Explore our flagship OEM/ODM personal audio lineup, acoustic hardware, and precision protective cases engineered for high-performance global distribution.
Navigating the modern consumer acoustic accessory ecosystem requires deep polymer expertise, precision structural engineering, and seamless supply chain integration. As a leading manufacturer in China, we deliver high-gain value for international brands and distributors.
We utilize Liquid Silicone Rubber (LSR), shock-resistant Thermoplastic Polyurethane (TPU), and optical-grade Polycarbonate (PC) to build drop-proof, anti-yellowing earphone cases engineered for extreme physical durability.
Our proprietary high-speed CNC tooling yields micro-grooves and custom magnet cavities with ±0.01mm tolerance, guaranteeing zero signal distortion, flawless wireless charging passthrough, and precise LED illumination windows.
Operating under strict ISO9001 and ISO14001 guidelines, our manufacturing processes comply with international environmental standard regulations including REACH, RoHS, PSTI, and Post-Consumer Recycled plastics (PCR) compliance.
Modern True Wireless Stereo (TWS) earphone cases are no longer mere protective shells; they are complex technical enclosures combining acoustic protection, thermal dissipation, magnetic latching systems, and ergonomic touch feel.
Our OEM/ODM manufacturing capability in China specializes in multi-material co-molding, integrating soft tactile bumpers with rigid structural skeletons to absorb up to 99.4% of impact forces during drop tests.
We engineer protective cases for global audio brands according to stringent physical criteria:
As consumer demand shifts toward sustainable electronics, smart diagnostics, and lifestyle customization, procurement teams must align with suppliers capable of next-gen innovation.
Global retailers are increasingly mandating GRS-certified PCR plastics (Post-Consumer Recycled) and Ocean-Bound Plastics (OBP). Our factory integrates up to 85% recycled resins into earphone protective cases without compromising tensile strength or structural longevity.
The next wave of TWS charging cases incorporates embedded OLED touchscreens, real-time battery status gauges, and Bluetooth location tracking tags (Find My integration). We provide full turnkey ODM tooling for smart electronic case assemblies.
Consumers expect seamless switching between sports carabiners, neck lanyards, and magnetic vehicle docks. Modern earphone case manufacturing relies on integrated stainless-steel pin joints and neodymium magnetic arrays for multi-scenario utility.
How advanced tooling, automated SMT housing assembly, and high-frequency welding are redefining international sourcing expectations.
Precision cold-runner LSR injection guarantees velvety soft-touch surfaces, zero mold flash, and seamless dustproof seals.
Fusing multi-layer graphics beneath scratch-resistant polymer layers prevents print degradation under heavy friction and sweat exposure.
Eliminating toxic glues through high-frequency acoustic friction bonding, creating hermetically sealed waterproof battery chambers.
High-speed industrial cameras screen 100% of finished earphone cases for micro-defects, color variance, and hinge alignment.
Use this strategic engineering matrix to choose the optimal material structure and mold configuration for your target brand positioning.

From initial 3D CAD rapid prototyping in Carlsbad-inspired acoustic labs to mass automated production in China, we provide an end-to-end B2B supply chain advantage.
We control raw resin synthesis, SMT circuit board housing assembly, silicone vulcanization, tool mold design, and final automated packaging under one roof—drastically reducing lead times and middleman markups.
Every production batch undergoes 100% optical inspection, salt-spray anti-corrosion tests, thermal shock testing (-40°C to +85°C), and 10,000-cycle hinge latch wear endurance tests before export release.
We provide complete compliance documentation for seamless import into North America, Europe, the UK, Australia, and Asia, including CE, FCC, RoHS, REACH, PSTI, and California Prop 65 certification packages.
Detailed technical and commercial answers designed for international procurement managers, brand managers, and audio accessory distributors.
We offer end-to-end OEM and ODM customization services for earphone cases and protective enclosures. Our services include initial 3D industrial design rendering, rapid SLA resin prototyping (24-48 hours), custom precision CNC steel mold fabrication (15-20 days), custom Pantone color matching, logo printing (silk-screen, UV print, laser etching, and IMD), and custom eco-friendly retail packaging design.
For standard earphone cases in existing mold configurations, our MOQ starts at 500 units per colorway. For fully customized OEM tooling or specialized PCR recycled polymers, the standard MOQ is typically 1,000 to 2,000 units. Sample lead time is 3 to 5 business days, while mass production orders ship within 15 to 25 calendar days after sample approval.
Our protective cases are engineered using non-magnetic, low-dielectric polymer compounds (TPU, LSR, PC). We calibrate shell thickness (optimal range 1.2mm to 1.8mm) to ensure 98.7%+ energy efficiency during Qi and Qi2 wireless charging. Furthermore, our designs undergo RF signal attenuation testing to guarantee zero disruption to Bluetooth 5.4, LE Audio, or Ultra-Wideband (UWB) tracking signals.
Yes. We provide Global Recycled Standard (GRS) certified Post-Consumer Recycled (PCR) plastics containing between 30% and 85% recycled polycarbonate/TPU content. We supply complete transaction certificates (TC) and material safety datasheets (MSDS) required for European ESG regulations, UK Plastic Packaging Tax compliance, and US sustainability mandates.
Our manufacturing facility in China holds ISO 9001:2015 Quality Management and ISO 14001 Environmental Management certifications. We routinely pass social compliance audits, including BSCI and SMETA (SEDEX). All produced earphone cases comply with CE, FCC, RoHS, REACH, PSTI, and California Prop 65 safety regulations.
We support all standard global trade Incoterms, including EXW, FOB (Shenzhen / Guangzhou / Hong Kong), CIF, DDP (Delivered Duty Paid), and DAP. Our logistics team handles customs clearance, battery/accessory export documentation, and direct delivery to Amazon FBA fulfillment centers or regional retail distribution warehouses across Europe, North America, and Asia-Pacific.
