HMX FJ400 vs. Gateron Zero Degree 0°
An in-depth look at the HMX FJ400 and the Gateron Zero Degree 0° switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, the HMX FJ400 and the Gateron Zero Degree 0° linear switches each bring distinct characteristics to the table, catering to different user preferences. The FJ400 strikes a harmonious balance within the HMX Film switch lineup, offering a satisfying keystroke with an appealing sound profile that blends performance and auditory pleasure. In contrast, the Gateron Zero Degree 0° takes the notion of silent typing to new heights; its innovative self-padding design paired with a dual-rail structure ensures a smooth and stable experience while absorbing excess sound, making it an excellent choice for quieter work environments or late-night gaming sessions. Both switches offer a linear feel, promoting seamless key presses without tactile bumps, but they differ vastly in auditory feedback and construction. Ultimately, your choice will depend on whether you prioritize a balanced acoustic experience with the FJ400 or the ultra-quiet, plush strokes of the Zero Degree 0°. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
When comparing the housing materials of the HMX FJ400 and the Gateron Zero Degree 0°, notable differences in sound profiles arise from their respective top housings. The FJ400 incorporates a POM (Polyoxymethylene) top housing, which is known for producing a deeper, muted sound characteristic. This material offers a unique auditory experience that differs significantly from the sharp and crisp tones generated by the Zero Degree 0°'s polycarbonate top housing. The polycarbonate material's stiffness enhances the resonance, resulting in a brighter sound profile. Aesthetically, the translucency of the polycarbonate also allows for better diffusion of RGB lighting, making it a popular choice for backlit keyboards.
In terms of bottom housing, both the FJ400 and Zero Degree 0° utilize nylon, a classic choice known for its sound-dampening qualities. The use of nylon in both models ensures a deeper and fuller sound profile upon keystroke, as this softer plastic absorbs sound more effectively than its harder counterparts. This similarity in bottom housing suggests that while the top housings contribute distinct sound profiles, the nylon bottom housing will consistently deliver a richer sound experience for both switches. Therefore, regardless of the differences in the top materials, the shared nylon bottom will provide a foundational consistency in auditory feedback.
The interaction between top and bottom housing materials ultimately indicates a critical turning point for the switches’ performance. While the FJ400's POM top contributes to a more muted sound, the Zero Degree 0°'s polycarbonate enhances brightness and clarity. Consequently, the overall sound experience is dictated by the interplay of these materials. When typing, users will sense the nylon bottom's fuller sound regardless of the top housing differences, which impacts the bottom-out sound and feel. Thus, even though each switch offers a unique blend of housing materials, their similar bottom housing ensures that users will encounter a satisfying auditory experience, albeit with distinct variations in sound profile attributable to the different top housing materials.
Weight
The HMX FJ400 linear switch and the Gateron Zero Degree 0° linear switch present an interesting contrast in their actuation forces and bottom out forces. The FJ400 features an actuation force of 50 grams, requiring a moderate amount of pressure to register a keystroke, which is beneficial for those who prefer a balanced typing experience. In comparison, the Zero Degree 0° has a lighter actuation force of 45 grams, making it easier to press and potentially more suitable for prolonged typing sessions or gaming marathons where fatigue could be a concern. However, the bottom out force for the Zero Degree switch is unknown, leaving a gap in the comparison. The FJ400's bottom out force is 58 grams, indicating a firmer feel when keys are fully pressed, which may appeal to users who prefer a more substantial typing experience. Overall, the FJ400 is the heavier option, while the Zero Degree is lighter and could cater to users seeking less resistance during use.
Travel distance
When comparing the travel distances of the HMX FJ400 linear switch and the Gateron Zero Degree 0° linear switch, there is a notable difference. The FJ400 has a travel distance of 3.8 mm, making it the longer option, while the Zero Degree 0° features a shorter travel distance of 3.6 mm. For gamers seeking faster response times, the shorter travel distance of the Zero Degree 0° may be more appealing. However, those who prefer a deeper keypress and a more pronounced tactile feedback might opt for the FJ400 due to its longer travel distance, which can provide a more satisfying feel during use. Ultimately, the choice between these two switches depends on individual preferences regarding responsiveness and depth in keypress experience.

Typing experience
The HMX FJ400 linear switch is known for its balanced sound profile, falling in the middle ground of the HMX Film switch lineup. While it may not be the most silent option available, it produces a pleasant acoustic experience that is neither overly loud nor too muted. On the other hand, the Gateron Zero Degree 0° linear switch sets itself apart with its innovative self-padding design and dual-rail structure, which significantly dampens sound. This results in a near-silent typing experience that is particularly appealing for those who work in quieter environments or who dislike the audible feedback of traditional switches. Both switches' sound characteristics can also be influenced by the choice of keyboard and keycaps, but the Zero Degree is designed specifically for minimizing noise.
When it comes to feel, the FJ400 delivers a smooth typing experience that strikes a balance between responsiveness and softness, making it suitable for extended typing sessions without causing fatigue. Conversely, the Gateron Zero Degree 0° linear switch offers a remarkably soft and elastic feel due to its unique padding, which absorbs impact and allows for a fluid keystroke. This results in an exceptionally smooth and stable typing experience that promotes comfort, particularly for users who prioritize a silent and gentle touch when typing.
In conclusion, while the HMX FJ400 linear switch offers a balanced sound profile and a smooth feel, the Gateron Zero Degree 0° linear switch excels in sound dampening and provides an exceptionally soft typing experience. Both switches have their unique qualities, and depending on personal preference—whether one values sound or feel more—users can expect a satisfying typing experience from either option. For those who prioritize a quieter setup, the Zero Degree is particularly appealing, while the FJ400 offers a more traditional sound feel but remains comfortable for long usage.
Conclusion
To conclude, your choice between the HMX FJ400 linear switch and the Gateron Zero Degree 0° linear switch should be driven by your personal preferences and typing environment. If you're seeking a switch that strikes a balance between feel and sound, the FJ400 is a solid option, as it has a medium bottom-out force of 58 grams and offers a balanced sound profile. This makes it suitable for a variety of typing tasks, whether you're gaming or typing up documents. On the other hand, if you value a quieter typing experience and prioritize smoothness and stability, the Gateron Zero Degree 0° is an excellent choice. Its unique self-padding design effectively absorbs sound, making it perfect for shared spaces or for those who simply enjoy a discreet typing experience. Ultimately, consider your typing style and environment: go for the FJ400 for a versatile, balanced keyboard feel or choose the Zero Degree 0° for unparalleled silence and smoothness.
