HMX SU vs. Bsun Taichi

Overview

When it comes to mechanical keyboard switches, the HMX SU and Bsun Taichi provide distinct yet compelling options for enthusiasts seeking a linear experience. The HMX SU is recognized for its full PA12 housing and T5 stem, delivering a subtly deep sound profile that offers a muted auditory experience, perfect for those who prefer a stealthier operation while typing or gaming. On the other hand, the Bsun Taichi switches captivate users with their enchanting high-pitched bottom-out sound, facilitated by a long-pole stem and extended springs, which contribute to an exceptionally smooth and stable typing experience. While the SU may appeal to users seeking a balanced, less intrusive acoustic environment, the Taichi caters to those who desire a more pronounced auditory feedback along with seamless keypresses. However, let's dive in a bit deeper beyond generalities so you can best decide on the optimal switch for your unique preferences and typing style.

Housing materials

The HMX SU and the Bsun Taichi switches exhibit distinct differences in their top housing materials, each contributing uniquely to the overall typing experience. The HMX SU utilizes nylon for its top housing, a material known for its softer characteristics that promote a deeper and fuller sound profile. This structure allows the switches to absorb sound effectively, resulting in a duller and rounder acoustic signature. In contrast, the Bsun Taichi employs polycarbonate for the top housing, which enhances clarity and brightness. The stiffer nature of polycarbonate produces a sharper, higher-pitched, and crisper sound. Therefore, while both switches serve the same primary function, the materials used for the top housing lead to contrasting auditory experiences during use.

The bottom housing of both switches, however, tells a different story. Both the HMX SU and the Bsun Taichi rely on nylon for their bottom housing. This shared use of nylon means that both switches exhibit a deeper and fuller sound profile during typing, regardless of the differing materials used in their top housings. As nylon is a classic choice known for its sound-absorbing qualities, it creates a consistent acoustic characteristic that emphasizes the softer tonal qualities. Consequently, when a user presses down on either switch, the additional resonance and sound absorption provided by the nylon bottom housing come into play, delivering a balanced bottom-out sound and feel that is satisfying and cohesive across both models.

When considering the overall experience, it's essential to note that the combination of housing materials influences how each switch feels and sounds during different stages of key presses. The nylon bottom housing from both switches plays a significant role in the tactile feedback and sound when keys are bottomed out, while the differing top housings dictate the sound profile released upon key release. Users can expect a distinct clarity from the polycarbonate in the Bsun Taichi while enjoying the deeper tones from the nylon found in both models. Ultimately, even though the materials differ, the choices made in the design of the top housing against a common bottom housing can lead to varying yet complementary sound profiles that cater to different user preferences.

Weight

When comparing the HMX SU linear switch and the Bsun Taichi linear switch, we find distinct differences in their actuation forces, which significantly affect the typing experience. The HMX SU requires an actuation force of 45 grams and has a bottom out force of 50 grams, making it a light switch overall, which is beneficial for users who type for extended periods or engage in long gaming sessions. In contrast, the Bsun Taichi features a lighter actuation force of 40 grams, although its bottom out force remains unspecified. Since the Taichi's actuation force is lower than that of the HMX SU, it could potentially offer an even easier keystroke experience, but without the bottom out force data, we cannot assess its overall impact on user experience fully. Thus, the SU is the heavier option in terms of actuation and bottom-out forces, while the Taichi is lighter, appealing to those seeking a softer touch. If both switches had comparable bottom-out forces, one could expect similar overall user experiences despite the slight difference in actuation force.

Travel distance

Both the HMX SU linear switch and the Bsun Taichi linear switch feature the same travel distance of 3.6 mm. This equal travel distance means that users will experience a similar feel and actuation when pressing down on keys equipped with either switch. As a result, for those seeking a consistent typing experience, both switches will deliver comparable performance in terms of key travel and feedback.

Price comparison

Typing experience

In terms of sound, the HMX SU linear switch offers a subtle and relatively deep sound profile, thanks to its full PA12 housing and T5 stem. This results in a muted auditory experience that is less jarring compared to some other switches. On the other hand, the Bsun Taichi linear switch is characterized by a distinctively high-pitched bottom-out sound, produced from its long-pole stem and extended springs. This combination gives the Taichi an enchanting and vibrant auditory signature that can be more attention-grabbing when bottoming out. It's important to note that the overall sound experience can vary significantly based on factors such as your choice of keyboard and keycaps.

When it comes to feel, the HMX SU switch is typically recognized for its smoothness and consistent actuation, contributing to an enjoyable typing experience. The T5 stem ensures a reliable response without any noticeable tactility, making it well-suited for long typing sessions. Conversely, the Bsun Taichi switch is designed with an emphasis on unparalleled smoothness and stability due to its extended springs and walled stem. This results in a feel that many users find incredibly fluid, enhancing the tactile experience during both typing and gaming.

In conclusion, both the HMX SU and Bsun Taichi linear switches offer distinct auditory and tactile experiences. The SU's deep sound and smooth feel cater to those who prefer a more subdued typing experience, while the Taichi's high-pitched sound and silky feel appeal to users looking for something more lively. Ultimately, the choice between these switches will depend on personal preferences regarding sound and feel, but both options promise quality performance in their respective characteristics.

Conclusion

To conclude, your choice between the HMX SU linear switch and the Bsun Taichi linear switch should hinge on your specific preferences for tactile feedback and sound profile. If you prefer a lighter actuation force paired with a deeper, more subtle sound, the HMX SU is an excellent choice. Its full PA12 housing and T5 stem provide a satisfying experience for typists and gamers who enjoy a quieter keypress without sacrificing performance. On the other hand, if you are drawn to a more pronounced acoustic experience and value a smooth feel during your typing or gaming sessions, you might find the Bsun Taichi switch more appealing. Known for its enchanting high-pitched bottom-out sound and stability resulting from its long-pole stem and extended springs, the Taichi is designed for those who seek a more dynamic auditory feedback while also enjoying a smooth keystroke. In the end, your decision should reflect whether you prioritize a lighter, subtle typing experience with the HMX SU, or a more interactive and resonant one with the Bsun Taichi.
