Top China Open Back Headphones Manufacturers & Exporter

Our standard MOQ for custom branding (logo laser etching, custom colorways, and branded packaging) starts at 1,000 units per model. For deep ODM projects requiring completely new acoustic tooling, custom CNC driver grilles, or proprietary PCB redesigns, our baseline MOQ is typically 3,000 units. Trial production runs for established regional distributors can be negotiated upon preliminary technical evaluation.

Yes. Our acoustic engineering department utilizes Audio Precision APx555 sound analyzers and Brüel & Kjær Type 4128C IEC60318-4 head and torso simulators (HATS). B2B clients can provide raw target curves, target EQ profile files, or physical reference benchmark samples. We can calibrate diaphragm damping, back-cavity acoustic foam density, and DSP parameters to meet your exact acoustic signatures.

Every production batch undergoes strict 100% audio testing (THD distortion, frequency response, phase alignment, and channel balance matching within ±0.5dB). In addition, physical reliability tests are conducted in-house: 10,000-cycle headband flex stress testing, drop testing from 1.5m, salt spray corrosion testing for metal grilles, and thermal storage testing (-20°C to 65°C). All components comply with CE, FCC, RoHS, REACH, and California Proposition 65 regulations.

For existing off-the-shelf catalog models with custom laser logo printing, lead times are approximately 15 to 25 calendar days. For full ODM projects: 3D rapid prototyping and acoustic simulation require 10–14 days, steel/aluminum mold creation takes 35–45 days, and golden sample approval leading to mass assembly takes approximately 30 days. We maintain safety stocks of core chipsets and dynamic drivers to expedite urgent reorders.

We uphold strict confidentiality standards for all our international partners. Prior to receiving CAD drawings or product specifications, we execute legally binding Non-Disclosure Agreements (NDAs). Production tooling created for client-funded ODM projects remains exclusive to your brand, backed by segregated cleanroom assembly lines and strict NDA enforcement across our engineering staff.

We provide a comprehensive 18-month factory warranty on all acoustic products. For wholesale distributors, we offer two flexible after-sales options: a standard 1% spare units inclusion with each mass shipment for immediate consumer replacements, or a direct RMA claim process handled through our localized service centers in North America, Europe, and Japan.
