Cherry MX Silent Red vs. HMX SU
An in-depth look at the Cherry MX Silent Red and the HMX SU switches—which one is the best fit for you?
Overview
When choosing a mechanical keyboard switch, the Cherry MX Silent Red and the HMX SU linear switches present two compelling options tailored for different preferences. The Cherry MX Silent Red is renowned for its quiet operation, providing the smooth, uninterrupted keystrokes characteristic of linear switches while eliminating noise—a perfect choice for those who type in open office environments or share spaces with others. Its muted, thocky sound and textured feedback offer a unique tactile experience without the distraction of audible clicks. In contrast, the HMX SU is characterized by its robust PA12 housing and T5 stem, which contribute to a slightly deeper sound profile that still maintains a satisfying tactile experience. This switch can appeal to users looking for a more resonant typing sensation without the loud clacking of traditional switches. Both switches cater to users who appreciate linear feel but offer distinct sound and feedback experiences. However, let’s dive in a bit deeper beyond generalities so you can best decide on the perfect switch for you.

Housing materials
The Cherry MX Silent Red and the HMX SU both feature nylon as their primary housing material, both for the top and bottom housings. This shared choice of material means that users can expect similar auditory experiences when typing on either switch. Nylon, being a softer plastic, plays a crucial role in sound dampening, which is essential for users who prefer a quieter keyboard. The deeper and fuller sound profile generated by both switches arises from the way nylon absorbs more sound compared to harder plastics. Consequently, users can anticipate a duller and rounder auditory feedback when utilizing either switch, which is particularly beneficial in environments where noise levels need to be minimized.
Even though both switches use nylon for both the top and bottom housings, their construction and design nuances may result in slightly different tactile feedback or sound profiles. The impact of the bottom housing is typically more pronounced during keypresses, influencing the bottom-out sound and feel, while the top housing contributes more to the sound when releasing the keys. Since both switches are unified by this nylon design, any differences in user experience might stem less from the housing material itself and more from other design aspects such as the spring tension or switch actuation mechanisms. Therefore, although they share the same material characteristics, the full typing experience might still vary depending on these additional factors.
Overall, the identical use of nylon in both the Cherry MX Silent Red and HMX SU leads to comparable results in terms of sound profile and typing feel. Users seeking a quieter typing experience can confidently choose either switch with the understanding that they will encounter similar acoustic qualities, thanks to the inherent properties of nylon. This makes both switches viable options for those prioritizing sound absorption and a more subdued keyboard experience, regardless of any subtle differences in tactile feedback or release sounds that may exist due to their construction variations.
Weight
The Cherry MX Silent Red and HMX SU linear switches both feature an actuation force of 45 grams, meaning they require the same amount of force to trigger a keystroke, which allows users to achieve similar typing responsiveness. However, the bottom out force differs between the two; while the MX Silent Red's bottom out force is unspecified, the HMX SU has a bottom out force of 50 grams, making it slightly heavier when pressed all the way down. This difference suggests that the HMX SU offers a more substantial feel when bottoming out, which may appeal to users who prefer a firmer typing experience. In contrast, the absence of a specified bottom out force for the MX Silent Red implies that it could be perceived as a lighter option overall, especially during prolonged use, making it potentially more comfortable for extended typing sessions. Therefore, if a user values a lighter switch for comfort and endurance, the Cherry MX Silent Red may be the better choice, whereas those seeking a heavier, more tactile experience might lean toward the HMX SU.
Travel distance
When comparing the travel distances of the Cherry MX Silent Red linear switch and the HMX SU linear switch, we find that the MX Silent Red has a travel distance of 3.7 mm, while the HMX SU measures slightly shorter at 3.6 mm. This means that the MX Silent Red offers a deeper press, which some users may prefer for a more tactile feel, while the HMX SU's shorter distance could provide quicker response times that are often favored by gamers seeking enhanced performance. Consequently, those who prioritize a more substantial depth in their keystrokes might lean towards the Cherry MX Silent Red, whereas users who favor faster actuation may opt for the HMX SU. Though the differences are minimal, the choice largely depends on personal preference for either a more pronounced travel or a snappier response.

Typing experience
When comparing the sound qualities of the Cherry MX Silent Red and the HMX SU linear switches, the differences in their audio signatures stand out. The MX Silent Red is characterized by a muted and thocky sound, striking a balance between being quietly efficient and offering a deep, satisfying thump when activated. It produces a low-pitched tone, which gives it a mellow and bass-heavy feel that is ideal for quiet environments. Conversely, there is no detailed sound profile provided for the HMX SU linear switch, which leaves some uncertainty about its auditory characteristics. However, it's important to remember that sound can be influenced by various external factors such as the choice of keyboard housing and keycaps.
In terms of tactile feel, the MX Silent Red features a textured sensation upon key press, which can provide a unique typing experience for those who appreciate a bit of friction as they type. This texture can enhance feedback, making it easier to discern when a key has been activated, but might not be preferred by everyone. On the other hand, the HMX SU linear switch does not have any specific feel descriptors available, leaving an unknown in this area. This makes it difficult to compare the tactile sensations directly, as personal preferences in switch texture can significantly influence a user's overall experience.
In conclusion, while both the Cherry MX Silent Red and the HMX SU linear switches serve different potential needs, there are clear strengths in the MX Silent Red's sound and feel qualities. The Silent Red offers an ideal solution for those looking for a quieter typing experience without sacrificing the satisfying auditory feedback of a mechanical switch. Without concrete information on the SU's sound and feel characteristics, it is hard to draw parallel experiences. Therefore, while you may enjoy a similar linear typing experience with both switches, the specific qualities in sound and feel where the Silent Red excels may not transfer to the HMX SU unless further details are provided.
Conclusion
To summarize, your choice between the Cherry MX Silent Red linear switch and the HMX SU linear switch ultimately hinges on your specific needs and environment. If you find yourself typing in a quiet workspace or a shared living area where noise can be disruptive, the MX Silent Red is the ideal option due to its muted sound profile and soft feel. You can enjoy the satisfaction of a classic linear switch without the clacks that can distract others. This switch also offers a textured experience, which some may appreciate for its tactile feedback. On the other hand, if you prefer a slightly lighter feel while still craving a deeper sound profile reminiscent of a thocky switch, the HMX SU may be your best bet. With its 50 grams of bottom-out force, the SU offers a smooth, responsive experience paired with a rich sound that can be satisfying without being overly loud. Choose the MX Silent Red for a serene typing experience and the HMX SU for a bit more character in both sound and feel. Ultimately, understanding your environment and typing preferences will guide you to the switch that enhances your mechanical keyboard experience.
