Frequently Asked Questions
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.

These drivers were placed into heavily modified Pioneer SE305 closed back headphones. After 40 hours of use they produce smooth clear highs with no harshness, mids are outstanding-clean and clear, bass is very good-sharp and punchy-not bloated-extends deeply. These are very good drivers for closed back replacements.
John Richmond Santos –
Dropped these 50mm HT50AC drivers into my latest DIY over-ear build and I’m honestly blown away.
Just a heads up: at 320 ohms, you absolutely need a proper desktop amp to wake them up. But once they get enough juice? Pure magic. The PU + Carbon Fiber diaphragm delivers insanely textured, deep bass that doesn’t bleed into the mids at all, and the highs are crisp without getting harsh. The CNC metal housing feels premium and controls resonance perfectly.
If you have the gear to drive them, these are incredible value for any custom project. Absolute monsters!
