Specifications

Our Factory

Q: Do you offer OEM/ODM services and custom acoustic tuning?

A: Yes, we provide full OEM and ODM solutions. We offer two types of customization. The first requires a minimum order of just 2 units, selecting from our extensive range of existing materials (like building blocks). The second is a full customization requiring new molds, where the MOQ and delivery time depend on the development difficulty. We can customize coil size, diaphragm materials (such as PEEK, LCP, Titanium, CNTS), and the overall housing design.

Q: What is your Minimum Order Quantity (MOQ) and lead time?

A: For products where we already have the materials in stock, our MOQ is as low as 2 units. For most of our standard models, the MOQ is 100 pieces. Sample orders typically take 3-5 working days, while bulk production lead time is about 10-25 working days.

Q: Are the prices listed on your website for a single unit or a pair?

A: All the prices listed on our website are for a single driver unit, not a pair.

Q: Can I get samples for testing before placing a bulk order?

A: Yes! You can easily purchase samples directly through our official website. Please note that while we do not provide free samples, the sample cost will be fully deducted from your future bulk invoice.

Q: What types of audio drivers do you manufacture?

A: Our product range is diverse, including high-performance dynamic drivers, bone conduction drivers, and planar drivers. They are widely used in HiFi earphones (IEMs), headphones, aviation headsets, and Bluetooth devices.

Q: What are your manufacturing capabilities?

A: We have 19 years of experience in loudspeaker production and research, operating a facility of over 5000 square meters. Combined with China’s mature supply chain and our state-of-the-art CNC precision machining, we offer high-quality products and highly efficient production.
