Specification
We translate your requirements — use case, target market, look and budget range — into a written specification covering conductors, shielding, jackets, connectors and packaging. You approve it before sampling begins.
About Haisen Audio
We help brands, retailers and installers bring their own audio cables to market — with written specifications, flexible order sizes and one point of contact from spec to shipment.
An audio cable supplier, not a factory
Haisen Innovations Limited is a Hong Kong-based OEM and private-label audio cable supplier. We focus on one thing: audio cables.
We don't own a factory. Production is carried out by our manufacturing partners in Guangdong, China. Haisen turns your requirements into a written specification, has your cables made to that spec, and stays your single point of contact until the goods ship.

Haisen is your contracting supplier. We quote and invoice in the name of Haisen Innovations Limited, receive payment, and are responsible for what we deliver. That model lets us plan smaller first orders around stock components and give you one contact who understands both the product and your market.
Why Haisen exists
Hunter Hu, Founder
Hunter Hu founded Haisen Audio in Hong Kong in 2025, after eight years in Amazon cross-border e-commerce, where he developed audio cable products and ran stores in that category. At Haisen he defines each product's standard build together with our product team, leads the selection of our manufacturing partners and the QC plan they work to, and handles OEM projects directly.

That background shapes how we work. Faults that drive returns and one-star reviews, such as a plug that works loose or a cable shorter than the listing says, should be settled in the spec, and packaging should meet marketplace rules before stock ships. Haisen was set up to close two gaps that brands keep running into: specifications that buyers and factories read differently, and minimum orders set for large volumes that lock emerging brands out.
Our mission: clear specs and small first runs
Our mission is to make custom audio cables accessible to brands of every size — by speaking the buyer's technical language and by making small, well-controlled production runs practical.
What we do
What Haisen is responsible for
Materials
We define each product's standard build: conductor, shielding, connector plating and packaging. Special materials, such as OCC copper, are available on request and confirmed in writing at order.
Quality control
Your approved sample becomes the golden sample. Before shipment, every bulk order is AQL-inspected against it by Haisen staff or a third-party inspector we appoint; you get the report and photos. Your own inspector is welcome too.
Packaging and marketplace readiness
We plan retail packaging, apply the GS1 barcodes you provide, print Amazon FBA labels and mark cartons to your marketplace or retailer requirements.
Compliance documentation
We can arrange RoHS testing, plus CE or FCC where applicable, per project with reports issued for your brand, and print label information you supply, such as EU GPSR details. Your brand or importer remains the responsible party.
Why work with us
Why brands work with Haisen
One contact who speaks cable
Every project starts with how your cable will be used: on stage, in a studio, in a wall or with a phone. Discuss shielding, conductors, connectors and compliance with our product team, and we turn that into a written specification.
Low MOQ, mixed designs welcome
Test a design, a colorway or a new market before you scale. You can combine several designs in one order to reach the minimum. MOQ depends on the cable type, length and level of customization, and we confirm it in your quote.
Retail and e-commerce ready
We plan packaging, barcode and FBA labeling, and cartons so your cables arrive undamaged, scan correctly and look right on the shelf.
Three product families

Hi-Fi & Headphone Cables — IEM and headphone upgrade cables, braided cable core, plugs and connectors for earphone brands and cable builders.
