Know before you buy
The 75% layout features 81 keys, meaning it removes the dedicated number pad found on full-sized keyboards while retaining essential navigation keys like arrows and function rows. This saves significant desk space for mouse movement without sacrificing the functionality needed for most productivity tasks.
Yes, the K687 Pro is hot-swappable, meaning you can pull out the existing switches and plug in new ones without any soldering. It supports both 3-pin and 5-pin mechanical switches, giving you full freedom to customize your typing experience.
The internal dampening layers are designed to absorb vibrations and hollow sounds often found in mechanical keyboards. This results in a more muted, refined 'thock' sound profile rather than a sharp, metallic click, making it ideal for shared office spaces.
Yes, the K687 Pro is compatible with both Windows and macOS. You can easily switch between operating systems, though you may want to use the software to remap specific keys if you prefer a native Mac layout.
The CNC aluminum case provides a premium, heavy-duty feel that prevents the keyboard from sliding or flexing during intense typing sessions. At 1800g, it is significantly sturdier than plastic alternatives and offers a more stable, high-end typing experience.
You can connect via a wired USB-C cable for zero latency, use the 2.4GHz wireless dongle for a stable gaming connection, or pair via Bluetooth to connect to multiple devices like tablets or laptops. This allows you to switch between your desktop and mobile devices seamlessly.
