HMX FJ400 vs. Bsun Ragdoll
An in-depth look at the HMX FJ400 and the Bsun Ragdoll switches—which one is the best fit for you?
Overview
When comparing the HMX FJ400 and the Bsun Ragdoll, both linear switches offer distinct characteristics that cater to different user preferences. The FJ400 is celebrated for its balanced sound profile, making it an excellent choice for those who appreciate a more muted and refined auditory feedback while typing, offering a harmonious blend between tactile feedback and sound. On the other hand, the Bsun Ragdoll stands out with its Y3 stem design that ensures smooth keystrokes and a nylon-fiberglass bottom housing that generates a clacky sound, appealing to users who enjoy a more pronounced acoustic experience while typing or gaming. While both switches are designed for linear performance, their unique properties — the FJ400's balanced sound and the Ragdoll's clackiness — set them apart for different audiences. However, let's dive in a bit deeper beyond generalities so you can best decide on the optimal switch for your needs.

Housing materials
The housing materials of the HMX FJ400 and the Bsun Ragdoll present a fascinating comparison, particularly due to their differing top housing compositions. The FJ400 features a POM (Polyoxymethylene) top housing, which is known for its ability to generate a unique sound profile that leans toward deeper tones and relatively muted acoustics. This characteristic is attributed to POM's hard nature, which affects the sound produced during key releases, contributing to a sharper sound. In contrast, the Ragdoll uses a nylon top housing, a classic material celebrated for its softer composition that absorbs sound. This results in a deeper and fuller sound profile, producing a duller and rounder auditory experience when the keys are released. As such, while both housings provide rich sound diversity, they do so through different acoustical mechanics.
When we shift focus to the bottom housing materials, both the FJ400 and Ragdoll utilize nylon, which brings a consistent element to their overall sound profiles. The nature of nylon, a softer plastic, plays a pivotal role in shaping the bottom-out feel and sound for both switches. It absorbs sound more effectively than harder plastics, resulting in a warmer, fuller sound signature when the keys are bottomed out. The similarity in bottom housing material ensures that both switches maintain a comparable depth in acoustics during actuation, which could appeal to users who enjoy that round and muted auditory experience regardless of the differing top housing materials.
Ultimately, the differences in the top housing materials of the FJ400 and Ragdoll create a nuanced distinction in their sound profiles, while their shared nylon bottom housing ensures a consistent depth and fullness in sound during actuation. The POM top of the FJ400 delivers a more crisp and detachable sound release, whereas the nylon of the Ragdoll emphasizes absorption and softness in sound. This dual approach provides users with a nuanced typing experience; enthusiasts can appreciate the characteristics imparted by both top housing materials while still enjoying the reliable consistency afforded by the nylon bottoms. For those who may be looking for similar auditory results, they can largely find satisfaction in the overall tonal qualities provided by both switch designs.
Weight
When comparing the HMX FJ400 linear switch and the Bsun Ragdoll linear switch, notable differences in their actuation and bottom out forces emerge. The FJ400 has an actuation force of 50 grams and a bottom out force of 58 grams, making it a medium-weight option, which is suitable for those who appreciate a more substantial typing experience. In contrast, the Bsun Ragdoll features a lighter actuation force of 45 grams and a bottom out force of 52 grams, categorizing it as medium-light. This lighter weight can appeal to users who prefer to type or game for extended periods without fatigue. Consequently, the FJ400 is the heavier switch, ideal for those desiring a firmer feel when typing, while the Ragdoll’s lower forces may cater better to users seeking comfort during prolonged use. Overall, the differences in actuation and bottom out forces reveal how each switch targets varying preferences in typing experience.
Travel distance
The HMX FJ400 and the Bsun Ragdoll linear switches both have identical travel distances, each measuring 3.8 mm from the top to the bottom. This means that users can expect a similar tactile experience when pressing down on the keys of devices utilizing either switch, as both will provide the same depth before activation. Given their equal travel distances, users can achieve comparable results in terms of key press feel and feedback. Thus, there is no shorter or longer switch between the two; instead, they offer a unified performance in this regard.

Typing experience
In terms of sound, the HMX FJ400 linear switch is known for its balanced sound profile, providing a harmonious auditory experience that sits comfortably in the middle range of mechanical keyboard sounds. This means it won't overpower you with noise but still offers a satisfying tone when typing. Conversely, the Bsun Ragdoll linear switch is noted for its clacky sound, which is attributed to its nylon-fiberglass bottom housing. While the Ragdoll’s clackiness may be appealing to users who enjoy an auditory feedback during typing, it may not be for everyone, especially those who prefer a quieter experience. Both switches will produce sound differently depending on the keyboard they are in, as well as the choice of keycaps used.
When considering the feel of these switches, the FJ400 offers a smooth and cushioned typing experience, making it suitable for prolonged use without much finger fatigue. It aims to strike a balance that can appeal to a wide array of typists, providing a pleasing tactile response without any abrupt interruptions. The Ragdoll switch, on the other hand, features a Y3 stem that is designed for smooth travel, which enhances the tactile experience. This design encourages a seamless keystroke without any jarring feedback, catering well to those who appreciate a fluid typing motion, though it may provide less tactile information than some users might prefer.
In conclusion, both the HMX FJ400 and Bsun Ragdoll linear switches present unique auditory and tactile experiences that cater to different user preferences. The FJ400 delivers a balanced sound and a smooth feel, making it ideal for those seeking an all-around typing experience. In contrast, the Ragdoll's clacky sound and seamless travel may appeal to users looking for a more pronounced auditory response paired with a fluid keystroke. Ultimately, both switches offer beneficial qualities that can lead to satisfying typing experiences, and users may find that their choice can lead to similar results in enjoyment based on their individual preferences in sound and feel.
Conclusion
To conclude, your choice between the HMX FJ400 linear switch and the Bsun Ragdoll linear switch ultimately hinges on your preferences for actuation force, sound profile, and tactile experience. If you enjoy a balanced typing experience with a medium bottom-out force of 58 grams, the FJ400 is a solid choice that offers a versatile performance across various typing styles and tasks. Its balanced sound profile makes it suitable for both office environments and gaming scenarios without being overly distracting. On the other hand, if you favor a lighter touch, the 52-gram bottom-out force of the Ragdoll switch may be more comfortable, especially during extended typing sessions. The Ragdoll's smooth travel and clacky sound, attributed to its Y3 stem and nylon-fiberglass housing, can add an enjoyable auditory element to your typing experience. In essence, choose the FJ400 for a robust, all-around performance and the Ragdoll if you seek a lighter, acoustically vivid experience. Your personal typing style and environment will be key factors in making the best decision.
