HMX FJ400 vs. Gateron G Pro 3.0 Yellow

Overview

When it comes to mechanical keyboard switches, the HMX FJ400 and Gateron G Pro 3.0 Yellow stand out as two compelling choices for enthusiasts seeking a linear switch experience. The FJ400 is celebrated for its balanced sound profile, making it a versatile option that appeals to users who prefer a more subdued auditory feedback while typing. It offers a smooth keypress that can be ideal for both gaming and typing, striking a fine balance between comfort and performance. On the other hand, the Gateron G Pro 3.0 Yellow is lauded for its budget-friendly excellence, boasting a higher-pitched clacky sound that adds character to the typing experience. This switch is designed for those who enjoy a more bouncy feel and resonate with a lively acoustic profile, making it particularly popular among gamers and typists alike. With differing acoustic signatures and tactile sensations, both switches cater to varying preferences and usage scenarios; 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 Gateron G Pro 3.0 Yellow switches, a notable contrast emerges in their top housing compositions. The FJ400 utilizes POM (Polyoxymethylene), which lends a uniquely muted and deeper sound profile, creating an overall more pleasing acoustic experience for users who prefer a less sharp tonal quality. In contrast, the G Pro 3.0 Yellow employs polycarbonate for its top housing, resulting in a crisper, higher-pitched sound that resonates clearly. This difference in material not only affects the auditory quality of each switch but also influences the aesthetic appeal, as polycarbonate's translucency enhances RGB lighting effects, making it a preferred choice for gamers and enthusiasts prioritizing visual effects in their keyboards.

Conversely, both the FJ400 and the G Pro 3.0 Yellow share the same bottom housing material: nylon. This material is celebrated for its ability to produce a deeper and fuller sound due to its softer composition, which effectively absorbs sound waves as they resonate within the switch. As a result, both switches share similarities in their bottom-out sound and overall acoustics derived from the nylon, reinforcing the classic feel associated with mechanical switches. While the sound profiles of the two switches differ due to their distinct top housings, the nylon bottom housing ensures a consistent depth in the auditory experience when the keys are pressed.

Ultimately, the interaction between the top and bottom housing materials of both switches exemplifies the importance of engineering in switch design. For the FJ400, the muted qualities of the POM top housing and the rich sound from the nylon bottom combine to create a unique typing experience. Meanwhile, the sharper polycarbonate top housing of the G Pro 3.0 Yellow, paired with the softer nylon bottom, results in a distinctly different soundscape without sacrificing deep bass tones. Users who appreciate the acoustic properties of mechanical switches will find that these two models, while differing in top housing materials, can still deliver a gratifying yet diverse tactile experience based on the unique contributions of both top and bottom housings.

Weight

The HMX FJ400 linear switch and the Gateron G Pro 3.0 Yellow linear switch both feature the same actuation force of 50 grams, providing an equally responsive feel when it comes to registering keystrokes. However, they differ in their bottom out forces, with the FJ400 requiring 58 grams to fully depress, compared to the G Pro 3.0 Yellow's higher bottom out force of 67 grams. This difference indicates that while both switches are equally easy to activate, the G Pro 3.0 Yellow offers a heavier resistance when fully pressed down, appealing to users who prefer a more substantial feel in their typing experience. As a result, the FJ400 is the lighter option overall, which may be more suitable for those who type for longer periods or engage in extended gaming sessions, while the G Pro 3.0 Yellow caters to those who appreciate a firmer push.

Travel distance

When comparing the travel distance of the HMX FJ400 linear switch and the Gateron G Pro 3.0 Yellow linear switch, a clear difference emerges. The FJ400 has a travel distance of 3.8 mm, which is shorter than the G Pro 3.0 Yellow's travel distance of 4 mm. This means that if you're looking for a more responsive feel, the FJ400 might be preferable due to its shorter actuation. On the other hand, the G Pro 3.0 Yellow, with its longer travel distance, caters to those who appreciate a more substantial feedback with each keystroke. Ultimately, selecting between these two switches depends on whether you prioritize speed and immediacy or a sense of depth and stability in your typing experience.

Price comparison

Typing experience

In terms of sound, the HMX FJ400 linear switch is noted for its balanced sound profile, suggesting a moderate auditory experience that won't overpower or distract during typing sessions. This makes it a suitable choice for those who prefer a quieter, less intrusive switch. On the other hand, the Gateron G Pro 3.0 Yellow has a distinctly higher-pitched clacky sound that delivers a sharp and crisp auditory response. This switch is resonant, creating an immersive sound experience that some may find more engaging, particularly in situations where acoustic feedback enhances the typing experience. However, the sound produced by both switches can also be influenced by the keyboard's build and the type of keycaps used.

When it comes to feel, the FJ400's characteristics aren't specified, leaving us without a direct comparison for its tactile feedback and smoothness. In contrast, the G Pro 3.0 Yellow excels with its polished and creamy feel, providing a silky typing experience that glides effortlessly under the fingers. The smooth nature of its design allows for reduced friction, making typing more enjoyable and less fatiguing over extended periods. The creamy sensation attributed to the G Pro 3.0 Yellow switches can be particularly satisfying, enhancing overall user enjoyment.

In summary, while the HMX FJ400 offers a balanced auditory experience, the Gateron G Pro 3.0 Yellow delights with its high-pitched and resonant sound. The G Pro 3.0 Yellow also stands out with its polished and creamy feel, providing smooth and pleasurable keystrokes. If you're in search of an immersive and engaging auditory experience alongside a refined tactile feel, the Gateron G Pro 3.0 Yellow is likely the preferable option. However, if you seek a more subtle sound profile, the FJ400 will serve you well. Each of these switches caters to different preferences, and your ultimate choice will come down to the qualities that matter most to you.

Conclusion

To conclude, choosing between the HMX FJ400 linear switch and the Gateron G Pro 3.0 Yellow switch ultimately depends on your specific preferences and typing style. If you appreciate a balanced sound profile and a medium bottom out force of 58 grams that provides a comfortable typing experience without being too heavy, the FJ400 is an excellent choice for you. It's versatile and accommodates a wide range of typing tasks, making it suitable for both casual users and gamers alike. On the other hand, if you favor a more pronounced auditory feedback with a higher-pitched, clacky sound that enhances your typing experience, the G Pro 3.0 Yellow, with its medium-heavy 67 grams bottom out force, may be your ideal switch. Its polished and creamy feel offers a smooth and enjoyable keystroke experience, perfect for those who type frequently or enjoy gaming. Ultimately, you should consider what aspects are most important to you—be it sound, feel, or typing force—before making your decision.
