HMX FJ400 vs. Outemu Black
An in-depth look at the HMX FJ400 and the Outemu Black switches—which one is the best fit for you?
Overview
When selecting the ideal mechanical keyboard switch for your typing and gaming preferences, it's crucial to consider the unique characteristics of each option. The HMX FJ400 is celebrated as a versatile choice within the HMX Film switch lineup, offering a balanced sound profile that caters to users who enjoy a mix of tactile feedback and smooth keystrokes. Its linear action makes it a popular choice among gamers who seek quick and uninterrupted key presses. On the other hand, the Outemu Black, also a linear switch, stands out for its higher actuation force, which provides a more deliberate pressing experience. This can be especially appealing to those who prefer a firmer key feel and are less prone to accidental presses while gaming or typing. Each switch presents its own benefits tailored to different use cases, enhancing overall user experience. 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 Black switches utilize different materials for their top housings, which significantly affects their overall sound profiles. The FJ400's top housing is made of POM (polyoxymethylene), known for producing a deeper, more muted sound. This sound characteristic is indicative of how POM effectively absorbs vibrations, resulting in a sound that is less sharp but more pleasant for users who enjoy a rounded auditory experience. In contrast, the Outemu Black features a polycarbonate top housing, which typically produces a higher-pitched and crisper sound profile due to polycarbonate's rigidity and ability to resonate more. Aesthetically, the transparency of polycarbonate allows for vibrant RGB lighting effects, appealing to users looking for both performance and visual flair in their switches.
When examining the bottom housings of both switches, they share the same material: nylon. This choice contributes to both switches' sound profiles, as nylon is renowned for its ability to absorb sound, leading to a deeper and fuller auditory experience. The impact of this material is particularly noticeable in the bottom-out sound and feel when typing, as nylon's softer composition dampens harsh noises and results in a more satisfying keystroke. Consequently, while the FJ400 achieves a unique sound profile through the combination of its POM top housing and nylon bottom housing, the Outemu Black benefits from the nylon base as well but contrasts with its sharper top housing.
In scenarios where the top and bottom housings are mismatched, as seen in these two switches, the qualities of each material will manifest at different stages of keypress. The FJ400, with its POM top, offers a softer release sound when the key is lifted, while the Outemu Black emphasizes clarity and brightness due to its polycarbonate top. However, both switches leverage their nylon bottom housing to create depth in sound, ensuring that despite their differences in upper housing, users seeking similar auditory experiences can find satisfaction in the fuller sounds produced during keypresses. Ultimately, users may appreciate how both switches can offer distinct yet appealing sound profiles by balancing the unique acoustic characteristics of their component materials.
Weight
The HMX FJ400 linear switch and the Outemu Black linear switch exhibit notable differences in their actuation and bottom out forces. The FJ400 features a lighter actuation force of 50 grams and a bottom out force of 58 grams, making it ideal for those who prefer a medium weight for extended typing or gaming sessions. In contrast, the Outemu Black switch is designed with a heavier actuation force of 65 grams and a bottom out force of 82 grams, catering to users who appreciate a more substantial push feel while typing. Consequently, the FJ400 allows for more effortless keystrokes, which can be beneficial for prolonged usage, while the Outemu Black offers a firmer resistance that some users find satisfying and motivating. Therefore, based on these specifications, the HMX FJ400 is the lighter option, whereas the Outemu Black is the heavier switch, accommodating different user preferences effectively.
Travel distance
When comparing the travel distance of the HMX FJ400 linear switch and the Outemu Black linear switch, it is evident that the FJ400 has a shorter travel distance of 3.8 mm, while the Black switch has a slightly longer travel distance of 4 mm. The Black switch, with its traditional 4 mm travel distance, may appeal to users who enjoy a more substantial feel when typing, as it allows for a deeper keypress that can be more satisfying for some. Conversely, the FJ400’s 3.8 mm distance caters to those who prefer quicker response times, making it an advantageous choice for gamers looking for fast actuation. Thus, while the FJ400 offers a more responsive experience due to its shorter travel distance, the Outemu Black provides a heftier feel for those who appreciate greater depth in their key presses.

Typing experience
When it comes to sound, the HMX FJ400 linear switch offers a balanced sound profile, making it suitable for various typing environments. This neutrality allows it to fit seamlessly into both quiet and more active settings, ensuring that it doesn't stand out too much while still delivering a satisfying auditory feedback. On the other hand, the Outemu Black linear switch is less defined in its sound characteristics, which means that it might not offer the same consistency in auditory feedback. Due to this, it can present a more ambiguous experience depending on the configuration of your keyboard and the specific setup used.
In terms of feel, the FJ400 is recognized for its smooth and consistent linear action, providing a comfortable typing experience without any tactile bumps or interruptions. This switch is designed to enhance the sensation of fluidity, allowing for rapid and effortless key presses. The Outemu Black linear switch typically shares a reputation for a smooth key actuation as well, suggesting a similar experience in terms of tactile feedback. Therefore, both switches are great options for those looking to experience an unbroken flow while typing or gaming.
In conclusion, both the HMX FJ400 and the Outemu Black linear switches present appealing qualities in their sound and feel. While the FJ400 is noted for its balanced auditory profile and smooth actuation, the Outemu Black remains a more ambiguous option but does not fall short in delivering a pleasant experience either. Ultimately, if you favor a consistent sound and a fluid typing sensation, the FJ400 may be the better choice, but either switch can provide similar tactile results when matched with compatible boards and keycaps.
Conclusion
To sum up, when choosing between the HMX FJ400 linear switch and the Outemu Black linear switch, it largely depends on your typing preferences and the kind of experience you're looking for. If you appreciate a more balanced tactile experience with a moderate actuation force, the FJ400 is an excellent choice. Its medium bottom-out force of 58 grams strikes a nice balance, making it comfortable for extended typing sessions while offering a pleasant acoustic profile that suits various environments. On the other hand, if you prefer a firmer response and are accustomed to heavier switches, the Outemu Black, with its significant bottom-out force of 82 grams, allows for greater control and a more deliberate feel as you type. However, keep in mind that this heavier resistance can be tiring for some users over time. Ultimately, your decision should hinge on your typing style and comfort level; if you seek a versatile and balanced option, the FJ400 shines, while the Outemu Black caters to those who desire a sturdier and more robust feel.
