Engineered for high acoustic clarity, long commutes on JR commuter trains, and serene home-office environments across Tokyo, Osaka, and Nagoya.
Navigating strict Radio Law guidelines, premium acoustic fidelity expectations, and specialized urban use cases.
Japan boasts one of the most sophisticated rail infrastructures worldwide. High-density train travel demands noise-cancelling headphones that attenuate low-frequency rumble (sub-500Hz) while keeping voice announcements clear via ambient sound modes.
Electronic and RF audio gear entering Japan must strictly comply with the Radio Law (Giteki mark / TELEC) and PSE safety standards for lithium batteries. Our automated SMT lines and testing stations ensure pristine regulatory readiness.
With remote work (Zaitaku Kinmu) solidified across Japanese enterprises, dual-microphone Environmental Noise Cancellation (ENC) is vital. Microphones must isolate human speech in micro-apartments and public quiet-zones seamlessly.
Headphone OEM & ODM Expert Since 2006
Shenzhen Sonun Technology Co., LTD., a headphone factory founded in 2006, has carved out a niche for itself in the global market with its exceptional OEM and ODM private-label services. Over the past two decades, we've honed our craft, earning a solid reputation for delivering high-quality, innovative headphone solutions to international brands, with a strong focus on serving leading electronics distributors, lifestyle labels, and e-commerce leaders across Japan.
Our engineering laboratory incorporates anechoic chambers, artificial ear testers (B&K, SoundCheck), and multi-stage RF signal analyzers to ensure every batch aligns with Japanese consumer expectations for zero-defect acoustics and ergonomic precision.
End-to-end bespoke product lifecycles tailored to stringent Japanese industrial criteria.
ODM work has made remarkable progress, mainly due to the input of independent design and research teams in various aspects. The design and research teams create new directions by thinking creatively and moving away from simply following market trends. The ODM team leads the industry trends and delivers product solutions with competitive advantages in the market. Product design combines beauty, comfort and smart technology. Sound quality is at the core of product development, and the research team has repeatedly improved and optimized product performance, committed to providing users with a high-quality listening experience.
For our Japanese partners, our ODM portfolio features minimalist industrial design aesthetics, ultra-lightweight protein memory foam headbands, and energy-conserving chipsets yielding up to 70 hours of hybrid playback time.
Our journey began with a simple yet ambitious goal: to become a leader in the headphone manufacturing industry. Today, we stand as a testament to that vision. Our OEM services are the backbone of our operations. We take great pride in our ability to meticulously follow client specifications, ensuring that each product we produce is a precise reflection of our clients' vision. Our experienced team, armed with state-of-the-art equipment, navigates the production process with precision and efficiency, adhering to stringent quality standards that are recognized globally.
We handle everything from customized laser engraving, bilingual Japanese-English packaging, bespoke EQ curve tuning, to custom firmware flashing that integrates prompt tones recorded in natural Japanese.
Transparent cost modeling, volume scaling, and customization parameters for Japanese buyers.
When calculating quotations for the Japanese territory, Sonun optimizes FOB Shenzhen, CIF Tokyo/Yokohama, or DDP air-freight pipelines. Factors that determine project pricing include ANC chipset architecture (Feedforward, Feedback, or Hybrid 4-mic systems), driver diaphragm material (Titanium composite, Beryllium plating, or DLC), and localized compliance verifications.
