HMX FJ400 vs. HMX Vintage Citrus
An in-depth look at the HMX FJ400 and the HMX Vintage Citrus switches—which one is the best fit for you?
Overview
When it comes to choosing the right mechanical keyboard switch, the HMX FJ400 and the HMX Vintage Citrus both present compelling options for users seeking linear switches. The FJ400 serves as the middle ground in HMX's Film switch lineup, providing a balanced sound profile that caters to both casual typists and gamers who value a harmonious auditory experience without the harshness of clicks. On the other hand, the Vintage Citrus switch is designed specifically for gamers, featuring an exceptionally low actuation force of just 1mm, which allows for rapid-fire inputs and responsiveness during intense gaming sessions. This switch also boasts a bright, clacky sound profile and a remarkably smooth push feel, contributing to an engaging typing experience. While the FJ400 emphasizes a versatile sound and feel ideal for a broader range of users, the Vintage Citrus prioritizes speed and tactile excitement for gamers. 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 HMX Vintage Citrus, we find that the top housing of the FJ400 is made from POM, while the Vintage Citrus utilizes nylon. The POM top housing of the FJ400 is known for creating an exceptionally pleasing sound profile, which leans toward a deeper and more muted tone. In contrast, the nylon top housing of the Vintage Citrus is a traditional choice, providing a similarly deeper and fuller sound due to the softer plastic's ability to absorb sound. Both materials contribute to a muted auditory experience, but the distinctive characteristics of POM offer a unique angle to the sound profile that sets it apart from the classic nylon.
Looking to the bottom housings, both the FJ400 and Vintage Citrus utilize nylon. This is significant because the nylon bottom housing enriches the overall typing experience by eliciting a deeper sound profile, a quality that both switch designs share. This similarity means that users can expect a comparable sound when the key is fully pressed down. The nylon's softer nature ensures that sound is absorbed rather than amplified, leading to a duller and rounder sound for both switches. Hence, the similarities in bottom housing materials play a crucial role in ensuring that users experience consistent acoustic qualities across both switch types.
However, it is crucial to note that the differing top housing materials may result in variations in the sound profile when releasing keys. The POM material in the FJ400, while contributing to a muted sound when pressed down, may deliver a different auditory experience upon key release compared to the nylon housing of the Vintage Citrus. Essentially, while the deeper and fuller sound is a shared characteristic, the unique properties of POM versus nylon at the top level create potential distinctions in sound experience, showcasing how both design elements can influence overall performance. In practice, users can expect similar acoustic results when pressing down on the keys, but subtle differences may emerge during the release.
Weight
The HMX FJ400 linear switch and the HMX Vintage Citrus linear switch exhibit differences in both actuation and bottom out forces, catering to varying user preferences. The FJ400 features an actuation force of 50 grams and a bottom out force of 58 grams, making it a medium-weight option. In contrast, the Vintage Citrus is lighter, with an actuation force of 48 grams and a bottom out force of 53 grams, categorizing it as medium-light. While both switches provide a relatively comfortable typing experience, the Vintage Citrus's lower forces may appeal to users seeking prolonged typing sessions without fatigue, whereas the FJ400's slightly heavier resistance offers a more substantial feel for those who prefer greater feedback. Thus, while both switches provide a unique typing experience, the Vintage Citrus is the lighter choice, while the FJ400 leans toward a heavier preference.
Travel distance
When comparing the travel distances of the HMX FJ400 linear switch and the HMX Vintage Citrus linear switch, an interesting distinction emerges. The FJ400 has a travel distance of 3.8 mm, while the Vintage Citrus features a shorter travel distance of 3 mm. This difference indicates that the FJ400 offers a more substantial keypress experience, which may appeal to users who enjoy a deeper feel and a more pronounced tactile response. On the other hand, the Vintage Citrus, with its shorter travel distance, caters to those who prefer quicker responsiveness, making it particularly suitable for gamers seeking faster reaction times. Ultimately, if you lean towards a more abrupt feel for rapid engagements, the Vintage Citrus would be the better choice, while the FJ400's longer travel distance would satisfy those who appreciate a more hearty keypress.

Typing experience
In terms of sound, the HMX FJ400 presents a balanced auditory profile, delivering a subtle yet satisfying sound that fits well in a variety of environments. This makes it a versatile choice for both office and gaming setups. On the other hand, the HMX Vintage Citrus switch offers a bright and clacky sound profile that is unmistakably louder and more pronounced. This characteristic can enhance the auditory experience, particularly during intense gaming sessions where rapid key presses are common. However, it's important to remember that the sound experience can vary significantly based on the choice of keyboard and keycaps, so individual preferences may play a substantial role in the final outcome.
When it comes to feel, the FJ400 is designed to provide a smooth and consistent keystroke, offering a middle-ground experience that appeals to a wide audience. Its tactile response is reliable enough for both typing and gaming, lending itself well to extended use without causing fatigue. In contrast, the Vintage Citrus switch excels with its exceptionally low actuation force and smooth push, designed specifically for gamers who prioritize quick and agile inputs. The rapid actuation at just 1mm allows for a snappy keystroke that feels responsive, making it highly suitable for fast-paced gaming scenarios.
In conclusion, both the HMX FJ400 and Vintage Citrus switches have their own unique attributes that cater to different user preferences. The FJ400 provides a balanced sound and a smooth feel, making it an excellent all-around option for various tasks. Meanwhile, the Vintage Citrus stands out with its clacky sound and quick actuation, positioning it as an ideal choice for gamers seeking rapid responsiveness. Depending on your needs—whether you prioritize versatility or high-speed performance—either switch can deliver a satisfying experience, albeit in their distinct ways.
Conclusion
To conclude, the choice between the HMX FJ400 linear switch and the HMX Vintage Citrus linear switch largely depends on your personal preferences and intended use. If you prioritize a balanced sound profile and a slightly higher actuation force, the FJ400 may be your best bet, especially for typing or general use, where a medium actuation force lends itself to a satisfying tactile experience without being overly aggressive. On the other hand, if you're a gamer seeking rapid key presses and a smooth push feel, the Vintage Citrus switch is likely the better option, thanks to its low actuation force and quick response time at just 1mm. Its bright, clacky sound profile adds an extra layer of excitement to your gaming sessions, making it particularly appealing for fast-paced gameplay. Ultimately, your choice should reflect not just your typing habits but also the kind of sound and feel you enjoy in your mechanical keyboard.
