Flagship · DS500

The screenless band your customers keep wearing.

DS500 skips the screen on purpose: no notification noise, just continuous tracking that the app turns into answers. It is the model we lead with — and the platform our partners build their brands on.

Energy ScoreA daily recovery score from sleep, heart rate, HRV, stress and activity — the answer to “how am I today?”

AI health reportsTrends summarized into readable reports with everyday guidance, so users keep opening the app.

Couple interactionDouble-tap the button and a partner band answers with a vibration and light signal — a small feature users talk about.

Family health sharingWith permission, family members can follow heart rate, steps and sleep trends — care that sells to households.

Design patents granted in China, the EU and the UK · CE, FCC and RoHS files complete — a flagship you can list without IP headaches.

Why Us

Early in, deep in, direct from the factory.

Early investment

Screenless-band R&D started in H2 2024, while the category was still a niche — so when demand surged in 2025, the tooling, structures and supply chain were already proven across 20+ projects.

Deep customization

Straps, finishes, colors, engraving, boot logos, Bluetooth names, languages and retail boxes — combined freely per model, with MOQs starting at 500 units.

Reliability, validated

18 whole-device and component tests — drops, immersion, salt spray, thermal shock, RF shielded-room checks — run through development, pilot and mass production.

Direct from the factory

You deal directly with the factory: one sales contact for pricing, samples, production and shipping, with no middlemen in between — whether you run a brand, a distribution business or a store.

Products

22 production models. Five families.

Every model is in production and available for OEM. Select a model for details and customization options; full spec sheets are available on request.

Customization item	Minimum order
Silk-screen printing / laser engraving (strap, case)	500 units
Startup / shutdown logo & Bluetooth name	1,000 units
Additional language (UI & manual)	3,000 units
Custom color retail box	3,000 units
Custom nylon strap (your pattern or color)	2,000 straps

Straps & materials

Woven and textured nylon, sports silicone, Milanese mesh and more — most models offer several strap materials and two-tone colorways.

Body finishes

Brushed metal, jewelry-style polished bodies, decorative stone options and color matching per model family.

Software identity

Your boot logo, your Bluetooth name, your language set — manuals are available in up to 31 languages on supported lines.

Samples first

Order samples of any model to verify fit, sensors and app behavior before committing to a production run.

Ordering

How ordering works

Inquiry & samples

Tell us the models and quantities you need — we reply within 24 hours with pricing. Samples of any model come first, so you can verify fit, sensors and app behavior before a production order.

Proforma invoice & 30% deposit

We issue a proforma invoice for your order. Scheduling starts on a 30% deposit by T/T; the balance is paid before shipment.

Production & QC

Your order runs under our ISO9001 system with 100% final inspection. QC photos and test reports are available before dispatch — or send your own inspector.

Balance & shipping

Once the balance is settled, we hand the goods to your forwarder or arrange shipping to your market, with export documentation ready for your channel.

Lead times

Stock models — neutral orders	H59, H59 MAX, DS05 and DS500 are kept in stock. Neutral orders (no customization) up to 200 units usually ship within 1–3 days; above 200 units, please confirm the schedule with us in advance.
Other models — neutral orders	For the remaining models we keep materials on hand, and neutral orders generally ship within 30 days. We confirm the production slot when your order is placed.
Customized orders	Custom orders run about 30 days after sample approval. We quote delivery as a window (for example Nov 25–30) with a built-in buffer for material and clearance steps — the window you plan around is the window you get.
Light customization on stock	Laser engraving or a Bluetooth-name change on a stocked model adds about 1–5 days.

ODM

New product development

We take on ODM projects: product design, hardware development, structural development, manufacturing and test validation. The app and cloud platform are usually developed by the brand itself.

Industrial design (ID)	About 3 days
Mechanical design (MD)	About 3–5 days
Tooling	About 30 days
T0 prototypes	About 5 days
Pilot production & validation	About 7–10 days
Mass production after sample approval	About 30 days
Repeat orders	1,000 units in about 22 days; 10,000 units in about 25–30 days, including material purchasing and production.

The first production run is scheduled as the project moves through these stages. MOQ and payment terms for ODM projects are confirmed per project, based on the final design, configuration and order quantity.

Factory & Quality

Validated like it matters — because returns don't lie.

Six standardized production lines under an ISO9001 quality system, a dust-free assembly environment, and a reliability program that covers whole devices and key components across development, pilot runs and mass production — including a shielded room for RF and communication consistency testing.

100% inspection

Every unit is checked across appearance, waterproofing, aging and software functions — incoming (IQC), in-process (IPQC) and finished-goods (FQC) gates, with firmware, heart-rate, temperature, QR and MAC checks before storage.

Component-level rigor

Batteries pass short-circuit, drop, humidity and thermal tests; speakers run 96 h continuous playback; LCDs are verified at 60°C / 90% RH — before any of them reach the line.

Export markets served

Europe, the Americas, Japan, Russia, South Korea and the Middle East — with compliance documentation and certification reports available for your channel.
