Two wireless earbuds dock inside the case. The case is their charging case, so there is no separate earbud box to carry or lose. 165 languages for conversation, 118 for photo translation, an AI assistant, and full iPhone 12 through iPhone 18 coverage.
TalkShell K1 combines a protective iPhone case, a pair of wireless translation earbuds and an AI assistant app. The earbuds sit in two moulded channels inside the case and charge from the case battery while the phone is in your pocket. Nothing extra needs to be carried, and nothing extra needs to be charged separately.
150–230 mAh in the case shell recharges the two 30 mAh earbuds. USB Type-C input and wireless charging are both supported, so the case charges from the same pad as the phone.
Free talk with one earbud per person, handheld translator mode through the phone speaker, earbud-plus-phone mode, and simultaneous interpretation for meetings and lectures.
Voice and text AI conversation, real-time voice notes with transcription and audio export, and call translation where the other party joins by link without installing anything.

The language count matters less than whether the mode fits the situation. K1 covers the four situations buyers actually ask about. Which mode fits which room →
| Conversation translation languages | 165 |
|---|---|
| Photo translation languages | 118 |
| Free talk mode | One earbud worn by each person. Each speaks their own language and hears the other translated in the earbud. |
| Handheld translator mode | The phone speaker handles output, for speaking with someone who has no earbud. |
| Earbud plus phone mode | One person uses the earbud, the other uses the phone, useful over a counter or across a desk. |
| Simultaneous interpretation | For meetings, lectures and site visits where speech runs continuously. |
| AI assistant | Voice and text. Connects to ChatGPT in overseas markets and to Doubao, Tongyi or DeepSeek in mainland China, switching automatically by region. Cloud-based; not an offline translator. |
| Call and video call translation | Participants join through a shared link without installing the app; subtitles are displayed during the call. |
| Voice notes | Real-time transcription, editing, playback speed control and audio export. |
| Supported devices | iPhone 12, iPhone 13, iPhone 14, iPhone 15, iPhone 16, iPhone 17 and iPhone 18 series, including Pro, Pro Max and Plus. Android models are not supported. Model coverage and mould structure → |
The app is listed in app stores as Ear Dance and is activated with a licence code supplied with the product. It pairs the earbuds, selects the translation mode and holds the AI assistant. Language packs and the AI provider are configured per region at the factory, so a unit shipped to Europe does not need reconfiguration by the reseller. Where the AI actually runs →
One licence code per unit. The code activates the app and binds it to that pair of earbuds, which keeps returns and warranty claims traceable back to a production batch.
Free talk, handheld translator, earbud plus phone, and simultaneous interpretation — selectable per conversation rather than fixed at pairing.
The other party joins through a shared link over any messaging app and reads subtitles during the call. Nothing to download on their side.
Live transcription with editing and audio export, plus voice and text AI conversation through the same earbuds.
All four colours share the same shell geometry and the same mould, so a mixed-colour order does not require separate tooling.

|---|---|
| CE | European Union conformity |
| RoHS | Restriction of hazardous substances |

Are you a manufacturer or a trading company?
We are a direct manufacturer. Injection molding and final assembly of TalkShell K1 are carried out in our own facility in Bao'an District, Shenzhen, China; vacuum electroplating is carried out by a dedicated plating partner under our own colour standard. OEM and ODM orders are accepted.
What is the minimum order quantity for TalkShell K1?
Standard wholesale orders start at 3,000 pieces. Custom orders require a minimum of 1,000 pieces per color, and a custom run covering all four colors requires 4,000 pieces.
Which iPhone models does the K1 case support?
K1 supports the full iPhone 12 through iPhone 18 series, including Pro, Pro Max and Plus variants. Android models are not supported.
What certifications does TalkShell K1 hold?
K1 holds FCC-ID for the United States, CE and RoHS for the European Union, and a GB 4943.1-2022 test report for China. It has not obtained Japan MIC/TELEC or PSE certification, so the product is not offered for the Japanese market.
How many languages does the translation support?
165 languages for conversation translation and 118 languages for photo translation. There are four translation modes: free talk with one earbud worn by each person, handheld translator mode using the phone speaker, earbud plus phone mode, and simultaneous interpretation mode for meetings and lectures.
Does the case include a separate charging box for the earbuds?
No separate charging box is needed. The two earbuds dock inside the phone case and the case itself is the charging case, with a 150-230 mAh battery and support for both USB Type-C and wireless charging. The complete unit weighs 45 g.
Can I order K1 with my own logo and packaging?
Yes. Custom logo on the case and on packaging is available. The minimum for a custom logo order is 1,000 pieces per color, or 4,000 pieces for a run covering all four colors. Color selection and language pack configuration are also configurable.
Is the AI assistant offline or cloud-based?
The AI assistant is cloud-based and connects to large language models. In overseas markets it uses ChatGPT; in mainland China it uses Doubao, Tongyi or DeepSeek, switching automatically by region. It is not an offline translator and does not run a local model, so AI functions require a network connection.
