HMX FJ400 vs. Cherry MX Red

An in-depth look at the HMX FJ400 and the Cherry MX Red switches—which one is the best fit for you?

Overview

When it comes to choosing mechanical keyboard switches, both the HMX FJ400 and the Cherry MX Red present unique advantages that cater to different typing preferences and experiences. The HMX FJ400, positioned as the middle ground in the HMX Film switch lineup, is recognized for its balanced sound profile, making it an appealing option for users who seek a harmonious auditory experience without overwhelming noise. In contrast, the Cherry MX Red, a classic in the mechanical keyboard world, is celebrated for its slightly heftier feel coupled with a deeper, "thocky" sound profile. This switch offers a robust typing experience, merging responsiveness with a satisfying acoustic depth. While both switches fall into the linear category, catering to those who prefer smooth keystrokes without tactile feedback, their distinct characteristics may lead users to favor one over the other. However, let's dive in a bit deeper beyond generalities so you can best decide on the switch that suits your preferences.

Housing materials

When comparing the housing materials of the HMX FJ400 and the Cherry MX Red switches, both exhibit a notable focus on sound profile attributed to the materials used. The HMX FJ400 utilizes a POM top housing, praised for its unique sound characteristics that lean towards a deeper and more muted tone. In contrast, the Cherry MX Red features a nylon top housing, which is renowned for creating a similarly deep and fuller sound profile. The main difference lies in the specific properties of the materials; while POM offers a distinct auditory experience, nylon is celebrated for its ability to absorb sound more efficiently, resulting in a rounded sound profile during typing. Despite these differences, both materials produce satisfying auditory results that can create an enjoyable typing experience.

Turning to the bottom housing, both the FJ400 and MX Red incorporate nylon as their material of choice. This decision significantly influences the overall sound produced while typing, since nylon's softer composition contributes to a muted auditory output that many users find appealing. Here, both switches share a commonality; with the nylon bottom housing, each switch ensures a deeper, fuller sound that softens the impact upon bottoming out. This similarity suggests that regardless of the variation in top housing materials, users of either switch will experience a comparable auditory richness when pressing down on the keys.

In terms of tactile feedback and sound profiles, the differences in top housing materials influence how the switches feel and sound during different states of use. The POM top housing of the FJ400 emphasizes the sound when releasing the key, while the nylon in both switches allows for a consistent lower sound during key presses. Therefore, the experience of using the switches may vary; however, the shared characteristic of nylon in the bottom housing leads to similar sound profiles upon bottoming out, ultimately providing a deeper and more pleasant sound framework. Consequently, users can anticipate a satisfying experience whether they choose the FJ400 or the Cherry MX Red, with each switch offering its unique blend of auditory satisfaction shaped by its housing materials.

Weight

The HMX FJ400 linear switch and the Cherry MX Red linear switch present a notable comparison in their actuation forces, while the bottom out force for the MX Red remains unspecified. The FJ400 features a slightly higher actuation force of 50 grams compared to the Cherry MX Red's 45 grams, making the FJ400 feel heavier during use. This might appeal to users who prefer a more substantial typing experience, often favoring the tactile feedback offered by heavier switches. However, the lighter actuation force of the MX Red could be advantageous for those engaged in long typing sessions or gaming, as it requires less effort to actuate the key. Moreover, the FJ400 has a bottom out force of 58 grams, while the bottom out force for the Cherry MX Red is unknown; this lack of information may leave potential users uncertain about the overall resistance felt when fully engaged. In summary, while both switches can offer a satisfying typing experience, the FJ400 is the heavier option, while the Cherry MX Red caters to those who prefer a lighter touch, making it suitable for extended use.

Travel distance

When comparing the travel distances of the HMX FJ400 linear switch and the Cherry MX Red linear switch, we find that they differ slightly, with the FJ400 featuring a travel distance of 3.8 mm, while the MX Red has a travel distance of 4.0 mm. This difference means that the FJ400 offers a shorter travel distance, which may appeal to gamers seeking quicker response times. On the other hand, the MX Red, with its traditional 4 mm travel, provides a deeper keystroke that some users may find more satisfying. Ultimately, the choice between these two switches will depend on personal preference: those who favor a more responsive feel may opt for the FJ400, while users who appreciate a more pronounced depth in their keystrokes might prefer the Cherry MX Red.

Typing experience

When considering the sound of the HMX FJ400 linear switch compared to the Cherry MX Red linear switch, there are notable differences. The FJ400 is known for its balanced sound profile, providing a moderate auditory feedback that appeals to those who appreciate a more restrained acoustics during typing. In contrast, the MX Red offers a deeper sound characterized by a thocky resonance, reminiscent of a satisfying "thud" or soft "knock." This low-pitched auditory experience gives the MX Red a more robust auditory presence, which can enhance the overall typing experience for users who prefer a richer and more fulfilling sound.

In terms of feel, the FJ400 offers a response that is often framed as the "middle ground" among its counterparts, suggesting a smooth experience but without specific details on texture. On the other hand, the MX Red is recognized for its textured quality, presenting a noticeable friction during key presses. This textured nature can create a tactile distinction that some users find engaging, while others may prefer the more effortless glide that is hinted at with the FJ400. Thus, while the exact feel of the FJ400 may remain ambiguous, it appears that the MX Red provides a more distinct experience, leading to a fundamental difference in user preference based on tactile sensation.

In conclusion, both the HMX FJ400 and Cherry MX Red linear switches present intriguing options for keyboard enthusiasts, appealing to different auditory and tactile preferences. The FJ400's balanced sound pairs with a potentially smooth feel, while the MX Red stands out with its rich, thocky sound and textured feedback. Ultimately, the choice between the two will depend on an individual's priorities in sound and feel, as users can expect similar results in terms of smooth linear actuation from both switches, despite their differing characteristics.

Conclusion

To summarize, when choosing between the HMX FJ400 linear switch and the Cherry MX Red linear switch, your decision should depend on your personal preferences regarding typing feel and sound profile. If you're looking for a versatile switch that offers a balanced sound and a medium actuation force of 58 grams, the FJ400 can provide a satisfying typing experience without being too heavy, making it suitable for both casual typing and gaming. On the other hand, if you prefer a slightly heftier feel combined with a deeper, thocky sound, the MX Red may be more appealing, especially if you enjoy the auditory feedback and textured touch that these switches offer. Consider your use cases: if you’re focused primarily on gaming where speed is essential, the MX Red might lend a more responsive experience, while the FJ400 could serve well in a work environment where a pleasant auditory profile and a moderate feel are advantageous. Ultimately, your choice should reflect what aspects of typing and sound matter the most to you, ensuring that you select a switch that complements your unique typing style and audio preference.
