HMX FJ400 vs. TTC Gold Brown Pro

An in-depth look at the HMX FJ400 and the TTC Gold Brown Pro switches—which one is the best fit for you?

Overview

When it comes to mechanical keyboard switches, the choice between linear and tactile can significantly influence your typing experience, particularly when comparing models like the HMX FJ400 and the TTC Gold Brown Pro. The FJ400, a linear switch, is renowned for its balanced sound profile, making it a versatile option for both gaming and typing. It provides a smooth keystroke with no tactile feedback, allowing for rapid key presses without interruption, which many gamers favor for fast-paced action. On the other hand, the TTC Gold Brown Pro caters to those seeking a more nuanced experience, characterized by a gentle tactile bump that enhances typists' connection to the keyboard without overwhelming their focus. Its subdued sound and subtle feedback allow for a quiet, immersive typing session, ideal for office environments or long writing marathons. Both switches offer unique advantages: the FJ400 for those who prioritize speed and fluidity, while the Gold Brown Pro appeals to users who appreciate a softer, more restrained tactile response. However, let's dive in a bit deeper beyond generalities so you can best decide on the switch that suits your individual preferences and needs.

Housing materials

When comparing the housing materials of the HMX FJ400 and the TTC Gold Brown Pro, a clear distinction emerges between their top housings. The FJ400 features a POM (Polyoxymethylene) top housing, noted for its ability to produce a deeper and more muted sound profile. This material contributes to a unique auditory experience that is appealing to users who prefer a sound that isn’t too overpowering. In contrast, the Gold Brown Pro utilizes a polycarbonate top housing, renowned for creating a sharper, higher-pitched, and crisper sound. The intrinsic stiffness of polycarbonate enhances the clarity and resonance of the sound, resulting in a more articulate auditory feedback. Therefore, while both switches can offer satisfying results, their sound profiles are shaped distinctly by the materials used in their top housings.

Both switches share a commonality in their bottom housings, both crafted from nylon. This material is well-regarded in the keyboard community for producing a deeper and fuller sound profile that complements the overall typing experience. Nylon's softer characteristics absorb sound waves, resulting in a somewhat muted and rounder sound that may appeal to users looking for a more subdued auditory feedback. Because both the FJ400 and the Gold Brown Pro feature nylon as their bottom housing, users can expect similar auditory experiences when it comes to how the switches feel upon bottoming out. The result is a softer impact that enhances typing comfort across both switch types, despite the contrasting acoustic properties of their top housings.

The interplay of these materials also influences the overall sound signature when typing. The top housing's characteristics will govern the sound produced upon releasing a key, while the bottom housing predominantly impacts the sound and feel when the switch is bottomed out. Thus, the HMX FJ400’s POM top provides a more muted sound upon release, while the TTC Gold Brown Pro’s polycarbonate top adds brightness and clarity to the overall performance. In practice, this means that while users of either switch can enjoy a deeper auditory experience thanks to the nylon bottom, the distinct qualities of the top housings will cater to different preferences, leading to a diverse typing soundscape across the two models.

Weight

When comparing the HMX FJ400 linear switch with its actuation force of 50 grams and bottom out force of 58 grams to the TTC Gold Brown Pro tactile switch, which boasts an actuation force of 45 grams but lacks an available bottom out force measurement, we can see some notable differences in terms of actuation force. The FJ400 requires a slightly heavier actuation force, making it feel more substantial when typing. This may appeal to users who prefer a firmer push sensation in their keystrokes. In contrast, the Gold Brown Pro, with its lighter actuation force, might be favored by those who seek a less strenuous typing experience, allowing for extended use without fatigue. However, due to the lack of information regarding the bottom out force of the Gold Brown Pro, we cannot draw a comparison in that specific area. Thus, for users who prioritize a lighter switch for more prolonged activities, the TTC Gold Brown Pro appears to be the better option, while the HMX FJ400 caters to those who enjoy a heavier, more tactile typing experience.

Travel distance

Both the HMX FJ400 linear switch and the TTC Gold Brown Pro tactile switch share the same travel distance of 3.8 mm, resulting in similar keypress experiences. Since both switches travel the same distance from top to bottom, users can expect comparable results in terms of key feel and actuation. This uniformity in travel distance allows for a consistent typing or gaming experience across both switch types, making them equally effective for those who favor a 3.8 mm actuation distance.

Typing experience

In terms of sound, the HMX FJ400 linear switch features a balanced profile that doesn't draw too much attention to itself, often described as a neutral sound experience. This makes it versatile for various environments, whether home, work, or gaming. In contrast, the TTC Gold Brown Pro tactile switch delivers a thocky sound characterized by a deep, rich tone akin to a soft "knock" or a gentle thud when keys are pressed. It possesses a low-pitched quality that is mellow compared to higher-pitched alternatives, enabling a satisfying auditory feedback without overpowering the overall typing experience. Both switches prioritize muted sounds, but the Gold Brown Pro offers a more distinct auditory signature that enhances the tactile feedback it imparts.

When considering the feel, the FJ400 switch is recognized for its smooth action, perfect for users who seek simplicity and efficiency in their typing experience. Although the exact descriptors for its feel weren't provided, it can be inferred that its linear nature allows for uninterrupted key travel without the interference of tactile bumps. Meanwhile, the TTC Gold Brown Pro boasts several refined characteristics, including polished and silky finishes that promote effortless key presses with minimal friction. The mild resistance of its stepped tactile feedback allows for a subtle but noticeable response during typing, creating a gentle experience that won't overwhelm users. As a result, while the FJ400 leans towards a streamlined feel, the Gold Brown Pro engages typists with a carefully calibrated tactile interaction.

Overall, both the HMX FJ400 linear switch and the TTC Gold Brown Pro tactile switch cater to different preferences in sound and feel. The FJ400 offers a balanced auditory experience suitable for various settings, focusing more on a smooth keypress trajectory, while the Gold Brown Pro combines a unique sound profile with a rich tactile feedback that supports a more immersive typing experience. Ultimately, the choice between the two will depend on whether you prioritize auditory subtlety and tactile engagement or prefer a singularly smooth keystroke devoid of tactile distractions.

Conclusion

To wrap up, the choice between the HMX FJ400 linear switch and the TTC Gold Brown Pro tactile switch ultimately hinges on your personal typing style and preferences. If you appreciate a smooth and direct typing experience without any tactile feedback, the FJ400 is a compelling option. Its medium bottom-out force of 58 grams strikes a balanced feel, making it suitable for both casual typing and more intense gaming sessions. Additionally, the FJ400’s sound profile is neutral, allowing it to fit seamlessly in a variety of environments without drawing undue attention. On the other hand, if you prefer a more nuanced and subtle tactile experience, the TTC Gold Brown Pro is the way to go. Its gentle bump provides just enough feedback to keep your fingers engaged without being intrusive, making it ideal for long hours of focused typing or working in quieter shared spaces. The Gold Brown Pro’s polished and silky feel ensures a captivating typing experience, complemented by its thocky, low-pitched sound that adds richness without overwhelming your auditory senses. Ultimately, your decision should reflect whether you seek a straightforward linear response or a understated tactile engagement in your keyboard experience.
