HMX FJ400 vs. Gateron Melodic
An in-depth look at the HMX FJ400 and the Gateron Melodic switches—which one is the best fit for you?
Overview
When it comes to choosing the right mechanical keyboard switch, the decision often comes down to personal preference and intended use. On one hand, the HMX FJ400 linear switch is celebrated for providing a balanced sound profile, making it an excellent choice for those seeking a more understated typing experience. It appeals to users who prioritize smooth key presses and silent operation, perfect for office environments or late-night gaming sessions. On the other hand, the Gateron Melodic clicky switch breathes new life into the clicky switch category with its innovative design that features smooth factory lubing and dual-railed stems. This switch embraces the satisfying click and tactile feedback that many typists and gamers crave, offering a fun and engaging experience. While the FJ400 provides a sleek, unobtrusive feel, the Melodic introduces a layer of auditory excitement that can enhance the typing experience. However, let’s dive in a bit deeper beyond generalities so you can best decide on the switch that suits your individual needs.

Housing materials
The HMX FJ400 and Gateron Melodic switches exhibit distinct differences in their top housing materials, significantly influencing their overall sound profiles. The FJ400 utilizes a POM top housing, known for producing a more muted and deeper sound, which contributes to a unique auditory experience when typing. This particular sound characteristic is achieved through the material's inherent acoustic properties, which dampen sound more effectively. In contrast, the Melodic features a polycarbonate top housing that yields a sharper, higher-pitched, and crisper sound profile, thanks to the stiffness of polycarbonate. The clearer resonant sound from the Melodic's housing is particularly emphasized when the switch is illuminated with RGB lighting, which adds an aesthetic appeal that is not only functional but also visually striking.
When considering the bottom housing, both the FJ400 and Melodic share the same material—nylon. This unification results in a similar sound profile being produced when the key is bottomed out. Nylon is revered in the keyboard community for its ability to create a fuller, deeper sound due to its softer composition, which absorbs impact and vibrations more effectively. As a result, the bottoming out of both switches will manifest a satisfying thud, resonating with users who prefer more subdued key presses. This shared bottom housing material allows both switches to deliver a consistent auditory experience, contributing to their appeal among enthusiasts who appreciate depth in sound.
Ultimately, the interplay between the different top and bottom housing materials in both switches leads to unique, yet overlapping, acoustic results. The FJ400's POM top housing provides a deeper and more muted sound upon release, while the nylon bottom housing reinforces that fullness when pressed. Conversely, the Gateron Melodic's sharper top housing, combined with the same nylon bottom housing, guarantees a crisp auditory feedback and clarity upon actuation. In a way, both switches harness the benefits of their respective materials to create an engaging typing experience, where the distinct identities of the top housings are complemented by the deeper sound signature offered by the nylon bottom. Overall, enthusiasts may choose between the two based on their sound preferences, knowing that the nylon bottom will maintain a consistent depth across both options.
Weight
When comparing the HMX FJ400 linear switch and the Gateron Melodic clicky switch, there are notable contrasts in their actuation and bottom out forces. 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 provides a balanced typing experience. In contrast, the Gateron Melodic clicky switch has an unspecified actuation force, but it does have a bottom out force of 60 grams, which is also medium. As for the weight comparison, the FJ400 is definitively the lighter option with its actuating force of 50 grams, while the Melodic, with a higher unspecified actuation force but a bottom out force of 60 grams, suggests a heavier typing experience. For users who prioritize lighter switches for extended typing or gaming sessions, the FJ400 would be the preferred choice, whereas those who enjoy a firmer push may find the Gateron Melodic more to their liking, especially considering its potentially heavier actuation.
Travel distance
When comparing the travel distances of the HMX FJ400 linear switch and the Gateron Melodic clicky switch, we find that the FJ400 has a travel distance of 3.8 mm, while the Melodic features a slightly longer travel distance of 4 mm. This means that the FJ400 is the shorter option, catering to users who prefer a more responsive keypress suitable for fast-paced gaming. On the other hand, the Melodic's 4 mm travel distance aligns with the more traditional switch specifications, providing a deeper, more substantial feel that some users may find more satisfying. Ultimately, choosing between these two switches comes down to personal preference: the FJ400 is ideal for those favoring responsiveness, while the Melodic may appeal to those who appreciate a more pronounced depth in their key presses.

Typing experience
In terms of sound, the HMX FJ400 linear switch offers a balanced sound profile that makes it versatile for various environments without being overly intrusive. This contrasts with the Gateron Melodic clicky switch, which delivers a resonant and crunchy auditory experience. Typing on the Melodic provides a higher-pitched, sharp sound paired with a satisfying crunch, reminiscent of stepping on autumn leaves. The clear and immersive sound of the Melodic enhances the tactile feedback, making it more engaging for those who enjoy the clicky experience. However, both switches' sound can also be influenced by the choice of keyboard and keycap materials.
When it comes to feel, the FJ400 is a smooth linear switch, providing an uninterrupted keystroke experience that some users may find comforting for rapid typing. On the other hand, the Gateron Melodic clicky switch features a buttery feel, characterized by a seamless and fluid typing sensation. This smoother action, combined with the tactile feedback that accompanies its clicky nature, creates a typing experience that's both pleasing and responsive. While these switches differ significantly in tactile feedback, users seeking a purely linear feel will appreciate the FJ400, while those who prefer tactile moments will lean towards the Melodic.
In conclusion, the HMX FJ400 linear switch presents a balanced auditory experience with a smooth keystroke that is ideal for users looking for simplicity and understated performance. In contrast, the Gateron Melodic clicky switch stands out with its engaging resonant sound and buttery feel, perfect for those who enjoy more tactile feedback and auditory satisfaction while typing. Each switch caters to different preferences, so users should consider their typing styles and sound preferences when choosing between them.
Conclusion
To conclude, your choice between the HMX FJ400 linear switch and the Gateron Melodic clicky switch ultimately comes down to your personal preferences and typing style. If you favor a smoother, more linear experience with a balanced sound profile, the FJ400 is a solid choice. Its medium actuation force of 58 grams strikes a great balance for those who enjoy a gentle but responsive keystroke, making it ideal for long typing sessions or gaming where feel and consistency are crucial. On the other hand, if you relish a tactile and auditory feedback experience that adds a unique character to your typing, the Gateron Melodic may be more to your liking. With its resonant and crunchy sounds paired with a buttery feel, this switch can enhance the enjoyment of both gaming and typing, appealing to those who appreciate the classic clicky switch while still benefiting from modern advancements like smooth factory lubing. Remember to consider whether you prioritize sound and tactility or prefer a clean and smooth keystroke, as both switches cater to different aspects of the typing experience.
