HMX FJ400 vs. Gateron G Pro 3.0 Brown
An in-depth look at the HMX FJ400 and the Gateron G Pro 3.0 Brown switches—which one is the best fit for you?
Overview
When it comes to choosing the right mechanical keyboard switches, preferences can often sway between the smoothness of linear switches and the tactile feedback of tactile switches. The HMX FJ400 is a linear switch that stands out in the HMX Film switch lineup as a balanced option, providing a consistent keystroke without the tactile bump, ideal for those who prioritize fluidity and speed in their typing experience. Alternatively, the Gateron G Pro 3.0 Brown offers a delightful tactile sensation, making it perfect for users who enjoy a subtle feedback with each keystroke while still benefiting from a price-friendly solution. These switches not only cater to different typing styles but also enhance the overall experience with features like the G Pro Brown's frosted light diffuser for vibrant RGB lighting. 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 Gateron G Pro 3.0 Brown present a fascinating juxtaposition that influences the overall sound and feel of the switches. The FJ400 features a top housing made from POM (Polyoxymethylene), which is known for producing a unique, deeper, and more muted sound profile. This characteristic is attributed to POM's construction, which absorbs some of the vibrations during key presses, softening the audible pop of bottoming out. In contrast, the G Pro 3.0 Brown utilizes polycarbonate for its top housing, which produces a sharper and more resonant sound due to its relatively stiffer nature. This discrepancy in materials means that the keypress experiences will differ significantly, with the FJ400 offering a more subdued auditory experience compared to the more pronounced and crisp sounds generated by the G Pro 3.0 Brown.
Both switches feature nylon for their bottom housings, creating a commonality that influences the sound on key bottoming out. Nylon, characterized as a classic material for switch construction, provides a softer touch and absorbs sound more effectively than harder plastics. Therefore, both the FJ400 and G Pro 3.0 Brown will elicit a deeper and fuller sound profile during key presses, thanks to this shared material base. The nylon bottom housing's ability to produce a rounder sound emphasizes the similarities between the two switches in terms of the bottom-out feel. While the top housing of each switch differentiates their auditory characteristics, the nylon bottoms create consistency in their sound when keys are fully pressed down.
Ultimately, the combined effects of the differing top housings and common bottom housing material highlight how the overall experience of using these switches can vary. The contrasting qualities of POM and polycarbonate in the top housings dictate the sound when releasing a key, while the shared nylon bottoms equalize the experiences during key presses. Users can expect a pronounced auditory experience from the G Pro 3.0 Brown, associated with a clearer, higher-pitched tone, while the FJ400 leans toward a fuller and richer sound profile. Those looking for a hybrid experience can expect somewhat similar results from the switches during the actuation phase due to the nylon material, yet the overall sound signature will remain distinct due to the different top housing materials.
Weight
When comparing the HMX FJ400 linear switch and the Gateron G Pro 3.0 Brown tactile switch, we observe distinct differences in actuation and bottom out forces. The FJ400 has an actuation force of 50 grams and a bottom out force of 58 grams, making it the lighter option of the two. In contrast, the G Pro 3.0 Brown requires a slightly heavier actuation force of 55 grams and bottoms out at 63 grams. This means that the Brown switch provides a more substantial push feel, which can be preferable for those who enjoy a firmer typing experience. Both switches fall under the medium category in terms of weight; however, the FJ400's lighter actuation force may make it more suitable for extended typing or gaming sessions, while the G Pro 3.0 Brown's heavier forces could offer a more tactile feedback to users who favor a stronger keystroke.
Travel distance
When comparing the travel distances of the HMX FJ400 linear switch and the Gateron G Pro 3.0 Brown tactile switch, we find that the FJ400 has a travel distance of 3.8 mm, while the G Pro 3.0 Brown features a slightly longer travel distance of 4 mm. This means that the FJ400 is the shorter option, favoring those who might prefer a more responsive feel during key presses, as shorter travel distances are often associated with quicker response times—a vital aspect for gaming. Conversely, the G Pro 3.0 Brown, with its longer 4 mm travel distance, may appeal to users who enjoy a deeper tactile feedback, which can provide a more satisfying typing experience. Therefore, depending on individual preferences for responsiveness versus depth, one might choose the FJ400 for snappier actions or the G Pro 3.0 Brown for a more traditional feel.

Typing experience
The sound profile of the HMX FJ400 linear switch is characterized as balanced, making it an excellent choice for those who prefer a more neutral auditory experience while typing. This balanced sound can create a pleasant acoustic environment without drawing too much attention or causing disruption. In contrast, the Gateron G Pro 3.0 Brown switch produces a medium-high pitch sound that delivers satisfying auditory feedback. This sound is likely to please those who appreciate the subtle click associated with tactile switches, making for an engaging typing experience. While both switches offer distinct sound qualities, the ultimate perception will also depend on factors such as the keyboard assembly and keycap choice.
Regarding feel, the FJ400 is known for providing a smooth keypress without any tactile bump, allowing for effortless transitions between keystrokes, which is ideal for fast typing and gaming. On the other hand, the G Pro 3.0 Brown exhibits a gentle tactile bump, which delivers essential feedback without being intrusive. Its easy-to-press nature ensures that the keys require minimal force, promoting comfort and reducing fatigue during lengthy typing sessions. The G Pro Brown also features a stepped feel, allowing users to experience a distinct actuation without overwhelming resistance. Overall, while both switches offer their unique sensations, those preferring a linear, uninterrupted feel might gravitate towards the FJ400, whereas the G Pro Brown provides a mild tactile experience that can enhance engagement with each keystroke.
In conclusion, the HMX FJ400 linear switch and the Gateron G Pro 3.0 Brown tactile switch both offer unique auditory and tactile characteristics that can cater to different preferences. The FJ400's balanced sound and smooth feel make it suitable for users who value a straightforward typing experience, while the G Pro Brown's pleasant auditory feedback and gentle tactile bump may appeal more to those who enjoy a bit of texture in their keystrokes. Ultimately, individuals will need to consider their typing style and preferences in sound and feel to determine which switch aligns best with their needs.
Conclusion
To conclude, the choice between the HMX FJ400 linear switch and the Gateron G Pro 3.0 Brown tactile switch ultimately depends on your typing preferences and the experience you seek from your mechanical keyboard. If you value a smooth and uninterrupted keystroke with a balanced sound profile, the FJ400 would be an ideal option. Its medium bottom-out force of 58 grams allows for a pleasant typing experience without overwhelming resistance, making it suitable for both typing and gaming. However, if you prefer a tactile feedback that enhances your typing experience, the G Pro 3.0 Brown is worth considering. With its mild tactile bump and slightly higher bottom-out force of 63 grams, this switch offers a gentle yet noticeable cue, perfect for those who enjoy the sensation of knowing when a key has been activated without being overly disruptive. Additionally, if you're a fan of RGB lighting, the G Pro Brown’s frosted light diffuser provides an appealing aesthetic for your keyboard. In essence, choose the FJ400 for a smoother, linear feel and the G Pro 3.0 Brown for a satisfying tactile experience; both switches cater to different types of users while still providing quality at an approachable price point.
