The same product needs different preparation depending on where it is sold. This page sets out what each channel actually requires, starting with the numbers that decide whether a carton can even ship.
K1's packaging was designed before FBA was a consideration, and it happens to fit the constraints well. The numbers that matter:
| Requirement | K1 |
|---|---|
| Single shipping box weight limit (US) | 13 kg per master carton against a 22.7 kg (50 lb) limit — comfortably inside it, so no split packing is needed |
| Units per shipping box | 100 pcs, which makes multi-node distribution arithmetic simple |
| Retail unit size | 185 × 98 × 25 mm — small enough not to trigger oversized-tier fees |
| Unit gross weight | 120 g |
| Compliance documents | FCC-ID for the US, CE and RoHS for the EU; GPSR responsible person needed for EU listings |
| Barcodes | FNSKU applied by the seller, or we can print and apply per carton on request |
Rather than publish a wholesale price and let you guess, here is the structure to model it yourself:
| Revenue | Your listing price. The market retail reference is USD 49.9, which is where the category sits, not a required price. |
|---|---|
| Less referral fee | Typically 15% of the sale price on consumer electronics accessories. |
| Less FBA fulfilment | Charged by size tier and weight. At 120 g gross and a small box, this lands in the lowest tier — the packaging was chosen well for this. |
| Less storage | Monthly, by volume. 0.055 m³ per 100 units is a small footprint, which keeps long-term storage fees low. |
| Less landed cost | Unit price plus freight plus duty plus the per-unit share of certification and compliance. |
Two of those five lines are decided by packaging, and both are in your favour on this product. That is a more useful thing to know than a discounted unit price.
Airport retail is where this product's form factor earns its keep: a small box, a visible novelty and a price under the impulse threshold.
| What works | 185 × 98 × 25 mm stands on a counter and hangs on a peg. The case with earbuds docked is understandable in one glance, which is the entire requirement for a shelf three metres from a moving passenger. |
|---|---|
| What must be added | Multi-language packaging and a multi-language manual. Duty-free operators in different regions expect the local language on the box; the manual can carry several. |
| What is required administratively | Duty-free operators normally buy through a local distributor or require a local entity. Direct supply from Shenzhen is possible but usually goes through a consolidator, and the terms are set by them. |
| What to watch | Airport retail tolerates a higher unit price than high-street retail and punishes slow stock turns. Order depth should follow the passenger mix, not the total footfall. |
Hotels, resorts and serviced apartments use translation earbuds in two ways: issued to front-desk staff, or lent to guests.
One device per staff member, one licence code each, configured for the guest-source languages of that property. Hands free at a counter, private, and no shared device to sanitise between shifts. This is the model that works without any operational changes.
Needs a check-out and return process, a plan for lost units, and a decision on whether the licence code travels with the unit. Workable, but it is a logistics project rather than a product purchase. Worth planning before the first order, not after.
IPX5 helps here more than it does in retail: a device that lives on a counter gets splashed. The 45 g complete weight matters too — staff wear it for a whole shift.
Gifting is the channel where customisation pays for itself, because the box and the logo are the product.
| Minimum | 1,000 pcs per colour for a custom logo on the case and the box. A four-colour gift programme is 4,000 pcs. |
|---|---|
| What to customise first | The retail box. It is what the recipient sees before the product, and print setup is charged once per design. |
| Certification position | Gifting is usually domestic or single-market, so the certification burden is lower than retail. Cross-border air freight still needs the battery transport documents, and that is where gift programmes most often stall. |
| Timing risk | Gift programmes have fixed dates. Plating runs colour by colour, so a four-colour programme placed late will run late. Leave the full lead time in the plan rather than compressing it. |
Three arrangements exist for a distributor, and all three are about protecting the margin of the distributor rather than about price:
Those five answers are usually enough to quote the same day and to flag problems before they become returns.
Do you supply Amazon FBA sellers?
Yes. The master carton is 13 kg for 100 pcs, comfortably within the 22.7 kg single-box limit, and the retail box at 185 × 98 × 25 mm does not trigger oversized-tier fees.
What is the carton weight and configuration?
408 × 263 × 513 mm, 100 pcs per carton, 13 kg gross, 0.055 m³. A 20GP holds about 48,000 pcs and a 40HQ about 110,000 pcs.
Can the retail box be customised for duty-free or gift channels?
Yes. Custom box design and print start at 1,000 pcs, with print setup charged once per design.
Do you offer regional exclusivity?
Territory arrangements are discussed against volume and commitment. The mechanism that makes them enforceable is the licence code: a unit activated outside its agreed region can be identified.
Is the retail price fixed?
No. USD 49.9 outside mainland China and CNY 349 in mainland China are market reference prices. Resellers set their own price.
Can you print barcodes or FNSKU labels on the cartons?
Yes, on request. Tell us the label specification with the order so it is applied during packing rather than after.
Tell us the channel and the country. We will come back with the certification position for that market and a volume-tier quotation.
