for our clients, and we have maintained a sub-1% field return rate across all product categories.
Why the world's audio brands come to this one district in Shenzhen.
Bao'an Xixiang is colloquially called the "TWS Capital" — an industrial ecosystem that produces the majority of the world's wireless earbuds, Bluetooth speakers, and consumer audio electronics. The supply chain density here is unmatched anywhere on earth.
Our facility is minutes from Shenzhen Bao'an International Airport (SZX), making factory visits and sample handovers frictionless for international clients.
