Housing materials
The HMX FJ400 and KTT Kang White showcase a distinct contrast in the materials used for their top housings, with the FJ400 utilizing POM and the Kang White employing polycarbonate. POM, or polyoxymethylene, is known for producing a unique sound profile that is deeper and more muted, which contributes to an overall warmer typing experience. This softer sound can be appealing for users who prefer a less harsh auditory feedback while typing. In contrast, the Kang White's polycarbonate top housing delivers a sharper, higher-pitched sound profile. The inherent stiffness of polycarbonate enhances its resonance capability, resulting in a crisper auditory experience that may be more attractive to users who enjoy a bright and lively sound. The translucency of polycarbonate also allows for better RGB lighting effects, adding a vibrant aesthetic element that can enhance the visual appeal of mechanical keyboards.
When we turn our attention to the bottom housings of both switches, we find a commonality: both the FJ400 and the Kang White utilize nylon as their bottom housing material. Nylon is a classic choice in switch housing, known for its ability to create a deeper and fuller sound experience. This trait remains consistent across both models, emphasizing that while the top housings vary greatly, the bottom housings share significant sonic characteristics. This shared material allows for a similar auditory outcome regarding the fullness of sound produced during typing, especially when the switch bottom-out occurs. The nylon provides that classic, muted, and rounded sound profile, which many users appreciate for its comfort and subtlety.
In summary, the differences in top housing materials between the HMX FJ400 and the KTT Kang White lead to unique sound profiles that cater to different user preferences. While the POM top housing creates a deeper and more muted sound, the polycarbonate top housing yields a brighter and crisper audio feedback. Nevertheless, both switches share the nylon bottom housing, which ensures a consistent and fuller sound experience during typing. As such, despite their differences in upper housings, both switches can provide a satisfying typing experience for users seeking that classic nylon sound combined with either a muted or sharp auditory character thanks to the unique materials chosen for the tops.
Weight
When comparing the HMX FJ400 linear switch and the KTT Kang White linear switch, both exhibit a medium bottom out force of 58 grams, indicating that they require the same amount of force to press fully down. However, the actuation forces differ, with the FJ400 requiring 50 grams to register a keystroke, while the Kang White necessitates only 45 grams. This means that the KTT Kang White is the lighter option, making it potentially more suitable for users who prefer a less strenuous typing experience, particularly during extended use like long work hours or gaming sessions. Conversely, the HMX FJ400, with its slightly higher actuation force, offers a more substantial feel, catering to those who favor a firmer push and tactile feedback while typing.
Travel distance
The HMX FJ400 linear switch features a travel distance of 3.8 mm, whereas the KTT Kang White linear switch has a slightly longer travel distance of 4.0 mm. This makes the FJ400 the shorter switch, which may appeal to gamers or users who prefer faster responsiveness in their keystrokes. On the other hand, the Kang White, with its conventional travel distance, provides a more traditional feel that some users might favor for its more substantial depth. For those who appreciate a bit more travel and feedback when typing, the longer distance of the Kang White may be ideal. Thus, the choice between these two switches ultimately hinges on personal preference for either a quicker response or a more tactile experience.
