HMX FJ400 vs. Cherry MX Black
An in-depth look at the HMX FJ400 and the Cherry MX Black switches—which one is the best fit for you?
Overview
When choosing a mechanical keyboard, the type of switch can significantly impact your typing experience, and two popular options for gamers and typists alike are the HMX FJ400 and the Cherry MX Black, both of which are linear switches. The HMX FJ400 sits comfortably in the middle ground of the HMX Film switch lineup, boasting a well-rounded sound profile that appeals to those who prefer a balanced auditory feedback while typing. In contrast, the Cherry MX Black has been refined through Cherry's innovative Hyperglide tooling, delivering a classic, textured smoothness that many enthusiasts have come to love. Its low-pitched sound profile and stiff actuation make it a solid choice for individuals who prefer a more resistant typing experience. Both switches offer unique characteristics that cater to different preferences, making them worthwhile options to consider. However, let’s dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
When comparing the housing materials of the HMX FJ400 and the Cherry MX Black switches, we observe that both switches use nylon for their bottom housing, which contributes to a deep and full sound profile. This similarity is significant because the nylon's softer plastic qualities enable it to absorb sound, resulting in a muted, rounded audio experience when typing. However, the FJ400 distinguishes itself with a top housing made of POM, while the MX Black utilizes a classic nylon top housing. This difference in materials suggests that while both switches may produce similarly rich auditory feedback, the characteristics of that feedback are influenced by the specific properties of their respective top housings.
The POM housing of the FJ400 is designed to create a unique sound that leans towards a muted, deeper profile, differentiating it from the MX Black's nylon top housing. While both switches yield a pleasing typing experience, the sound profile of the FJ400 may be perceived as slightly less resonant compared to the fuller sound often produced by the MX Black's nylon top. The combination of POM on top for the FJ400 and nylon on the MX Black means that the sound generated when releasing a key will differ; the FJ400 may provide a more distinct and deeper release tone, while the MX Black's nylon is likely to yield a more traditional sound profile recognizable in many mechanical keyboards.
Ultimately, despite their differences, both the HMX FJ400 and Cherry MX Black switches capitalize on the advantages of their housing materials to deliver an engaging typing experience. The nylon bottom housings in both switches ensure that users enjoy the benefits of sound absorption and a rounded auditory feedback, while the distinct top housings influence the overall sound envelope produced during use. Whether using the deeper, unique sound of the FJ400 due to its POM top or the classic, traditional tones of the MX Black's nylon top, users can expect high-quality performance and a satisfying auditory experience from both switches.
Weight
When comparing the HMX FJ400 linear switch and the Cherry MX Black linear switch, a clear distinction emerges in their actuation and bottom out forces, with the FJ400 being the lighter option. The FJ400 has an actuation force of 50 grams and a bottom out force of 58 grams, making it suitable for users who prefer a medium feel for prolonged typing or gaming sessions. In contrast, the Cherry MX Black requires a heavier actuation force of 60 grams and has a bottom out force of 80 grams, catering to those who enjoy a more substantial typing experience. This difference in weight illustrates that the FJ400’s lighter actuation force allows for easier key presses, while the MX Black’s heavier force may provide more tactile feedback for users who favor that sensation. Therefore, those seeking comfort and reduced fatigue over long periods might lean towards the HMX FJ400, while individuals desiring a firmer typing feel may opt for the Cherry MX Black.
Travel distance
The travel distance of the HMX FJ400 linear switch is 3.8 mm, while the Cherry MX Black linear switch has a travel distance of 4 mm. This means that the MX Black has a slightly longer travel distance compared to the HMX FJ400. For those who prioritize responsiveness, the shorter travel distance of the FJ400 may be preferable, as it allows for quicker actuation. In contrast, gamers and typists who appreciate a more substantial feel may find the MX Black's longer travel distance to provide a more satisfying tactile experience. Ultimately, choosing between these two switches will depend on individual preferences regarding the balance between speed and depth in key presses.

Typing experience
In terms of sound, the FJ400 is best known for its balanced sound profile, making it a versatile choice for various environments and typing preferences. It offers a pleasing auditory experience that sits comfortably between harsh and overly muted tones, providing a more refined typing experience than some other switches. In comparison, the Cherry MX Black switches deliver a low-pitched sound characterized by their bass-heavy and mellow tone. This creates a deeper, more substantial auditory response when typing, contributing to a satisfying sound that many users appreciate. Both switches can emit similar tonal qualities, but it’s important to remember that the sound can also be influenced by other aspects like the choice of keyboard plate and keycaps.
When assessing feel, the FJ400 offers a unique typing experience, appealing to those who seek a smooth and consistent actuation without significant friction. However, details about its exact tactile sensations are not provided. In contrast, the Cherry MX Black switches are well-known for their textured feel, creating a noticeable friction as you press the keys. This may appeal to users who enjoy a bit of resistance during typing, as well as the added weight, since the MX Black switches are classified as stiff. This means they require more force to actuate, which some typists find enhances their control and accuracy.
In conclusion, while both the HMX FJ400 and Cherry MX Black switches provide distinct auditory and tactile experiences, the FJ400 is more balanced in sound, while the MX Black is noted for its deep tone and textured feel. The FJ400 may cater to those preferring a smoother actuation, accommodating a wider range of typing styles, whereas the MX Black can offer a firmer and more tactile experience. Ultimately, your preference may come down to whether you prioritize a balanced sound and smooth feel or a deeper tone with a textured and stiff action. Each switch excels in its own right and can cater to different user preferences effectively.
Conclusion
In summary, the choice between the HMX FJ400 linear switch and the Cherry MX Black linear switch ultimately depends on your typing preferences and intended use. If you prefer a medium bottom-out force that's relatively easier to actuate, then the FJ400 may be the ideal option for you, particularly if you're looking for a balanced sound profile that isn’t too overwhelming. It’s an excellent choice for typists who appreciate a softer touch, and it may suit those who do a lot of typing or gaming, allowing for longer sessions without fatigue. On the other hand, if you prefer a heavier switch that delivers a textured and deep sound experience, the Cherry MX Black would be your best bet. Its 80 grams of actuation force makes it well-suited for users who favor a more deliberate, firm keystroke, which can provide added assurance against accidental presses – ideal for both gaming enthusiasts and those who type with force. Therefore, consider what feels best for your typing style; whether you lean towards the ease of the FJ400 or the robust nature of the MX Black will significantly influence your satisfaction with your keyboard. Ultimately, each switch has its unique characteristics, making it essential to choose one that aligns with your personal typing experience and preference.
