Sourcing TWS Earbuds & Bluetooth Audio from China
1 resources tagged with "Tws"
TWS (true wireless stereo) earbuds and Bluetooth speakers are among China's most competitive electronics categories, with Shenzhen factories building on chipsets from Airoha, BES, and Qualcomm. Sourcing them well means a factory audit, multi-stage inspection, and getting FCC and CE radio certification right — plus UN 38.3 for the LiPo cells. A disciplined three-stage inspection on a 5,000-unit run can hold the defect rate well under 1%, where untested sourcing routinely lands at several percent.
When you source TWS or Bluetooth audio the failure modes are pairing/connection defects and battery quality, both of which only surface at scale. We run during-production and pre-shipment inspection on pairing, audio, and charge cycles, and confirm the Bluetooth module and battery carry their own certifications.

FAQ
What certifications do Bluetooth audio products need?
FCC for the US and CE/RED for the EU on the radio, plus Bluetooth SIG qualification for the logo, and UN 38.3 for the lithium cells before air freight. Verify each separately rather than trusting one combined claim.
What defect rate is realistic for a TWS or speaker order?
With a factory audit and three-stage inspection, a defect rate under roughly 0.5% is achievable on a few-thousand-unit run. Without inspection, audio and pairing defects commonly run several percent, eating directly into margin.
