HMX FJ400 vs. Gazzew LT

Overview

When exploring mechanical keyboard switches, two notable options stand out: the HMX FJ400 and the Gazzew LT. The FJ400 serves as a balanced choice within the HMX Film switch lineup, renowned for its versatile sound profile that caters to both casual typists and gamers alike, making it an ideal candidate for those seeking a harmonious typing experience without overwhelming noise. On the other hand, the Gazzew LT switches, distinguished by their charming lilac hue, are celebrated for their deep, resonant "thock" sound, providing a tactile enjoyment that can elevate the typing experience for enthusiasts who appreciate auditory feedback. While the FJ400 presents itself as a middle ground for versatility, the LT focuses more on a rich auditory experience, creating a unique appeal. 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 Gazzew LT, both switches feature unique compositions that lead to distinctive auditory profiles. The FJ400 utilizes a POM top housing known for producing a pleasing, deeper sound that tends to be more muted. This characteristic contributes to a softer acoustic reflection when typing, making the experience rich and balanced. On the other hand, the Gazzew LT employs a proprietary "boba plastic" blend for its top housing, which is also designed to deliver a similar deep sound profile due to its inherent softness. While the specific materials differ, both create an auditory environment that is rich and textured, showcasing how different plastics can achieve comparable sound qualities.

The bottom housing of the two switches further highlights both congruencies and distinctions in performance. The FJ400 features a nylon bottom housing, a material celebrated in the mechanical keyboard community for its classic role in generating a deeper, fuller sound. Nylon's softer nature allows it to absorb sound effectively, contributing to a duller and more rounded auditory experience at the bottom-out. In contrast, the Gazzew LT continues the theme of softness in its proprietary blend for the bottom housing, also promoting a resonant and rich sound profile. Although the specific materials differ, the shared emphasis on softness in both switches lends to a similar overall auditory experience when bottoming out.

Consequently, the combined attributes of the FJ400's and the Gazzew LT's housing materials showcase a fascinating interplay of sound characteristics. The distinctive impacts of the top and bottom housings mean that sound profiles are not merely derived from a single component but from the synergy between both. While the materials used in the top and bottom housings vary, their shared focus on softness results in a cohesive auditory quality that is pleasing to the typist. Thus, despite the differences, both switches can offer users a similar depth and richness in sound, further emphasizing the importance of housing material in achieving an informed and detailed typing experience.

Weight

When comparing the HMX FJ400 linear switch and the Gazzew LT linear switch, it is notable that the actuation force for the FJ400 is set at 50 grams, which allows for a responsive feel during keystrokes. In contrast, the actuation force for the LT switch is unknown, making it difficult to quantify how it compares in this aspect. However, the bottom out force for the FJ400 is 58 grams, while the LT has a heavier bottom out force of 65 grams. This indicates that while the FJ400 is lighter overall, the LT offers a more substantial bottom out feel during typing. The lighter actuation force of the FJ400 may appeal to those who prioritize comfort during extended typing or gaming sessions, whereas the heavier bottom out force of the LT switch caters to users who prefer a more pronounced tactile experience. Thus, users should consider their preferences for actuation feedback when choosing between these two switches.

Travel distance

When comparing the travel distance of the HMX FJ400 linear switch and the Gazzew LT linear switch, the FJ400 offers a longer travel distance of 3.8 mm, while the LT features a shorter travel distance of 3.2 mm. This difference implies that the FJ400 may provide a more traditional typing experience with a greater sense of depth, which some users may prefer for comfort and feel. Conversely, the LT's 3.2 mm travel distance caters to those who prioritize responsiveness, making it an appealing choice for gamers seeking faster key actuation. Ultimately, the choice between the two switches will depend on an individual's preference for either more depth or quicker response times, with the FJ400 being the option for a heartier feel and the LT better suited for rapid-typing enthusiasts.

Typing experience

When it comes to sound, the HMX FJ400 linear switch strikes a balanced tone, providing a well-rounded auditory experience that fits comfortably in various typing environments. In contrast, the Gazzew LT linear switch is known for its deep, resonant thockiness, characterized by bassy, low-pitched sounds that create a satisfying acoustic signature with each keystroke. The LT’s auditory experience is often described as an "auditory symphony," offering a deeper and richer profile reminiscent of a soft thud or knock. While both switches can produce pleasing sounds, the depth and richness of the LT are particularly striking, giving it a more immersive acoustic characteristic compared to the more neutral performance of the FJ400.

In terms of feel, the specifics of the FJ400's tactile experience are not provided, but it is important to note that the switch is considered a middle ground in the HMX Film switch lineup, which suggests a generally agreeable typing sensation. The Gazzew LT, on the other hand, excels in offering a seamless glide with each keystroke, promoting a smooth typing experience that can enhance overall comfort and efficiency. This smoothness is a differentiating factor, as it can lead to a more enjoyable typing experience when compared to the unspecified feel of the FJ400.

In summary, while the HMX FJ400 linear switch features a more balanced sound profile and an unspecified feel likely appealing to a broad range of users, the Gazzew LT linear switch delivers a captivating auditory experience defined by its deep, thocky sound and a notably smooth feel. If you're seeking a balance and reliability, the FJ400 may suit you well, but if you desire a robust auditory sensation combined with a fluid typing experience, the LT could be the ideal choice. Ultimately, both switches cater to different preferences, meaning your choice will significantly influence your overall typing experience.

Conclusion

To conclude, when deciding between the HMX FJ400 and the Gazzew LT linear switches, your choice should largely depend on your personal preferences regarding actuation force, sound profile, and tactile feedback. If you prefer a switch that strikes a balance with a medium actuation force of 58 grams, the FJ400 will likely work well for you, especially if you're looking for a versatile sound profile that won’t overpower your surroundings. It’s ideal for those who want a more understated experience while still enjoying a satisfying typing feel. On the other hand, if you’re someone who enjoys a slightly heavier keystroke with a bottom-out force of 65 grams and craves a deeper, richer auditory feedback, the Gazzew LT switches may be the perfect match. Their unique thocky sound provides an engaging typing experience that can be particularly rewarding during long typing sessions or gaming. Ultimately, consider what matters most to you—whether it’s the balanced yet subtle characteristics of the FJ400 or the bassy, thocky appeal of the LT switches—as this will guide you toward making the best decision for your mechanical keyboard setup.
