Sales, technical support, warranty and returns — all the ways to reach us
We serve customers in more than 140 countries and respond to every message we receive. The fastest way to get help depends on what the question is about — pick the channel below that matches your topic and we will be in touch quickly.
General questions, partnership proposals and media enquiries that do not need an instant answer can go to hello@micwlelectronics.com.
Our support team is online Monday through Friday, 09:00 – 18:00 China Standard Time (UTC+8). Emails and contact-form submissions outside these hours are answered on the next business day.
Public holidays in mainland China are observed; we publish an annual holiday calendar at the top of this page so you can plan around it.
For quotes, distributor pricing, bulk orders, OEM/ODM enquiries and product recommendations, email sales@micwlelectronics.com with your region, target product and approximate order quantity.
Most sales messages receive a same-day reply during business hours; complex RF/system designs that need engineering input may take 1–2 business days.
For setup help, firmware updates, frequency coordination, troubleshooting and integration questions, email support@micwlelectronics.com. Please include your order number, the product model, and a short description of the issue.
Critical show-time failures (live performance, broadcast, conference in progress) should also call our on-call line at +86 755 2600 0000 during business hours so we can route you to an engineer immediately.
To open a warranty or defect claim, email warranty@micwlelectronics.com with the order number, a description of the fault, and photos or a short video showing the symptom.
We will issue an RMA (Return Merchandise Authorisation) number and the return address within one business day. See the Warranty & Returns page for full terms.
For 30-day return requests, exchange requests and refund status checks, email returns@micwlelectronics.com with your order number.
Please do not ship anything back before you have an RMA number — unmarked packages can sit in the warehouse queue for several days.
Trade press, podcast producers and reviewers: email press@micwlelectronics.com for review units, interview requests and product imagery.
Distributors, system integrators and channel partners: email partners@micwlelectronics.com. Job seekers: see open positions on our Careers page or write to careers@micwlelectronics.com.
