A steady source of braided cable core, connectors and finished headphone cables — specified in writing, with no material claim we can't stand behind.
Sound familiar?
Building cables shouldn't mean guessing at materials
“Everyone says OCC; nobody proves it.”
“Hand-braiding capacity limits how many cables you can sell.”
“You need small meterage, not full reels.”
“Connector pinouts differ between brands, and mistakes are expensive.”
How Haisen helps
Materials confirmed in writing, assemblies built to your pinout
Pre-braided cable core
4- and 8-strand round-braided cable core to save hand-braiding time, plus finished cables made to your pinout. 16-strand, flat and square braids are made to order.
Small meterage
Cable core on 5 m and 10 m reels, so you can test a construction before committing to 50 m or 100 m reels. 1 m sample lengths are available for test builds.
Pinouts in writing
Source plugs (2.5 mm, 3.5 mm, 4.4 mm balanced) and headphone-side connectors (MMCX, 0.78 mm 2-Pin), with the pinout confirmed in writing before sampling. All parts are unbranded, with no third-party markings.
Inspected before shipment
Every bulk order is AQL-inspected against the approved sample before it ships — including continuity and pinout on sampled units — and you receive the report and photos.

FAQ for builders
Questions from cable builders
Do you sell OCC or silver-plated copper?
On request. Our standard cable core uses oxygen-free copper (OFC). Tell us the conductor you need, such as silver-plated copper or OCC, and we confirm the material in writing at order. We don't print a material claim on a label unless it is confirmed.
Can I buy braided cable core by the meter?
Not cut to length. Braided cable core comes on 5 m, 10 m, 50 m and 100 m reels, so the smallest order is one 5 m reel. For a test build, ask for a 1 m sample length.
Can you make cables to my pinout?
Yes. Send your pinout or wiring diagram, and we confirm it in writing before sampling. The approved sample becomes the reference for production and inspection.
Can I get samples of cable stock?
Yes. Samples of stock cables are free of sample charges, up to 2 pieces per design and 5 designs per request; you cover shipping or use your courier account.
Do you work with one-person workshops?
Yes, as long as you buy as a business. Please include your business or brand name and website when you contact us.
