馃摫 1.65鈥?Smart TFT Dashboard

Most keyboards have a status LED. The K98 Pro has a 1.65鈥?TFT color display running at 142脳428 OPX resolution. Use it to monitor real-time system stats, track keystrokes, swap between profiles, and watch dynamic sci-fi animations that match the Phantom Black aesthetic. It鈥檚 your desktop command center 鈥?functional, immersive, and unlike anything else in its class.

鈿?Dual 8KHz Polling Rate 鈥?Wired and Wireless

Most keyboards that claim 8KHz only deliver it over USB. The K98 Pro delivers a true 8000Hz polling rate in both wired and 2.4GHz wireless modes, cutting input latency to a near-instantaneous 0.1ms. Whether you鈥檙e plugged in for a tournament or running wireless for a ranked session, the K98 Pro never gives up its competitive edge. Bluetooth 5.4 is available for flexible everyday use.

馃敭 GravaStar UFO Mechanical Switches

Developed in-house and co-engineered with Kailh, the GravaStar UFO Mechanical Switches are factory pre-lubed linear switches built for enthusiasts who don鈥檛 want to mod their keyboard before they can enjoy it. Smooth from the first keystroke, with a 45gf actuation force, 1.2mm pre-travel, and 3.5mm total travel 鈥?fast enough for competitive gaming, refined enough for all-day typing. Rated for 70 million keystrokes. Four sample switches from the GravaStar enthusiast pack are included so you can explore alternatives.

馃攰 Pure 鈥淭hocky鈥?Acoustics 鈥?No Modding Required

The K98 Pro鈥檚 5-layer foam gasket mount is one of the most advanced acoustic systems in its price range:

• Poron Case Foam 鈥?Absorbs chassis resonance at the source
• IXPE Switch Pad 鈥?Dampens switch-level vibration for a cleaner sound profile
• PET Film 鈥?Adds structural rigidity while reducing flex noise
• Slow-Rebound Poron 鈥?Creates the soft, bouncy gasket feel that enthusiasts spend hours modding for
• Gasket-Mounted FR4 Plate 鈥?Holds each switch firmly while allowing the plate to flex naturally

The result: a deep, creamy thock right out of the box. No foam stuffing. No tape mod. No lubing. Just open the box and type.

馃攱 228 Hours. Game Without Limits.

The 8000mAh rechargeable battery delivers up to 228 hours of wireless use in 1K polling mode with RGB off 鈥?or 166 hours in full 8K wireless mode. In practical terms, that鈥檚 weeks of daily gaming sessions between charges. When you do need to top up, the included USB-C braided cable handles it fast. Battery anxiety is not a feature of the K98 Pro experience.

馃寪 Tri-Mode Connectivity 鈥?Your Setup, Your Rules

• 2.4GHz Wireless (8KHz) 鈥?The primary competitive mode. Lag-free, ultra-responsive, with the included high-speed wireless receiver
• Bluetooth 5.4 鈥?Ultra-stable wireless for multi-device setups, laptops, and tablets
• USB-C Wired (8KHz) 鈥?Zero-latency wired connection with the included 1.6m premium braided Type-C cable

馃帹 19 ARGB Effects + 4 Ambient Side-Light Modes

The K98 Pro鈥檚 RGB system goes beyond standard backlighting. 19 built-in ARGB backlight effects illuminate the Phantom Black keycaps from below, while 4 ARGB ambient side-light modes cast a glow across your desk surface. Configure every effect, color, and brightness level through the web-based driver 鈥?no software to install, no account to create. Just open your browser and customize.

馃捇 Zero Bloatware 鈥?Web-Based Driver Platform

The K98 Pro is configured entirely through GravaStar鈥檚 browser-based driver platform. Remap keys, program macros, tune RGB profiles, and adjust polling rate 鈥?all from any browser on any device.
