Attack Shark X820Ultra 75% Wireless Mechanical Gaming Keyboard

Our review of the Attack Shark X820Ultra finds a compact 75% wireless mechanical keyboard that aims squarely at users who want a premium typing feel and flexible connectivity without a big price premium. The single biggest reason to consider the X820Ultra is its combination of tri-mode connectivity and a thoughtfully damped, gasket-mounted case that produces a noticeably clean, thocky sound profile while remaining hot-swappable for easy customization. It suits gamers and keyboard enthusiasts who value sound, feel, and convenience in one compact board.

Key Features

• Tri-Mode Connectivity: Switch seamlessly between Bluetooth 5.0, 2.4GHz wireless, and wired USB-C modes for reliable connections across PC, tablet, and mobile devices.
• Hot-Swappable Sockets: Factory-lubed linear gift switches with 3/5-pin compatibility let users change switches without soldering to personalize feel.
• Advanced 5-Layer Sound Dampening: A PORON sandwich, IXPE underpad, PET pad, DEPDM foam and silicone base combined with a gasket mount reduce case ping and produce a satisfying acoustic signature.
• Custom TFT Screen and Knob: A small programmable display shows date, time and battery status while the CNC knob gives quick physical control over volume and menu functions.
• Durable Build and Typing Consistency: FR4 glass fiber PCB with per-key flex-cut, textured PC plate and lubed stabilizers offer balanced keystrokes and low wobble.
• Long Battery and Cloud Driver: A 4000mAh battery supports extended wireless use and the web-based cloud driver enables macro, key remap and RGB/GIF customization without local installs.

Who It's For

The X820Ultra is ideal for gamers and hybrid workers who want a compact 75% layout with solid wireless performance and the option to tweak switches later. Enthusiasts who enjoy tuning acoustics will appreciate the 5-layer dampening and gasket mount that deliver a refined, thocky sound out of the box.

Those who need a full-size numpad or require software installed locally for enterprise environments may want to look elsewhere, and buyers seeking ultra-silent boards should note this model emphasizes a pleasing mechanical sound rather than complete silence.
