Attack Shark X820Ultra 75% Wireless Mechanical Keyboard - Thocky

In this review of the Attack Shark X820Ultra 75% wireless mechanical keyboard, the bottom line is simple: gamers and productivity users who want a premium, customizable typing experience without soldering will find real value here. The keyboard's single biggest selling point is its combination of tri-mode connectivity and genuine hot-swap support, which lets users switch between Bluetooth 5.0, 2.4GHz dongle, and wired USB-C while trying different 3/5-pin switches. The build focuses on a refined acoustic profile and durable components, making it an attractive mid-price option for those who care about sound and feel.

Key Features

• Tri-mode connectivity: Switch seamlessly between Bluetooth 5.0, 2.4GHz wireless, and a wired USB-C connection for flexible multi-device use and minimal latency when needed.
• Hot swappable sockets: Built-in hot-swap support accepts most 3-pin and 5-pin switches so users can change switch type without soldering to tune feel and actuation.
• Advanced 5-layer damping: A tuned PORON sandwich, IXPE, PET, DEPDM foam and silicone stack plus gasket mount reduces case ping and delivers a satisfyingly thocky sound.
• Custom TFT screen and knob: A programmable TFT display shows date, time and battery, and the CNC knob provides quick volume and menu control for on-device adjustments.
• Long battery and cloud driver: A 4000mAh battery supports extended wireless sessions and a web-based cloud driver enables macros, remapping and RGB/GIF uploads without local installs.

Who It's For

The X820Ultra suits gamers and enthusiasts who value typing acoustics and customization; the gasket mount and five-layer foam package produces the deeper, low-resonance sound that many users describe as "thocky" and refined. It is also a good choice for professionals who need reliable tri-mode connectivity and full N-key rollover for accurate input during fast typing or gaming.

Those who want an ultra-compact layout with minimal learning curve will like the 75% form factor, but buyers who demand a full-size number pad or who require hot-swap support for exotic switch pinouts not listed may want to check compatibility first. If you prefer pre-built RGB profiles only via a local app, note that cloud driver workflow is web-based rather than a standalone installer.
