An in-depth look at the HMX FJ400 and the HMX Hibiscus switches—which one is the best fit for you?
Overview
When it comes to choosing the right mechanical keyboard switch, the HMX FJ400 and the HMX Hibiscus both offer compelling options for enthusiasts and casual typists alike. The FJ400 stands out as a balanced middle ground in the HMX Film switch lineup, delivering a harmonious sound profile that allows for enjoyable typing experiences in various settings. In contrast, the HMX Hibiscus switches are celebrated for their unparalleled smoothness and a uniquely crisp auditory feedback, making typing feel even more dynamic. With an ultra-light actuation force that surpasses 80% of all switches, the Hibiscus provides a distinct tactile experience that caters to those who prioritize a light touch and auditory satisfaction. While both switches share the linear characteristic, the FJ400 leans more towards a balanced all-rounder, while the Hibiscus focuses on providing a playful, engaging sound profile. However, let's dive in a bit deeper beyond generalities so you can best decide on the perfect switch for you.

Housing materials
In comparing the housing materials of the HMX FJ400 and the HMX Hibiscus, notable distinctions arise from the choice of materials used in their top housings. The FJ400 features a POM (Polyoxymethylene) top housing, known for producing a uniquely deeper and muted sound profile. In contrast, the Hibiscus uses a nylon top housing, which is a classic material associated with switches that yield a fuller sound. While both materials contribute to an enriching auditory experience, the POM housing of the FJ400 emphasizes a more pronounced deepness, whereas the nylon in the Hibiscus absorbs sound more effectively due to its softer nature, resulting in a duller but rounder tone.
When it comes to the bottom housings, both the FJ400 and Hibiscus utilize nylon, which offers shared characteristics despite the differences in their top housing materials. The nylon used in the bottom housing of both switches enables the production of a deeper and fuller sound profile, ensuring that users experience a satisfying auditory feedback. The inherent softness of nylon contributes to sound absorption, helping to create a consistent, rounded acoustic feel during typing. This alignment in materials for the bottom section results in similar performance characteristics, fostering a shared quality in the typing experience of both switches.
Moreover, the impact of housing differences is crucial in understanding the overall feel and sound of each switch when in use. With the FJ400's POM top housing and nylon bottom housing, the bottom-out sound and feel is predominantly influenced by the soft absorption qualities of the nylon, while the top's POM housing primarily affects the release sound. On the other hand, both the Hibiscus and FJ400 benefit from nylon within their bottom structures, which unifies certain auditory qualities across different switch types. Ultimately, both switches deliver a deep and satisfying experience, though their distinct top housing materials create variations in sound when the key is pressed or released.
Weight
When comparing the HMX FJ400 linear switch to the HMX Hibiscus linear switch, there are notable differences in both actuation force and bottom out force. The FJ400 features an actuation force of 50 grams and a bottom out force of 58 grams, making it a medium-weight option that may appeal to those who prefer a more substantial typing experience. In contrast, the Hibiscus offers a lighter actuation force of 42 grams and a bottom out force of 48 grams, which is ideal for users who favor longer typing sessions without fatigue. This clear distinction means that the Hibiscus is the lighter switch, while the FJ400 is the heavier choice. Users seeking responsive feedback with a heavier push should lean towards the FJ400, while those wanting ease of use and a less strenuous feel may find the Hibiscus more suitable for extended use.
Travel distance
When comparing the HMX FJ400 linear switch and the HMX Hibiscus linear switch, we find that the FJ400 has a travel distance of 3.8 mm, while the Hibiscus is slightly shorter at 3.5 mm. This means that the FJ400 offers a more substantial keypress, which may be preferable for users who enjoy a deeper, more tactile experience. In contrast, the Hibiscus, with its shorter travel distance, is likely to provide a quicker response time, making it an appealing choice for gamers or those who favor fast-paced typing. Therefore, if responsiveness is your priority, the Hibiscus may be the ideal option. However, if you appreciate a more pronounced key feel, the FJ400's longer travel distance would be the better selection.

Typing experience
The HMX FJ400 linear switch offers a balanced sound profile, making it versatile for a variety of typing environments. While not overly loud, it provides a pleasant acoustic feedback that suits both typing and gaming. In contrast, the HMX Hibiscus switch creates a distinctly clacky, poppy, and crispy sound signature, delivering a more pronounced audio experience, ideal for those who enjoy a bit more character in their typing sounds. It's important to note that achieving the desired sound may also depend significantly on the keyboard's build and the keycap materials used, so individual experiences may vary.
When it comes to feel, the FJ400 serves as a middle ground within the HMX Film switch lineup, offering a smooth actuation that provides a nice balance between resistance and lightness. This makes it a comfortable option for long typing sessions. On the other hand, the HMX Hibiscus switch is celebrated for its ultra-light actuation force, which collectively with its superior smoothness creates an extraordinarily fluid typing experience. Users may find the Hibiscus significantly easier to press, appealing especially to those who prefer a lighter touch.
In conclusion, while both switches have their unique sound and feel characteristics, they are designed to cater to different preferences and typing styles. The FJ400 provides a balanced acoustic experience and comfortable mid-level resistance, making it suitable for a broader audience, while the Hibiscus boasts a lively and expressive sound along with an ultra-light actuation for a smoother feel. Selecting between the two ultimately depends on individual typing preferences—whether you lean towards a balanced sound or seek a more distinct auditory presence, as well as your tactile preferences in terms of resistance and smoothness during use.
Conclusion
To conclude, the choice between the HMX FJ400 linear switch and the HMX Hibiscus linear switch ultimately hinges on your personal preferences and intended use. If you lean towards a balanced typing experience with a medium bottom out force of 58 grams, the FJ400 could be your ideal match. It's perfect for users who appreciate a moderate feedback level while typing or gaming, making it suitable for long hours of use without fatigue. On the other hand, if you seek an ultra-light touch with a bottom out force of just 48 grams, the Hibiscus switch is designed to deliver a delightfully smooth and lightweight typing experience. This switch excels in scenarios where quick key presses are essential, such as fast-paced gaming or rapid typing, and its satisfying clacky and poppy sound signature can certainly elevate your overall engagement with the keyboard. Therefore, consider your typing habits, whether you prefer an engaging heft or a feather-light touch, to make the best choice between these two exceptional switches.
