Keychron K3, a compact 75% layout ultra-slim wireless mechanical keyboard built for peak productivity and a great tactile typing experience. 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.
