KTT F2 vs. HMX SU

Overview

When it comes to mechanical keyboard switches, the KTT F2 and HMX SU linear switches offer distinct characteristics that cater to different typing preferences and experiences. The KTT F2 switches are celebrated for their unique hollow sound signature, which creates an auditory experience that is both distinct and pleasing. Their medium-light weight makes for a balanced typing feel, allowing for comfortable feedback without being overly forceful. Additionally, the lightly textured surface of each key enhances the overall tactile experience, giving typists a subtle yet rewarding sensation with each keystroke. In contrast, the HMX SU switches come equipped with a full PA12 housing and a T5 stem, producing a deeper and more uniform sound profile that delivers a different auditory ambiance. While both switches are classified as linear, the KTT F2 leans towards a feathery and mild touch, whereas the HMX SU provides a more robust yet still smooth feel. Ultimately, the choice between these two switches boils down to personal preferences in sound and tactile feedback. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

The KTT F2 and HMX SU switches employ distinctly different materials for their top housings that significantly influence their acoustic characteristics. The F2 utilizes polycarbonate for its top housing, which is known for its stiffness and ability to deliver a sharp, high-pitched sound profile. This material's translucency also contributes to its compatibility with RGB lighting, enhancing both the aesthetic and functional aspects of the switch. In contrast, the HMX SU features a nylon top housing, a classic choice that typically results in a deeper, fuller sound. The softer nature of nylon absorbs sound more effectively, rendering a rounder sound profile when the keys are pressed. Thus, while the F2’s polycarbonate top is engineered for clarity and brightness, the SU’s nylon top is designed for warmth and richness in tone.

Examining the bottom housing of the KTT F2 and HMX SU reveals a similar pattern where differences in material contribute to their distinct sound qualities. The F2 again employs polycarbonate, emphasizing a crisp resonance that enhances the overall auditory experience when bottoming out. Just as with the top housing, this stiffness ensures a clear sound profile that complements the switch’s performance. In contrast, the HMX SU’s nylon bottom housing continues the theme of absorption, adding to the deeper, rounded sound profile typical of nylon materials. Therefore, whereas the polycarbonate bottom housing of the F2 amplifies brightness in sound, the nylon housing of the SU softens the auditory impact, creating a more subdued experience.

In terms of overall performance, the varying materials of the KTT F2 and HMX SU result in differentiated sound profiles that cater to distinct preferences. If the top and bottom housings are made from different materials, the interplay between these housing characteristics becomes crucial to the switch's behavior. In both switches, the bottom housing has a more pronounced influence on the bottom-out sound and feel due to the impact when keys are pressed down. Conversely, the top housing material significantly influences the sound produced when releasing the key. In essence, while the KTT F2 provides a sharper and more resonant experience due to its polycarbonate construction, the HMX SU offers a fuller and warmer sound profile attributed to its nylon materials. Users can thus select based on their sound preferences while recognizing how the combined properties of each housing material play a critical role in the overall switch experience.

Weight

The KTT F2 linear switch and the HMX SU linear switch present distinct characteristics in terms of actuation and bottom out forces, catering to different typing preferences. The F2 has an actuation force of 43 grams and a bottom out force of 53 grams, making it a medium-light switch. In contrast, the SU requires slightly more force to actuate at 45 grams but has a lower bottom out force of 50 grams, categorizing it as a light switch. This difference in actuation force means that the F2 may offer a slightly easier keystroke trigger, appealing to those who prefer less resistance, particularly for extended typing or gaming. However, the SU’s bottom out force is lower, which could enhance the feeling of control when bottoming out. Overall, the F2 could be considered the heavier of the two based on actuation, while the SU is lighter overall. Ultimately, users who favor substantial feedback and a heavier push might lean towards the F2, whereas those seeking a more effortless keystroke experience could opt for the HMX SU.

Travel distance

When comparing the travel distance of the KTT F2 linear switch and the HMX SU linear switch, the F2 has a travel distance of 3.5 mm, while the SU measures slightly longer at 3.6 mm. This makes the KTT F2 the shorter option, offering quicker response times that many gamers may prefer for rapid key presses. On the other hand, the HMX SU, with its greater travel distance, may provide a more substantial feel that some users appreciate for its deeper engagement. While both switches are relatively close in distance, the choice between them ultimately hinges on personal preference: those seeking a more responsive experience might gravitate towards the KTT F2, whereas those who enjoy a more pronounced keystroke may favor the HMX SU.

Price comparison

Typing experience

In terms of sound, the KTT F2 linear switch features a distinct hollow sound signature that sets it apart, delivering a neutral and subdued auditory experience. This makes it suitable for a variety of environments, be it a quiet office or a home setting. Users can expect a moderate actuation force that neither overwhelms nor underwhelms, allowing it to cater to both beginners and advanced typists alike. While the sound of the F2 is dampened to some degree, the specifics of the HMX SU linear switch's sound profile remain unknown, although it is noted to produce a relatively deep sound. This suggests that the SU may present a more pronounced auditory experience compared to the softly nuanced F2.

When it comes to the feel of the switches, the KTT F2 stands out with a relatively light, feathery quality that minimizes finger fatigue during extended typing sessions. Its mild and subtle characteristics offer a gentle yet satisfying typing experience, making it approachable for users of all typing styles. Unfortunately, the feel of the HMX SU linear switch is not specified, which leaves uncertainty as to how it may compare in this regard. This absence of information means that potential users should remain open to exploring the SU to see how it stands up against the nuanced feel of the F2.

Overall, both the KTT F2 and the HMX SU linear switches cater to users seeking linear designs, though they present distinct auditory experiences and an uncertain comparison in terms of tactile feedback. While the F2 is celebrated for its light, comfortable touch and subdued sound, the SU promises a deeper auditory profile, though how it feels is still to be determined. Users looking for similar experiences across these switches may find themselves gravitating towards the F2 for its well-defined qualities, while maintaining an open mind about the unique characteristics of the SU.

Conclusion

To conclude, when choosing between the KTT F2 and the HMX SU linear switches, consider your specific needs and preferences. If you value a balanced typing experience with a moderate actuation force, the KTT F2 is a strong contender. Its medium-light weight and lightly textured feel complement its distinct hollow sound signature, making it suitable for both work and gaming environments, particularly if you're looking for a switch that provides a touch of auditory personality without being overwhelming. On the other hand, if you prefer something lighter that offers a more subdued experience, the HMX SU linear switch might be your best choice. With a bottom-out force of just 50 grams, it’s excellent for extended typing sessions and shared spaces, as it provides a pleasant, deeper sound profile while maintaining a gentle touch. Ultimately, your choice should reflect how you intend to use your keyboard—whether for productivity, gaming, or leisure—and the kind of auditory and tactile feedback you're looking for in your typing experience.
