AI-Powered supplier vetting

SummaryThe supplier is identified as a manufacturing factory producing electronic, audio-visual, plastic, circuit-board, digital, and electronic-component products. It reports five production lines, annual microphone output of 2,400,000 pieces, six to ten quality-control staff, three quality-assurance/quality-control inspectors, and 50 years of combined R&D-engineer experience. It offers flexible, minor, and full customization, ODM services, and OEM services for well-known brands. Quality inspection instructions are reportedly available and uniformly followed. However, service-capability procedures, corrective/preventive actions, and complaint-handling procedures lack written records. The supplier has inventory capability and valid manufacturing-capacity contracts with associated subcontractors, but no overseas warehouse or showroom. Financial records are indicated for 2022–2024, but no financial results are provided. Export sales account for 71%–90% of total sales.

Supplier typeThe supplier is identified as a factory in Shenzhen’s Futian District, with associated companies in manufacturing. Its stated business scope covers R&D, production, processing, and sales of electronic, audio-visual, plastic, circuit-board, digital, and electronic-component products. This supports classification as a manufacturing supplier rather than a purely trading or offshore entity.

R&D capabilityThe supplier reports 50 years of combined R&D-engineer experience, new-product development during the past year, ODM capability, and an electronics-related R&D and production scope. However, it does not have an available SDK, so the evidence supports product-development capability but not SDK-based development support.

Production capacityProduction evidence includes factory status, five production lines, annual microphone output of 2,400,000 pieces, inventory capability, and valid manufacturing-capacity contracts with associated subcontractors. The supplier also reports a one-month average lead time in both peak and off-season periods, supporting established production capacity, although no broader product-output figures are provided.

Customization capabilityThe supplier explicitly offers flexible customization, minor customization, and full customization, and also provides ODM services. These stated capabilities indicate support for both limited modifications and more comprehensive product-design or manufacturing customization.

Client casesThe supplier states that it provides OEM services for well-known brands, and export sales represent 71%–90% of total sales. These points indicate experience serving branded and overseas customers, but no specific customer names, project descriptions, or verifiable case details are provided.

Product Q&A

Q:Why is the price higher than others?

Our design uses exclusive private molds with higher costs, avoiding bad competition. We use high-quality imported chip sets to ensure good quality, reduce complaints, and lower after-sales costs, bringing more profits.

Q:Why the lead time is so long?

Normal lead time is 35 days due to high demand. Special requirement orders are excluded. Fast delivery is possible upon negotiation but may incur surcharges.

Q:Do you have Retail Price limit?

Yes, we have a lowest retail price limit to ensure fair competition and reasonable profits for partners, helping ensure the item is good and healthy for long-term sales.

Q:How do you ensure the quality?

We follow ISO9001 system with AQL 0.65/1 standard. We have professional anechoic chambers, frequency response testers, and a reliability lab. Our QC team of over 30 staff handles IQC, PQC, LQC, and FQC.

Q:What is the warranty policy?

Warranty is 1 year for the main unit (excluding accessories) and 6 months for accessories. We are fully responsible for factory-defective products, offering replacements or full refunds.
