HMX FJ400 vs. Gateron Silent Ink Black
An in-depth look at the HMX FJ400 and the Gateron Silent Ink Black switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, the choice often boils down to personal preferences in feel and acoustics. The HMX FJ400 is a linear switch that strikes a balance between sound and performance, making it a solid choice for those who appreciate an even typing experience without being overly noisy. Its middle-ground position in the HMX Film switch lineup appeals to gamers and typists alike, offering a satisfying stroke on each key press. In contrast, the Gateron Silent Ink Black caters to users who prioritize a quieter environment, featuring a silenced design that minimizes audio feedback while maintaining a smooth typing experience. With its cushy, pillow-like bottom-out feel, the Silent Ink Black is perfect for offices or shared spaces where noise levels are a concern. Both switches have their unique strengths—whether you lean toward the balanced profile of the FJ400 or the muted sophistication of the Silent Ink Black, each can enhance your typing experience differently. 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 Silent Ink Black switches, distinct differences emerge in the type of materials used and the resultant sound profiles they produce. The FJ400 switch features a POM (Polyoxymethylene) top housing and a nylon bottom housing. POM is known for creating a deeper, more muted sound due to its dense and smooth characteristics, which contributes to a satisfying typing experience. Conversely, the Gateron Silent Ink Black employs a proprietary INK blend for both the top and bottom housings. This unique material is designed to provide a higher-pitched, clackier sound profile, which distinguishes itself from the muted tones of the FJ400.
The contrasting properties of the materials play a significant role in the acoustics of both switches. The nylon bottom housing of the FJ400 absorbs sound more effectively due to its softer composition, producing a fuller and rounder sound profile, while the POM top housing's smooth nature adds a deeper resonance. The Silent Ink Black, however, performs differently; its proprietary INK blend is crafted to create a thinner and sharper sound, giving it a pointed character. As a result, the upper and lower housing materials influence not just the sound but also the tactile feedback experienced during use. This difference highlights the nuanced ways in which switch materials affect overall typing experiences.
Despite the clear distinctions, there is a possibility of achieving similar sonic outcomes depending on user preference. While the FJ400’s combination of POM and nylon yields a deeper and rounder auditory experience, users seeking sharper sound profiles may find the Silent Ink Black appealing with its pronounced clacky tone. If someone finds joy in using either switch, they could effectively simulate the desired sound experience of the other by considering their typing habits. Ultimately, while the FJ400 and Silent Ink Black exemplify different qualities in housing materials, similarities will manifest in users' typing styles and preferences, leading to rewarding outcomes regardless of choice.
Weight
When comparing the HMX FJ400 linear switch and the Gateron Silent Ink Black linear switch, notable differences emerge in their actuation and bottom out forces. The FJ400 has a lighter actuation force of 50 grams and a bottom out force of 58 grams, making it suitable for users who prefer a more effortless typing experience, ideal for extended periods of use. In contrast, the Silent Ink Black switch requires a stronger actuation force of 60 grams and has a bottom out force of 70 grams, catering to those who seek a more substantial feel while typing. As a result, the Silent Ink Black is the heavier option, appealing to individuals who appreciate a stronger tactile response. Ultimately, those who opt for the FJ400 will benefit from a lighter touch, while users who choose the Silent Ink Black will enjoy a firmer keystroke.
Travel distance
When comparing the travel distances of the HMX FJ400 linear switch and the Gateron Silent Ink Black linear switch, we find some notable differences. The FJ400 has a travel distance of 3.8 mm, making it the shorter option, while the Silent Ink Black has a slightly longer travel distance of 4.0 mm. This means that the Silent Ink Black will provide a more traditional and deeper pressing experience, which some users may find more satisfying compared to the shorter, quicker response of the FJ400. Gamers seeking quicker actuation might prefer the FJ400 for its reduced travel distance, but for those who enjoy a more substantial feel, the Silent Ink Black would be the better choice. In summary, while both switches cater to different preferences, the FJ400 offers a quicker response with its shorter travel distance, whereas the Silent Ink Black provides a more pronounced keypress experience.

Typing experience
When it comes to sound, the HMX FJ400 linear switch offers a balanced sound profile that is neither excessively loud nor overly quiet, making it suitable for various environments. In contrast, the Gateron Silent Ink Black is designed specifically for minimal noise, producing a muted sound that greatly reduces the typical audio feedback found in standard mechanical switches. This advantage makes the Silent Ink Black ideal for quiet workspaces where silence is valued. However, it is essential to remember that sound perception can be influenced by other factors, such as the keyboard build and keycap material.
In terms of feel, the FJ400 is positioned as a middle ground within the HMX Film switch lineup, which typically suggests a smooth but not overly refined typing experience. On the other hand, the Silent Ink Black switch excels with its silky and polished characteristics, providing an exceptionally smooth and refined feel that minimizes resistance during key presses. This creates a luxurious typing experience that is both comfortable and satisfying, making the Silent Ink Black a preferred choice for users who prioritize a plush tactile sensation.
Overall, while both switches have their unique attributes, the HMX FJ400 balances sound and feel for a versatile experience, whereas the Gateron Silent Ink Black primarily focuses on providing a muted sound and an exceptionally smooth feel. Choosing between them will largely depend on personal preferences—whether you lean towards a balanced experience or a quieter and smoother typing environment. If the qualities are similar, both options will deliver pleasing typing experiences but with distinct characteristics tailored to specific needs.
Conclusion
To conclude, when choosing between the HMX FJ400 linear switch and the Gateron Silent Ink Black linear switch, your environment and typing preferences are key considerations. If you’re looking for a balanced sound profile and a moderate feedback feel, the FJ400 is likely your best bet. With its 58-gram bottom-out force, it provides a nice middle ground that suits a range of typing styles and is ideal for casual use in environments where some noise is acceptable. On the other hand, if you require a quieter typing experience, especially in shared spaces or during late-night sessions, the Silent Ink Black’s higher 70-gram bottom-out force and muted sound will serve you well. This switch is designed for those who prioritize a silky, polished feel combined with minimal noise, making it fantastic for focused work or gaming without disturbing others. Ultimately, your choice should align with your sound preferences and tactile experience, leading you to either a well-rounded feel with the FJ400 or a luxurious, quiet experience with the Silent Ink Black.
