It is best for home office users, light gamers, and anyone who wants wireless Bluetooth convenience plus a wired USB-C fallback.

Who It's For

The K2 suits people who want a smaller keyboard that keeps essential keys and multimedia controls, such as remote workers, students, and content creators who switch between Mac and Windows devices. Its hot-swappable design appeals to keyboard enthusiasts who want to tune the feel without soldering, and the Bluetooth multi-device support is useful for users juggling a laptop, tablet and phone.
