Housing materials

When comparing the housing materials of the HMX FJ400 and the TTC Gold Red Pro, the most notable difference lies in their top housing compositions. The FJ400 features a POM (polyoxymethylene) top housing, which is known for producing a deeper and more muted sound profile that is described as pleasing and unique. In contrast, the Gold Red Pro utilizes a polycarbonate top housing, which typically delivers a sharper, higher-pitched, and crisper sound due to the material's superior rigidity and acoustic properties. This differentiation in top housing materials not only affects the overall auditory experience of each switch but also influences the interplay between the sound profiles associated with key presses and releases. For example, while the FJ400 has a subdued upper sound profile, the Gold Red Pro’s clear polycarbonate top allows for a more resonant and bright acoustic response, particularly beneficial for setups that leverage RGB lighting.

Despite these differences in top housing materials, both switches feature nylon as their bottom housing material, which helps create a similar auditory foundation. Nylon's properties contribute to a deeper and fuller sound profile by absorbing more sound due to its softer composition; thus, both switches inherently share this acoustic characteristic. As a result, while the FJ400 and the Gold Red Pro diverge in their upper sound signatures, the nylon bottom housing helps unify their overall sound experiences. When typing on both switches, the impact of the nylon material results in a satisfying, muted bottom-out sound that feels consistent across the two designs.

Although the top housing materials yield distinct sound profiles, the shared nylon bottom housing suggests that users can expect a degree of familiarity in terms of feel and auditory feedback when bottoming out on either switch. The difference in sound during key presses comes mainly from the unique characteristics of the top housing; hence, even with contrasting materials, one could still achieve a pleasing typing experience that balances the deeper, fuller tones of nylon with the sharper sounds introduced by the top housing variations. Therefore, users may find that their typing experience is qualitatively enriched by these diverse materials, ultimately allowing for unique but enjoyable switch performances.

Weight

The HMX FJ400 linear switch and the TTC Gold Red Pro linear switch exhibit notable differences in their actuation forces, affecting the typing experience they provide. The FJ400 requires an actuation force of 50 grams, while the Gold Red Pro is lighter at 43 grams. This means that those using the Gold Red Pro may experience less fatigue during extended typing sessions, making it more suitable for users who favor longer work hours or gaming marathons. However, the FJ400's heavier actuation force could appeal to individuals who prefer a more substantial feel when typing, offering a firmer push that some users find satisfying. In terms of bottom out force, the FJ400 has a measurable bottom out force of 58 grams, while the Gold Red Pro’s bottom out force is currently unavailable; thus, a direct comparison cannot be made. Overall, the FJ400 is heavier and might be preferred by those who enjoy a more robust typing experience, while the Gold Red Pro is lighter, likely appealing to users seeking a more effortless keystroke.

Travel distance

Both the HMX FJ400 linear switch and the TTC Gold Red Pro linear switch share the same travel distance of 3.8 mm, which means they provide an equivalent tactile experience when pressed. This similarity in travel distance allows users to expect similar actuation feedback and typing sensations when using either switch. Since their travel distances are equal, one could easily alternate between the two without noticing a significant difference in keypress feel, making both switches suitable for users who prioritize consistency in their keyboard experience.

Price comparison

Typing experience

When comparing the sound characteristics, the HMX FJ400 linear switch offers a balanced sound profile, which makes it harmonious across various settings. In contrast, the TTC Gold Red Pro is characterized by a thocky, low-pitched sound that delivers a deep and pleasing auditory experience during key presses. While both switches aim for a neutral sound, the Gold Red Pro stands out with its rich resonance, providing a more engaging auditory feedback compared to the balanced but less pronounced sound of the FJ400. Overall, users may find that both switches can cater to an array of sound preferences, but the Gold Red Pro leans toward a more satisfying acoustic quality.

In terms of feel, the FJ400's qualities were not detailed, but the TTC Gold Red Pro is known for its polished and silky experience. The Gold Red Pro's smooth finish contributes to reduced friction and an effortless typing experience, marked by its mild and subtle resistance. This user-friendly touch enhances comfort, particularly for prolonged typing sessions, making it appealing to a broad range of users. Comparatively, if the FJ400 offers a similar feel, it would also allow for comfortable and enjoyable typing. However, without specific information on the FJ400, it's difficult to establish a direct comparison.

In conclusion, both the HMX FJ400 and TTC Gold Red Pro linear switches present compelling options for those seeking versatile mechanical keyboard experiences. The Gold Red Pro excels with its thocky sound profile and refined, smooth feel, making it a strong candidate for diverse applications, whether for work or leisure. Although the FJ400 offers a balanced sound, its overall sound and feel qualities remain less defined. As a newcomer, opting for the Gold Red Pro would likely yield a satisfying experience due to its adaptability, while the FJ400 may also be a strong choice if you prefer a more subdued sound profile.

Conclusion

To conclude, your choice between the HMX FJ400 linear switch and the TTC Gold Red Pro linear switch ultimately hinges on your preferences and typing habits. If you appreciate a balanced sound profile and a medium bottom-out force of 58 grams, the FJ400 may be right for you, especially if you seek a straightforward typing experience without unnecessary noise distractions. It can provide a solid typing feel that's neither too light nor too heavy, making it suitable for both work and casual environments. Conversely, if you favor a smooth, polished, and silky typing experience that excels in versatility, the TTC Gold Red Pro is an excellent option. Its low-pitched and thocky sound reinforces its adaptability across various settings, making it ideal for gamers and office users alike. In essence, if you prioritize a more refined, gentle experience with accessible actuation, go for the Gold Red Pro; but if you want a reliable switch with a bit more resistance, the FJ400 might be the better fit.
