# TalkShell K1

> TalkShell K1 is a 3-in-1 product that combines a MagSafe-compatible iPhone case,
> a pair of wireless translation earbuds, and an AI assistant app. The phone case
> itself is the earbuds' charging case — there is no separate charging box to carry.
> It supports the full iPhone 12 through iPhone 18 series. Android models are not supported.

TalkShell K1 is manufactured by a direct factory in Bao'an District, Shenzhen, China.
Injection moulding and final assembly are carried out in-house; vacuum electroplating is
done by a dedicated plating partner under our own colour standard. The mainboard, drivers
and batteries are bought-in components. OEM and ODM orders are accepted.
