Jerry-Chip Apple-Compatible TWS Earbuds

The Jerry-Chip Apple-Compatible TWS Earbuds are white-label wireless stereo earbuds powered by Zhuhai Jieli Bluetooth master control chips (AC69xx/70xx series). Designed for mid-to-high-volume consumer electronics brands, Amazon FBA private-label sellers, and regional import distributors, this platform provides reliable iOS popup-window synchronization, low-latency audio transmission, and stable battery management at a cost-effective price point. Built in an ISO9001-certified facility, the product line supports complete OEM/ODM customization including firmware modification, acoustic tuning, injection molding, and retail packaging.

Hardware-Level iOS Integration: Pre-flashed pairing protocol executes rapid popup-window connection, iCloud device switching, and real-time battery status reporting on Apple operating systems without native app installations.

Jerry AC7003 Low-Latency Transmission: Delivers packet transmission latency down to 45ms for mobile multimedia playback and voice communication.

Acoustic Architecture: Features a 13mm neodymium driver paired with a polyurethane (PU) and titanium-plated composite diaphragm to balance low-frequency response and vocal clarity.

Dual-Mic ENC Algorithm: Beamforming MEMS microphones reduce ambient background noise by up to -25dB during hands-free calls.

Magnetic Hall Sensor: Hall switch enables auto-pairing upon opening the charging case lid, reducing connection time to under 1.5 seconds.

 

 

 

Cell Chemistry: High-density pure cobalt lithium-ion polymer batteries designed to maintain capacity retention over repeated charge cycles.

Circuit Protection: Integrated Seiko protection ICs safeguard against over-charging, over-discharging, short-circuiting, and thermal runaway.

Charging Performance:

• Earbud full charge time: 50 minutes via case contact pins.
• Charging case full charge time: 1.5 hours via DC 5V/1A input.

Transport Safety: Certified for air and ocean freight under UN38.3, MSDS, and 1.2m drop-test transport standards.

 

 

Hardware Customization: Flexible motherboard layout adjustments, alternative Jerry chip configurations, and custom PCB antenna tuning for specific wireless environments.

Firmware Modification: Customized Bluetooth pairing names (editable local device name), custom popup animation graphics, touch control command reassignment, and multi-language voice prompt integration.

Industrial Design & Tooling: Pantone color matching for housing shells (matte, gloss, or rubber-oil finish), laser-etched logos, and customized metal hinge accents.

MOQ & Lead Times:

• OEM (Logo/Packaging print): MOQ 1,000 units, lead time 12 - 15 days.
• ODM (Full tooling/firmware overhaul): MOQ 5,000 units, lead time 30 - 35 days post-sample approval.

 

 

Production Infrastructure: 6 SMT surface-mount lines, 4 automated acoustic testing chambers, and 8 assembly lines yielding a monthly capacity of 600,000 units.

Inline Inspection Protocol:

• Incoming IQC: 100% component-level testing for chipsets, batteries, and diaphragms.
• PCBA Testing: Automated Optical Inspection (AOI) and RF frequency response calibration prior to casing.
• Acoustic QC: Frequency sweep testing to filter out distortion, imbalance, and phase cancellation.

Environmental & Stress Testing:

• Button and hinge fatigue test: 5,000 cycles.
• Salt spray corrosion test: 48 hours for metal contacts.
• Temperature cycling test: -20°C to +60°C.

AQL Standard: Strict adherence to ISO 2859-1 (AQL Major 1.0, Minor 2.5) sampling standards prior to final carton sealing.
