Clear Answers Before You Commit.

Start with the target customer, sales channel, price position and primary sleep concern. We can compare light-therapy lamps, smart pillows and sleep earplugs, then recommend models and configurations for sample review.

Both are light-therapy platforms. The most suitable choice depends on the intended placement, appearance, feature configuration and target price. Ask our team for the current model comparison and specification sheets before selecting a sample.

WP100 combines ergonomic support with integrated light, sound and vibration functions. The final application should be reviewed around guest instructions, operating simplicity, room setup and the experience your brand wants to provide.

Comfort, case size, ear-tip fit, product presentation and required functions all affect model selection. We recommend comparing Y33, Y33A and Y38 through specifications and samples rather than selecting by appearance alone.

Review the model-specific specification, available test information and a physical sample in the intended use scenario. Exact performance varies by model and configuration, so approval criteria should be agreed before production.

Product classification depends on the model, claims, target market and applicable regulations. We do not recommend making medical claims without the appropriate review. Tell us your destination market so the available documentation can be checked for that project.

For the models currently shown on this website, the usual starting MOQ is 1,000 pieces for S19, S19 Pro and WP100, and 3,000 pieces for Y33, Y33A and Y38. Final MOQ depends on configuration, packaging and material requirements and will be confirmed in the quotation.

Yes. Sample availability, cost, configuration and timing are confirmed case by case. Share the product model, target market and required changes so our team can recommend the appropriate sample path.

OEM projects normally adapt an existing product platform with agreed branding, color, packaging or configuration. ODM projects involve a broader product-development scope. Feasibility, development work, cost and schedule are reviewed before the project starts.

These options can usually be reviewed, but the available scope depends on the model, quantity, materials and target-market requirements. Artwork, color references, packaging structure and manual content must be approved before production.

Lead time depends on sample approval, quantity, material readiness, customization and packaging. We provide a project schedule after the requirements are clear; the confirmed delivery terms belong in the quotation and order documents.

Available files vary by product and market. Gold Rose provides a public certifications page with BSCI, CE, EPR, FDA-related registration documentation and RoHS files for review. Product-specific applicability should always be confirmed before ordering.

The project can include incoming-material checks, in-process inspection, function checks, appearance review and agreed reliability testing. The exact inspection criteria and any third-party inspection requirements should be recorded before production.

Project information is shared with the relevant team for quotation, development and production coordination. If your project requires an NDA or specific confidentiality terms, raise this before sharing sensitive design files so the terms can be reviewed.

After-sales handling depends on the product, order terms and the issue identified. Inspection records, photos, videos and batch information help the team investigate efficiently. Responsibilities and resolution terms should be stated in the order documents.
