AJAZZ - AK820 Wired Mechanical Keyboard Black



Pairs well with
Compact 75% i layout with metal knob
The AJAZZ AK820 is designed in an ergonomic 75% layout (81 keys). This compact yet fully functional size frees up valuable desk space for your mouse while retaining access to a dedicated function key row and directional arrow keys. The design is enhanced with a solid, CNC-machined metal knob for quick and intuitive multimedia volume adjustment.


Gasket Mount architecture with five-layer sound dampening
The keyboard’s internal construction is based on innovative Gasket Mount technology. The main board is not rigidly screwed to the case, but cushioned instead. This effect is further enhanced by the use of as many as five layers of dampening materials (including a silicone bottom pad, Poron foam on the PCB, IXPE switch pads, and a PET layer). This system completely eliminates the hollow resonance of the case, delivering a deep and exceptionally “clean” acoustic profile with every keystroke.
Flexible Flex-cut structure (PC plate and PCB)
Both the polycarbonate (PC) mounting plate and the printed circuit board (PCB, 1.2 mm thick) feature dedicated Flex-cut slots beneath each individual key. This technological solution increases the natural flexibility and springiness of the entire internal structure, allowing the keyboard to respond softly to pressure and noticeably reducing strain on finger joints during long typing sessions or gaming marathons.


Dedicated switches with full Hot-Swap support
The keyboard is available with a choice of precise linear switches: classic Red Switch in the sleek Black model, or unique factory-lubed Sea Salt Switch in the Black-Gray-Yellow model. The hot-swap architecture (sockets compatible with 3-pin and 5-pin switches) provides complete freedom to test and replace switches without the need for a soldering iron.
PBT Keycaps, OS support, and South-facing RGB lighting
The durable Keycaps feature an OEM profile and are made from long-lasting PBT polymer using Double-shot technology. As a result, they are highly resistant to legend wear and the so-called “shine” effect on the material. The RGB lighting module (1.6 million colors) uses South-facing LEDs, ensuring excellent brightness and full compatibility by preventing lower Keycaps from hitting protruding LED lenses. The device also allows hardware switching between Windows and macOS layouts.
