HMX FJ400 vs. Outemu Dustproof Brown
An in-depth look at the HMX FJ400 and the Outemu Dustproof Brown switches—which one is the best fit for you?
Overview
When choosing the right mechanical keyboard switch, the HMX FJ400 and the Outemu Dustproof Brown present unique characteristics that cater to different preferences and typing styles. The FJ400, recognized as a linear switch, is celebrated for its smooth keystrokes and quiet operation, making it an ideal choice for users who prioritize fast-paced gaming or a distraction-free typing environment. On the other hand, the Outemu Dustproof Brown, a tactile switch, provides a noticeable bump at the actuation point, offering a satisfying feedback that many typists appreciate for the enhanced writing experience. While the FJ400 is perfect for those seeking a balanced sound profile and swift key presses, the Dustproof Brown's design is tailored for users who enjoy tactile responses and may find comfort in the audible click. 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 Outemu Dustproof Brown, the most distinct difference lies in the composition of their top housings. The FJ400 features a top housing made of POM (Polyoxymethylene), which is known for creating a deeper and more muted sound profile. In contrast, the Dustproof Brown utilizes polycarbonate for its top housing, leading to a sharper and crisper sound due to the material's stiffer nature. This divergence in top housing materials significantly affects the auditory experience of the two switches; while the FJ400 is designed for a rich and subdued sound, the Dustproof Brown is poised to deliver a bright and resonant acoustics. However, should the FJ400 use transparent POM similar to polycarbonate, it might still achieve a resonant profile albeit to a lesser extent.
The similarity in bottom housing materials between both switches warrants comparison as well. Both the FJ400 and Dustproof Brown utilize nylon as their bottom housing material. Nylon's inherent softness is beneficial in providing a deeper and fuller sound profile for both switches, absorbing more sound and contributing to that rounder auditory experience. This commonality means that, despite their contrasting top housing materials, both switches ultimately share a foundational acoustic characteristic due to their nylon bottoms. Therefore, when pressed, both switches will likely produce a fuller, mellow sound from their bottom housings, yet still offer a different auditory experience upon release due to their unique top housings.
In summary, the housing materials of the HMX FJ400 and Outemu Dustproof Brown create a fascinating contrast that defines their sound profiles. While both switches benefit from the insulating and tonal qualities of nylon in their bottom housings, the POM and polycarbonate top housings delineate their character, leading to a divergence in the acoustic experience. Users seeking a more muted sound may gravitate toward the FJ400, while those in search of a sharper, more vibrant sound will likely be drawn to the Dustproof Brown. Despite these differences, the nylon bottom housing ensures that both switches maintain a certain depth and richness in sound, allowing them both to deliver enjoyable tactile experiences.
Weight
When comparing the HMX FJ400 linear switch and the Outemu Dustproof Brown tactile switch, notable differences emerge in their actuation and bottom out forces. The FJ400 features an actuation force of 50 grams and a bottom out force of 58 grams, while the Dustproof Brown has a slightly lighter actuation force of 45 grams but a heavier bottom out force of 65 grams. This makes the FJ400 switch a bit heavier overall, appealing to users who prefer a more substantial typing experience. On the other hand, the Outemu Dustproof Brown, with its lighter actuation force, can offer a more comfortable typing experience for extended sessions, despite its heavier bottom out force. Ultimately, choosing between these two switches comes down to personal preference, where the FJ400 leans towards those who enjoy a stronger tactile feedback while the Dustproof Brown may cater to those seeking a lighter touch.
Travel distance
When comparing the travel distance of the HMX FJ400 linear switch and the Outemu Dustproof Brown tactile switch, we see a notable difference. The FJ400 has a travel distance of 3.8 mm, while the Dustproof Brown features a travel distance of 4 mm. This means that the Dustproof Brown provides a longer travel distance, making it suitable for users who prefer a fuller typing experience with more pronounced feedback. On the other hand, the FJ400, with its shorter travel distance, caters to those who favor quicker response times, such as gamers who benefit from faster actuation. Therefore, if you prefer a more responsive feel, the FJ400 would be the better choice, whereas if you appreciate a deeper and more substantial keystroke, the Dustproof Brown would be preferred for its longer travel.

Typing experience
The sound profile of the HMX FJ400 linear switch is characterized as a balanced and muted acoustic experience, making it suitable for both quiet environments and louder settings where clack or click is not preferred. In contrast, the Outemu Dustproof Brown tactile switch does not have a well-defined auditory signature available for comparison. However, it’s important to remember that the sound produced by any switch can be significantly influenced by the keyboard's construction and the materials of the keycaps used, which means users may experience variations in sound quality across different setups.
Regarding the tactile feel of these switches, the FJ400 offers a smooth linear action, providing a consistent resistance throughout the key press without any tactile bump, allowing for swift typing without any interruptions. On the other hand, the Outemu Dustproof Brown switch features a tactile bump designed to provide feedback when the key is actuated, catering to those who appreciate a noticeable point of resistance. This tactile response can enhance the typing experience for users who prefer to feel when a key has been pressed, contrasting with the smoothness of the FJ400.
Overall, while the HMX FJ400 linear switch is known for its balanced sound profile and smooth linear feel, the Outemu Dustproof Brown remains less characterized in terms of sound but is recognized for its tactile feedback. If you seek an auditory experience, the FJ400 may provide a more predictable soundscape, whereas the Dustproof Brown may appeal to tactile enthusiasts looking for that engagement during typing. Ultimately, your preferences in sound and feel will guide your choice, and both switches can deliver satisfying results depending on your typing style and environment.
Conclusion
To conclude, your choice between the HMX FJ400 linear switch and the Outemu Dustproof Brown tactile switch ultimately hinges on your typing preferences and intended use. If you're seeking a smooth and linear experience with a balanced sound profile, the FJ400 might be your go-to option, especially due to its medium bottom-out force of 58 grams, which provides a comfortable typing experience without being overly demanding. This switch would be ideal if you favor rapid, uninterrupted keypresses for activities like gaming or fast-paced typing. Conversely, if you prefer a tactile feedback during your typing and don't mind the slightly heavier actuation force of 65 grams that the Dustproof Brown offers, then this switch may better suit your needs. The Dustproof Brown provides a distinct feel, which can enhance your typing experience with noticeable feedback on each keystroke, making it great for those who enjoy a more deliberate typing style. Ultimately, think about whether you value a smooth, linear response or a tactile sensation with your mechanical keyboard; your choice between these two switches should reflect that.
