Key Features

- Be ready to multitask without missing a beat by connecting the K3 with up to 3 devices via the stable Broadcom Bluetooth 5.1 chipset and switch between your laptop, PC, tablet and phone seamlessly. *Keep the distance between the keyboard and the device within reasonable limits to minimize signal interference.
- With a unique Mac layout, the K3 has all the necessary Mac multimedia keys while still being compatible with Windows. Extra keycaps for both Windows and Mac operating systems are included. *If it doesn't match your device exactly, you can try updating the keyboard's firmware.
- The redesigned low-profile Keychron mechanical switch is 40% slimmer than conventional switches with a shorter pre-travel and total travel distance that triggers an input and feedback faster than conventional/normal-profile mechanical switches.
- Together with the reinforced aluminum body (plastic bottom frame) make the K3 one of the thinnest and lightweight wireless mechanical keyboards on the market. The K3 also comes with a floating keycap design with a charming white backlight with modern keycap legends to sync with your mood.
