Customisation requests on a product like K1 fall into two groups: things that change a print file, and things that change a mould. The first group is cheap and quick. The second is neither. This page separates them before you ask for a quotation.
| OEM (private label) | ODM / NRE development | |
|---|---|---|
| What it is | Our existing K1 hardware and moulds, carrying your brand on the case, the retail box, the manual and the app configuration. | A product developed for you: new housing geometry, different driver, different battery, different chipset. |
| What changes | Print files, packaging, language packs, colour selection. | Moulds, mechanical design, radio design, and therefore all certification. |
| Minimum | 1,000 pcs per colour; 4,000 pcs for four colours or for a single-model run. | Project-based. Tooling and certification are charged as NRE before production. |
| Timeline driver | Plating and packaging. | Tooling, then re-certification. Certification is the long pole, not the mould. |
| Who this suits | A brand, retailer or distributor who wants their own label on a proven product. | A brand with a specification that no existing product meets, and the volume to pay for it. |
Most enquiries that arrive as "ODM" turn out to be OEM once the requirement is written down. If what you actually need is your logo, your packaging and your language packs, that is OEM and it starts at 1,000 pcs per colour.
| Item | Minimum | Notes |
|---|---|---|
| Logo on the case | 1,000 pcs per colour | Applied to the finished shell. Position and size confirmed from a proof before production. |
| Logo and design on the retail box | 1,000 pcs | The box is 185 × 98 × 25 mm with an inner tray. |
| Manual language | 1,000 pcs | Multi-language manuals are normal for this product; tell us the market and the required languages. |
| Language packs preloaded | 1,000 pcs | 165 conversation languages are available; the preloaded set is configured per region at the factory so the reseller does not have to. |
| Colour selection | 1,000 pcs per colour | Four finishes are in production: Obsidian Black, Starlight Silver, Vibrant Orange, Rose Pink. |
| A colour outside the four | Subject to plating trial | Possible, but it needs a plating trial and a first-article approval, and the minimum rises because the trial load is a separate bath run. |
| AI provider routing | Configured per region | Overseas units route to ChatGPT; mainland China units route to Doubao, Tongyi or DeepSeek. Set at the factory, not by the reseller. |
These are locked by the mould or by the radio certification. Changing any one of them is a new project, not a customisation:
The shell and lid geometry, the two earbud docking channels, the earbud housing shape, and the camera cutout position. The case shell mould is single-cavity at a 43-second cycle; the lid and earbud housings run four cavities. A geometry change means a new mould.
The Bluetooth radio and antenna design, which sit under the FCC-ID and the CE radio assessment. Changing the chipset or the antenna invalidates both, and both have to be re-obtained before the product can ship.
Earbud cells are 30 mAh each and the case carries 150–230 mAh. A different capacity changes the charging board and the safety assessment.
The Φ6 mm, 16 Ω composite-diaphragm driver and the ENC microphone placement. A different driver changes the acoustic chamber inside a housing that has no spare volume.
Lead time is committed per order after steps 1 to 3 are settled. The three variables that move it most are the number of colours, whether packaging is custom, and whether the target market needs certification we do not yet hold.
Give us those five items in one message and the quotation is usually same-day. Enquiries that arrive as "what is your best price" without a quantity get a request for the quantity instead of a number, because the honest answer depends on it.
What is the minimum order for a custom logo?
1,000 pcs per colour. A run covering all four colours is 4,000 pcs, and a run restricted to a single iPhone model is also 4,000 pcs.
Can you change the shape of the earbuds or the case?
No, not as a customisation. The shell, lid and earbud housings are fixed by existing moulds, and a geometry change would also invalidate the FCC-ID and CE radio certification. It is possible only as a separate NRE development project.
Can I put my brand name in the app?
App branding and the store listing are handled separately from the hardware order. Tell us what you need and we will confirm what is possible for your market and volume.
Do you do full ODM development from scratch?
K1 itself is offered as OEM private label. Development of a different product is an NRE project with tooling and certification charged before production.
Can I order a colour that is not in the four standard finishes?
Yes, subject to a plating trial and first-article approval. The minimum rises because the trial is a separate plating bath run.
Will the app work in my country with the AI provider I expect?
The AI provider is configured per region at the factory: ChatGPT for overseas units, and Doubao, Tongyi or DeepSeek for mainland China. Tell us the destination country so the unit is configured correctly before it ships.
Send the five items listed above — models, colours, quantities, logo and target market — and we will quote against the correct volume tier.
