Why Aurora Sound Is the Audio Accessories Manufacturer Global Buyers Trust
Aurora Sound manufactures the accessories that complete an audio product line: braided USB-C charging cables, lavalier microphone windscreens, hard EVA carrying cases, 3.5mm to USB-C and Lightning audio adapters, and silicone replacement ear tips.
Most buyers source these separately and lose weeks reconciling colour, packaging and lead times across vendors. We build them alongside our microphones, glasses, earphones and speakers, which means accessories can ship matched to your product colour and in the same carton.
Short version: we are the factory, not a trading desk. Our production base is operated together with parent company Shenzhen Aurora Technology Limited — 400+ employees, 8 production lines, 5,000,000+ units annual group capacity and a defect rate below 1.5%. Quotation requests are answered within 3 hours. Below is how that compares with a typical catalogue supplier.

|---|---|---|
| Categories | Cables, windscreens, cases, adapters, ear tips | One accessory type |
| Colour matching | Matched to your paired product | Stock black only |

| Bundling | Ships in the same carton as the main product | Separate shipment and lead time |
| Packaging | Retail box or bulk, matched to main SKU | Polybag only |
| MOQ | Bundled with main product order | High standalone MOQ |
| Lead time | Matches main product schedule | Separate 30-45 day cycle |
| Quality gate | Same 5-stage QC as main products | Unverified |
| Certifications | CE, RoHS | None |
Who We Are — Shenzhen Aurora Sound Technology Limited
Shenzhen Aurora Sound Technology Limited is a professional audio acoustic product manufacturer based in Shenzhen. The company is invested by Shenzhen Aurora Technology Limited, an established industrial enterprise with 400+ employees, RMB 300 million annual industrial output, and long-term supply relationships with Walmart, Bosch and Ford.
We specialise in the R&D, production and global export of audio accessory and the wider acoustic range covering lavalier microphones, smart audio glasses, wireless earphones, Bluetooth speakers and voice amplifiers. We currently export to 50+ countries and support FBA and direct-to-warehouse shipment for e-commerce buyers.
Factory Capability — Our Parent-Backed Manufacturing Base
Production Scale
- 8 production lines — SMT, acoustic assembly, final assembly and packing under one roof
- 5,000,000+ units annual group capacity — annual capacity across all audio categories
- defect rate below 1.5% — defect rate held below this on shipped lots
- 100% on-time dispatch — on-time dispatch record
Engineering & R&D
Our engineering team handles acoustic design, RF tuning, firmware and industrial design in-house. That is what allows us to change an EQ profile, a noise-cancelling behaviour or a housing colour within a running program instead of handing the change to a third party.
Vertical Integration
We control driver selection, chamber design, PCBA, firmware and final assembly. For audio accessory programs this means the sample you approve is the unit that ships at volume — the most common failure point when a brand works through a trading company instead of a manufacturer.

Manufacturing Process — How We Build Audio Accessories
| Step | What Happens |
|---|---|
| 1. Incoming QC (IQC) | Components, cells and acoustic drivers inspected against AQL before they reach the line. |
| 2. SMT & PCBA | Automated surface-mount placement and reflow for the main board, followed by AOI inspection. |
| 3. Acoustic assembly | Driver mounting, chamber sealing and acoustic mesh placement in a dust-controlled area. |
| 4. Firmware loading | Bluetooth pairing logic, EQ profile and voice-prompt language written and verified. |
| 5. In-process QC (IPQC) | Sampling at each station; deviations trigger line stop and root-cause review. |
| 6. Final assembly | Housing, battery, antenna and finishing parts assembled; cosmetic inspection. |
| 7. Functional test (FQC) | 100% audio, RF, battery and button test before packing. |
| 8. Outgoing QC (OQC) | AQL sampling on finished cartons plus drop-test verification before dispatch. |
Testing & Quality — Proving Every Unit Before It Ships
We run 5-stage QC (IQC / IPQC / FQC / OQC / AQL sampling). Every unit passes functional test before packing, and finished lots pass AQL sampling before dispatch.
| Test | Standard / Method | What It Proves |
|---|---|---|
| Cable bend & pull | 5,000 bend cycles and pull test | No conductor break or jacket split |
| Connector insertion | 500 insertion/removal cycles | Stable contact, no loosening |
| Case crush | Static load on hard EVA shell | Shell recovers, contents protected |
| Adapter audio | Signal path and DAC output check | No audible noise or channel loss |
| Windscreen fit | Fit check on each compatible model | Secure fit without muffling |
| Ear tip retention | Pull test on stem and housing | Tip stays seated during normal removal |
| Colour matching | Visual comparison under standard light | Matches paired product within tolerance |
| AQL sampling | ISO 2859-1 level II | Lot-level gate before dispatch |
Certifications — The Paperwork That Protects Your Brand
| Certification | What It Means | Why Buyers Need It |
|---|---|---|
| CE | EU conformity for safety, health and environmental protection | Required to sell audio electronics in the European Economic Area |
| RoHS | Restriction of hazardous substances in electrical components | Mandatory for EU and increasingly for US retail channels |
| FCC | US Federal Communications Commission radio-frequency compliance | Legally required for any wireless product sold in the United States |
| BQB | Bluetooth Qualification Body listing for Bluetooth-enabled designs | Lets you legally use the Bluetooth wordmark and logo on retail packaging |

FAQ — Audio Accessories Manufacturer Buyers' Top Questions
Why source audio accessories from the same manufacturer as the main product?
Colour mismatch, fit problems and split lead times are the three most common accessory complaints. When the accessory and the main product come from one manufacturer, the colour is matched under the same lighting standard, the fit is verified against the actual product rather than a drawing, and both ship in the same carton on the same schedule. It removes a coordination step that usually costs more than the accessory itself.
What is the MOQ for custom audio accessories?
Accessories are most economical when bundled with a main product order, in which case they follow the main product's MOQ. Standalone accessory orders start at 100 pieces for stock items and 500 pieces for custom colour, length or packaging. Custom EVA case interiors require tooling and start at 1,000 pieces depending on complexity.
Will your microphone windscreens fit our existing lavalier models?
Our standard windscreens are built to fit ASKS20, J13, Q8, K15 and Mini8, and we verify fit on each of those models. For a lavalier microphone we did not manufacture, send us a sample or the dimensional drawing and we will confirm fit during the engineering review rather than shipping a generic cover that falls off in the field.
Can accessories be packed inside the main product retail box?
Yes. We routinely pack cables, windscreens, ear tips and cases inside the main product's retail box, or as a separate accessory compartment in the same carton. This is specified at the quotation stage because it affects both the packaging design and the packing line instructions.
Do your audio adapters work with both iPhone and Android?
Yes. Our adapters cover 3.5mm to USB-C and 3.5mm to Lightning with a built-in DAC, so they work across iPhone and Android devices. We confirm the connector mix you need for your target market before production so the retail pack matches the channel.
What certifications do your audio accessories carry?
CE and RoHS. Adapters and cables that carry active electronics follow the same compliance path as our main products. Certificate copies and test reports are provided with the first shipment and on request during quotation.
