Housing materials
The housing materials of the HMX FJ400 and TTC Gold Red switches present a distinct contrast in their acoustic profiles, primarily due to their different top housings. The FJ400 features a top housing made of POM, which is known for producing a deeper and more muted sound profile. This material enhances the overall sound quality by delivering rich, rounded notes that tend to soften the sound pangs during typing. In contrast, the TTC Gold Red utilizes a polycarbonate top housing that results in a sharper, higher-pitched sound. The inherent stiffness of polycarbonate contributes to a clearer and more resonant tone, making the resulting auditory feedback more pronounced and crisp. For users who relish RGB lighting, the translucency of the polycarbonate also offers a visually appealing element, enhancing the aesthetic appeal of the keyboard.
When it comes to the bottom housing, both the FJ400 and Gold Red share the classic nylon material, which shapes their auditory experience in a similar way. Nylon is revered for its ability to create a fuller, deeper sound by effectively absorbing vibrations, resulting in a softer and rounder acoustic profile. Despite the contrasting top housings, both switches benefit from this nylon composition at the bottom, ensuring that the overall sound output retains a degree of depth and fullness that may appeal to typists desiring a more subdued, intimate typing experience. Therefore, even though the top materials differ significantly, the shared nylon bottom housing helps unify the switches’ performance in terms of sound quality.
Overall, the combination of a POM top housing in the FJ400 and a polycarbonate top housing in the Gold Red contributes to a contrasting sound profile, while both switches’ nylon bottom housings ensure they provide comparable characteristics in depth and warmth. Users can expect a richer sound from the FJ400 while experiencing sharper feedback from the Gold Red, yet both share a commonality that balances their unique traits. Consequently, whether one prefers the muted richness of the FJ400 or the crispness of the Gold Red, each switch offers distinct auditory experiences while retaining depth through their shared bottom housing material.
Weight
The HMX FJ400 and TTC Gold Red linear switches present distinct characteristics in terms of actuation and bottom out forces, catering to different preferences among users. The FJ400 features an actuation force of 50 grams and a bottom out force of 58 grams, categorizing it as a medium-force switch that offers a more substantial typing experience, ideal for those who favor a heavier feel when typing or gaming. In contrast, the Gold Red switch has a lighter actuation force of 43 grams and a bottom out force of 50 grams, making it more suitable for longer typing sessions or gaming marathons as it requires less effort to press down. Therefore, those who prefer a lighter switch for comfort and extended use would lean towards the Gold Red, while users seeking a firmer push would find the FJ400 more appealing. The difference in both actuation and bottom out forces further emphasizes the suitability of each switch for varying typing styles and preferences.
Travel distance
When comparing the travel distance of the HMX FJ400 linear switch and the TTC Gold Red linear switch, we find that the FJ400 features a travel distance of 3.8 mm, while the Gold Red has a slightly longer distance of 4 mm. This means that users who prefer a more responsive feel may lean towards the FJ400 due to its shorter travel distance, which can facilitate quicker key presses—an aspect particularly favored by gamers. Conversely, those who appreciate a more substantial depth in their keystrokes might opt for the Gold Red, as its longer travel distance offers a more pronounced tactile experience. Hence, in this comparison, the FJ400 provides a shorter travel distance at 3.8 mm, making it the better choice for speed, whereas the TTC Gold Red, with its longer 4 mm travel distance, caters to those seeking a more traditional and deeper typing experience.

Typing experience
When it comes to sound, the HMX FJ400 linear switch offers a balanced sound profile that makes it a versatile choice for various settings, though specific characteristics are not detailed. In contrast, the TTC Gold Red switches are noted for their thocky, low-pitched audio feedback, producing a deep and rich sound reminiscent of a satisfying thud or knock when keys are pressed and released. The Gold Red’s sound profile is neutral, making it suitable for both homes and workplaces and offering a modest touch of personality without being overly intrusive. Therefore, while the FJ400 provides a balanced auditory experience that fits into multiple environments, the Gold Red offers a more distinctive and sonorous character.
In terms of feel, the FJ400’s characteristics are not specified, making it difficult to compare directly; however, the TTC Gold Red is celebrated for its mild, silky, and polished typing experience. This means the Gold Red offers gentle keypress resistance, resulting in an exceptionally smooth and refined feel, making it approachable for users regardless of their typing experience. The subtle resistance ensures a light typing experience while avoiding any jarring sensations, further enhancing comfort during extended use. The lack of details on the FJ400 leaves its tactile qualities open to interpretation; however, the Gold Red clearly prioritizes a smooth and comfortable feel.
In summary, while the HMX FJ400 and TTC Gold Red linear switches cater to distinct user preferences, the FJ400’s balanced sound profile could appeal to those seeking versatility, whereas the Gold Red stands out for its rich auditory feedback and exceptionally smooth typing feel. Although the FJ400’s specifics remain unclarified, users can expect a satisfying experience with either choice, especially if a smooth typing action is a priority. Ultimately, the choice may come down to individual tastes, particularly concerning sound characteristics and typing feel.
Conclusion
To wrap up, your choice between the HMX FJ400 and the TTC Gold Red linear switch will largely depend on your personal preferences and usage scenarios. If you prefer a balanced sound profile and a moderately heavier actuation force at 58 grams, the FJ400 is a suitable option, especially if you enjoy a more defined key feel and sound that is not overly dramatic—ideal for a semi-professional environment or if you simply enjoy a little extra weight in your keys. On the other hand, if you favor a lighter touch for fast-paced gaming or typing, the TTC Gold Red with its 50-gram force offers an exceptionally smooth and silky feel, perfect for those who appreciate a gentle yet responsive typing experience. Its thocky, low-pitched sound also adds a subtle personality to your keyboard, making it an excellent choice for shared spaces where quieter switches might be preferred. Ultimately, whether you lean towards the FJ400’s balanced approach or the Gold Red’s refined smoothness, both switches provide unique advantages that cater to different typing styles and environments.
