Translation earbuds are often marketed as "AI" without saying where the AI runs. On K1 it runs in the cloud: the earbuds capture speech, the app sends it to a large language model, and the result comes back. This page states the arrangement plainly, because distributors get asked about it in every market.
| Question | Answer |
|---|---|
| Which model, overseas | ChatGPT. |
| Which model, mainland China | Doubao, Tongyi or DeepSeek. |
| How the model is chosen | Configured by region at the factory before shipment. The reseller does not set it, and does not need to reconfigure a unit for its destination. |
| Does it run on the device | No. No model runs locally. The earbud hardware — a 30 mAh cell and a Bluetooth audio chipset — could not host one. |
| Does it need a network connection | Yes. Translation and AI both require a data connection through the phone. |
| Does it need the app | Yes, activated with one licence code per unit, bound to that pair of earbuds. |
Ask a question by voice or by typing, get an answer. Routed to the regional model. This is the function buyers most often demo, and the one that depends most on the connection quality.
Real-time transcription of speech into text, with editing, playback speed control and audio export. The practical use is meeting notes and site records, where the transcript matters more than the recording.
The other party joins through a shared link in a browser with no install, and reads subtitles during the call. Removes the "they will not install an app" objection entirely.
Camera text recognised and translated in 118 languages: menus, signage, labels, nameplates and instruction sheets.
Each unit ships with one licence code that activates the app and binds it to that pair of earbuds. It is not a marketing gimmick — it is what makes the following possible:
| Warranty claims | A claim can be traced to a production batch instead of being argued from a purchase date. |
|---|---|
| Returns | A returned unit can be checked for whether its code was activated, which distinguishes a fault from a change of mind. |
| Channel control | A unit sold outside its agreed region can be identified, which is how a distributor's territory is actually protected. |
Licence codes are issued per unit and cannot be reset by the reseller. If a code is lost or a unit is replaced, the replacement is issued against the original order reference.
Does the TalkShell app use ChatGPT?
Yes, in overseas markets the AI assistant routes to ChatGPT. In mainland China it routes to Doubao, Tongyi or DeepSeek. The route is configured by region at the factory before shipment.
Is this an offline translator?
No. The AI and translation models run in the cloud, not on the device. A data connection is required for translation and AI functions; without one, the earbuds work as ordinary Bluetooth earbuds.
Can I use the AI functions without internet?
No. Translation and the AI assistant both need a data connection. Music playback and calls over Bluetooth continue to work without it.
Do I have to configure the AI provider myself?
No. The provider is set at the factory according to the destination region, so a unit shipped to Europe does not need reconfiguration by the reseller.
Does the other person need the app for call translation?
No. They open a shared link in a browser and read subtitles during the call. Only the K1 owner needs the app and a licence code.
Where does the audio go during translation?
To the cloud language model configured for the region. The app's privacy notice governs what is retained; request the current notice with your order.
Tell us the destination country so the AI route and language packs are configured correctly, and we will send a unit you can test on a live call.
