Outemu Dustproof Black vs. HMX SU

Overview

When exploring the realm of mechanical keyboard switches, two notable linear options often come to the forefront: the Outemu Dustproof Black and the HMX SU. The Dustproof Black switch, while lacking distinct features, offers a consistently smooth keystroke experience that many typists and gamers appreciate for its reliability. On the other hand, the HMX SU excels with its full PA12 housing and a T5 stem, delivering a unique, subtly deep sound profile that enhances the typing experience and adds a touch of sophistication. While both switches provide the benefits of linear action—characterized by a smooth press without tactile feedback—their construction and sound profiles can significantly influence user preference. To make an informed choice between these two switches, 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 Outemu Dustproof Black and the HMX SU, notable differences emerge in the composition of their top housings. The Dustproof Black utilizes polycarbonate, known for its stiffness and translucence, which results in a sharper and crisper sound profile that is enhanced under RGB lighting. This makes the Dustproof Black particularly appealing to users seeking an auditory experience that is both clear and resonant, as well as aesthetically pleasing. In contrast, the HMX SU employs nylon for its top housing, leading to a deeper, fuller sound profile due to nylon's softer characteristics. This material absorbs sound more effectively, creating a typographic experience that feels more rounded and subdued. Thus, while both switches can deliver an appealing auditory experience, the Dustproof Black shines with a vibrant clarity, while the HMX SU provides a more muted resonance.

As for the bottom housings, both switches utilize nylon, aligning their sound profiles in this respect. The use of nylon in both the Dustproof Black’s and HMX SU’s bottom housings results in a warmer, fuller sound that significantly influences the bottom-out experience when pressing down on the switch. The properties of nylon allow for greater sound absorption, providing a consistent typing feel across both switches. Consequently, users can expect a similar performance from both models when focusing on this aspect of their design. The connection between the designs reveals that, despite their differences in top housing materials, the bottom housing remains a shared trait, ensuring a consistent base for both auditory and tactile feedback.

In summary, the Outemu Dustproof Black and HMX SU encapsulate distinct auditory experiences through their differing top housing materials. The Dustproof Black's polycarbonate top housing offers crisp and vibrant sound qualities ideal for RGB applications, while the HMX SU's nylon top housing favors a deeper, more subdued auditory experience. However, since both switches feature nylon in their bottom housings, users will find a commonality in the fuller sound profile and tactile feedback when pressing down the keys. This blend of contrasting and complementary materials illustrates how the interplay of top and bottom housings can shape the overall user experience, resulting in unique yet comparable outcomes for enthusiasts.

Weight

When comparing the Outemu Dustproof Black linear switch and the HMX SU linear switch, there is a notable difference in both actuation and bottom out forces. The Dustproof Black requires a heavier actuation force of 60 grams and a bottom out force of 80 grams, making it a better option for those who prefer a substantial typing experience. In contrast, the HMX SU switch offers a significantly lighter actuation force of 45 grams and a bottom out force of 50 grams, which is more suitable for users looking for comfort during extended typing sessions or gaming. Consequently, the Outemu Dustproof Black is heavier, catering to those who value a strong push feel, while the HMX SU is lighter, appealing to those who prioritize ease of use. This distinction in force requirements highlights the different user experiences each switch offers.

Travel distance

When comparing the travel distances of the Outemu Dustproof Black linear switch and the HMX SU linear switch, the differences are notable. The Outemu Dustproof Black boasts a travel distance of 4 mm, which aligns with the traditional standard and offers a more substantial depth for typing. In contrast, the HMX SU comes in with a shorter travel distance of 3.6 mm, catering to those who favor quicker response times, particularly gamers who benefit from reduced actuation distances. While the Dustproof Black allows for a more tactile experience, the HMX SU provides a more rapid feedback mechanism. Therefore, if you prefer a deeper and more pronounced key press, the Outemu Dustproof Black is the better choice, whereas the HMX SU will appeal to users seeking a more responsive and swift typing experience.

Typing experience

In terms of sound, the Outemu Dustproof Black switch is not particularly notable for any specific characteristics, making it somewhat of an unknown in this regard. However, the HMX SU linear switch features a full PA12 housing paired with a T5 stem, creating a subtle yet relatively deep sound profile. While the Dustproof Black lacks a defined sound signature, the SU’s deeper sound can provide a more satisfying auditory experience, though that may still vary based on the keyboard build and keycap choice.

When considering feel, the Outemu Dustproof Black switch doesn’t have specific qualities highlighted in its description, so it remains a bit of a mystery. In contrast, the HMX SU linear switch offers a smooth linear feel, which is characteristic of well-designed linear switches. This smoothness allows for a seamless keypress without tactile bumps or clicks, potentially offering an enjoyable typing experience for those who prefer unhindered keystrokes.

In summary, while the Outemu Dustproof Black may not stand out in terms of sound or feel, the HMX SU linear switch provides a unique combination of a deep sound profile and a smooth linear typing experience. If you're looking for an enjoyable auditory and tactile experience, the SU switch would be a compelling choice, while the Dustproof Black may offer a more neutral approach.

Conclusion

To conclude, when deciding between the Outemu Dustproof Black linear switch and the HMX SU linear switch, consider your typing preferences and the context in which you'll be using your keyboard. If you have a preference for a heavier switch that requires more force to bottom out—like the Dustproof Black, which has an 80-gram actuation weight—you might find it satisfying for gaming or for firm tactile feedback while typing. However, you'll need to be prepared for a more demanding typing experience, as the sound profile of the Dustproof Black is not well-defined but tends towards a firmer feel without the unique acoustic characteristics of other switches. On the other hand, if you prefer a lighter feel, the HMX SU with its 50-gram bottoming out force may be more in line with your needs, providing a more effortless typing experience with a gentle, pleasant sound profile thanks to its full PA12 housing and T5 stem. In essence, choose the Outemu Dustproof Black if you seek a more resistant switch with significant feedback and don't mind a heavier press; opt for the HMX SU if you desire a smooth, lighter touch and a distinctive audio quality that enhances the overall typing experience.
