This 75% layout keyboard is crafted to provide a compact yet comprehensive typing experience, making it ideal for those who need more desk space without sacrificing essential keys. It features a unique combination of advanced design elements and user-friendly features, such as a convenient control knob and customizable backlighting. With its robust build quality and hot-swappable switches, the K687 is perfect for users who want a durable, customizable keyboard that can adapt to their specific needs.

Product Highlights

The Redragon PENUMBRA K687 stands out in the market with its innovative design and premium features. One of its most notable highlights is the gasket design, which replaces traditional screw fixing with precision-locked covers and gaskets. This design not only reduces noise but also provides a softer and more flexible typing experience. The keyboard is equipped with a CNC aluminum frame, ensuring a steady and elegant presence on any desk. The 81-key layout retains the functionality of a full-sized keyboard while eliminating the numpad, offering more space for mouse movement. Additionally, the inclusion of a control knob allows for easy adjustment of backlight brightness and media controls, enhancing user convenience. The K687's hot-swappable switches and customizable software options further set it apart, allowing users to tailor the keyboard to their preferences.

Craftsmanship and Design

The PENUMBRA K687 is a testament to superior craftsmanship and thoughtful design. Its body is constructed from tank-solid CNC aluminum metal, providing a premium and durable feel. The advanced frosted finish adds an elegant touch, making it a stylish addition to any setup. The 75% ANSI layout is compact yet functional, offering a perfect balance between size and usability. The keyboard's ergonomic design ensures comfortable typing, while the gasket-mounted structure reduces noise and enhances typing feedback. Overall, the K687 is built to withstand extensive use, making it a reliable choice for both work and play.

Connectivity Options

The Redragon PENUMBRA K687 offers a straightforward wired connectivity option, ensuring a stable and lag-free connection for all your typing and gaming needs. The keyboard connects via a USB-C cable, providing fast data transfer and easy plug-and-play functionality. While it does not offer wireless connectivity, the wired connection guarantees uninterrupted performance, which is crucial for competitive gaming and demanding work environments. The USB-C interface also ensures compatibility with a wide range of devices and operating systems, making it a versatile choice for users who switch between different setups. The simplicity of its connectivity options makes the K687 an ideal choice for those who prioritize reliability and performance.

Tailoring Your Typing

The PENUMBRA K687 allows users to personalize their typing experience extensively. The keyboard is hot-swappable, enabling users to easily change switches without soldering, allowing for a customized feel and sound. The custom Dragon Chant switches provide a smooth linear travel and cushioned typing feedback, enhancing the overall experience. Users can also customize the keyboard's aesthetics with its vibrant backlighting options, which can be adjusted via the control knob or through the proprietary software. The software offers further customization, allowing users to create macros, remap keys, and design unique lighting effects. This level of personalization ensures that the K687 can be tailored to suit individual preferences, whether for gaming or productivity.

Beyond Basics

The Redragon PENUMBRA K687 goes beyond the basics with its thoughtful features and design elements. The inclusion of a control knob adds a layer of convenience, allowing users to adjust volume and media playback without needing extra keys. The keyboard's noise-dampening technology, featuring multiple layers of foam and silicone gaskets, ensures a quiet and satisfying typing experience. These additional features make the K687 not just a keyboard, but a comprehensive tool for enhancing productivity and enjoyment in both gaming and office settings.
