The ATTACK SHARK X820 Ultra 75% Tri-Mode Gasket Mechanical Keyboard is a compact, feature-rich keyboard built for clean setups, smooth typing, and flexible multi-device use. Its 75% ANSI layout keeps dedicated arrow keys and essential controls while staying space-efficient for gaming desks, productivity setups, and travel-friendly workstations.
A standout feature is the 0.85-inch TFT smart display paired with a metal control knob, giving you real-time visual feedback for RGB control, OS switching, battery level, date, and connection status. Combined with Tri-Mode connectivity (2.4G wireless, Bluetooth 5.0, USB-C), a 4000mAh battery, and an upgraded gasket-mounted structure with multi-layer acoustic tuning, the X820 Ultra delivers a refined feel, cleaner sound, and easy customization through hot-swap sockets and QMK web driver support.
