K2 75% Wireless Mechanical Keyboard - Gateron Red, RGB Backlit

Our review of the K2 75% Wireless Mechanical Keyboard finds it ideal for users who want a compact, premium-feeling board that keeps arrow and shortcut keys without a numpad. The biggest reason to buy is its blend of a sturdy aluminum frame, long battery life and reliable Bluetooth 5.1 multi-device switching, which together make it a great daily driver for home, office and light gaming. The keyboard balances solid build and satisfying linear Gateron G Pro Red switches with the convenience of both wireless and USB-C wired modes.

Key Features

• 75% layout: retains arrow and shortcut keys in a compact 84-key layout so you save desk space without losing essential navigation keys.
• Bluetooth 5.1 multi-device: can connect with up to three devices and switch between them quickly for seamless work across a laptop, tablet and phone.
• 4000 mAh battery: offers up to 72 hours of continuous typing or about a week of typical daily use, which reduces charging interruptions.
• Aluminum frame: gives the keyboard physical stability and a higher-end feel that customers mention positively for build quality.
• Gateron G Pro Red switches: linear switches rated for 50 million keystrokes that deliver smooth, quiet keypresses good for typing and light gaming.
• RGB backlighting: bright, attractive lighting with clear legends and multiple static and dynamic modes for low-light typing.

Who It's For

The K2 is well suited to professionals and creatives who need a compact mechanical keyboard that still provides dedicated arrow keys and function shortcuts, and who value a premium metal frame and long battery life. Its multi-device Bluetooth support and wired USB-C option make it flexible for people who switch between a laptop, tablet and smartphone.

It is also a good pick for light gamers who prefer linear red switches and want a compact tenkeyless experience. Those who need full N-key rollover in wireless mode for competitive gaming should look elsewhere, since NKRO is available on wired mode and wireless mode provides 6KRO.
