HMX FJ400 vs. Bsun Jade Rosales
An in-depth look at the HMX FJ400 and the Bsun Jade Rosales switches—which one is the best fit for you?
Overview
When it comes to choosing the perfect mechanical keyboard switch, the decision often boils down to the specific feel and sound each switch offers. The HMX FJ400, a linear switch, serves as the middle ground in the HMX Film switch lineup, delivering a balanced sound profile that appeals to those seeking a more muted typing experience without sacrificing responsiveness. In contrast, the Bsun Jade Rosales, also a linear switch, stands out for its meticulous refinement, developed over a year by XY Studio, incorporating custom housings, stems, and lubrication techniques to provide an exceptionally smooth typing feel. While the FJ400 is ideal for users who appreciate a more tempered auditory experience, the Jade Rosales is tailored for those looking for peak performance in smoothness and tactile satisfaction. However, let's dive in a bit deeper beyond generalities so you can best decide on the switch that suits your typing style and preferences.

Housing materials
When comparing the housing materials of the HMX FJ400 and the Bsun Jade Rosales, distinct characteristics and resulting sound profiles emerge based on the materials used in their construction. The FJ400 features a POM (polyoxymethylene) top housing, known for its ability to produce a deeper and more muted sound. This contrasts sharply with the polycarbonate top housing of the Jade Rosales, which delivers a sharper, higher-pitched, and crisper sound profile. The inherent stiffness of polycarbonate contributes to this clarity, which is particularly beneficial for those who appreciate bright and resonant auditory feedback. Additionally, the translucency of the polycarbonate top housing enhances RGB lighting effects, making the Jade Rosales visually striking as well as acoustically distinct.
On the lower end, the FJ400's nylon bottom housing is lauded for its classic qualities, providing a deeper and fuller sound due to nylon's softer nature, which absorbs sound rather than amplifying it. This results in a duller, rounder auditory experience. In contrast, the Jade Rosales employs a proprietary "Custom Milky Material" for its bottom housing, which, while less defined in description compared to nylon, is intended to create a unique acoustic environment. The combination of the two materials in a switch—nylon in the FJ400 and a custom blend in the Jade Rosales—suggests that they will each contribute to the bottoming-out feel and sound. The differences in material selection on the bottom housing can be expected to influence the final sound profile, affecting how the switches respond overall when pressed.
Ultimately, while the HMX FJ400 and Bsun Jade Rosales utilize different materials for their housing, the fundamental framework of sound and feel is shaped by the interaction between the top and bottom components. In both cases, the top housing is responsible for the sound profile on release, while the bottom housing affects bottom-out sound and feel, effectively distributing their unique tonal qualities. If matched with switches that concert similar materials and properties, it is possible to achieve satisfying results with comparable auditory and tactile experiences, despite the differences in their initial design choices.
Weight
When comparing the actuation and bottom out forces of the HMX FJ400 linear switch and the Bsun Jade Rosales linear switch, notable differences emerge. The FJ400 has an actuation force of 50 grams and a bottom out force of 58 grams, while the Jade Rosales features a lighter actuation force of 45 grams and a bottom out force of 53 grams. This means that the FJ400 requires a slightly heavier push to register a keystroke and to bottom out, making it more suitable for typists who prefer a firmer feel. In contrast, the lighter actuation and bottom out forces of the Jade Rosales may appeal to users who favor longer typing sessions or gaming due to reduced effort. Ultimately, those who lean towards a heavier touch may find the FJ400 more satisfying, while those seeking a softer experience might opt for the Jade Rosales.
Travel distance
When comparing the travel distances of the HMX FJ400 linear switch and the Bsun Jade Rosales linear switch, we find that they differ slightly, with the FJ400 having a travel distance of 3.8 mm and the Jade Rosales at 3.5 mm. This makes the Jade Rosales the shorter option, catering to those who prefer a more responsive feel that is often favored by gamers. In contrast, the FJ400 offers a deeper travel distance, which may appeal to users who enjoy a more substantial keypress experience. While both switches provide a quality typing experience, their differing travel distances allow for personal preference to dictate which switch is best suited for individual needs—shorter for swift reactions or longer for a more deliberate typing feel.

Typing experience
The HMX FJ400 linear switch is known for its balanced sound profile, making it a versatile option for users who appreciate a more subtle auditory experience without overwhelming noise. This characteristic allows it to blend seamlessly into various environments, whether in an office or at home. On the other hand, the Bsun Jade Rosales switch is crafted to deliver an exceptionally smooth and refined auditory output, enhanced by meticulous construction and lubrication techniques. Both switches, however, will be influenced by other factors, such as the keyboard's construction and the choice of keycaps, meaning that sound perception can vary significantly based on these elements.
When it comes to feel, the FJ400 provides a smooth and balanced typing experience that appeals to a wide range of users. It strikes a middle ground, making it suitable for both typing and gaming without any harsh tactile feedback. Conversely, the Jade Rosales switch emphasizes an incredibly smooth feel due to its custom housing and stem design, which is a product of extensive refinement over the course of a year. This focus on smoothness may grant a more luxurious experience for dedicated typists or gamers seeking precision.
In conclusion, the HMX FJ400 and Bsun Jade Rosales linear switches both offer distinct yet appealing qualities in terms of sound and feel. The FJ400’s balanced sound and versatile feel make it suitable for a wide audience, while the Jade Rosales shines with its refined smoothness and auditory quality. Ultimately, both switches promise a satisfying experience; however, the choice between them may come down to personal preference regarding sound and tactile feedback.
Conclusion
To conclude, when selecting between the HMX FJ400 and the Bsun Jade Rosales linear switches, your choice should align with your personal preferences for actuation force and overall typing experience. If you prefer a bit of resistance while typing and enjoy a balanced sound profile, the FJ400, with its 58 grams of bottom-out force, may be the ideal option for you. Its construction positions it as a solid middle ground, making it versatile enough for both typing and gaming, delivering a satisfying tactile feedback that can improve your overall productivity. On the other hand, if you seek a smoother typing experience and a lighter feel with a bottom-out force of only 53 grams, the Jade Rosales will likely suit you better. The meticulous refinement of its design ensures that it provides excellent responsiveness, making it a fantastic choice for extended typing sessions or for users who prioritize a silky-smooth keystroke. Ultimately, your decision should reflect whether you lean towards a slightly heavier and more pronounced feel or a lighter and smoother experience.
