Striving to become a globally competitive source smart manufacturer of Bluetooth smart digital devices and in-car electronics.
Shenzhen Baiyin Technology Co., Ltd. was established in April 2021 in Bao'an District, Shenzhen, and is located in the Baoyunda Logistics Industrial Park. We are an integrated manufacturer specializing in Bluetooth audio, in-car electronics, and IoT anti-loss hardware, covering R&D and design, mold tooling, production, and both domestic and international sales.
The company focuses on four core business areas: Bluetooth acoustics, in-vehicle power supply, in-vehicle infotainment, and smart positioning. Our main product lines include four series: Bluetooth earphones, car Bluetooth FM transmitters, multi‑protocol fast‑charging car chargers, and Bluetooth smart trackers. We are one of the few comprehensive manufacturers that cover both personal Bluetooth audio consumer products and automotive electronic accessories. With full in‑house production qualifications, we are well‑equipped to undertake OEM/ODM custom development, private mold design, brand labeling, and bulk contract manufacturing.
R&D and Product Capabilities
We have assembled a seasoned R&D team spanning hardware, software, structural engineering, and acoustic tuning, with years of deep expertise in Bluetooth audio algorithms, low‑power transmission, fast‑charging voltage regulation, anti‑interference signal processing, and smart positioning sensing. To date, we have secured multiple design patents and mature solution portfolios for our in‑car Bluetooth and audio products.
Our comprehensive product lines cover a wide range of scenarios:
Bluetooth Earphones Series: Cost‑effective consumer‑grade in‑ear stereo earphones, supporting HD calling, immersive surround sound, low‑latency transmission, and long battery life. They are ideal for daily commuting, sports, entertainment, and business calls.
Car Bluetooth FM Transmitters: Supporting lossless music playback, FM transmission, HD noise‑canceling calls, voltage monitoring, and multi‑mode ambient lighting. They are compatible with all mainstream passenger cars, trucks, and older vehicle models – plug‑and‑play ready.
Car Charger Series: Compatible with QC, PD, and other major fast‑charging protocols, with multiple ports for simultaneous output. Built‑in protection against over‑voltage, over‑current, short circuits, and overheating ensures stable, safe, and rapid charging with strong compatibility.
Bluetooth Smart Trackers: Featuring low‑power consumption, long battery life, two‑way alarm, precise item finding, and anti‑loss alerts. Widely used for keys, backpacks, luggage, wallets, pets, and as safety trackers for seniors and children.
All product lines are continuously upgraded and can be customized in appearance, functions, lighting effects, voice prompts, software interfaces, and other personalized features according to market demands.
Production and Quality Control
Our facility is equipped with standardized assembly lines, SMT workshops, professional audio testing equipment, and aging test racks. We have established a full‑process quality control system covering incoming material inspection, SMT mounting, soldering and assembly, functional testing, whole‑unit aging, and finished‑product inspection.
All products have obtained internationally recognized certifications, including CE, FCC, and RoHS. Our Bluetooth earphones undergo professional acoustic calibration for sound quality, battery life, and call performance. In‑car products are rigorously tested for anti‑interference, voltage stability, high‑temperature resistance, and driving compatibility. All digital accessories meet cross‑border sales standards worldwide, ensuring stable quality and low return rates.
