Key Features
Open-Ear Ergonomics: Distributes weight across the anti-helix curve to reduce in-ear pressure buildup during prolonged wear.
Leakage-Suppression Design: Incorporates a reverse-sound-wave chamber structure to direct audio toward the ear canal.
Apple Ecosystem Integration: Built with standard pairing protocols, battery status pop-up synchronization, and low-latency audio sync for iOS and macOS devices.
Dual-Mic ENC Algorithm: Utilizes digital signal processing (DSP) to filter background noise during voice communication.
RF Stability: Maintained transmission range up to 15 meters under standard operating conditions.
Applications
Outdoor Sports & Fitness
Open-fit design permits ambient traffic noise pass-through for runner and cyclist awareness.
All-Day Office Use
Suitable for remote workers requiring audio equipment for continuous video conferencing without ear-canal occlusion.
Retail & Brand Portfolios
Aligns with consumer demand for non-intrusive personal audio alternatives.
Battery & Charging
Cell Chemistry
Grade-A lithium-ion polymer batteries equipped with over-charge, over-discharge, and short-circuit protection ICs.
Power Management
Standby current controlled under 10 uA during warehouse storage.
Cycle Life
Retains >= 80% original capacity after 500 standard charge-discharge cycles.
Safety Screening
100% aged at 45 degree C ambient temperature prior to case assembly.
OEM & ODM Services
Firmware Customization: Custom boot logos, pairing names, touch-control remapping, and EQ profile tuning.
Industrial Design & Tooling: Rapid prototyping and custom plastic injection molding (ABS/PC materials, matte or rubberized UV finishes). Rapid prototyping samples delivered within 7 business days.
SKU Differentiation: Flexible PCB layout modifications to integrate specific sensor modules upon request.
MOQ Structure: Low entry thresholds for trial orders, scaling to high-volume automated production lines.
Manufacturing & Quality Control
Production Facility: 5,000 square meters dust-free SMT and assembly plant operated by 120 skilled technicians.
Core Equipment: Yamaha high-speed SMT placement lines, AOI (Automated Optical Inspection) systems, and Kemo electro-acoustic testing chambers.
QC Milestones:
- Incoming Material Inspection (IQC): 100% testing of raw batteries, chips, and voice coils.
- SMT & PCBA Testing: ICT (In-Circuit Test) and functional board screening.
- Finished Goods Audit (FQA): 4-point acoustic frequency response sweep, Bluetooth RF signal strength calibration, and drop testing (1.2m concrete surface).
- Defect Rate Control: Maintained below 0.25% through statistical process control (SPC).
Packaging & International Shipping
Standard Packaging: Recycled cardboard master carton containing 50 units, individually sealed in dust-proof retail boxes with EVA inner trays.
Carton Dimensions: 480 x 320 x 280 mm (Gross Weight: approximately 11.5 kg per carton).
Logistics Support: Palletized freight preparation, fumigation-free wooden cases, and direct drop-shipping documentation (MSDS, UN38.3 test reports for air and sea freight compliance).
FAQ
Q: What is the standard MOQ for custom color housing and logo printing?
A: The baseline MOQ is 1,000 units per color SKU for laser-etched logos and custom Pantone color matching.
Q: Are these earphones fully compliant with Apple's MFi program?
A: The hardware uses standard Bluetooth profiles and certified chipsets that interface with iOS devices. While not bearing the MFi badge, they achieve functional parity for audio playback, microphone input, and touch controls on Apple devices.
Q: What is the standard lead time for bulk production?
A: Standard production takes 20 to 25 days following sample confirmation and deposit receipt.
Q: Do you provide replacement parts or spare units for warranty support?
A: We supply a 0.3% complimentary pool of spare units alongside bulk shipments to cover immediate after-sales replacement needs.
