Import Bc300 Bone Conduction Headphone, 8h Playtime — Buy in wholesale FOB from Supplier in China

The BC300 is a sports-oriented bone-conduction headset engineered around a BK3296 Bluetooth 5.2 chipset and a slightly smaller 15 x 12mm transducer pair than its stablemate BC200. It decodes SBC and AAC audio over A2DP, HFP, HSP, AVRCP and AVDTP profiles with the same 10m open-field range, yet extracts a full 8 hours of playback at 60 percent volume from an identical 3.7V/180mAh cell. Frequency coverage remains 20Hz-20kHz, but sensitivity rises to 86 ±3dB with impedance held at 8Ω. The IPX7 waterproof rating, 200-hour Bluetooth-connected standby, and 2-hour recharge cycle are shared with the BC200, though the BC300's 142 x 105 x 42mm footprint and 32g mass suggest a marginally more compact wrap geometry.

Frame construction uses hypothermia-grade titanium alloy combined with PC and silicone, but the BC300 adds ABS plastic housing to the mix rather than relying solely on the titanium band. This material choice can influence resonance damping and long-term hinge fatigue, particularly in temperature-cycling climates. The 15 x 12mm transducer format trades some length for extra width, which may alter contact-pressure distribution on the mastoid process; users with smaller temporal bone protrusions could find the fit more secure. Colours offered are black, white and gunmetal, the latter a finish that demands confirmation of anodising or PVD layer thickness for coastal corrosion resistance. Voice-assistant support covers Siri and Google Assistant, with microphone placement optimised for wind-noise rejection during cycling.

Buyers span fitness-equipment wholesalers, corporate wellness procurement teams, and hearing-aid retailers who need longer battery endurance for all-day wear. The BC300 suits marathon training, warehouse voice-picking, and motorcycle touring where helmet compatibility and sweat protection are equally critical. Because the supplier shows zero response-rate data, distributors should treat quoted availability as indicative only and lock delivery schedules only after direct confirmation from Shenzhen Winto Technology's sales team.

Shenzhen Winto Technology Co., Limited maintains its registered address at 2nd Floor, Building 1, Jinfushun Industrial Park, Lezhujiao, Hangcheng Street, Bao'an District, Shenzhen 518000, Guangdong. The firm's platform profile carries a Harbor trust badge, but the response-rate field reads 0.00 percent and no average response time is logged. This absence of engagement metrics means buyers should not rely on rapid quotation turnaround and should budget extra lead time for initial negotiations.

The supplier produces multiple bone-conduction SKUs, with the BC300 positioned as the longer-playback successor to the BC200. No audited financials, employee figures, production-capacity claims, or named OEM clients appear in the disclosed data. Importers are advised to request a current business licence, any ISO or BSCI documentation, and a factory-inspection report before committing to volume orders, because the profile alone does not establish operational scale or quality-system maturity.
