Who We Are
Design, tooling, production and retail-ready packing — one source factory for sleep acoustics.
Shenzhen Hi-FiD Electronics Tech Co., Ltd. is a source factory based in Shenzhen, China, specialising in the design, development and manufacturing of white noise machines and sleep-aid audio devices.
With 17+ years dedicated to sleep acoustics (brand established in 2009), we operate three manufacturing facilities totalling over 6,000 m², 6+ automated production lines, and an annual capacity of 3,000,000+ units.
Visit Us in Shenzhen
Our showroom and production floors are in Shenzhen, and buyers or third-party inspection teams are welcome on site.
Every model currently in production is on display, so a single visit covers the whole range:
- Showroom — every model currently in production, live and on the table.
- Production floors — four assembly lines and two packaging lines.
- Acoustics and reliability laboratory — measured, not estimated.
- Carton and packing review for retail-ready shipment.
Tell us your travel dates and the models you want to see, and we will have them ready when you arrive.
R&D and Engineering
Five disciplines, one building — from first sketch to production firmware.
Over 20 R&D professionals cover the full development chain — exterior ID design, internal structure design, electronic circuits, software and acoustics.
Our engineers and designers work to keep every product functionally sound and aesthetically considered.
Manufacturing and Capacity
Capacity, equipment and inspection — the numbers behind the delivery schedule.
Manufacturing runs on 46+ pieces of production and precision inspection equipment, supported by an in-house reliability and acoustics laboratory.
Incoming materials, in-process units and finished goods are inspected against an internal AQL standard of Critical 0 / Major 0.65.
OEM / ODM Partnership
From logo print to a private mould of your own — three tiers, one agreement.
As a trusted ODM/OEM partner for premium North American and European brands, Hi-FiD has accumulated over 45,000 verified buyer reviews across the sleep-aid models we manufacture.
Customisation is quoted by engagement tier, so scope and minimum quantity line up from the first conversation:
- Light customisation — logo, colour and packaging changes, from 1,000 units.
- Moderate re-moulding — housing and internal structure changes, from 2,000 units.
- Deep ODM — a new platform developed from the drawing board, from 3,000 units.
New models are quoted at the standard tier minimum to protect early market exclusivity for their first buyers.
Light customisation carries a standard lead time of 7 days for samples and 35 days for mass production. For moderate re-moulding and deep ODM projects, the schedule is issued after project evaluation.
All private mould IP is covered by tripartite legal safeguards.
Certifications and Compliance
What we hold in writing — patents, FCC IDs, and the standards we are audited against.
We hold 40+ patents, including an invention patent for Audio Processing Apparatus and Method, and 5 proprietary FCC IDs under grantee code 2AHYH.
Hi-FiD is certified to ISO 9001:2015 and audited by amfori BSCI, with EU unit DoC, CE-EMC, CE-LVD, CE-RED, RoHS 2.0 and REACH compliance, FCC Part 15B, IEC 62471 photobiological safety, and UL- and PSE-certified adapters.
