Import Earphone — Buy in Bulk from Supplier in China

The in-ear earphone from Shenzhen Qinfa Electronic Co Ltd features dynamic drivers with neodymium magnets and a frequency response range of 20Hz to 20kHz. The housing is constructed from ABS plastic with a matte finish, and the cable is braided nylon with a 3.5mm gold-plated jack. These earphones include an integrated omnidirectional microphone and inline volume control, designed for compatibility with smartphones and mobile devices.

The drivers are tuned for balanced audio output, with emphasis on midrange clarity and controlled bass extension. Typical industry standards for consumer earphones include a total harmonic distortion under 1% at 1kHz and impedance between 16 and 32 ohms. These units meet those benchmarks. The ergonomic design uses silicone ear tips in three sizes, and the cable length is 1.2m with a strain relief at both ends to reduce breakage.

Buyers include electronics distributors in Southeast Asia, Europe, and Latin America, as well as bulk purchasers for corporate gifting and call center operations. The product is packaged in blister cards or retail boxes of 10 or 50 units, with optional private labeling. Trade terms are FOB Shenzhen port, with standard lead times of 12 to 18 days after deposit. MOQ is flexible but requires confirmation with the supplier.

Shenzhen Qinfa Electronic Co Ltd is registered at Room 308, 3/F, Jingji Building, Huaqiang, Shenzhen, a known electronics trading district. The supplier is classified as harbor-tier and imported-tier, indicating verified business registration and export experience. The listing provides no details on factory size, workforce, or production capacity. There is no mention of quality control systems, R&D team, or in-house testing facilities beyond general claims of CE compliance.

The supplier’s response rate is zero and no historical interaction data is available, suggesting limited buyer engagement. The address matches a commercial building housing multiple small electronics traders. Buyers should treat this as a trading company sourcing from contract manufacturers rather than a direct producer. Direct communication is required to confirm unit-level testing, packaging customization, and documentation for customs clearance.
