15,000 earbuds launched after stronger OEM checks
A Cairo distributor needed to rebuild its earbud supply after two failed OEM attempts. LIFA qualified two manufacturers and coordinated a launch order delivered in nine weeks, with dead-on-arrival units reduced from 12% to 0.9%.

- The buyer
- A Cairo, Egypt electronics importer-distributor with 6 retail branches and a B2B client base.
- The product scope
- TWS earbuds; OEM production, Bluetooth 5.3, optional ANC, 2 colorways, custom branding.
What needed to change
Two prior OEM attempts ended in counterfeit Bluetooth chips detected in QC and a 12% dead-on-arrival rate at retail. No qualified OEM list existed, and MOQs of 3,000 units per model were 2.5× the launch demand.
How LIFA managed the work
- Verified 11 OEM factories, including chip-sourcing documentation and production-line visits.
- Ran chip-authenticity checks (serial verification with the chip vendor) on samples.
- Set a 3-stage QC protocol: incoming chip inspection, mid-line checks, and final AQL 1.5 sampling.
- Negotiated MOQ down from 3,000 to 1,200 units and clarified tooling terms.
Recorded results
2 qualified OEMs engaged; DOA rate 0.9% at launch (vs 12% prior); the MOQ reduction freed ~$24,000 in working capital; the launch order of 15,000 units was delivered in 9 weeks.
What this project shows
Component authenticity needed checking before production. The buyer also needed an order quantity that matched launch demand, with QC at three production stages.
