The ATTACK SHARK x AJAZZ AK820 is a wired 75% mechanical keyboard with an 81-key ANSI layout, arrow and function keys kept, and a CNC aluminum knob for volume and backlight control. Its gasket mount sits on five layers of damping foam, which gives a softer, quieter, less hollow typing sound than typical tray-mount budget boards. It suits desk-space-conscious typists and gamers who want a compact wired board with a knob, but it lacks wireless and hot-swap flexibility found on some rivals. Owners rate it highly for feel and sound at its tier.

Buyers rate the AK820 highly, praising its thocky sound, comfortable gasket feel and the useful aluminum knob. Complaints center on the wired-only design and the lack of hot-swap.
The AK820 is a wired mechanical keyboard with a compact 75% ANSI layout and 81 keys. It keeps the arrow keys and function keys while taking up less desk space. A CNC aluminum knob adjusts the volume when rotated and toggles the backlight when pressed.
It uses a gasket-mount structure with five layers of sound-dampening material: PORON sandwich cotton, an IXPE switch pad, PET foam, sponge case foam and a bottom silicone pad. These layers reduce cavity noise and give a deeper sound. The single-key slotted PCB design improves key stability.
The keyboard comes with pre-lubed Moon Yellow linear switches. The double-shot PBT keycaps resist oil and shine over time. South-facing RGB LEDs light the keys evenly and do not interfere with custom keycaps. Companion software customizes lighting effects and creates macros.
