Outemu Dustproof Red vs. HMX SU
An in-depth look at the Outemu Dustproof Red and the HMX SU switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, the Outemu Dustproof Red and the HMX SU offer unique characteristics that cater to different preferences among typists and gamers alike. The Outemu Dustproof Red is designed for those who appreciate a smooth, linear feel during typing without any tactile bumps or auditory feedback, making it ideal for a quieter workspace. On the other hand, the HMX SU stands out with its full PA12 housing and T5 stem, delivering a subtly deeper sound profile that appeals to users who enjoy a bit of acoustic feedback while maintaining the smoothness of a linear switch. While both switches share the linear classification, their distinct builds and sound profiles suggest differing user experiences—whether one seeks silence or a touch of character in their keystrokes. 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 Red and the HMX SU, a clear distinction emerges between their top housings. The Dustproof Red features a polycarbonate top housing, known for its stiffer composition, which results in a sharper, higher-pitched, and crisper sound profile. This property allows for a more resonant sound, especially beneficial when utilizing RGB lighting due to its translucence. In contrast, the HMX SU employs a nylon top housing, which is softer and absorbs sound more effectively. This leads to a deeper and fuller sound profile, producing a duller and rounder auditory experience. Ultimately, while both switches serve distinct sound aesthetics due to their top housing materials, the Dustproof Red leans towards clarity, whereas the HMX SU emphasizes a more muted tone.
The bottom housings of both switches, however, are made from nylon, which produces similar acoustic qualities. Both the Dustproof Red and the HMX SU benefit from this classic material, which contributes to a deeper and fuller sound profile characterized by a sound absorption quality that dampens higher frequencies. This shared use of nylon means that both switches will elicit a rounder bottom-out sound, creating a harmonious typing experience. Therefore, regardless of the differences in the top housings, users can expect a consistent performance rooted in the nylon bottom housing across both models.
In conclusion, while the Outemu Dustproof Red and the HMX SU differ in their top housing materials—with polycarbonate contributing clarity and nylon providing depth—they align in their use of nylon for the bottom housing. This similarity guarantees that users will achieve a fuller, standardized sound profile during key presses, balancing the overall auditory experience when typing. For those who value a mix of sharpness from the Dustproof Red's top housing with the rounded characteristics of the nylon bottom housing, this formulation allows for a unique yet complementary auditory landscape. Conversely, enthusiasts who prefer the muted depth of the HMX SU will also find satisfaction, thanks to the identical bottom housing.
Weight
When comparing the Outemu Dustproof Red linear switch to the HMX SU linear switch, there are notable differences in their bottom out forces. Both switches share the same actuation force of 45 grams, making them equally responsive when it comes to triggering a keystroke. However, the Outemu Dustproof Red features a bottom out force of 60 grams, which is heavier than the HMX SU's bottom out force of 50 grams. This means that while both switches require the same amount of force to begin a keystroke, the Dustproof Red provides a more substantial and heavier feel when bottoming out, making it suitable for users who prefer a firmer typing experience. In contrast, the HMX SU, with its lighter bottom out force, may be favored by those looking for a more comfortable, less tiring typing experience over extended periods. Thus, while both switches act similarly at the actuation point, the Dustproof Red is notably heavier overall.
Travel distance
The Outemu Dustproof Red linear switch features a travel distance of 4 mm, making it one of the more traditional options that some users find appealing for its hearty depth and tactile feedback. In contrast, the HMX SU linear switch has a shorter travel distance of 3.6 mm, which aligns with the growing trend among gamers who favor quicker response times. While the Dustproof Red provides a more substantial feel when pressed, the shorter travel distance of the SU allows for faster actuation, making it more responsive. Ultimately, if you're looking for a switch that offers a deeper press and a more deliberate feel, the Outemu Dustproof Red is the better choice, whereas the HMX SU could be ideal if you prioritize speed and efficiency in your key presses.

Typing experience
When comparing the sound profiles of the Outemu Dustproof Red linear switch and the HMX SU linear switch, there are notable contrasts. The Dustproof Red's sound characteristics are not specifically highlighted in any notable way, suggesting it may have a more neutral auditory profile or simply be less memorable compared to the SU. In contrast, the HMX SU switch features a subtle and relatively deep sound profile, which can appeal to users who prefer a richer acoustic experience without being overly loud. It's important to remember that the overall sound production of both switches can vary based on the choice of keyboard plate and keycaps used, potentially altering how each switch is perceived in a practical setting.
Regarding the tactile feel of these switches, the Dustproof Red is not accompanied by a specific description regarding its tactile response, indicating that users may find it to be consistent with typical linear switches that lack tactile bumps. On the other hand, the HMX SU switch has a reputation for providing a smooth feel due to its PA12 housing and T5 stem construction, which may contribute to a more fluid typing experience. This smoothness can enhance the overall user satisfaction for those who favor a linear switch without any tactile feedback or resistance.
In conclusion, while the Outemu Dustproof Red linear switch may lack distinctive qualities in both sound and feel, the HMX SU linear switch stands out with its deeper sound profile and smooth tactile experience. If you prefer a straightforward and consistent experience, the Dustproof Red could serve you well, though you may find the HMX SU to offer a more engaging auditory and tactile experience. Ultimately, both switches can suit different preferences, and depending on your specific keyboard setup, both could deliver a satisfying performance.
Conclusion
To conclude, your choice between the Outemu Dustproof Red linear switch and the HMX SU linear switch ultimately hinges on your preferences for key pressure and sound profile. If you prefer a medium bottom-out force of 60 grams, which can provide a satisfying tactile feedback and can be advantageous for those who type with more force, then the Dustproof Red may be the better fit for you. However, if you lean towards a lighter actuation force with a bottom-out force of just 50 grams, which can promote a faster and more responsive typing experience, the HMX SU is likely what you want. Furthermore, if you appreciate a subtle yet relatively deep sound profile, the HMX SU’s PA12 housing and T5 stem construction are noteworthy features that can enhance your overall typing experience. Ultimately, if you're looking for something that feels a bit firmer and prefers a standard sound profile while typing, the Dustproof Red might be more suitable. In contrast, choose the HMX SU for a lighter touch and a richer auditory experience. By considering these nuances, you can select the switch that aligns best with your typing style and sound preferences.
