The FiiO KB3 Wireless is a compact 75% mechanical keyboard that combines serious typing performance with the freedom of wireless connectivity. Designed for those who want a premium typing experience without being tethered to a desk, the KB3 Wireless features Gateron G Pro 3.0 Yellow linear switches and a sophisticated gasket-mounted build that delivers a smooth, cushioned keystroke feel beloved by keyboard enthusiasts.
Wireless Connectivity
The KB3 Wireless offers flexible connection options, letting you switch between wireless and wired USB-C modes to suit your setup. A built-in rechargeable battery provides up to 18 hours of use with RGB lighting enabled, extending to 500 hours with RGB switched off, and over 2,000 hours in standby mode. Whether you are at your desk or moving between workspaces, the KB3 Wireless keeps up with your workflow.
Mechanical Switches and Build Quality
Fitted with Gateron G Pro 3.0 Yellow switches, the KB3 Wireless delivers smooth, linear keystrokes with a light 50g actuation force and a 4mm travel distance. The switches are hot-swappable, meaning you can replace them with your preferred 3-pin or 5-pin switches without soldering. The gasket-mounted plate design reduces vibration and produces a softer typing sound profile, making the keyboard comfortable for long sessions in shared spaces.
Compact 75% Layout
The 75% layout keeps the keyboard compact and tidy on your desk whilst retaining all essential keys including the function row, navigation cluster, and arrow keys. The layout supports both Windows and Mac operating systems, with clearly labelled dual-mode legends on the keycaps. A signature red anodised aluminium volume knob at the top-right corner provides tactile, step-free media and audio control.
RGB Backlighting and Customisation
Per-key RGB backlighting illuminates each switch individually, with vivid lighting effects visible through the translucent switch housing. The keyboard is fully compatible with VIA firmware, allowing you to remap keys, create custom layers, set macros, and design your own RGB lighting profiles to match your workspace aesthetic.
Construction and Compatibility
The KB3 Wireless features an aluminium-magnesium alloy case that gives it a solid, premium feel. At approximately 1,115g, it has a reassuring heft typical of quality mechanical keyboards. The USB Type-C port is used for both wired operation and charging. Compatible with Windows, Mac, iOS, and Android devices.
