Selecting a mechanical keyboard involves balancing form factor, functionality, and material properties. Models with a 75% layout have established themselves as a popular category, offering a balance between the compactness of a tenkeyless (TKL) keyboard and the functionality of a full-size one. They retain the dedicated function row and arrow keys while omitting the number pad, resulting in significant desk space savings. The AJAZZ AK820 Mechanical Keyboard is a prime example of this form factor, further integrating features like a dedicated volume knob and a gasket-mount design. This article analyses the model's technical specifications and practical utility.
The decision to purchase a keyboard should be based on objective criteria. The following technical aspects are relevant when evaluating models like the AJAZZ AK820.
A 75% layout typically includes 81 to 84 keys. Unlike more compact 60% or 65% layouts, the F-keys (F1-F12) and arrow keys are retained as separate, dedicated keys. This is advantageous for many users, especially in productivity tasks and gaming, as it eliminates the need for secondary layers (using the Fn key) for these fundamental functions. The AJAZZ AK820 leverages this form factor to deliver high functionality within a smaller footprint.
The mounting style describes how the printed circuit board (PCB) and the plate, which holds the switches, are secured within the case. A gasket-mount design uses gasket materials (typically silicone or Poron foam) between the plate and the case. This isolates typing vibrations from the case, leading to two primary effects:
A hot-swap keyboard allows for the replacement of mechanical switches without any soldering. The PCB is equipped with special sockets that allow 3-pin or 5-pin switches to be easily plugged in. The advantages are:
The keycaps are the user's primary point of contact. The material significantly influences the feel and durability.
The AK820 is shipped with PBT keycaps, which indicates greater durability for the surface texture and legends.
As a wired keyboard, the AK820 relies on a USB-C connection. This ensures a stable and low-latency signal transmission, a critical factor, especially for competitive gaming. Another standout feature is the integrated volume knob, crafted from CNC-milled metal, which allows for quick and precise system volume adjustments without software intervention.
Based on the criteria mentioned above, we present two variants of the AJAZZ AK820.
Why We Recommend This Product This model combines the gasket-mount structure with clicky blue switches and an ice-blue backlight. The translucent PBT keycaps are designed to accentuate the lighting while offering high durability. The combination of tactile and auditory feedback from the blue switches is aimed at users who prefer a distinct actuation feel.
Pros
Who It's For This model is suitable for users seeking a wired keyboard with pronounced tactile and auditory feedback. It is an option for heavy typists and gamers who appreciate the characteristic "click" of mechanical switches and value a striking lighting aesthetic. Please note the QWERTY US layout.
Why We Recommend This Product This variant of the AK820 is equipped with linear yellow switches, which provide smooth and resistance-free key travel. Combined with the gasket-mount structure and multi-layer dampening, this model aims for an exceptionally quiet and fluid typing experience. The RGB backlighting with south-facing LEDs ensures vibrant and uniform illumination.
Pros
Who It's For This configuration is ideal for PC gamers and office users who prefer a fast, quiet, and responsive gaming keyboard. The linear switches are well-suited for rapid key sequences, while the dampening is beneficial in environments where noise minimisation is a priority. Here too, the QWERTY US layout should be taken into account.
While a functional keyboard is a central element of any setup, the overall atmosphere of the work or gaming area is also influenced by other components, such as lighting. For users looking to further optimise their station, exploring options for specialised ambient lighting can be a logical next step. A suitable red lamp, for example, can help create a specific mood or reduce eye strain at night.
What is the advantage of a 75% keyboard like the AJAZZ AK820? The main advantage lies in the layout's efficiency. It saves considerable desk space compared to a full-size keyboard, allowing more room for mouse movement. At the same time, it retains important dedicated keys like the arrow and function keys, which are often only accessible via key combinations on even smaller 60% or 65% layouts.
Is the AJAZZ AK820 suitable for gaming? Yes, its technical features support gaming use. The wired USB-C connection ensures low input latency. Depending on the chosen variant, the linear switches offer fast actuation for competitive games, while the hot-swap capability allows users to adapt the switches to their personal preferences.
What does "hot-swap" mean on a mechanical keyboard? "Hot-swap" means that the keyboard's mechanical switches can be replaced without soldering. The printed circuit board (PCB) has sockets that allow compatible switches to be simply pulled out and new ones inserted. This facilitates personalising the typing feel, repairing individual keys, and experimenting with different switch types.
