Frequently Asked Questions
Q1: Is this 40mm headphone driver good for over-ear HiFi headphones?
A: Yes. With 107±3dB sensitivity and 32Ω impedance, smartphones can drive it directly to a satisfying SPL with full detail. F0~20kHz full-band response supports balanced tuning for music, podcast, and gaming use cases.
Q2: What is the MOQ and lead time?
A: Standard SKUs start at MOQ 3000 pcs. Trial orders of 500 pcs are accepted for early-stage validation. Customization (spec / housing / packaging) starts at 10000 pcs. Lead time is 3-5 days for stock, 15-20 days for custom builds.
Q3: Can you customize 16Ω, 24Ω, or 64Ω impedance versions?
A: Yes. XDEC carries a full E-class headphone driver lineup with common impedances of 16Ω / 24Ω / 32Ω / 64Ω / 150Ω available. Sensitivity can also be tuned to your enclosure and target SPL - 10000 pcs MOQ for full custom.
Q4: Is this driver suitable for gaming headsets or esports headphones?
A: Absolutely. 107dB high sensitivity helps gamers pick up subtle in-game audio cues (footsteps, gunshots), and 32Ω impedance matches well with PS5, Xbox, Switch, and PC sources. For signature tuning (e.g. bass-boosted), our engineering team can advise on damping and enclosure options.
Q5: Can you provide datasheet, test reports, and samples?
A: Yes - datasheet, dimension drawing, frequency response curve, and reliability test report (load / high-temp / low-temp / humidity) are all available on request. Email xd12@xdec.cn for samples (24h reply) or call our sales director +86 13620938545.
