Explore our flagship OEM/ODM production lines engineered for international importers, brand owners, and cross-border distributors demanding superior acoustic performance and compliance.
Originating from corporate registration in 2015 in California, USA (TOZO INC, 100 N Citrus Street, Suite 310, West Covina, CA 91791), our enterprise has grown into a vertically integrated global leader in smart audio innovation and wearable device manufacturing. Guided by the core operational ethos "Tech Around You", our Chinese manufacturing hubs synthesize Western industrial design specifications with East Asia's hyper-efficient supply chain infrastructure.
Today, our consumer electronics portfolio spans high-resolution True Wireless Stereo (TWS) earbuds, hybrid active noise-cancelling over-ear headphones, ergonomic air/bone conduction open-ear audio gear, AMOLED smartwatches, and IPX8 waterproof Bluetooth speakers. Having served over 30 million discerning listeners across 200+ countries and regions, our enterprise maintains a multi-tier OEM/ODM service architecture engineered specifically for B2B procurement managers, global distributors, and retail channel buyers.
ISO9001 certified automated SMT production facilities with full traceability from chip-level inspection to final acoustic chamber testing.
Full international product compliance including CE, FCC, RoHS, REACH, TELEC, and KC certificates tailored for straightforward import customs clearance.
New Product Introduction (NPI) cycles delivered in as few as 35 days, including custom acoustic tuning, firmware branding, and custom packaging design.
Acoustic Engineering Credibility: Our product series continuously secure top-tier international honors including the MUSE Design Gold Award, International Design Awards (IDA) Gold, and CES Innovation honors. Validated by over 1.5 million direct consumer ratings, our supply chain guarantees sub-0.5% return rates across high-volume procurement contracts.
To establish a tangible competitive edge in international retail channels, modern noise-cancelling headsets must transcend basic passive isolation. Our R&D team leverages four foundational pillars of electro-acoustic technology:
| Acoustic Technology | Technical Benchmark | B2B Sourcing Advantage | Primary Target Audience |
|---|---|---|---|
| Hybrid Active Noise Cancellation | -45dB to -52dB Depth / 3.5kHz Width | Outperforms standard passive noise reduction; premium retail price margin. | Frequent Travelers, Office Commuters |
| LDAC Hi-Res Audio | 990kbps Transmission / 24-bit 96kHz | Meets audiophile benchmark standards; high customer satisfaction & low return rate. | Audiophiles, Premium Music Enthusiasts |
| Open-Ear Air/Bone Conduction | Directional Acoustic Wave / < 5.1g per earbud | Rapidly expanding market category; zero ear-canal fatigue. | Outdoor Runners, Cyclists, Remote Workers |
| Low-Latency Gaming Mode | 38ms - 78ms Ultra-Low Latency | Dual-purpose functionality (Music + Gaming) expanding user demographic. | Mobile Gamers, Esports Content Creators |
As a leading Chinese manufacturer and global exporter, we continuously monitor the structural shifts in international consumer audio demand. Importers and brand owners planning their 2026–2030 SKU roadmaps should align with the following macro technological trends:
Headsets are transitioning from passive audio playback equipment into intelligent voice computing platforms. Modern chipsets integrated with dedicated Neural Processing Units (NPUs) enable real-time multilingual translation, adaptive soundscape adjustments based on atmospheric pressure, and predictive acoustic tuning tailored to individual user ear canal geometry.
Immersive spatial audio is migrating from high-end cinema setups into mainstream TWS and over-ear form factors. Utilizing 6-axis gyroscopes and accelerometer sensor arrays, modern headsets dynamically recalibrate soundstage positioning in real-time, creating a realistic 360-degree acoustic environment essential for next-generation gaming, movies, and spatial computing apps.
Driven by user fatigue associated with traditional in-ear silicone tips, open-ear air conduction and clip-on earbud designs are experiencing exponential year-over-year sales growth. Future products seamlessly blend acoustic enjoyment with personal situational awareness, incorporating health monitoring sensors (such as optical HR and skin temperature sensors) directly into ear-hook structures.
Global buyer purchasing behaviors in China's electronics manufacturing hub have evolved from basic price-per-unit negotiation into strategic end-to-end supply chain integration. Successful distributors are leveraging the following sourcing strategies:
Distributors are consolidating purchasing by combining noise-cancelling headphones, AMOLED smartwatches, and RGB outdoor speakers under unified OEM branding to increase Average Order Value (AOV).
Adherence to EU recycled plastic mandates (PCR plastics), bio-degradable soy-ink packaging, and cobalt-free battery chemistries is becoming mandatory for tier-1 western retail distribution.
To mitigate inventory holding risk, international buyers favor factories offering flexible low-MOQ starting tiers (500–1,000 units) with rapid laser-engraved branding and customized localized user manuals.
Supply Chain Security Note: Working directly with a manufacturer boasting US corporate headquarters and established Chinese production facilities provides dual security: reliable Western legal contract alignment alongside cost-effective manufacturing scale.
To streamline your vendor evaluation process, our international sales department has compiled definitive answers to the most common questions raised by wholesale buyers, importers, and OEM brand partners:
For standard wholesale orders of neutral stock models, our MOQ starts at just 20 to 50 units. For custom OEM white-labeling (including custom logo printing, customized Bluetooth pairing name, and branded giftbox packaging), our standard starting MOQ is 1,000 units per model. Flexible low-MOQ trial programs are available upon consultation with our sales directors.
Every headset batch undergoes strict 100% automated electro-acoustic testing using SoundCheck and AP (Audio Precision) analyzers. We enforce a 4-stage Quality Control protocol: Incoming Material Inspection (IQC), In-Process Assembly Line Inspection (IPQC), Finished Goods Testing (FQC), and Outgoing Quality Assurance (OQA) sampling. Our factory defect rate is strictly guaranteed below 0.3%.
Our complete product portfolio fully complies with global market access directives. All shipments carry CE, FCC, RoHS, REACH, WEEE, and UN38.3 (battery transport) certifications. For specialized markets like Japan and South Korea, we provide TELEC (MIC) and KC certified SKUs upon request.
Yes. Our in-house software engineering team provides custom DSP EQ curve tuning to meet specific sound profile requirements (e.g., enhanced bass response, balanced monitor sound, or vocal clarity). Furthermore, we offer custom app development and integration services under your brand identity for both iOS and Android platforms.
Sample orders and trial shipments are dispatched within 3 to 7 business days. Mass production OEM orders typically require 25 to 35 calendar days depending on packaging complexity. We support versatile trade terms including EXW, FOB (Shenzhen/Hong Kong), DDP (Delivered Duty Paid), and CIF to all major international ports.
We provide a comprehensive 12-to-24 month factory warranty on all wholesale audio devices. Distributors can choose between spare unit RMA allocations (1% free spare units with bulk container orders) or localized warranty processing replacement options supported by our online RMA service center.
