HMX FJ400 vs. HMX Sunset Gleam
An in-depth look at the HMX FJ400 and the HMX Sunset Gleam switches—which one is the best fit for you?
Overview
When selecting a mechanical keyboard switch, it's essential to find a balance between performance, sound, and feel. The HMX FJ400 and the HMX Sunset Gleam, both linear switches, present unique characteristics that cater to different user preferences. The FJ400 stands out as a versatile option within the HMX Film switch lineup, boasting a balanced sound profile that appeals to gamers and typists seeking a smooth, consistent keystroke. In contrast, the Sunset Gleam, also referred to as the Duck Duck switch, introduces a delightful combination of materials that deliver both a subtle top-out and a satisfying clack, enhanced by HMX's reputable factory lubrication. While the FJ400 serves as a reliable middle ground for those who prioritize a muted yet efficient typing experience, the Sunset Gleam offers a bit more personality for users who enjoy auditory feedback without compromising on smoothness. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The HMX FJ400 and HMX Sunset Gleam showcase distinct housing materials that significantly influence their auditory characteristics. The top housing of the FJ400 employs POM, known to produce a deeper, more muted sound profile. This characteristic contrasts sharply with the Sunset Gleam's polycarbonate top housing, which delivers a sharper, higher-pitched, and crisper sound. While both switches use nylon for their bottom housings, the difference in the top housing materials leads to a distinct division of auditory properties. The FJ400's POM top softens the sound when keys are released, whereas the Sunset Gleam's polycarbonate enhances clarity and resonance, making it more pronounced when typing.
Both switches incorporate nylon in their bottom housings, leading to a shared auditory experience when it comes to bottoming out. As both switches utilize nylon, they provide a deeper and fuller sound profile that absorbs sound effectively. This similarity means that, although the top housing materials vary considerably—creating contrasting upper sound profiles—typists will enjoy a consistent and comfortable experience as the nylon dampens the noise during key presses on both switches. Thus, regardless of the distinct sounds created above, the fundamental typing experience remains deep and round due to the materials used in the bottom housings.
The interplay between the top and bottom housing materials results in unique sound profiles while retaining some common ground. If you desire a punchier response with bright peaks, the Sunset Gleam's polycarbonate top housing will stand out, especially when paired with RGB lighting for a visually enhanced experience. Conversely, the FJ400 will appeal to those who prefer a more muted, deeper resonance created by the POM top housing. Ultimately, while the two switches owe their identity to the differences in top housing materials, the shared nylon bottom housing ensures that both maintain a rich and enjoyable typing experience.
Weight
When comparing the HMX FJ400 linear switch and the HMX Sunset Gleam linear switch, notable differences in both actuation force and bottom out force arise. The FJ400 features a medium actuation force of 50 grams and a bottom out force of 58 grams, making it feel significantly sturdier during use. In contrast, the Sunset Gleam presents a lighter touch with an actuation force of 42 grams and a bottom out force of 48 grams. This lighter configuration is ideal for those who prefer prolonged typing sessions or gaming, as it may reduce finger fatigue. Consequently, users seeking a more substantial typing experience would gravitate towards the FJ400 due to its heavier forces, while those valuing a lighter touch would opt for the Sunset Gleam. This divergence in weight preference highlights the subjective nature of switch selection based on individual typing styles and comfort levels.
Travel distance
When comparing the travel distance of the HMX FJ400 linear switch and the HMX Sunset Gleam linear switch, it's clear that they cater to different preferences in tactile feedback. The FJ400 features a travel distance of 3.8 mm, making it the longer option, while the Sunset Gleam has a slightly shorter travel distance of 3.5 mm. For gamers or users who prioritize quick response times, the shorter travel distance of the Sunset Gleam may provide a more sensitive feel and quicker actuation. On the other hand, those who enjoy a more pronounced key press and a sense of depth might find the 3.8 mm travel of the FJ400 to be more appealing. Ultimately, the choice between these two switches will depend on personal preference regarding responsiveness versus depth in typing experience.

Typing experience
In terms of sound, the HMX FJ400 linear switch offers a balanced sound profile, making it versatile for various typing environments. This neutrality allows it to neither be overly loud nor too muted, striking a harmonious balance that appeals to many users. In contrast, the HMX Sunset Gleam excels in delivering a subtle top-out accompanied by a satisfying clack. This combination caters to those who enjoy a more pronounced auditory response without being abrasive. It's important to recognize that the sound produced by any switch can also be influenced by the keyboard's build and the choice of keycaps, which adds an additional layer of personalization to the auditory experience.
Regarding feel, the FJ400 is characterized by its smooth yet deliberate actuation, striking a comfortable balance that allows for rapid typing without being too soft or overly stiff. Users can expect a consistent tactile experience across the actuation point, providing a level of reliability that is appreciated in daily use. On the other hand, the Sunset Gleam switch provides a distinct feeling marked by excellent factory lube that enhances the overall smoothness and encourages a fluid typing experience. This careful craftsmanship contributes to a luxurious touch that many enthusiasts will find gratifying, making the Sunset Gleam inviting for long typing sessions.
Considering both sound and feel, the HMX FJ400 and HMX Sunset Gleam switches cater to slightly different preferences while maintaining high-quality performance. The FJ400's balanced sound and smooth actuation make it a great all-around option, whereas the Sunset Gleam offers a more engaging auditory experience combined with a comfortable and luxurious touch. Both switches promise a satisfying typing experience, but your choice will ultimately depend on whether you value an understated sound profile with reliable performance or a more tactile and audibly pleasing interaction with your keyboard.
Conclusion
To conclude, when deciding between the HMX FJ400 linear switch and the HMX Sunset Gleam linear switch, consider your typing preferences and the type of experience you seek. If you want a switch that offers a medium bottom-out force of 58 grams, making it suitable for varied typing styles while providing a balanced sound profile, then the FJ400 is an excellent choice. It’s ideal for users who appreciate a more tactile response without being too overwhelming, making it versatile for both casual and professional use. On the other hand, if you prefer a lighter touch with a bottom-out force of just 48 grams, the Sunset Gleam may be better suited for you. Its combination of lightness and satisfying clack offers a delightful experience, particularly for those who enjoy a more spirited response and might be engaging in rapid-fire typing or gaming sessions where quick action is crucial. Ultimately, your choice depends on how much resistance you prefer and the overall sound and feel you desire from your mechanical keyboard.
