Outemu Black vs. HMX SU

Overview

When it comes to choosing a mechanical keyboard switch, the Outemu Black and the HMX SU offer distinct characteristics that cater to different preferences among typists and gamers. The Outemu Black is celebrated for its linear feel, providing a smooth keystroke with minimal resistance, which can enhance typing speed and reduce finger fatigue during long sessions. Conversely, the HMX SU also boasts a linear design but stands out with its full PA12 housing and T5 stem, delivering a subtle yet deep sound profile that may appeal to those who appreciate a more audible feedback without compromising the smoothness essential for efficient typing and gaming. While both switches prioritize a linear experience, the Outemu Black excels in a straightforward tactile response, while the HMX SU adds a layer of acoustic intrigue to the mix. 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 Black and the HMX SU, we observe a notable difference in their top housing compositions. The Outemu Black utilizes a polycarbonate top housing, which lends itself to a sharper, high-pitched, and crisper sound profile due to the material's stiffer properties. This translucency of polycarbonate not only enhances the aesthetic appeal of the switch, particularly for those who favor RGB lighting, but also contributes to a more resonant sound quality when typing. In contrast, the HMX SU features a nylon top housing, resulting in a deeper and fuller sound profile that is distinct from the Black’s offering. The softer characteristics of nylon absorb sound more effectively, providing a duller and rounder auditory experience, which can be preferable for users seeking a softer tactile feedback.

Interestingly, both switches share nylon as the material for their bottom housings, creating some consistency in auditory properties. The nylon bottom housing used in both the Outemu Black and the HMX SU serves to absorb sound, leading to a similar experience in the tactile feedback when bottoming out on the keys. In this respect, both switches will deliver a fuller typing experience, as the bottom housing significantly influences the overall sound profile. Despite the differences in the top housings, the shared nylon material in the bottom will bridge a connection between the two, ensuring that users can expect a similar, rounded sound effect when pressed down.

In essence, while the top housings of the Outemu Black and HMX SU create distinct sound profiles—crisp and high-pitched for the Black and deeper for the SU—their matching nylon bottom housings contribute to an overlapping auditory experience. Users can expect that although each switch may cater to different preferences based on the top housing material, the combined performance of nylon in the bottoms ensures a fuller sound when actuated. Thus, those looking for diversity in sound profiles between these two switches can find it through their choice of top housing while benefiting from the consistent sound characteristics provided by the nylon bottom housing in both switches.

Weight

When comparing the Outemu Black linear switch and the HMX SU linear switch, there is a noticeable difference in actuation and bottom out forces. The Outemu Black has an actuation force of 65 grams and a bottom out force of 82 grams, making it on the heavier side, which can provide a more substantial typing experience favored by those who prefer a stronger push feel. In contrast, the HMX SU features a significantly lighter actuation force of 45 grams and a bottom out force of 50 grams. This lighter design is ideal for extended typing sessions or gaming marathons, allowing for less fatigue. Ultimately, the choice between these switches boils down to personal preference: the heavier Outemu Black offers a more tactile sensation, while the lighter HMX SU promotes quicker and less strenuous typing.

Travel distance

The Outemu Black linear switch has a travel distance of 4 mm, while the HMX SU linear switch measures 3.6 mm. This means the Outemu Black switch offers a longer travel distance, providing a more pronounced keypress that may appeal to users who enjoy a deeper tactile experience. In contrast, the shorter 3.6 mm travel distance of the HMX SU switch caters to those who prefer quicker response times, making it particularly suitable for gamers seeking efficiency in their keystrokes. Ultimately, if you value a more substantial key feel, the Outemu Black would be the better option, while the HMX SU is ideal for those who prioritize swiftness and responsiveness in their typing or gaming.

Price comparison

Typing experience

When it comes to sound, the Outemu Black switch is known for its relatively undefined acoustic profile, which can often lead to a muted typing experience. In contrast, the HMX SU switch is characterized by a subtle yet deeper sound, thanks to its full PA12 housing and T5 stem. This design gives the SU switch a more refined auditory feedback, making it potentially more satisfying for typists who appreciate a softer sound. However, it's essential to remember that the overall sound experience of either switch will largely depend on the specific keyboard and keycap combination used.

In terms of feel, the Outemu Black switch provides a linear experience that is direct and smooth, which many gamers prefer for its consistency in actuation. On the other hand, the HMX SU switch also offers a linear feel, but with a bit more emphasis on the tactile sensation due to its construction. While both switches deliver a linear actuation, the SU’s unique design may enhance the overall typing experience for those in search of a more engaging touch.

Overall, both the Outemu Black and HMX SU linear switches cater to users looking for a smooth, uninterrupted typing experience. Although the Black may not stand out in sound or feel, its linear characteristics make it a solid choice for gaming. Meanwhile, the SU switch provides a more nuanced sound and potentially a slightly enhanced tactile feel. Ultimately, your selection may depend on personal preference, but either switch can serve well in a mechanical keyboard setup.

Conclusion

To conclude, your choice between the Outemu Black and the HMX SU linear switches should be guided by your personal preferences for actuation force, sound profile, and overall typing experience. If you prefer a heavier key press that provides solid feedback and you are aiming for a more robust feel in your typing, the Outemu Black, with its 82 grams of bottom-out force, would be a suitable choice. It is ideal for those who enjoy a more tactile, forceful experience, especially if you tend to type or game vigorously. On the other hand, if you lean towards a lighter touch and desire a smoother action with a more subtle sound, the HMX SU, with its lighter 50 grams bottom-out force, will better suit your needs. The PA12 housing and T5 stem of the SU also offer an appealing acoustic experience, making it a great option for quiet environments or for those who appreciate a deeper sound profile. Ultimately, your decision should reflect how you interact with your keyboard—whether for long typing sessions, gaming marathons, or a mix of both—so consider your typing style closely to find the switch that enhances your overall experience.
