Ajazz AK820 75% Hot Swappable Mechanical Keyboard with Volume Knob
Product description
What it is
The Ajazz AK820 is a compact 75% mechanical keyboard designed to save desktop space while keeping essential function keys within easy reach. It features a dedicated volume knob, a gasket-mounted construction for a solid, cushioned typing feel, and a hot-swappable PCB that supports both 3-pin and 5-pin switches. The board ships with pre-lubed linear switches and premium PBT keycaps, plus south-facing RGB for vibrant, consistent backlighting.
How it stands out

On paper, the AK820 blends several sought-after traits in a single package: a relatively small footprint (75% layout with 82-key footprint), a metal volume control knob for quick audio adjustments, and a gasket mount that aims to reduce hollow or rattly sounds. The hot-swap capability means you can experiment with different switch types without soldering, and the south-facing RGB LEDs favor a more even lighting on the key legends. The inclusion of Mac and Windows compatibility broadens its appeal for mixed setups.
What’s good about it
- Space-saving design without sacrificing function keys, helping you maintain more mouse room.
- Detachable USB-C wired connection promises a stable, low-latency link for gaming and work.
- Gasket-mounted build plus Poron cotton and high-density foam aim to deliver a solid, “thocky” typing vibe.
- Pre-lubed linear switches should feel smooth and quiet out of the box, with the option to customize further via hot-swap.
- Premium PBT keycaps resist oil buildup and keep legends legible longer.



What could be better
- The “thocky” sound profile is a matter of preference, if you prefer a crisper or louder click, you might want to swap switches or adjust the foam layers.
- As a 75% layout, the form factor isn’t ideal for everyone—if you rely heavily on a full-size keyboard, there will be a learning curve.
- Software-driven lighting effects require driver software, which adds a step for customization and may feel optional for casual users.
Who it’s for

- Gamers and productivity users who want a compact, clean desk setup without sacrificing function keys.
- People who value a quiet, cushioned typing experience and a solid, premium-feel chassis.
- Users who enjoy DIY tweaks and want the flexibility of hot-swappable switches.
Who it isn’t ideal for
- If you strictly prefer a full-size or 100% keyboard with a larger key array, this won’t replace your preferred layout.
- If you don’t care for a volume knob or south-facing RGB, some of the distinctive features may feel extraneous.
- Those who don’t plan to tinker with switches or keycaps might not maximize the potential of the hot-swap capability.



When it makes sense to buy
- You need more desk space but still want a capable gaming keyboard with a premium feel.
- You value a plugging-in-and-going experience with a stable wired connection and a ready-to-go backlit layout.
- You enjoy customizing lighting and switch feel, and you’re curious about a gasket-mount platform.
When to hold off

- If you’re shopping for a pure, no-frills typing experience, a non-gasket or non-hot-swappable board might be simpler and cheaper.
- If you require a very specific switch type or layout not supported by hot-swapping, you may want to consider alternatives.
What to check before buying
- Confirm the switches you’ll be using are compatible with the hot-swap PCB (3-pin or 5-pin).
- If possible, test the feel of the gasket-mount typing in person to ensure the sound/feel matches your preference.
- Consider the surface where you’ll place the keyboard, the weight and the metal volume knob add stability but may impact portability.
- Review your lighting preferences: 20 default modes plus driver-based customization are available, but setup time may vary.



Practical usage example
Imagine a late-night gaming session where you need audio on the fly. A quick twist of the metal volume knob mutes or adjusts your game soundtrack without leaving the keyboard area. The compact footprint keeps your mouse arena wide, and the creamy, controlled keystrokes from the pre-lubed linear switches help you type with confidence during long raids or coding sprints.
FAQ (based on available details)
- Q: Is the keyboard truly hot-swappable for both 3-pin and 5-pin switches? A: The PCB supports both 3-pin and 5-pin switches, enabling easy switch swaps.
- Q: Does it work with both Mac and Windows? A: Yes, it is described as widely compatible with Mac and Windows PCs.
- Q: What is the purpose of the gasket mount? A: The gasket mount, combined with layered foam and Poron, aims to reduce hollow typing noises and deliver a solid, thocky feel.
Final decision
Is it worth it? Worth considering if you want a compact, well-rounded gaming keyboard with customization options and a tactile, cushioned typing experience, plus a handy volume knob. It may not be ideal if you need a full-size layout or if you don’t plan to explore switch customization.
