Ajazz AK820 75% Hot Swappable Mechanical Keyboard with Volume Knob
Product description
What it is and what it aims to solve
The Ajazz AK820 is a 75% compact mechanical keyboard designed to save desk space while keeping essential function keys within easy reach. Its standout features include a dedicated premium volume knob for quick audio control and a wired USB-C connection for stable, low-latency use. This layout is ideal if you want more room for your mouse without sacrificing standard keys.

Build and typing feel on paper
The keyboard uses a gasket mount construction with multiple damping layers, which aims to reduce hollow typing noises and deliver a solid, creamy thocky sound. The hotswap PCB supports both 3-pin and 5-pin switches, making it straightforward to customize switches without soldering. Factory-lubricated linear switches (the sea salt moonlight style or similar) are intended to offer smooth, quiet, and snappy keypresses right out of the box.

Keycap and lighting setup


Premium PBT keycaps with double-shot legends resist oil and wear, helping legends stay legible over time. The south-facing RGB design is configured to deliver bright backlighting, with about 20 predefined lighting modes plus driver-based customization for rhythm effects. This makes it flexible for both gaming aesthetics and a clean desk setup.

Who it’s for
If you value desk real estate, crave a strong typing feel, and want easy DIY customization, this could fit well. It’s a solid option for gamers who appreciate a compact footprint without giving up a practical number of function keys, and for desk setups that lean into a sleek, modern look.

What stands out, and where it might fall short
What stands out: gasket-mount design for a more controlled sound and feel, hot-swap versatility, and a dedicated volume knob for quick audio tweaks during work or play. The south-facing RGB is visually appealing and flexible via software for personalized lighting. What may fall short for some: if you’re strictly after an ultra-silent keyboard, or if you prefer a larger layout with more dedicated keys, the 75% form factor could feel a bit cramped for certain workflows.



Real-world use and example
Imagine gaming with a tight mouse setup, sipping through a long raid or fast FPS rounds. The AK820’s volume knob lets you mute or adjust game/audio on the fly without interrupting your keystrokes. The hot-swappable PCB means you can switch to different switches later to suit new preferences without replacing the whole board.

Considerations before buying
- If you prioritize a larger layout with full-height number pad, this 75% may not be ideal.
- Check compatibility with your OS and software for RGB customization, since features run through driver software.
- Remember that lighting and gasket damping add to the tactile experience but can also influence initial sound and feel depending on keycap and switch combination.
- Ensure you’re comfortable with a wired connection, wireless options aren’t mentioned here.
