HMX FJ400 vs. Neo Lavender HE
An in-depth look at the HMX FJ400 and the Neo Lavender HE switches—which one is the best fit for you?
Overview
When it comes to choosing mechanical keyboard switches, enthusiasts often weigh the benefits of linear switches like the HMX FJ400 against innovative hall effect switches like the Neo Lavender HE. The FJ400 stands out in the HMX Film switch lineup, renowned for its balanced sound profile and smooth keystrokes, making it an excellent choice for users who favor a consistent typing experience without tactile feedback. In contrast, the Neo Lavender HE is praised for its clean, low sound, paired with unique magnetic technology that enhances responsiveness, particularly when used in Wooting keyboards, appealing to gamers and those seeking precise actuation. Both switches offer distinct advantages: the FJ400 provides predictable performance ideal for typing, while the Lavender HE delivers innovative feedback that caters to a high-performance gaming experience. However, let’s dive in a bit deeper beyond generalities so you can best decide on the switch that suits your needs.

Housing materials
When comparing the housing materials of the HMX FJ400 and the Neo Lavender HE, a notable distinction lies in their top housing components. The FJ400 features a POM (Polyoxymethylene) top housing, which produces a unique sound profile that is described as deeper and muted. This aspect contributes to a unique auditory experience, as POM is known for its rigidness, affecting the harmonic resonance of the keystrokes. In contrast, the Lavender HE incorporates a nylon top housing, well-regarded for its ability to deliver a rounder and fuller sound. Nylon's softer characteristics help absorb more sound, resulting in a more pleasant and softer auditory feedback when keys are released. The difference in these materials indicates that while both switches may produce satisfying sound profiles, the FJ400 leans toward a sharper, more defined auditory note compared to the Lavender HE's mellow and rounded tone.
Moving on to the bottom housing, the FJ400 also utilizes nylon, mirroring the Lavender HE's choice. Both switches opt for nylon in the bottom housing, which is a seasoned material in switch design known for its ability to generate a deep sound profile. This similarity underscores the fact that both switches will exhibit similar sound qualities at the point of bottoming out. When pressed, the nylon material absorbs sound effectively, ensuring that both the FJ400 and Lavender HE provide a deeper, more satisfying auditory cue upon key activation. This comparative uniformity in bottom housing denotes that, regardless of the differences seen in the top housings, the impact on the feel and sound when the key is fully pressed down will be notably harmonious.
Thus, while the FJ400 and Lavender HE exhibit different materials in their top housings—POM for the FJ400 and nylon for the Lavender HE—their commonality in the bottom housing curates a cohesive performance in terms of sound produced during a key press. This results in a perfectly split audio characteristic, where the soft, absorbed tones of the nylon provide a duller response at the bottom while the distinct properties of POM in the FJ400 add a crisp note upon release. Consequently, enthusiasts can enjoy a varied experience with each switch, utilizing the distinctive sourcing materials to generate an appealing typing experience reflective of their individual preferences.
Weight
The HMX FJ400 linear switch and the Neo Lavender HE hall effect switch present a notable contrast in both actuation and bottom out forces. The FJ400 requires an actuation force of 50 grams, with a bottom out force of 58 grams, positioning it within a medium range. In contrast, the Lavender HE boasts a lighter actuation force of 40 grams and a bottom out force of 50 grams, making it more suitable for users who prioritize ease of keystrokes for extended typing or gaming sessions. Consequently, the Lavender HE provides a softer touch, while the FJ400 offers a more substantial push feel, appealing to those who prefer heavier switches. Overall, those seeking a lighter experience should gravitate towards the Neo Lavender HE, while those who appreciate a stronger resistance may favor the HMX FJ400.
Travel distance
Both the HMX FJ400 linear switch and the Neo Lavender HE hall effect switch feature an identical travel distance of 3.8 mm, meaning they provide the same tactile feedback as you press down on a key. This similarity in travel distance ensures that users can expect comparable actuation and response when using either switch, yielding a similar typing experience. As a result, individuals who prefer one switch over the other can enjoy consistent performance without any noticeable difference in the depth of their keystrokes.

Typing experience
In terms of sound, the HMX FJ400 linear switch is recognized for its balanced sound profile, striking a harmonious middle ground within the HMX Film switch lineup. This allows it to produce an audible but not overwhelming sound, making it suitable for both casual typists and gamers alike. On the other hand, the Neo Lavender HE hall effect switch is noted for its clean and low sound, which distinguishes it in the realm of magnetic switches. While both switches offer distinctive sound characteristics, the actual audible experience will ultimately depend on the specific keyboard build and choice of keycaps, which can significantly alter how each switch resonates.
When considering the feel of these switches, the FJ400 provides a smooth experience typical of linear switches, ensuring that there are no tactile bumps throughout the keypress, which many users find refreshing for typing and gaming. Conversely, the Lavender HE switch, infused with hall effect technology, offers a unique feel that is typically described as consistent and precise, aligning well with those who enjoy linear switches yet are in search of something a bit different. Both switches aim to deliver a satisfying linear feel, appealing to users who prefer noiseless and straightforward key presses.
In summary, both the HMX FJ400 and Neo Lavender HE switches cater to linear switch enthusiasts but bring their unique signature qualities. The FJ400 offers a balanced sound profile and a smooth feel, making it versatile for various applications. In contrast, the Lavender HE stands out with its clean sound and precise feel, appealing to those in the magnetic switch realm. Ultimately, while both switches share similarities in being linear, their distinct characteristics introduce variety into the typing experience, making personal preference an important factor in choosing between them.
Conclusion
To conclude, choosing between the HMX FJ400 linear switch and the Neo Lavender HE hall effect switch depends largely on your personal preferences and typing style. If you prefer a medium bottom-out force that strikes a balance between tactile feedback and ease of use, the FJ400 is a great option. Its balanced sound profile makes it versatile for various environments, whether you’re gaming or typing at work, offering a satisfying and consistent experience. On the other hand, if you lean towards a lighter keypress and prefer a clean, low sound signature, the Lavender HE is the way to go. This switch not only offers a quicker response due to its lighter bottom-out force but also works exceptionally well with Wooting keyboards. In essence, select the FJ400 for a balanced feel and sound that fits a wide array of uses, and opt for the Lavender HE if you seek that lightweight sensation and unique auditory experience during your typing or gaming sessions.
