Gateron Milky Red Pro (KS-3) vs. HMX SU
An in-depth look at the Gateron Milky Red Pro (KS-3) and the HMX SU switches—which one is the best fit for you?
Overview
When comparing mechanical keyboard switches, the Gateron Milky Red Pro (KS-3) and the HMX SU showcase the diversity within linear switches, each catering to unique preferences among typists and gamers alike. The Gateron Milky Red Pro is celebrated for its buttery smooth keystrokes and rich, low-pitched "thock" sound, making it a favorite for those who prioritize a pleasant auditory experience alongside tactile ease during extended typing sessions. In contrast, the HMX SU offers a sturdy full PA12 housing paired with a T5 stem, delivering a subtly deeper sound profile that appeals to those valuing a more refined auditory feedback without overpowering noise. While both switches deliver a smooth linear experience, their distinct sound characteristics and construction materials may sway your choice depending on whether you seek auditory pleasure or understated solidity. However, let’s dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The Gateron Milky Red Pro (KS-3) and the HMX SU switches both feature nylon housings, which significantly influence their acoustic and tactile performance. The use of nylon for both the top and bottom housings of these switches offers a classic advantage— the material provides a deeper and fuller sound profile during typing. Since both switches utilize nylon, the characteristics of sound and feel produced by each switch are likely to be similar. The inherent properties of nylon, being a softer plastic, allow for better sound absorption compared to harder materials, which results in a more muted and rounder auditory experience for users of both switches.
Although the materials used in both the Milky Red Pro (KS-3) and HMX SU are identical, it's essential to recognize the nuanced impact each housing (top and bottom) has on the overall performance. When a user presses a key, it is primarily the bottom housing that contributes to the bottom-out sound and tactile feedback experienced. Since both switches employ nylon for the bottom housing, one can expect similarly satisfying sounds and feelings upon key actuation. Conversely, the top housing influences the sound profile when keys are released. With both switches utilizing nylon for the top housing as well, the auditory quality during the release phase will also likely yield comparable results across both models.
In summary, the parallel use of nylon for both the top and bottom housings in the Gateron Milky Red Pro (KS-3) and HMX SU switches positions them to deliver a similar auditory experience and tactile feedback. The softness of nylon ensures a sound profile that is rich and resonant, regardless of the brand. As a result, typists can anticipate a consistent experience when using either switch, making personal preferences for one model over the other largely subjective, as the fundamental sound and feel characteristics remain consistent due to the shared housing material.
Weight
When comparing the Gateron Milky Red Pro (KS-3) linear switch and the HMX SU linear switch, both exhibit the same actuation force of 45 grams, meaning users can expect a similarly easy keystroke when triggering a key press. However, the bottom out forces differ slightly, with the Milky Red Pro requiring 52 grams to bottom out, while the HMX SU bottoms out at a lighter 50 grams. As a result, the HMX SU switch can be classified as the lighter option overall, making it more suitable for individuals who prefer a softer touch for extended typing sessions or gaming marathons. Conversely, the Gateron Milky Red Pro feels a bit heavier when fully bottoming out, catering to users who appreciate a more substantial feedback from their switches.
Travel distance
The Gateron Milky Red Pro (KS-3) linear switch and the HMX SU linear switch differ in their travel distances, with the former measuring 4 mm and the latter 3.6 mm. This means that the Milky Red Pro has a longer travel distance, offering a more pronounced keypress experience, which some users may prefer for its hearty depth. In contrast, the HMX SU's shorter travel distance of 3.6 mm may appeal more to gamers or those seeking quicker response times, as it allows for faster actuation. While both switches are linear and lack tactile feedback, the variation in travel distance suggests that users may experience different levels of responsiveness and depth in their typing or gaming. Those who prefer a more traditional feel will likely gravitate towards the Milky Red Pro, while those who enjoy a snappier press may favor the HMX SU.

Typing experience
When it comes to sound, the Gateron Milky Red Pro (KS-3) switches are known for their low-pitched, thocky sound profile. This results in a satisfying auditory experience characterized by a deeper, bassy tone that many users find appealing. They produce a rich, soft "thud" or "knock" when a key is pressed, which can enhance the overall typing experience. On the other hand, the HMX SU switches do not have specific information detailing their sound characteristics, so direct comparisons can't be drawn. However, since sound is influenced by the keyboard design and keycap material, users might achieve a comparable auditory experience depending on their build choices.
In terms of feel, the Milky Red Pro switches shine with a buttery smoothness that facilitates a seamless typing experience. This characteristic allows for effortless keystrokes, making them ideal for long typing sessions or gaming marathons. Unfortunately, the specifics regarding the feel of the HMX SU switches are unknown, so a direct comparison cannot be made. That said, those familiar with linear switches can expect a level of smoothness inherent in this switch category, which may result in a similar typing experience.
Overall, while the Gateron Milky Red Pro (KS-3) switches are celebrated for their deep, thocky sound and buttery feel, the HMX SU's auditory and tactile profiles remain undetermined. If users prioritize a known quantity, the Milky Red Pro offers a robust, satisfying experience. However, the HMX SU's performance remains a mystery, suggesting potential for surprising qualities, particularly with the right setup. Ultimately, personal preference and specific use cases will play a significant role in guiding newcomers to their ideal switch choice.
Conclusion
To conclude, your choice between the Gateron Milky Red Pro (KS-3) and the HMX SU linear switch should be based on your personal preferences for typing feel and sound profile, as well as your intended usage. If you value a medium-light actuation force of 52 grams that provides a buttery smooth typing experience, along with a pleasingly low-pitched, thocky sound, the Milky Red Pro would be an excellent choice. It excels in providing a rich acoustic feedback that many typists find satisfying, making it great for both typing and gaming. On the other hand, if you prefer an even lighter actuation with a force of only 50 grams and enjoy subtle sound without the added depth of the Milky Red Pro, the HMX SU might be better suited for you. Its full PA12 housing and T5 stem offer a unique feel, and while it doesn’t have the same bassy tone, it delivers a respectable typing experience that might appeal to users looking for something less pronounced. Ultimately, both switches have their own merits, so consider what aspects are most important to you in a switch to make the most informed decision.
