Keychron Q4 Mechanical Keyboard

The Keychron Q4 US is a compact 60% mechanical keyboard designed for users who want a customizable, all-metal build with low latency and flexible key mapping. It suits hobbyists who swap switches, Mac and Windows users needing dual layouts, and gamers requiring fast response times. The Q4 focuses on typing feel, sound control, and firmware customization through QMK/VIA support.

Key Features

• Hot-swappable switch sockets allow easy switch replacement without soldering, supporting both 3-pin and 5-pin MX-style switches.
• QMK and VIA firmware compatibility enables extensive key remapping, macros, and shortcuts for personalized layouts.
• Dual system toggle with included keycaps supports both macOS and Windows layouts, saving two different configurations.
• South-facing RGB LEDs improve backlight visibility with non-shine-through PBT keycaps and avoid interference with various keycap profiles.

Build Quality

• Full CNC machined 6063 aluminum body offers a solid, durable frame with a double gasket design that reduces metal resonance and typing noise.
• Steel plate mounting combined with silicone pads between top and bottom cases enhances typing sound and keyboard flexibility.
• Screw-in PCB stabilizers increase stability for larger keys, reducing wobble and making upgrades easier.

Typing Experience

• Pre-lubricated Gateron G Pro switches provide smoother key travel and less wobble out of the box.
• OSA profile double-shot PBT keycaps resist oil and fading, offering a comfortable and durable typing surface with a shape between OEM and SA profiles.
• The double gasket and silicone pad design help lower typing noise without sacrificing key feel.

Compatibility and Connectivity

• Wired connection via USB Type-C ensures stable and low-latency input, suitable for gaming and productivity.
• Supports multiple ISO layouts, including UK, German, Nordic, Swiss, French, and Spanish, with barebone options for other ISO countries.
• Compatible with macOS and Windows systems, with dedicated keycaps and system toggle for easy switching.

Trade-offs

• No wireless connectivity, limiting use to wired setups only.
• 60% layout lacks dedicated function row and arrow keys, which may reduce convenience for some users.
• Sharper top case corners improve keycap compatibility but may feel less rounded compared to other designs.
