HMX SU vs. Bsun Tuzi (Bunny)
An in-depth look at the HMX SU and the Bsun Tuzi (Bunny) switches—which one is the best fit for you?
Overview
When it comes to choosing a mechanical keyboard switch, enthusiasts often find themselves torn between options like the HMX SU and the Bsun Tuzi (Bunny), both of which belong to the linear switch category but offer distinctly different experiences. The HMX SU stands out with its full PA12 housing and T5 stem, delivering a subtle yet relatively deep sound profile that appeals to users seeking a more subdued auditory feedback when typing. In contrast, the Bsun Tuzi (Bunny) offers a refined typing experience with its modified LY stem, featuring a PC top and PA bottom, which results in a unique combination of clack and smoothness, perfect for those who enjoy a high-pitched, silky sound while they type. While the HMX SU may be more suited for those who prefer a quieter environment, the Bsun Tuzi (Bunny) caters to those looking for an engaging auditory sensation. However, let's dive in a bit deeper beyond generalities so you can best decide on the right switch for your typing style and preferences.

Housing materials
The HMX SU and the Bsun Tuzi (Bunny) switches utilize different materials for their top housing, leading to distinct sound profiles during use. The HMX SU utilizes nylon for its top housing, which is known for its softer nature. This characteristic allows for a deeper and fuller sound profile, as the nylon absorbs more sound compared to harder plastics. Consequently, users can expect a duller and rounder auditory experience when typing on the HMX SU switches. In contrast, the Bsun Tuzi features a polycarbonate top housing that is firmer and stiffer. This construction results in a sharper, higher-pitched, and crisper sound profile that offers a more pronounced resonance. The transparent nature of polycarbonate also enhances its aesthetic appeal, making it an ideal choice for showcasing RGB lighting.
While the top housing materials differ significantly, both switch models exhibit similarities in their bottom housings. The HMX SU and the Bsun Tuzi both employ nylon for their bottom housing. As with the top housing of the HMX SU, the use of nylon in the bottom allows for a deeper and fuller sound profile. This uniformity means that when users type on the Tuzi, they will experience the familiar sound dynamics associated with nylon. Both models benefit from the inherent qualities of nylon, which helps absorb sound and create a smoother, more muted bottom-out sound. This consistency in bottom housing material plays a crucial role in moderating the overall auditory experience between the switches.
Overall, the contrasting materials of the top housings of the HMX SU and Bsun Tuzi create a distinct divergence in sound profiles, while their shared bottom housing material fosters a sense of continuity between the two. When a user engages either switch, they will experience the characteristic softness and sound absorption of the nylon bottom housing, bridging the auditory experiences. The variation in the top housing materials enhances the sound quality upon key release, offering a unique typing experience. In summary, while the switches may achieve similar depth and fullness in bottom-out sounds thanks to their nylon bases, the polycarbonate top of the Bsun Tuzi ensures a sharper auditory contrast that provides a different sensation when typing on either switch.
Weight
The HMX SU linear switch and the Bsun Tuzi (Bunny) linear switch offer distinct differences in their actuation and bottom out forces, catering to varying user preferences. The HMX SU features an actuation force of 45 grams and a bottom out force of 50 grams, making it a slightly heavier option compared to the Bsun Tuzi (Bunny), which has a lighter actuation force of 37 grams and a bottom out force of 42 grams. This difference in weight means that typing on the SU may feel more substantial to some users, while those who prefer a lighter touch would find the Bunny more comfortable for extended typing sessions. Both switches are deemed light in terms of overall force, but the Bunny's lower weights make it the more accessible choice for prolonged usability, perfect for long working hours or gaming marathons. In summary, if you seek a more responsive and less strenuous typing experience, the Bsun Tuzi (Bunny) linear switch is the preferred option due to its lower actuation and bottom out forces.
Travel distance
Both the HMX SU linear switch and the Bsun Tuzi (Bunny) linear switch feature an identical travel distance of 3.6 mm, meaning that users will experience the same level of keystroke engagement when pressing either switch. Since both switches have the same travel distance, they will deliver similar results in terms of feel and actuation, making either choice suitable for those who prefer a consistent key travel experience.

Typing experience
In terms of sound, the HMX SU linear switch delivers a subtle and relatively deep sound profile, providing a more understated acoustic experience. This caters to users who may prefer a muted typing ambiance, avoiding excessive noise during use. On the other hand, the Bsun Tuzi (Bunny) linear switch produces a clacky sound characterized by a sharp and snappy auditory feedback, as well as a high-pitched tone that can be described as crisp and bright. This makes the Tuzi a great choice for those who enjoy a more lively and engaging typing experience, but it may not be suitable for environments where quieter key presses are preferred.
Regarding feel, the HMX SU linear switch offers a smooth typing experience, though specific details about its tactile feedback are not provided. In contrast, the Tuzi (Bunny) is noted for its silky feel, which significantly enhances smoothness and minimizes resistance during keystrokes. This provides users with a luxurious typing sensation that many find satisfying, marking a distinct preference for those who value fluidity as a key part of their typing experience.
Combining all these aspects, one can appreciate that while the HMX SU linear switch favors a more subdued sound profile and offers a generally smooth feel, the Bsun Tuzi (Bunny) switch stands out with its sharp, lively acoustic feedback and notably silky experience. Therefore, depending on your priorities—be it a quieter environment or a more pronounced auditory and tactile experience—each switch caters to different preferences effectively. Both switches will deliver enjoyable performance, albeit with their unique characteristics that may sway your decision based on your intended use and personal preferences.
Conclusion
To conclude, when deciding between the HMX SU linear switch and the Bsun Tuzi (Bunny) linear switch, your preferences and typing style will significantly influence your choice. If you gravitate toward a slightly heavier feel and appreciate a subtle, deep sound profile, the SU might be the better fit. Its 50-gram actuation weight provides a tactile response that some find satisfying, especially during long typing sessions. On the other hand, if you prefer a lighter and more tactile experience with a crisp, clacky sound, the Bsun Tuzi (Bunny) is likely more aligned with your needs. Weighing in at just 42 grams, its silky smooth action and high-pitched sound can enhance not only your typing comfort but also the auditory experience, making it an enticing option for casual gaming or day-to-day typing. Ultimately, both switches are excellent choices; you just need to assess your personal typing preferences and the kind of sound and feel you are seeking to make the best choice for your mechanical keyboard.
