HMX FJ400 vs. Outemu Dustproof Silent Ocean
An in-depth look at the HMX FJ400 and the Outemu Dustproof Silent Ocean switches—which one is the best fit for you?
Overview
When searching for the perfect mechanical keyboard switch, the choice often comes down to personal preference and specific use cases. The HMX FJ400, a linear switch, stands out for its balanced sound profile, making it an excellent option for users who enjoy a smooth typing experience without overly noisy keystrokes. In contrast, the Outemu Dustproof Silent Ocean, also a linear switch, promises a more tranquil ambiance with its added dustproof features, catering to those who prioritize a quieter environment, whether for work or gaming. While both switches provide the linear feel that many users prefer, the FJ400 may appeal to those looking for versatility and adaptability, whereas the Dustproof Silent Ocean is ideal for individuals seeking a serene typing experience without distraction. 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 HMX FJ400 and the Outemu Dustproof Silent Ocean switches, a distinct difference can be observed in their top housing materials. The FJ400 features a POM housing, which is known for producing a sound profile that is deeper and more muted, contributing to a rich auditory experience. In contrast, the Dustproof Silent Ocean's polycarbonate top housing delivers a sharper, higher-pitched sound that is crisper and more resonant. The rigidity of polycarbonate tends to create a sound layer that is more pronounced, especially beneficial for RGB lighting enthusiasts given its translucency. Consequently, while both switches provide high-quality sounds, their auditory characters diverge notably due to the contrasting properties of POM and polycarbonate.
Both switches utilize nylon for their bottom housing, which introduces an interesting similarity to their sound profiles. Nylon, as a softer plastic, is effective at absorbing sound and produces a deeper and fuller auditory experience. This characteristic is carried over into both models, meaning that while the top housing influences the higher ends of the sound spectrum, the underlying nylon base offers a robust foundation for the overall sound signature. Thus, it can be argued that despite the differences in the top housings, using nylon on the bottom ensures both switches share a common ground in producing rich, rounded sounds that many typists find appealing.
Ultimately, the combination of the differing top housings with the shared nylon bottom housing format establishes a contrast and similarity that can affect the user's typing experience. The POM top on the FJ400 may create a deeper and more muted resonance, while the polycarbonate top of the Outemu Dustproof Silent Ocean offers a brighter, crisper response. However, due to nylon's consistent influence on the bottom housing across both models, users might find that the profound fullness remains a shared trait, making both switches suitable for those who enjoy a multi-layered sound experience.
Weight
When comparing the HMX FJ400 linear switch and the Outemu Dustproof Silent Ocean linear switch, we see notable differences in their actuation and bottom out forces. The FJ400 has an actuation force of 50 grams, which is a bit heavier than the Dustproof Silent Ocean's actuation force of 45 grams. This means that the FJ400 may require slightly more force to trigger a keystroke, making it a better choice for users who prefer a more substantial typing experience. In terms of bottom out force, the FJ400 reaches 58 grams compared to the Ocean's 65 grams, indicating that the Dustproof Silent Ocean provides a slightly heavier feel when fully engaged. Consequently, for those who favor a lighter switch that allows for extended typing sessions without fatigue, the Outemu Dustproof Silent Ocean is the preferable option. However, for users who enjoy a firmer keystroke and bottom-out experience, the FJ400 may be the right choice, despite its heavier actuation force. Overall, the Dustproof Silent Ocean is the lighter switch in terms of actuation, while both switches exhibit a medium to medium-heavy feel in their respective bottom out forces.
Travel distance
When comparing the travel distances of the HMX FJ400 linear switch and the Outemu Dustproof Silent Ocean linear switch, a clear distinction emerges. The FJ400 has a travel distance of 3.8 mm, making it the longer option, while the Dustproof Silent Ocean features a shorter travel distance of 3.3 mm. This difference in travel distance can significantly affect the feel and responsiveness of each switch. Gamers, who often prefer shorter travel distances for quicker response times, may find the Dustproof Silent Ocean more appealing. Conversely, those who favor a more substantial keypress might lean towards the FJ400 due to its deeper travel. Ultimately, the choice between these two switches will depend on individual preferences regarding keypress feel and responsiveness.

Typing experience
In terms of sound, the HMX FJ400 linear switch is recognized for its balanced auditory profile, providing a moderate level of noise that many users find agreeable for both typing and gaming. This balanced sound can be influenced by the keyboard's construction and the choice of keycaps used, allowing for some variability in the overall auditory experience. On the other hand, the Outemu Dustproof Silent Ocean switch doesn't have specific sound characteristics noted, which leaves a gap in comparison. However, due to its designation as a "silent" switch, one can anticipate a quieter operation, ideal for environments where sound is a consideration.
When it comes to feel, the FJ400 is often praised for its smooth actuation, offering a satisfying experience for users who appreciate a linear switch with a consistent resistance throughout the key press. This makes it suitable for extended typing sessions and rapid gaming actions. The Dustproof Silent Ocean's tactile sensation isn't explicitly described, meaning we cannot draw a direct comparison here. However, silent linear switches generally maintain a smooth actuation as well, likely providing a pleasant typing experience similar to that of the FJ400.
In conclusion, both the HMX FJ400 and the Outemu Dustproof Silent Ocean linear switches each bring unique qualities to the table, particularly in sound and feel. While the FJ400 offers a balanced sound profile and a smooth feel that many users enjoy, the Silent Ocean likely provides a quieter experience due to its silent nature, although its specific characteristics remain unclear. Users looking for balanced sound and feel will likely find satisfaction with the FJ400, while those aiming for a muted experience with a similar smooth actuation can consider the Dustproof Silent Ocean as an alternative.
Conclusion
To conclude, your choice between the HMX FJ400 linear switch and the Outemu Dustproof Silent Ocean linear switch ultimately depends on your typing preferences and environment. If you prefer a switch that offers a balanced sound profile and a smooth feel with a moderate actuation force, the FJ400 is ideal for you. It provides an enjoyable typing experience that suits both casual typing and gaming without being overly noisy, making it a suitable option for a variety of settings, including quieter shared workspaces. On the other hand, if you appreciate a slightly heavier switch that offers enhanced tactile feedback and durability, the Outemu Dustproof Silent Ocean might be your best bet. Its medium-heavy actuation force ensures you have a more pronounced response with each keystroke, which can be great for those who enjoy a firmer typing experience and might be in environments where dampening sound is crucial — such as libraries or offices. In summary, consider the FJ400 for a balanced, versatile experience and the Dustproof Silent Ocean for a firmer, quieter feel. Your choice ultimately hinges on your personal preferences regarding sound, feel, and the environments in which you will be using your keyboard.
