The exact process may vary depending on whether you choose an existing private-label product or require deeper OEM/ODM customization.
Step 1 — Tell Us About Your Project
Every OEM project should start with the commercial requirements rather than simply choosing a model from a catalog.
When you contact Tashells Audio, the more information you provide, the more accurately our team can recommend a suitable solution.
Information We Recommend Providing
Product type
Target market or destination country
Estimated order quantity
Target price range
Required Bluetooth version or chipset, if specified
ANC / ENC requirements
Battery-life requirements
Audio and microphone requirements
Product color
Logo requirements
Packaging requirements
Required certifications or compliance documents
Target delivery date
Reference photos or existing product specifications, if available
If you do not have a complete specification yet, that is also fine. Tell us your target market, customer group, expected features, order quantity, and price positioning, and our team can help identify an appropriate starting point.
After understanding your requirements, we evaluate whether an existing product platform can meet the project needs or whether additional customization is necessary.
For many customers, starting from a mature ODM platform is the most efficient route because it can reduce development time, tooling investment, and technical risk.
Depending on your project, you can explore our main product categories:
Existing Platform / Private Label
This option is suitable for customers who want faster market entry and lower development risk.
Typical customization can include:
Logo printing
Product color
Charging-case color
Bluetooth device name
Retail packaging
User manual
Accessories
Selected firmware functions where supported
Deeper OEM / ODM Development
For more differentiated projects, we can evaluate requirements such as:
New product appearance
Structural modifications
New tooling
Component changes
Chipset or PCBA configuration
Battery configuration
Speaker and microphone requirements
Acoustic tuning
Firmware functions
Special accessories
Custom packaging structure
Feasibility, MOQ, development cost, and lead time depend on the actual requirements.
Step 3 — Quotation & Specification Confirmation
Once the product direction is clear, our sales and project team prepares the quotation according to the agreed configuration.
For an accurate comparison, we recommend that buyers do not evaluate FOB price alone.
The quotation and specification should clearly identify important factors such as:
| Item | What Should Be Confirmed |
|---|---|
| Product model | Final model / platform |
| Bluetooth solution | Chipset and Bluetooth version |
| Audio | Speaker and supported functions |
| ANC / ENC | Required noise-control configuration |
| Battery | Earbud and charging-case configuration |
| Color | Standard or customized color |
| Logo | Position and printing method |
| Accessories | Cable, ear tips and other included items |
| Packaging | Standard or customized packaging |
| Quantity | Final order quantity |
| Compliance | Documents/testing required for destination market |
| Trade terms | FOB or other agreed terms |
| Lead time | Based on approved configuration and order |
Any change in components, customization, packaging, or order quantity can affect the final quotation.
Step 4 — Sample Development
We strongly recommend sample evaluation before a bulk order.
Depending on the project, the sample may be:
Standard Product Sample — used to evaluate an existing model before customization.
Customized Sample — may include logo, color, firmware, packaging, or other agreed modifications.
Engineering / Development Sample — used when structural, electronic, acoustic, tooling, or other deeper development is required.
During the sample stage, our team coordinates the agreed product configuration and provides the sample for customer evaluation.
Step 5 — Sample Testing & Approval
The sample approval stage is one of the most important parts of the OEM process.
We recommend testing the product according to its intended use rather than evaluating only its appearance.
Recommended Sample Checks
Bluetooth pairing and connection stability
Music playback
Speaker performance
Microphone and call quality
ANC performance, where applicable
ENC/call noise reduction, where applicable
Transparency/ambient mode, where applicable
Touch controls or buttons
Charging performance
Battery performance
Earbud comfort and fit
Open-ear wearing stability, where applicable
Sound leakage for open-ear products
Product appearance and surface finishing
Logo appearance
Accessories
Packaging
Firmware functions
If changes are required, they should be communicated during this stage so that the final configuration can be confirmed before mass production.
Step 6 — Logo, Branding & Packaging Confirmation
For private-label customers, branding is an important part of turning a standard Bluetooth audio product into a market-ready product.
Depending on the model and project, Tashells Audio can support customization such as:
Product Branding
Logo on earbuds
Logo on charging case
Bluetooth pairing name
Product labels
Packaging
Custom color box
Logo and brand artwork
Product images
Barcode
Model information
User manual
Warning labels
Accessories arrangement
Shipping marks
Customers should provide final artwork in the required format. Our team will confirm the applicable printing area, packaging structure, and production requirements before mass production.
Step 7 — Pre-Production Confirmation
Before bulk production begins, the important project details should be frozen and confirmed.
Depending on the order, this can include:
Approved product model
Final specification
Approved sample
Final color
Logo artwork and position
Packaging artwork
User manual
Accessories
Product labels
Carton marks
Quantity
Quality requirements
Required compliance documents
Shipping requirements
This stage helps prevent avoidable differences between the approved sample and the mass-production order.
Step 8 — Mass Production
After the order requirements and approved configuration are confirmed, the project moves into mass production at our production facility in Fenggang, Dongguan, Guangdong, China.
Tashells Audio focuses on Bluetooth audio manufacturing for B2B projects. Our production capability supports bulk orders, while the actual production schedule is arranged according to the product model, customization level, component availability, quantity, packaging requirements, and current production plan.
Our previously established production capacity is up to approximately 200,000 pcs per month, depending on product mix and order requirements.
During production, our team coordinates components, assembly, product functions, branding, packaging, and quality requirements according to the confirmed order specification.
Step 9 — Quality Inspection
Quality control should be built into the manufacturing process rather than treated as a final step only.
Inspection requirements depend on the product and order, but Bluetooth audio products may be checked for areas such as:
Cosmetic appearance
Product assembly
Bluetooth pairing
Speaker function
Microphone function
ANC / ENC functions where applicable
Touch or button controls
Charging
Battery-related functionality
Indicator lights or displays
Logo and printing
Accessories
Packaging
Quantity and carton information
For custom orders, inspection should be based on the final approved specification and agreed quality requirements.
Customers may also arrange third-party pre-shipment inspection when required.
Step 10 — Packing & Shipment
After production and final inspection are completed, products are packed according to the approved packaging requirements.
Before shipment, the relevant commercial and shipping information is confirmed with the customer.
Depending on the order and agreed trade terms, shipment can be coordinated by the customer’s nominated forwarder or through an agreed logistics arrangement.
For products containing lithium batteries, applicable battery transportation documentation and shipping requirements should be confirmed according to the destination, transportation method, and final product configuration.
