HMX FJ400 vs. Outemu Blue Jade
An in-depth look at the HMX FJ400 and the Outemu Blue Jade switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, the choice between the HMX FJ400 and the Outemu Blue Jade highlights a fundamental distinction in user preference: linear versus clicky. The HMX FJ400, known for its balanced sound profile, offers a smooth keystroke that minimizes audible feedback, making it an excellent option for those who value a quieter typing experience, whether in an office setting or during late-night gaming sessions. In contrast, the Outemu Blue Jade is a clicky switch that provides satisfying auditory feedback with each press, appealing to typists who enjoy the tactile sensation and distinctive sound that can enhance their typing experience. While the FJ400 excels in delivering a seamless and unobtrusive typing rhythm, the Blue Jade invites an engaging and immersive interaction with every keystroke. However, let’s dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The HMX FJ400 and the Outemu Blue Jade switches use differing materials for their top housing, with the FJ400 featuring a POM (Polyoxymethylene) top and the Blue Jade utilizing nylon. The POM top housing of the FJ400 contributes to a unique sound profile that leans toward the deeper and more muted side. This characteristic allows for a distinct auditory experience that some users may find more satisfying due to its unique tonal quality. In contrast, the Blue Jade's nylon top housing is hailed for its classic appeal, offering a deeper and fuller sound due to nylon's sound-absorbing properties. While both switches aim for a rich sound profile, the fundamental differences in their top housing materials create varied auditory experiences that may cater to different preferences.
On the other hand, both switches utilize nylon for their bottom housing, which is a significant commonality between the FJ400 and the Blue Jade. This shared material enhances the deeper and fuller sound profile inherent to both switches. Nylon's softer nature leads to better sound absorption, resulting in a duller and rounder sound signature regardless of the top housing differences. When it comes to actuating the switches, users will experience the benefits of the nylon bottom housing, which primarily influences the bottom-out sound and feel. This commonality suggests that users familiar with nylon's characteristics will notice similarities in the auditory experience when bottoming out on either switch.
In summary, while the HMX FJ400 and Outemu Blue Jade switches differ in their top housing materials—POM versus nylon—they share the same material for their bottom housing, contributing to a cohesive sound profile. The POM top housing's unique sound gives the FJ400 a distinct auditory flair, while the nylon top housing of the Blue Jade offers a classic richness. Ultimately, users will find that despite the variances in the top housing, both switches are capable of delivering similar sound qualities upon bottoming out, thanks to their nylon-infused bottom housings. This enables a shared acoustic experience, bridging the gap created by their top housing differences.
Weight
When comparing the actuation force and bottom out force of the HMX FJ400 linear switch and the Outemu Blue Jade clicky switch, we find some similarities and differences worth noting. Both switches have the same actuation force of 50 grams, which means users will experience a consistent keystroke trigger across both switches. However, the bottom out forces differ, with the FJ400 at 58 grams and the Blue Jade at a heavier 65 grams. This means that while both switches require the same force to register a keystroke, the Blue Jade offers a more pronounced pushback when fully pressed down, which might appeal to those who prefer a more substantial typing experience. As such, the FJ400 is the lighter option overall, making it more suitable for extended typing sessions, whereas the Blue Jade caters to users who favor a heavier and more tactile feel when typing.
Travel distance
When comparing the travel distances of the HMX FJ400 linear switch and the Outemu Blue Jade clicky switch, there's a notable difference to consider. The FJ400 features a travel distance of 3.8 mm, while the Blue Jade comes in at 4 mm. This makes the FJ400 the shorter of the two options, catering to those who prefer a more responsive feel, which is often favored by gamers seeking quick actuation. Conversely, the Blue Jade's longer travel distance may appeal to users who enjoy a more substantial keystroke, providing a satisfying depth to their typing experience. Ultimately, if you prefer faster response times, you'll likely find the FJ400’s shorter travel distance more suitable, whereas those who value a more pronounced keystroke would appreciate the Blue Jade's additional 0.2 mm.

Typing experience
When it comes to sound, the HMX FJ400 linear switch offers a balanced sound profile, making it versatile for various typing environments. This means it provides a subtle auditory experience without being overly quiet or loud, allowing for enjoyable yet unobtrusive typing. On the other hand, the Outemu Blue Jade clicky switch is known for its distinct clicking sound that adds a satisfying auditory feedback with each keystroke. This makes it feel more engaging for those who enjoy a pronounced sound while typing, especially in a mechanical keyboard setting. However, it’s important to remember that sound can be affected by the choice of keyboard and keycaps, which may modify the acoustic characteristics of either switch.
In terms of feel, the FJ400 is designed to deliver a smooth and consistent typing experience, characteristic of linear switches, which means that users can glide their fingers across the keys without any tactile bumps. This can lead to a faster typing experience without interruptions. In contrast, the Blue Jade provides tactile feedback with a noticeable bump that activates at the actuation point, offering a different sensation that can enhance typing accuracy for individuals who prefer to feel each key press. The tactile nature of the Blue Jade may appeal to users who enjoy the physical engagement of their typing experience, while the FJ400 caters to those who favor a seamless keystroke without distractions.
In summary, the HMX FJ400 linear switch stands out with its balanced sound and smooth feel, making it a solid choice for users wanting an unobtrusive and fluid typing experience. In comparison, the Outemu Blue Jade clicky switch is ideal for those who appreciate pronounced auditory feedback and tactile bumps, enhancing the tactile experience of typing. While both switches can offer satisfying performance, the choice between them ultimately depends on personal preference for sound and feel.
Conclusion
To conclude, the choice between the HMX FJ400 linear switch and the Outemu Blue Jade clicky switch fundamentally hinges on your personal preferences and typing style. If you prefer a smoother, quieter experience, the HMX FJ400, with its balanced sound profile and medium bottom-out force of 58 grams, is an excellent option. It's ideal for tasks that require heavy typing or gaming, allowing for a more fluid keystroke without the distraction of loud clicks. On the other hand, if you enjoy auditory feedback and a tactile sensation while typing, the Outemu Blue Jade's medium-heavy bottom-out force of 65 grams will satisfy your needs. Although its sound and feel characteristics are not specifically described, its clicky nature typically provides a satisfying feedback loop that many typists find enjoyable and nostalgic. Ultimately, your decision should reflect your desire for sound, feel, and typing intensity; if you crave a quiet, smooth experience, go for the FJ400, but if you thrive on tactile clicks, the Blue Jade will be your best bet.
