Audio Cable Samples and Specification Approval
Every custom cable starts with a written specification and a sample you approve. Here's how it works, what it costs and how long it typically takes.
Step 1
A specification in writing, before anything is made
| You provide | We deliver |
|---|---|
| Cable type, use case and target market | Recommended construction and options |
| Quantity range and target timing | A quote by quantity: within 2 business days for standard products, 3–5 business days for custom work |
| Logo files, colors and reference products | A written specification covering conductors, shielding, jacket, connectors, pinout, length and packaging |
| Your pinout or drawing, if you have one | Pinout confirmed in writing before sampling |
Nothing goes to sampling until you approve the specification.

Custom samples
Custom samples carry a sampling fee per design, quoted before sampling and credited in full against a bulk order that meets the MOQ and is placed within 60 days. They typically take 7–15 business days; new tooling takes longer.
Shipping
You pay for shipping, or we send samples on your DHL, FedEx or UPS account. Express delivery to North America and Europe typically takes 3–7 days.
Payment
Samples are paid 100% in advance by bank transfer or PayPal; PayPal fees are added to the invoice. We only accept payment to bank accounts in the name of Haisen Innovations Limited, and we will never change our bank details by email.
Who can request samples
We supply business customers only. Please include your company name and website with your request.
Your approved sample becomes the golden sample
Once you approve a sample, it becomes the golden sample — the reference for production and for the pre-shipment inspection of every bulk order. If you want changes, we update the specification and, where needed, make a revised sample before production.
Typical timing
How long sampling typically takes
| Stage | Typical time |
|---|---|
| First reply to your request | Within 1 business day |
| Stock samples dispatched | 2–5 business days |
| Custom samples | 7–15 business days |
| New tooling | Adds 15–25 days |
| Express delivery to North America or Europe | 3–7 days |
Times are typical and start once the specification and sample fee, if any, are confirmed. Your quote confirms the dates. Production pauses for about 2–4 weeks around Chinese New Year.
