HMX FJ400 vs. Cherry MX Brown
An in-depth look at the HMX FJ400 and the Cherry MX Brown switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, the choice between the HMX FJ400 and the Cherry MX Brown can significantly influence your typing experience. The FJ400, known for its middle-ground position in the HMX Film switch lineup, is a linear switch that offers a balanced sound profile, making it an excellent choice for users who prioritize smooth keypresses without tactile bumps. In contrast, the Cherry MX Brown presents a tactile experience characterized by a gentle tactile bump and low-pitched, subdued audio feedback. This switch appeals to those who appreciate a bit of texture in their typing and prefer a lighter actuation force. While the FJ400 excels in providing a seamless and quiet typing experience, the MX Brown caters to users who enjoy subtle feedback and a more traditional feel. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The housing materials of the HMX FJ400 and the Cherry MX Brown switches create unique sound profiles, but they exhibit notable differences in their compositions and effects. The top housing of the HMX FJ400 is made from POM (polyoxymethylene), which imparts an incredibly pleasing and unique sound signature. This material is characterized by its ability to produce a deeper and relatively more muted sound when typing or pressing the keys. In contrast, the Cherry MX Brown switch features a nylon top housing, which, while also contributing to a fuller sound, does so in a slightly different manner. Nylon's softer composition allows it to absorb sound more effectively than POM, resulting in a duller and rounder auditory experience when typing.
Examining the bottom housing of both switches reveals more similarities than differences. The HMX FJ400 utilizes nylon for its bottom housing, which, like the Cherry MX Brown, is recognized as a classic switch housing material. Both switches benefit from the acoustic dampening properties of nylon, which enhances the sound quality by producing a deeper and fuller sound profile. This shared use of nylon for the bottom housing in both switches means that when typing, users will experience a similar auditory sensation due to the material’s ability to absorb sound, creating a muted bottom-out sound that is pleasing to the ear.
Ultimately, the distinct combination of different top housing materials in the HMX FJ400 and Cherry MX Brown switches leads to varied experiences in terms of sound and feel. While the nylon bottom housing in both switches ensures a consistent depth and fullness to the sound profile, the POM top housing of the FJ400 contributes a unique tonal quality that differentiates it from the more classic nylon top found on the MX Brown. The result is that users can expect both switches to deliver satisfying typing experiences, but with a nuanced divergence in sound characteristics based on the interplay of their respective top and bottom housing materials. This variance highlights how a switch's design is pivotal in shaping the tactile experience and auditory feedback, catering to the preferences of different users.
Weight
The HMX FJ400 linear switch and the Cherry MX Brown tactile switch present notable differences in their actuation and bottom out forces. The FJ400 requires an actuation force of 50 grams and a bottom out force of 58 grams, making it a medium-weight option. In contrast, the Cherry MX Brown has a lighter actuation force of 45 grams and a bottom out force of 55 grams, categorizing it as medium-light. This difference means that users may find the FJ400 offers a more substantial typing experience due to its heavier resistance, suitable for those who prefer a firmer feel when typing. On the other hand, the lighter actuation of the MX Brown might appeal to those who type for extended periods or engage in prolonged gaming sessions, allowing for reduced strain. Ultimately, individuals should consider their preferences for weight and typing experience when choosing between these two switches.
Travel distance
The HMX FJ400 linear switch has a travel distance of 3.8 mm, while the Cherry MX Brown tactile switch features a slightly longer travel distance of 4.0 mm. This indicates that the FJ400 offers a shorter distance compared to the MX Brown. For gamers or users seeking quick response times, the FJ400 may be the more appealing option due to its shorter travel distance, which can lead to faster actuation. In contrast, the Cherry MX Brown, with its longer 4.0 mm travel, may be preferable for those who appreciate a more pronounced depth and a tactile feedback while typing, as its added distance can help avoid any abrupt endings. Ultimately, the choice between these two switches comes down to personal preference regarding responsiveness versus a more robust feel.

Typing experience
When it comes to sound, the HMX FJ400 linear switch is known for its balanced sound profile, which means it avoids overly high-pitched tones while not being overly muted either. This makes it a versatile choice suitable for various environments, whether you're working in a quiet office or gaming at home. On the other hand, the Cherry MX Brown switch produces a low-pitched sound, characterized by a bass-heavy, mellow tone that contributes to a discreet typing experience. Users of the MX Brown can expect a more subdued audio feedback compared to other switch types, contributing to a less intrusive typing sound, although it’s worth remembering that the overall sound may vary based on the keyboard's design and keycap materials.
In terms of feel, the FJ400 is often noted for its smooth and consistent actuation, providing a seamless typing experience without the additional texture or friction that can be found in certain other switches. Conversely, the Cherry MX Brown switch features a textured experience, giving users a gentle tactile bump that is both subtle and noticeable. The textured feedback can be particularly appreciated by typists and gamers looking for that satisfying tactile moment without any excessive resistance. While the FJ400 aims for a more linear and smooth typing sensation, the MX Brown’s tactile feedback offers a more engaging interaction with each keystroke.
In conclusion, both the HMX FJ400 and Cherry MX Brown switches have their own unique attributes that cater to different typing preferences. The FJ400 offers a balanced sound and smooth feel that appeals to users who prefer a more consistent keystroke experience, while the MX Brown provides a low-pitched sound profile with textured tactile feedback, appealing to those who enjoy a physical response to their typing. Ultimately, the choice between these two switches will depend on whether you prioritize a smooth experience or a tactile sensation in your typing.
Conclusion
To sum up, choosing between the HMX FJ400 linear switch and the Cherry MX Brown tactile switch ultimately depends on your personal preferences and typing style. If you prefer a smooth and quiet typing experience, the FJ400 may be the better choice, offering a balanced sound profile while delivering a medium bottom out force of 58 grams that caters to those who enjoy a slightly firmer feel without being overwhelming. This makes it suitable for both casual typing and gaming where rapid key presses are involved. On the other hand, if you value a tactile feel and a more subtle audio feedback, the Cherry MX Brown switch, with its 55 grams of bottom out force, brings a gentler experience complemented by its low-pitched sound. Its textured feel can enhance your typing accuracy, making it ideal for those who type for long periods or want to engage in both gaming and typing tasks, as the gentle bump can provide helpful tactile feedback without being too loud. Ultimately, your choice should reflect your specific needs for typing comfort, sound preference, and the type of activities you'll be using your keyboard for.
