Frequently Asked Questions

Q1: What is the minimum order quantity (MOQ) for custom ANC earbuds?
A: MOQ typically depends on the level of customization. For basic branding (logo printing, custom packaging) on an existing ANC platform, MOQ can start around 500–1,000 units. For deeper customization — custom mold, tuned ANC profile, or a unique chipset configuration — MOQ usually rises to 2,000–5,000 units to justify tooling and calibration costs.

Q2: Can you customize the ANC noise reduction level or tuning profile?
A: Yes. ANC tuning (feedforward/feedback mic calibration, noise reduction depth, wind noise handling) can be adjusted within the chipset platform’s capability. This usually requires a tuning sample round — expect 1–2 rounds of acoustic tuning before mass production, which adds 1–3 weeks to the timeline.

Q3: What certifications do the earbuds carry, and can you help with region-specific certification?
A: Standard earbuds typically ship with FCC, CE and RoHS certifications. For specific markets, we can support UKCA (UK) or RCM (Australia) certification on request, though this adds cost and lead time — usually 3–6 weeks depending on the target market’s testing requirements.

Q4: What’s the typical lead time from sample confirmation to mass production delivery?
A: After sample approval, standard mass production lead time runs 25–35 days for orders under 5,000 units, depending on chipset lead time and packaging complexity. Custom mold or packaging can extend this by 2–4 weeks for initial tooling.

Q5: Do you offer private label or white-label packaging?
A: Yes, both options are available. White-label allows using our standard packaging with your brand printed on it (lower cost, faster turnaround). Private label involves fully custom box design, inserts, and sometimes custom charging case shells — this requires design files and typically 1–2 rounds of packaging proofing.

Q6: What’s the battery life and charging case capacity for ANC models, and can it be adjusted?
A: Typical ANC earbuds run 4–6 hours per charge with ANC on (6–8 hours with ANC off), with the charging case adding 3–4 additional charges. Battery capacity can sometimes be adjusted (larger cell for extended playtime), but this affects earbud size and case dimensions, so it needs to be confirmed early in the sourcing process.

Q7: What quality control process do you follow before shipment?
A: Standard QC includes IQC (incoming material inspection), in-process DUPRO checks during assembly, and a final AQL-based inspection (commonly AQL 2.5) before shipment. For ANC-specific units, we also run acoustic function testing on a sample batch to verify noise cancellation performance meets the agreed spec.
