Its 75% layout provides 81 keys and a dedicated metal knob, offering a compact footprint without sacrificing essential functionality. The inclusion of hot-swappable sockets allows users to easily change mechanical switches without soldering, supporting both 3-pin and 5-pin options for maximum compatibility. One of the most notable aspects is its tri-mode connectivity, enabling effortless switching between wired USB-C, Bluetooth, and 2.4GHz wireless modes. This flexibility is ideal for users who frequently transition between devices or prefer different connection types for various scenarios. These features make the keyboard particularly appealing to power users who demand both high performance and the ability to tailor their typing experience. The combination of hot-swappability, advanced firmware support, and multi-device connectivity sets it apart in a crowded market.

Construction Details

Aesthetically, the keyboard boasts a modern, minimalist design with a compact 75% ANSI layout. The case is constructed from durable plastic, providing a lightweight yet sturdy feel. The plate is made from polycarbonate (PC), contributing to a soft, flexible typing experience, especially when paired with the gasket-mount structure. This mounting method, along with multiple layers of sound-dampening materials—including sandwich latex foam, IXPE switch pad, PET sound-enhancement pad, and bottom silicone—ensures a quiet and refined sound profile. The build quality is robust, designed to withstand daily use while maintaining a premium feel. The keyboard’s compact form factor makes it suitable for smaller desks or portable setups, while the thoughtful ergonomic considerations ensure comfort during long typing or gaming sessions.

Wireless and Wired Connectivity

This keyboard excels in connectivity, offering users multiple ways to connect to their devices. It supports tri-mode operation, allowing seamless switching between wired USB-C, Bluetooth, and 2.4GHz wireless connections. The USB-C wired mode ensures ultra-low latency and maximum polling rates of up to 1000Hz, making it ideal for competitive gaming or latency-sensitive tasks. The 2.4GHz wireless mode also delivers a high polling rate and low latency, providing a near-wired experience without the clutter of cables. The built-in 4000mAh battery offers impressive longevity, supporting up to 260 hours of use with RGB lighting off. Charging is efficient via the USB-C port, and the keyboard can be used while charging, ensuring no downtime. Switching between devices and operating systems is straightforward, making it a versatile choice for users with multi-device setups. Whether you are working at a desk, gaming on a console, or typing on a tablet, this keyboard adapts effortlessly to your workflow.

Personalization Options

Personalization is at the core of this keyboard’s design. With full QMK and VIA support, users can remap every key, create macros, and customize layers to suit their workflow or gaming preferences. The intuitive VIA software allows real-time changes without the need for firmware flashing, making advanced customization accessible even to beginners. The double-shot PBT keycaps ensure long-lasting legends and a premium feel, while the Cherry profile provides a comfortable typing angle. Users can further personalize their experience by swapping keycaps or switches to match their preferred sound and feel. The keyboard’s open firmware and hardware design make it a favorite among enthusiasts who enjoy tinkering and optimizing their setup. Whether you want a unique lighting scheme, custom macros for productivity, or a specific typing sound, this keyboard provides the tools to make it your own.

Special Features

Beyond its core capabilities, the keyboard includes several special features that enhance its usability and appeal. The dedicated metal knob offers tactile, programmable control for volume adjustment or other functions, adding a layer of convenience for multimedia use. Full N-key rollover and anti-ghosting ensure that every keystroke is registered, even during the most intense gaming sessions. The inclusion of multiple sound-dampening layers delivers a refined acoustic profile, reducing noise and providing a satisfying typing experience. These thoughtful touches make the keyboard not only powerful and customizable but also enjoyable to use in any setting.
