Housing materials
The FJ400 and Gateron Ink Box Black differ significantly in their housing materials, leading to distinctive sound profiles that reflect their unique characteristics. The FJ400 utilizes a POM top housing, which is known for its ability to produce a pleasing and muted sound. POM's inherent qualities lend themselves to a deeper sound profile that is less sharp, making for a more subdued auditory experience during typing. In contrast, the Ink Box Black’s top housing employs a proprietary INK blend, which offers a strikingly higher-pitched sound that is both bright and clacky. This difference highlights how the material composition and design influence the auditory feedback one can expect from each switch.
The bottom housings of these switches further intensify their individual sound profiles. The FJ400 features a nylon bottom housing, recognized for its traditional and softer properties, which contributes to a fuller, rounder sound when typing. The softness of nylon helps absorb sound, resulting in a deeper experience that pairs well with its POM top. Meanwhile, the Ink Box Black also uses a proprietary INK blend for its bottom housing, echoing the characteristics found in its top. This material yields a pointed, high-pitched sound and results in pronounced clacks when bottoming out, distinguishing its auditory impact even more from the FJ400.
Despite the distinct sound profiles for the two switches, the impact of housing materials on the overall typing experience can lead to some similarities in results due to their compositional dynamics. The split between the top and bottom housings in both switches means that even with differing materials, the FJ400 and Ink Box Black can create engaging feedback during use. For instance, while the FJ400 delivers a more muted response due to its nylon bottom and POM top, the Ink Box Black's combination of INK blends may yield a more pronounced auditory experience. Nonetheless, players seeking unique feedback will find pleasure in both switches, as the qualities of their respective housings balance the auditory and tactile sensations experienced in each keystroke.
Weight
When comparing the HMX FJ400 linear switch to the Gateron Ink Box Black linear switch, we find distinct differences in their actuation and bottom out forces. The FJ400 has an actuation force of 50 grams, which is lighter than the Ink Box Black's 60 grams. This means that users who prefer a more effortless typing experience may find the FJ400 more suited for long typing sessions or gaming marathons. Additionally, the bottom out force of the FJ400 is 58 grams, whereas the Ink Box Black has a heavier bottom out force of 70 grams. The heftier actuation and bottom out forces of the Ink Box Black cater to those who enjoy a more substantial feel when typing, providing a firmer resistance that some users find satisfying. Overall, while both switches fall within the medium to medium-heavy range, the FJ400 offers a lighter option, making it the preferable choice for those who prioritize comfort in prolonged use, while the Ink Box Black serves those who desire a stronger push feel.
Travel distance
When comparing the travel distances of the HMX FJ400 linear switch and the Gateron Ink Box Black linear switch, we find that the FJ400 has a travel distance of 3.8 mm, while the Ink Box Black measures slightly less at 3.6 mm. This makes the FJ400 the longer option, providing more depth when pressed, which might appeal to users who enjoy a more substantial feel while typing or gaming. In contrast, the shorter travel distance of the Ink Box Black can offer quicker responsiveness, making it an excellent choice for gamers who prioritize speed. Although both switches fall within the realm of traditional distances, the FJ400's extra 0.2 mm can contribute to a more tactile experience. Thus, depending on personal preference, individuals may gravitate towards the switch that aligns with their typing style and response time needs.

Regarding feel, the FJ400's qualities are not explicitly defined here, so their comparative smoothness remains an unknown aspect. However, the Ink Box Black is known for its exceptional smoothness, described as silky and polished. This results in an effortless typing experience with minimized resistance, allowing for quick and precise keystrokes. The refined finish of the Ink Box Black enhances not only the tactile experience but also contributes to a satisfying overall functionality that can elevate your typing enjoyment.

Conclusion
To conclude, the decision between the HMX FJ400 and the Gateron Ink Box Black linear switches ultimately hinges on your personal preferences for tactile feedback and sound profile. If you prefer a medium actuation force and are looking for a balanced sound profile that fits well in a variety of typing or gaming scenarios, the FJ400 might be your best bet. Its sound is designed to be unassuming, making it suitable for quiet environments while still providing a satisfying typing experience. On the other hand, if you lean towards a heavier feel and crave a smooth, creamy typing experience paired with a distinctly clacky and high-pitched sound, the Ink Box Black will likely resonate with you more. Its silky and polished characteristics offer an exceptionally smooth feel, making it an attractive option for those who enjoy extended typing sessions or gaming marathons. Overall, consider how each switch aligns with your specific needs—whether it’s sound, feel, or the weight of the key press—and choose accordingly to enhance your mechanical keyboard experience.
