Attack Shark X820Ultra 75% Wireless Mechanical Keyboard - Gasket Thock

Our review of the Attack Shark X820Ultra finds a 75% wireless mechanical keyboard aimed at gamers and keyboard enthusiasts who want a premium typing sound and flexible connectivity. The single biggest reason to buy is its balanced combination of a tuned gasket mount with a five-layer sound dampening system that produces a deep, thocky acoustic profile while keeping case ping and rattle to a minimum. It also delivers tri-mode connectivity and hot-swappable sockets, so users can quickly switch switches or devices without tools.

Key Features

• Tri-Mode Connectivity: Bluetooth 5.0, 2.4GHz wireless and wired USB-C options allow seamless switching between multiple devices and low-latency gaming.
• Hot-Swappable Sockets: Pre-lubed premium linear gift switches are installed and the PCB supports most 3/5-pin switches so users can customize feel without soldering.
• Advanced Sound Dampening: The tuned five-layer foam stack combined with a gasket mount reduces case ping and yields a clean, HIFI acoustic feedback ideal for typing and streaming.
• Custom TFT Screen and Knob: A programmable TFT shows date, time and battery and the CNC knob provides intuitive volume control and menu access.
• Durable Build: FR4 glass fiber PCB, textured PC plate and factory-lubed stabilizers give consistent, wobble-free keystrokes and long-term reliability.
• Cloud Driver Support: Web-based cloud software handles macros, key remaps and RGB or GIF customization without local installs.

Who It's For

The X820Ultra is best for PC gamers and keyboard hobbyists who prioritize sound and typing feel as much as wireless flexibility. If you value a deep, thocky acoustic profile and want to swap switches frequently, the gasket mount and hot-swap support make this a strong choice.

This is less ideal for someone who needs a compact 60% layout, or for users who prefer a completely silent, mousse-damped typing experience; the X820Ultra emphasizes a premium sound signature rather than muted silence.

Pros & Cons

• Cloud driver and TFT screen make RGB and macro setup straightforward across devices.

Cons

• Heavier acoustic profile may not suit users seeking a very quiet or ultra-soft typing feel.
