Four in-house categories cover the fastest-moving smart wearable segments of 2026. Every model below is currently in production at ZUMU Technology Co., Ltd., with engineering files, firmware and APP branding available for buyer customisation.
Screenless bracelets remain our highest reorder category because they eliminate the two most common RMA causes in entry-level wearables — cracked glass and screen ghosting. Both models below carry a Declaration of Conformity and are validated for continuous heart-rate and sleep tracking.
A giftable, screenless fitness tracker with AI-generated health reports, built for retail chains and promotional programmes.
Cost-optimised variant for volume programmes where budget and battery life outrank premium materials.
We are not a listing-only trader. Product definition, firmware integration, pilot-run validation and packaging engineering are handled by our own team in Shenzhen — which is why specification changes can be confirmed within days instead of weeks.
Smart rings, AI glasses, camera earbuds and watches only. Concentrated tooling means faster mould reuse and lower customisation cost per SKU.
Incoming material check, SMT AOI, 48-hour aging, waterproof tank test and full-function final inspection — results archived against your PO number.
Sample from 1 piece on stock models, trial order from 50, and full private-label programmes from 3,000 pieces per colourway.
Stock models ship in days; customised builds follow a confirmed production calendar with weekly progress photos and video.
Declaration of Conformity plus CE / RoHS / MSDS / UN38.3 test reports arranged on request, with HS-code and labelling guidance.
One dedicated English-speaking contact from quotation to after-sales, supported by an in-house engineer for technical questions.
This is the exact sequence we follow with distributors, telecom retailers and promotional-gift buyers. Each stage ends with a written confirmation so nothing moves forward on assumptions.
Target market, sensor set, battery, certification scope and landed-cost target are captured in one specification sheet.
Our hardware team confirms feasibility, mould reuse options, firmware workload and realistic delivery windows.
Functional sample with your logo, UI theme and packaging draft; changes logged and re-sampled where needed.
Pilot batch validates yield and assembly SOP before mass production starts on the confirmed calendar.
Final inspection report, packing list, conformity documents and photo/video evidence released before dispatch.

ZUMU Technology Co., Ltd. was established in 2020 — a year confirmed on-site by third-party verification — and has operated continuously on international B2B channels for six years. Our team focuses on understanding what resellers actually need: stable firmware, honest battery figures, packaging that survives freight, and after-sales answers that arrive the same working day.
We serve importers, e-commerce sellers, telecom accessory chains and corporate-gift buyers across North America, Western Europe, Eastern Europe, Southern Europe and the Middle East. Business scope covers manufacturing, trading and OEM service with buyer-label support.
Declaration of Conformity OEM Service Offered Buyer Label Offered Each buyer is assigned one account manager who stays with the project from specification to after-sales, so product history and packaging decisions are never lost between departments.
The answers below reflect what our team confirms most often during quotation and pre-shipment stages.
MOQ depends on the product line and customisation depth. Ready-stock smart rings start from 1 piece for sampling, AI glasses and camera earbuds from 50 pieces for trial orders, and fully customised smart watches with private packaging typically start from 3,000 pieces per model and colourway.
Yes. OEM service and buyer-label service are both offered. Customisation covers logo laser engraving, watch faces and UI themes, dedicated APP branding, firmware language packs, retail box artwork and multilingual manuals. Engineering feasibility is confirmed in writing before sampling starts.
Smart rings are validated at 5ATM and watches at IP67 or IP68 using pressure-tank and spray testing on batch samples. Every production batch also passes drop, salt-spray and 48-hour aging tests, and the resulting inspection sheet is issued with your shipment documents.
Our main markets are North America, Western Europe, Eastern Europe, Southern Europe and the Middle East. Because these regions have different radio and labelling requirements, we confirm the destination country at quotation stage and align firmware, plug type and certification scope accordingly.
Standard export packs include the Declaration of Conformity, commercial invoice, packing list and HS-code guidance. Radio, battery and material test reports such as CE, RoHS, MSDS and UN38.3 can be arranged on request, and battery shipments follow air or sea dangerous-goods packing rules.
Ready-stock models dispatch within a few working days. Customised builds follow a confirmed production calendar after pilot-run approval, with weekly photo and video updates so you can plan marketing launches and inbound logistics with confidence.
