HMX FJ400 vs. Dareu Sky POM

Overview

When comparing mechanical keyboard switches, the HMX FJ400 and the Dareu Sky POM stand out as intriguing options in the linear switch category, each with its own unique characteristics. The FJ400 strikes a balanced sound profile, making it an excellent choice for users who prefer a neutral auditory experience while typing, appealing to gamers and typists alike who value a harmonious blend of performance and acoustics. On the other hand, the Dareu Sky POM excels with its fully POM construction, delivering a clacky sound that adds a layer of auditory satisfaction, and is renowned for its silky smoothness and gentle actuation force, making it ideal for those who seek a tactile delight in every keystroke without sacrificing quality. While both switches offer excellent attributes to enhance your typing experience, the decision ultimately hinges on personal preferences in sound and feel. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

The housing materials of the HMX FJ400 and Dareu Sky POM are closely aligned, particularly when it comes to the use of POM for the top housing and nylon for the bottom housing. Both switches feature POM material for the top housing, which significantly influences their sound profiles. This shared material results in a similar auditory experience characterized by a deeper, more muted sound. The use of POM not only enhances the overall acoustic quality but also contributes to a cohesive sound signature that both products can deliver, allowing users to enjoy a pleasing and unique auditory experience when typing.

When examining the bottom housing, both the FJ400 and Sky POM employ nylon, a classic material that contributes to a deeper and fuller sound profile. The properties of nylon as a softer plastic enable it to absorb sound more effectively than harder materials, resulting in a rounder and duller acoustic quality. Since the bottom housing's characteristics primarily influence the bottom-out sound and feel of the switch, both models share a sense of fullness and depth in sound, further bridging the similarity between them. Users can expect comparable tactile feedback and auditory response when engaging with either switch, enhancing their overall typing experience.

While the FJ400 and Dareu Sky POM utilize different brands and potentially subtle design variations, their housing materials fundamentally align in purpose and effect. The combination of POM in the top housing and nylon in the bottom housing leads to a nuanced control over the sound profile of the switch. Given that both models produce rich, resonant audio experiences as a result of these materials, users can anticipate similar acoustic outcomes regardless of their choice between the two. This synergy between the components of each switch ultimately reinforces their compatibility in delivering quality sound and feel for typists and gamers alike.

Weight

The HMX FJ400 linear switch and the Dareu Sky POM linear switch present distinct characteristics in terms of actuation force and bottom-out force. The FJ400 features a relatively medium actuation force of 50 grams, which may appeal to users seeking a balance between comfort and feedback during typing. In contrast, the Sky POM switch offers a lighter actuation force of 40 grams, potentially making it more suitable for those who prefer a softer touch that can facilitate longer typing sessions without fatigue. While the bottom-out force for the FJ400 is known at 58 grams, indicating a firmer press when fully engaged, the Sky POM's bottom-out force remains unavailable. If one were to consider the actuation force alone, the Sky POM switch would be the lighter option, while the FJ400 would be considered the heavier choice due to its higher actuation and bottom-out forces. For tactile feedback, those who prefer a heavier switch may gravitate towards the FJ400, while users looking for a lighter experience could favor the Sky POM, provided they can accept the lack of information on its bottom-out force.

Travel distance

Both the HMX FJ400 linear switch and the Dareu Sky POM linear switch feature an identical travel distance of 3.8 mm, meaning that users will experience the same amount of key press travel regardless of the switch chosen. With both switches having the same travel distance, they will provide similar feedback and responsiveness during typing or gaming sessions, ensuring a consistent experience. Consequently, users can select either switch based on other preferences, knowing that the actuation depth will feel the same across both options.

Price comparison

Typing experience

When it comes to sound, the HMX FJ400 linear switch offers a balanced sound profile that caters to those who appreciate a moderate auditory feedback while typing. This switch strikes a middle ground, allowing for a pleasant acoustic experience without being overly intrusive. In contrast, the Dareu Sky POM switch boasts a low-pitched, clacky sound that adds character to each keystroke. Its bass-heavy tone can provide a more immersive typing experience, creating a distinct auditory atmosphere that appeals to many users. Ultimately, both switches produce different sound qualities; however, the choice between a balanced or a clackier sound can greatly influence one's typing satisfaction, depending on personal preference and the surrounding environment.

In terms of feel, the FJ400 is characterized as a middle-ground option that suggests a smooth typing experience but lacks specific descriptors to give a complete picture. On the other hand, the Sky POM excels with its buttery, creamy, and silky feel. These attributes indicate a remarkably smooth keystroke experience that makes typing feel effortless. Users opting for the Sky POM can expect a delightful sensation, as each keystroke glides smoothly without unnecessary friction, providing a more luxurious feel compared to the relatively undefined feedback of the FJ400.

In summary, the choice between the HMX FJ400 and the Dareu Sky POM linear switches ultimately boils down to personal preference in both sound and feel. If you lean towards a balanced sound profile and a more generic feel, the FJ400 may be the right fit. Conversely, if you favor a unique, low-pitched clacky sound coupled with an exceptionally smooth and luxurious typing experience, the Sky POM would be an excellent choice. Both switches offer distinct qualities, ensuring that there is a suitable option regardless of your typing style or desired acoustic feedback.

Conclusion

To conclude, your choice between the HMX FJ400 linear switch and the Dareu Sky POM linear switch ultimately depends on your specific preferences for sound, feel, and typing style. If you appreciate a balanced sound profile alongside a moderate actuation force of 58 grams, the FJ400 is a solid choice, providing a more grounded keystroke experience that won’t overwhelm your typing session. Its medium resistance makes it versatile for both gaming and typing, catering well to those who prefer a traditional yet satisfying key feel. On the other hand, if you seek an exceptionally smooth and creamy typing experience with a lower-pitched sound profile, the Sky POM switch stands out for its buttery and silky keystrokes. Its design for premium quality at an accessible price point makes it especially appealing if you're after a more tactile and enjoyable typing experience, especially for prolonged use. Ultimately, consider the type of feedback and sound that resonates with you; whether you lean towards the balanced confidence of the FJ400 or the luxurious smoothness of the Sky POM, both switches offer distinct advantages tailored to different users.
