HMX FJ400 vs. Bsun Olive

Overview

When it comes to choosing the right mechanical keyboard switch, the distinctions between the HMX FJ400 and the Bsun Olive demonstrate how personal preference can guide users toward an ideal typing experience. The FJ400, a linear switch characterized by its balanced sound profile, offers a smooth and silent keystroke that appeals to gamers and typists seeking efficiency without a tactile bump. Its performance sits at a comfortable middle ground within the HMX Film switch lineup, making it a versatile choice for a variety of tasks. On the other hand, the Bsun Olive, known for its all-POM housing, delivers a rich, resonant sound coupled with a pronounced tactile feedback that many find invigorating during use. With its unique design and long pole stem, the Olive provides a satisfying auditory experience alongside its medium-weight resistance, making it particularly appealing for those who appreciate a tangible sensation while typing. Both switches serve distinct needs and preferences, from the smooth action of the FJ400 to the snappy, tactile feel of the Olive. However, let’s dive in a bit deeper beyond generalities so you can best decide on the right switch for you.

Housing materials

When comparing the housing materials of the HMX FJ400 and the Bsun Olive, one immediate commonality emerges: both switches utilize POM for their top housing. This shared material contributes to a sound profile that is described as "incredibly pleasing and unique," characterized by a deeper and more muted tonal quality. The use of POM in both switches implies that the auditory experience will be notably similar when engaging with the keypresses, particularly during the release phase. This means that users of either switch can expect a satisfying sound upon keystroke release, enhancing the overall typing experience with a consistent acoustic signature.

Diving deeper into the bottom housing, however, we find a distinct divergence between the two models. The FJ400 incorporates a nylon bottom housing, known for its classic properties that elicit a deeper and fuller sound profile. The softer nature of nylon allows it to absorb more sound, creating a rounder auditory experience that contrasts with the POM bottom housing of the Olive. The nylon's ability to dampen audio frequencies means that users of the FJ400 will likely notice a more pronounced plushness in the overall sound when bottoming out, a characteristic that is inherently different from the Olive.

Consequently, the overall typing experience and acoustic profile of the FJ400 and the Bsun Olive reflect their differing bottom housing materials. While both switches will deliver a similar sound upon key release due to their POM top housing, the FJ400's nylon bottom will create a richer and softer sound at the bottom-out point, as opposed to the more neutral tonal quality of the Olive's POM bottom housing. This differentiation suggests that while users can enjoy a consistent release sound, the tactile and auditory experience during the keystroke's low point will vary significantly, thereby influencing user preference based on the distinct characteristics offered by each switch's respective bottom housing.

Weight

When comparing the HMX FJ400 linear switch to the Bsun Olive tactile switch, there are notable differences in both actuation and bottom out forces. The FJ400 has an actuation force of 50 grams, which is slightly heavier than the Olive's actuation force of 45 grams. This means that users of the FJ400 may experience a more substantial push feel when typing, potentially making it more suitable for those who prefer a firmer typing experience. In terms of bottom out forces, the FJ400 tops out at 58 grams, while the Olive has a heavier bottom out force of 65 grams. This indicates that while the Olive may provide a satisfying tactile feedback as a medium-heavy switch, it ultimately requires more force to fully compress compared to the FJ400. Overall, those who favor lighter switches and longer typing sessions may gravitate toward the Olive, while those who appreciate a stronger resistance might prefer the FJ400 for its heavier bottom out feel.

Travel distance

The HMX FJ400 linear switch has a travel distance of 3.8 mm, while the Bsun Olive tactile switch features a shorter travel distance of 3.4 mm. This difference in travel distance highlights the contrasting user experiences offered by each switch. The FJ400, with its longer travel distance, may provide a more pronounced tactile feedback, which some users appreciate for a more traditional typing experience. On the other hand, the Olive's shorter travel distance allows for quicker actuations, making it potentially more appealing for gamers who value speed and responsiveness. Therefore, if you lean towards a heavier sensation and a deeper keystroke, the FJ400 would be the better choice, whereas if you prefer faster response times and a slightly more abrupt feel, the Bsun Olive would suit you best.

Typing experience

When comparing the sound profiles of the HMX FJ400 linear switch and the Bsun Olive tactile switch, the differences become quite apparent. The FJ400 is celebrated for its balanced sound profile, which offers a harmonious blend that isn’t too harsh or too muted, making it an excellent choice for those who prefer a subtle auditory presence while typing. In contrast, the Olive switch produces a particularly resonant and deep sound, attributed to its all-POM housing. This gives it a more pronounced auditory experience that may stand out even in a busy environment, providing satisfying feedback during use.

In terms of feel, the HMX FJ400 is recognized for its smooth linear action, though it lacks the tactile feedback that many typists seek. It provides a consistent experience without interruptions, which can be appealing for those who prefer fast and uninterrupted keystrokes. The Bsun Olive switch, however, is defined by its medium tactile feedback, labeled as "accented," which strikes a balance between being too subtle and overly tactile. Its invigorating nature and sharp feedback create an engaging typing experience, ensuring that each keypress feels responsive and satisfying thanks to its crisp tactile bump.

In conclusion, while both the HMX FJ400 and the Bsun Olive switches offer unique sensory experiences, they cater to different preferences. The FJ400's balanced sound and smooth, consistent feel make it suited for users looking for a straightforward, linear option without tactile distractions. Conversely, the Olive's rich sound and pronounced tactile feedback provide a more dynamic experience, ideal for those who enjoy the satisfying sensation of tactile switches. Depending on what you prioritize in a mechanical keyboard, either of these switches can deliver a fulfilling typing experience, albeit in different ways.

Conclusion

To conclude, your choice between the HMX FJ400 linear switch and the Bsun Olive tactile switch will largely depend on your personal preferences and typing needs. If you prioritize a smoother, more consistent keystroke, the FJ400 is an excellent choice, especially if you appreciate a balanced sound profile without strong tactile feedback. This switch is ideal for those who enjoy a quieter environment or prefer to type without the interruption of significant tactile bumps. On the other hand, if you're seeking a more dynamic typing experience with a pronounced tactile feel, the Bsun Olive is likely to serve you better. Its medium-heavy actuation force and invigorating, sharp feedback not only provide a satisfying tactile sensation but also create an immersive auditory experience thanks to its deep sound profile. Thus, consider the FJ400 for gaming or work that demands speed and fluidity, while the Olive switch may be better suited for typing tasks where you want to enjoy that tactile engagement and responsiveness.
