HMX FJ400 vs. Akko Penguin
An in-depth look at the HMX FJ400 and the Akko Penguin switches—which one is the best fit for you?
Overview
When it comes to choosing the right mechanical keyboard switches, the decision often comes down to personal preference and intended use. The HMX FJ400, categorized as a linear switch, is celebrated for its balanced sound profile, making it an excellent choice for those seeking a smooth and uninterrupted typing experience. Its linear nature ensures consistent key presses without tactile feedback, which many users appreciate for rapid key activation, particularly in gaming scenarios. On the other hand, the Akko Penguin switches introduce a tactile element to the mix, designed for environments where noise control is paramount. These switches feature a rounded tactile bump, delivering satisfying yet subtle feedback with each press, while their muted design caters to the needs of professionals looking to minimize disruption in shared spaces. With a medium weight that balances responsiveness and comfort, the Penguins are fantastic for extended typing sessions. Both switches cater to different needs and preferences: the FJ400 for those who value speed and smoothness, and the Penguin for those who appreciate tactile feedback without the clatter. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The HMX FJ400 and the Akko Penguin exhibit differing top housing materials that significantly influence their sound profiles during usage. The FJ400 features a POM top housing, known for producing an incredibly pleasing and unique sound with deeper characteristics, while having a more muted tonality. In contrast, the Penguin utilizes a nylon top housing, which also delivers a deeper and fuller sound profile, albeit with a slightly more rounded quality due to the material's inherent properties. This difference in materials creates distinct sound experiences when typing, where users of the FJ400 might notice a sharper and less resonant sound compared to the softer, more enveloping qualities of the Penguin's nylon top.
On the other hand, both the HMX FJ400 and the Akko Penguin share nylon as their bottom housing material. This consistency in the bottom housing means that both switches will elicit a deeper and fuller sound profile as a result of the nylon's softer plastic characteristics. The shared quality of nylon allows for a similar bottoming-out experience, where the switches can facilitate a duller and rounder sound with satisfying thock-like feedback. Since both switches utilize nylon in this aspect, users can expect a comparable response when bottoming out, despite the differences up top.
In summary, while the HMX FJ400 and Akko Penguin have contrasting top housings—which affects their sound when releasing the key—their matching nylon bottom housings ensure there is a harmonious quality to their overall function. Therefore, while users may notice distinct sound profiles from the top housing on each keyboard, the shared bottom housing material allows them to achieve similar results in terms of the overall typing feel and sound during key presses. This combination of materials highlights how variations in switch design can create unique typing experiences while also providing familiar comfort and sound due to shared components.
Weight
When comparing the actuation and bottom out forces of the HMX FJ400 linear switch and the Akko Penguin tactile switch, there are notable differences in their actuation forces, while their bottom out forces are somewhat similar. The FJ400 requires an actuation force of 50 grams, which provides users with a heavier typing experience, while the Penguin is lighter, at an actuation force of 43 grams. This difference makes the FJ400 more suitable for those who prefer a substantial feel while typing or gaming, as it can offer a more immersive experience. In terms of bottom out forces, the FJ400 bottoms out at 58 grams, whereas the Penguin reaches 60 grams, indicating that both switches require a similar amount of force when pressed fully down, with the Penguin being slightly heavier at bottom out. Overall, if you're seeking a lighter and potentially more comfortable typing experience over extended periods, the Akko Penguin is the better choice, while the HMX FJ400 may appeal more to those who enjoy a firmer keystroke.
Travel distance
The HMX FJ400 linear switch has a travel distance of 3.8 mm, while the Akko Penguin tactile switch features a slightly shorter travel distance of 3.3 mm. This indicates that the FJ400, with its 3.8 mm travel, offers a more substantial key press, which some users might find more satisfying and easier for typing. On the other hand, the Penguin's shorter 3.3 mm travel distance can cater to gamers or those who prefer quicker actuations, leading to faster response times. Therefore, if you prioritize a more tactile and deeper feel, the FJ400 would be the better choice, while the Akko Penguin would cater well to those seeking a snappier, more streamlined experience. Ultimately, these travel distances provide clear distinctions based on user preferences, with the FJ400 being the longer option and the Penguin the shorter.

Typing experience
When it comes to sound, the HMX FJ400 switch offers a balanced sound profile that provides an agreeable auditory experience. While specific details about its sound characteristics are absent, the neutral aspect suggests it's suitable for a variety of environments. On the other hand, the Akko Penguin switch is designed to minimize sound, making it particularly advantageous for office settings. It is described as muted, producing a softer sound compared to traditional mechanical switches, which would be more clacky and attention-grabbing. Given these qualities, someone using the FJ400 might enjoy a more versatile sound experience, while the Penguin will cater to those needing a quieter operation.
In terms of feel, the HMX FJ400 switch lacks specific descriptors, making it difficult to assess its overall typing experience. In contrast, the Akko Penguin switch is characterized by a polished finish that enhances smoothness and reduces friction, resulting in a sleek typing experience. Its mild and feathery nature ensures that it is gentle on the fingers, promoting comfort, especially during extended use. With such refined qualities, the Penguin provides a tactile feedback that is both subtle and accessible, ideal for users looking for a balanced yet rewarding typing sensation.
In conclusion, while the HMX FJ400 switch presents a more neutral auditory experience possibly suitable for all environments, the Akko Penguin excels in sound dampening, making it ideal for quiet settings. The absence of descriptive feel characteristics for the FJ400 leaves some uncertainty about its user experience, while the Penguin clearly offers a refined and gentle typing sensation. Ultimately, individuals seeking a versatile sound profile may gravitate towards the FJ400, whereas those prioritizing a quieter and comfortable typing journey will find the Akko Penguin to be a superb choice.
Conclusion
To conclude, your choice between the HMX FJ400 linear switch and the Akko Penguin tactile switch ultimately depends on your specific typing needs and environmental considerations. If you prefer a smooth, uninterrupted keystroke and value a more balanced sound profile, the FJ400 is an excellent option—its medium bottom-out force offers a satisfying yet not overly forceful typing experience, making it suitable for both casual and focused work. On the other hand, if you're in a quiet office setting or share your workspace with others, the Akko Penguin switches are designed for noise minimization while still providing tactile feedback, thanks to their muted sound and rounded bump. Their polished feel ensures a smooth and pleasant experience, making them ideal for long typing sessions without the risk of disturbing those around you. In essence, choose the FJ400 for a reliable linear performance and the Penguins when comfort and discretion are your priorities.
