Bsun Tuzi (Bunny) vs. HMX Xinhai (Heavy)
An in-depth look at the Bsun Tuzi (Bunny) and the HMX Xinhai (Heavy) switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboards, the choice of switch can significantly influence your typing experience, and this is where the Bsun Tuzi (Bunny) and the HMX Xinhai (Heavy) come into play. The Tuzi switch is celebrated for its refined tactile feedback, characterized by a modified LY stem that harmonizes with a PC top and PA bottom to deliver a unique blend of clack and smoothness, making it ideal for users who appreciate a high-pitched and silky typing feel. On the other hand, the Xinhai switch, crafted with a PA12 top housing and a POM stem, offers a heavier touch with softer acoustics yet still maintains crisp resonance for a sophisticated typing experience. While both switches are linear—favoring steady keystrokes without tactile bumps—each brings a distinct personality to the table: the Tuzi with its clacky flair and the Xinhai with its refined, crisp precision. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
When comparing the housing materials of the Bsun Tuzi (Bunny) and the HMX Xinhai (Heavy), a notable contrast is evident between their top housings. The Tuzi utilizes a polycarbonate top housing while the Xinhai features a nylon top housing. This difference significantly affects the sound profile of each switch. The polycarbonate material lends a sharper and crisper auditory experience due to its stiffer nature, resulting in clearer, more resonant sounds. This is particularly beneficial for users who appreciate a pronounced sound when typing, especially when RGB lighting is involved, as the translucency of the polycarbonate enhances visual effects. In contrast, the nylon top housing of the Xinhai creates a deeper and fuller sound profile, with a softer texture that absorbs sound and produces a duller, round sound. This gives a more muted effect, appealing to users who prefer a less intrusive auditory feedback while typing.
Both switches utilize nylon for their bottom housings, which fosters a similarity in sound profile for that component. The nylon's impact is crucial as it greatly affects the bottom-out sound and feel when the key is fully pressed. In both the Bsun Tuzi and the HMX Xinhai, the use of nylon creates a deeper, more resonant experience under the finger. This shared material choice ensures that regardless of the top housing's distinct properties, users of either switch can expect a consistent, fuller sound when the key is engaged to the bottom. Despite the differences in the top housing materials, the nylon bottom housing provides a unifying element in their performance that resonates well with typing enthusiasts who favor a plush feel.
Ultimately, while the Bsun Tuzi and the HMX Xinhai differ in their top housing materials, the incorporation of nylon in both bottom housings yields complementary auditory qualities. For users focused on the typing experience, the combination of the crispness from the Tuzi's polycarbonate top and the fullness of the nylon bottom creates a dynamic sound profile, while the Xinhai, with its all-nylon construction, offers a consistent sound experience that leans towards the subdued. This comparison demonstrates how different materials can affect a switch's performance while still allowing for commonalities, fostering preferences based on individual typing styles and sound preferences.
Weight
The Bsun Tuzi (Bunny) linear switch and the HMX Xinhai (Heavy) linear switch present a clear contrast in both actuation and bottom out forces. The Tuzi switch features a light actuation force of 37 grams and a bottom out force of 42 grams, making it well-suited for prolonged typing sessions and gaming due to its minimal resistance. In comparison, the Xinhai switch has a heavier actuation force of 55 grams and a bottom out force of 62.5 grams, appealing to those who prefer a more substantial typing experience. While the Tuzi is the lighter option, offering an easier keystroke that requires less effort, the Xinhai provides a firmer tactile feedback that some users may find more satisfying. Ultimately, for typists who prioritize comfort over long durations, the Tuzi would likely be the preferred choice, whereas those seeking a stronger push should gravitate toward the Xinhai.
Travel distance
When comparing the travel distances of the Bsun Tuzi (Bunny) linear switch and the HMX Xinhai (Heavy) linear switch, the Bunny switch has a travel distance of 3.6 mm, while the Heavy switch measures at 3.4 mm. This makes the Bunny switch the longer option, providing a more substantial keypress that some users may find more satisfying and deeper. In contrast, the Xinhai’s shorter travel distance may appeal to gamers or users who prioritize quicker response times, as it allows for faster actuation. Although both switches fall within the more modern range of travel distances, the Bunny's extra 0.2 mm can create a noticeably different tactile experience, leaning towards a more deliberate feel, while the Heavy switch conveys a snappier and more immediate response. Ultimately, the choice between the two will depend on personal preference for depth versus speed during key presses.

Typing experience
The sound profile of the Bsun Tuzi (Bunny) linear switch is characterized by its clacky and high-pitched qualities, producing a sharp and percussive auditory experience with each keystroke. This makes the Tuzi particularly appealing for users who appreciate a more lively and bright soundscape that can enhance the typing experience, especially in a setting where auditory feedback is valued. In contrast, while the HMX Xinhai (Heavy) is noted for its softer acoustics profile, specific descriptions of its sound characteristics, such as clackiness or pitch, are currently unknown. Therefore, while users may expect a more subdued auditory experience from the Xinhai, further details would be needed to draw direct comparisons.
When it comes to feel, the Tuzi (Bunny) switch stands out for its silky smoothness, providing an exceptionally refined typing experience that minimizes key resistance and enhances user comfort during prolonged typing sessions. This tactile quality appeals to typists who favor a seamless and fluid keystroke. The HMX Xinhai (Heavy) does not have detailed information available regarding its tactile feedback, which leaves its feel relatively ambiguous at this time. Thus, for those seeking a smooth typing experience, the Tuzi clearly has the advantage, while the Zinhai's feel remains a mystery.
In conclusion, the Bsun Tuzi (Bunny) linear switch shines through with its clacky and high-pitched sound, combined with an incredibly silky feel, making it an excellent choice for users who prioritize both auditory feedback and smoothness. The HMX Xinhai (Heavy), while likely offering a different acoustic profile, lacks specific details regarding its sound and feel, leaving potential users eager for more information. Overall, if you are looking for a lively auditory typing experience with a smooth keystroke, the Tuzi is your go-to choice, while the Xinhai may require further exploration to understand its unique attributes fully.
Conclusion
To conclude, the choice between the Bsun Tuzi (Bunny) linear switch and the HMX Xinhai (Heavy) linear switch ultimately comes down to your specific preferences for typing feel, sound, and actuation force. If you prefer a lighter switch that provides a refined and silky typing experience with a clacky and high-pitched sound, the Tuzi (Bunny) is an excellent choice, especially if you enjoy a more responsive feel while typing or gaming. Its lower actuation force of 42 grams allows for quicker key presses, making it suitable for fast-paced tasks. On the other hand, if you enjoy a more substantial keypress and a slightly firmer typing experience, the Xinhai (Heavy) switch with its 62.5-gram bottom-out force will provide that medium resistance. This switch combines softer acoustics with a crisp, higher-pitched resonance, making it a good fit for users seeking an elegant balance of performance and sound without compromising on typing comfort. Ultimately, your decision should reflect your typing style, the sound profile you prefer, and whether you lean towards a lighter or heavier switch feel.
