HMX FJ400 vs. Jwick Semi-Silent Linear
An in-depth look at the HMX FJ400 and the Jwick Semi-Silent Linear switches—which one is the best fit for you?
Overview
When it comes to choosing the perfect mechanical keyboard switch, the HMX FJ400 and the Jwick Semi-Silent Linear both offer unique tactile experiences tailored to different preferences. The FJ400, often celebrated for its harmonious sound profile and balanced typing feel, sits squarely in the middle of the HMX Film switch lineup, making it an appealing option for users who seek a dependable switch with moderate feedback and sound. In contrast, the Jwick Semi-Silent Linear stands out with its innovative design that boasts a whisper-quiet topping-out sound, combined with a delightful clacky bottom-out noise. This switch offers a silky smooth typing experience without feeling overly polished, and its nuanced classification as 'Subdued,' 'Neutral,' and 'Buttery' adds to its versatile charm. Ultimately, while both switches cater to linear switch enthusiasts, they serve different niches within that category. However, let's dive in a bit deeper beyond generalities so you can best decide on the switch that suits your typing style and needs.

Housing materials
The HMX FJ400 and the Jwick Semi-Silent Linear switches exhibit different acoustic characteristics due to their distinct top housing materials. The FJ400 utilizes a POM (Polyoxymethylene) top housing, which produces a sound profile that is deeper and relatively muted. This softness in the sound can be attributed to POM's properties, which favor a more closed-off acoustic environment, leading to a unique auditory experience. In contrast, the Semi-Silent Linear features a polycarbonate top housing, known for its stiffness which results in a sharper and higher-pitched sound profile. The clarity and resonance afforded by the polycarbonate material create a much crisper auditory feedback, making it ideal for users who prefer a more pronounced sound when typing. If aesthetic considerations matter, the translucence of the polycarbonate also offers visual benefits when paired with RGB lighting.
Both switches feature nylon as their bottom housing material, which contributes to a similar depth and fullness in their sound profiles. This commonality means that regardless of the differences in their top housings, typing on both switches elicits a deeper, rounder sound experience due to nylon’s sound-absorbing properties. The inherent softness of nylon mitigates the harsher elements that might be introduced by a harder plastic, enhancing the overall auditory experience. Thus, while the top housings diverge in acoustic outcomes, both switches achieve an enriched typing experience through their shared nylon bottoms.
The interaction of the housing materials plays a crucial role in the overall typing feel and sound. In the case of the FJ400, the POM top housing emphasizes a softer and more muted release sound, while the nylon bottom reinforces a fuller key-press sound. Conversely, the Semi-Silent Linear's combination of a polycarbonate top with a nylon bottom results in a pronounced key release sound that is crisper, while the nylon dampens the impact noise at the bottom. This split between the distinct top and bottom housing characteristics reinforces the importance of material selection in crafting the final sound signature of each switch. Consequently, users can choose between a deeper sound experience with the FJ400 or a more vibrant auditory presence with the Jwick, all while enjoying the foundational consistency that the nylon bottom housing provides.
Weight
When comparing the HMX FJ400 linear switch to the Jwick Semi-Silent Linear switch, there are distinct differences in their actuation and bottom out forces. The FJ400 features an actuation force of 50 grams, which offers a balanced typing experience, while the Semi-Silent Linear does not have a specified actuation force, making direct comparison difficult. However, the bottom out force of the FJ400 is 58 grams, which is again lower than the Semi-Silent Linear's bottom out force of 62 grams. This highlights that the Jwick switch is the heavier option overall, making it potentially less suitable for extended typing sessions for those who prefer lighter switches. Conversely, the HMX FJ400’s medium-force characteristics allow for a more approachable feel that can accommodate both longer usage and the preference for a stronger push, although that strength is not as pronounced as with the Jwick switch. Ultimately, if one seeks a lighter option for prolonged use, the FJ400 would be the preferred choice, while the heavier Semi-Silent Linear switch might appeal to those desiring a more substantial typing experience.
Travel distance
The HMX FJ400 linear switch and the Jwick Semi-Silent Linear linear switch have similar design intents, but they differ marginally in travel distance. The FJ400 features a travel distance of 3.8 mm, while the Semi-Silent Linear has a travel distance of 3.7 mm. In this comparison, the Semi-Silent Linear is the shorter option, offering a slightly quicker response which may appeal to gamers looking for rapid actuation. Conversely, the FJ400 provides a deeper feel, making it more suitable for users who prefer a more pronounced keypress sensation. While the difference in travel distance is minimal, it may still influence user preference depending on their typing or gaming style. For those who prioritize responsiveness, the Semi-Silent Linear could be the preferred choice, whereas individuals seeking a more substantial tactile experience might favor the FJ400 linear switch.

Typing experience
In terms of sound, the HMX FJ400 linear switch offers a balanced sound profile that sits comfortably between quieter and more pronounced options. It strikes a chord with users who prefer a moderate sound level, making it versatile enough for both home and office use. On the other hand, the Jwick Semi-Silent Linear switch provides a unique audio experience with its semi-silent designation. While it features a whisper-quiet topping-out sound that contributes to a more subdued typing experience, it still maintains a clacky bottom-out sound. This combination allows users to enjoy a typing experience that is less disruptive, yet still engagingly audible when bottoming out.
When it comes to feel, the FJ400 is known for its smoothness, hitting a comfortable middle ground that allows for easy and enjoyable typing without being overly soft or too resistant. The Semi-Silent Linear switch, however, showcases a multi-faceted feel with descriptors like mild, snappy, buttery, and polished. The mild quality ensures an approachable typing experience while still maintaining responsiveness, and users will appreciate the buttery and polished sensations that deliver both a smooth keystroke and a refined finish. This creates a typing experience that is fluid and almost effortless.
Overall, both the HMX FJ400 and Jwick Semi-Silent Linear switches present excellent options for users seeking enjoyable linear switch experiences. While the FJ400 provides a balanced sound with a straightforward feel, the Semi-Silent Linear stands out with its innovative sound and multi-dimensional feel qualities. Despite their differences, both types of switches will likely offer satisfactory results, particularly for those who appreciate smooth and quiet typing sessions.
Conclusion
To wrap up, the decision between the HMX FJ400 and the Jwick Semi-Silent Linear linear switches ultimately depends on your personal preferences and typing environment. If you gravitate towards a balanced typing experience with a moderate sound profile, where you receive consistent feedback without excessive noise, the FJ400 may be your ideal choice. Its medium bottom-out force of 58 grams offers a satisfying engagement that's well-suited for both casual typing and extended gaming sessions. On the other hand, if you value a quieter experience without sacrificing responsiveness, the Jwick Semi-Silent Linear could be the better option. Its slightly stronger bottom-out force of 62 grams delivers a silky smooth feel with a unique sound profile—where the topping-out noise is subdued but the bottom-out remains clacky, allowing for an engaging tactile experience. Therefore, consider your surroundings, whether you need a more discreet option or prefer the balanced characteristics of the FJ400, and choose the switch that aligns best with your typing style and auditory preferences.
