Why Aurora Sound Is the Wireless Microphones Manufacturer Global Buyers Trust
Aurora Sound is a Shenzhen-based wireless microphones manufacturer supplying lavalier, handheld and dual-channel systems to content creators, educators and professional audio brands. We run our own SMT lines, acoustic assembly and RF testing in-house, so the wireless microphone you approve as a sample is the same unit that ships at volume.
Our wireless microphone range covers 2.4GHz digital lavalier systems for smartphone and camera use, UHF handheld systems for stage and karaoke, and dual-channel kits for interview and two-person recording. Every model is built for OEM and ODM programs, with logo, colour, packaging and firmware customization available from low minimum order quantities.
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.

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 wireless microphone 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 Wireless Microphones
| 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 |
|---|---|---|
| RF pairing & stability | 2.4GHz / UHF bench test at 20m and 50m | No dropouts within rated range |
| Audio frequency response | Sweep 50Hz-18kHz | Meets published response curve |
| Noise cancelling check | 80dB ambient noise chamber | ENC reduces ambient by rated margin |
| Battery runtime | Continuous playback to cutoff | Meets or exceeds rated hours |
| Drop test | 1.0m, 6 faces, packed and unpacked | Housing and solder joints intact |
| Button & port cycle | 5,000 press / 500 insertion cycles | No mechanical failure |
| Thermal cycling | -10°C to +55°C | Stable operation and battery behaviour |
| AQL sampling | ISO 2859-1 general inspection level II | Lot-level quality gate before dispatch |

FAQ — Wireless Microphones Manufacturer Buyers' Top Questions
What is the difference between a wireless microphone supplier and a wireless microphones manufacturer?
A supplier resells existing catalogue products and typically cannot change firmware, housing or RF tuning. A wireless microphones manufacturer like Aurora Sound owns the SMT lines, acoustic assembly and RF test equipment, so we can adjust the PCB, the microphone capsule, the noise-cancelling algorithm, the housing tooling and the retail packaging. If your program needs a private-label model that does not exist in anyone else's catalogue, you need a manufacturer rather than a trading company.
What is the MOQ for custom wireless microphones?
Stock models ship from 1 piece, which makes sampling and small pilot runs straightforward. Logo printing starts at 5 pieces. Custom colour and packaging start at 100 pieces. Firmware changes such as EQ tuning, custom voice prompts or pairing behaviour start at 500 pieces. Full ODM with new housing tooling typically starts at 1,000 pieces depending on tooling cost.
Do your wireless microphones work with both iPhone and Android?
Yes. Depending on the model we offer USB-C receivers, Lightning receivers and 3.5mm TRS/TRRS receivers, plus 3-in-1 adapters that cover Lightning, USB-C and 3.5mm in a single SKU. K15 ships with a 3-in-1 adapter as standard. We confirm the connector mix with you before tooling so the retail package matches your target channel.
Can you provide FCC and CE certification for the exact model I order?
Yes. Our wireless microphone models carry CE, RoHS, FCC and BQB listing where Bluetooth is used. Because we hold the certification on our own designs rather than borrowing a factory's generic report, the certificate matches the exact model number, housing and RF module you are buying. We provide test reports and certificate copies with the first shipment and on request during the quotation stage.
What wireless platform do you use, 2.4GHz or UHF?
Both, chosen by application. 2.4GHz digital gives compact size and direct smartphone compatibility, which suits lavalier and creator products. UHF gives longer range and better performance in crowded RF environments, which suits stage, karaoke and event use. We will recommend the platform during the engineering review once we know your target range, channel environment and price point.
How long does a wireless microphone OEM program take from inquiry to shipment?
Stock models ship in 3-7 working days. Logo and packaging customization takes 12-18 days. Firmware or acoustic tuning takes 35-45 days including prototype approval. A full ODM program with new tooling runs 60-90 days. Engineering review of your requirements is returned within 1-2 working days of a complete inquiry.
