HMX 1989 vs. TTC Yunhai
An in-depth look at the HMX 1989 and the TTC Yunhai switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, the choice between the HMX 1989 and the TTC Yunhai can significantly influence your typing and gaming experience. The HMX 1989, known for its deep and thocky sound profile, offers a robust tactile experience that appeals to those who enjoy a more pronounced feedback with each keystroke. Its solid construction makes it a popular option for gamers looking for reliability during intense sessions. On the other hand, the TTC Yunhai switches provide a remarkably light actuation force, accompanied by a smooth and rounded sound profile, catering to typists who favor a softer touch and less resistance in their typing. While both switches fall under the linear category, they present distinct characteristics that can suit varying preferences and needs. However, let’s dive in a bit deeper beyond generalities so you can best decide on the switch that is right for you.

Housing materials
The housing materials of the HMX 1989 and the TTC Yunhai reflect distinct design philosophies and sound characteristics, primarily stemming from their different choices for top housings. The HMX 1989 utilizes a polycarbonate top housing, contributing to a sharper, higher-pitched sound profile that resonates clearly during typing. This is due to polycarbonate's stiffer composition, which allows for a more pronounced sound. In contrast, the TTC Yunhai employs a nylon top housing, which tends to absorb more sound and produce a deeper, fuller sound profile. This stark difference between the materials suggests that the HMX 1989 is optimized for a more vibrant auditory experience, while the Yunhai prioritizes a softer, more rounded sound.
When examining the bottom housings of both switches, we find an interesting alignment, as both the HMX 1989 and the TTC Yunhai utilize nylon. This choice in material leads to a similar sound output in terms of depth and fullness, regardless of the contrasting upper housings. The nylon's inherent properties allow it to absorb sound effectively, resulting in a duller sound that is consistent across both models when the key is bottomed out. Consequently, while the upper housings of the two designs delineate their overall sound profiles, the use of nylon in both bottom housings lends them a common structural characteristic that unites them in terms of sound.
In conclusion, the combination of polycarbonate in the HMX 1989's top housing with a nylon bottom housing yields a unique sound experience that can be notably different from the all-nylon construction of the TTC Yunhai. The separation of characteristics highlights how top and bottom housings interact in influencing the overall typing experience. While the 1989 leans towards a high-resolution auditory output thanks to its polycarbonate top, the Yunhai offers a rounded, softer response, showcasing how different materials can effectively shape the final acoustic result and tactile feedback of each switch. Despite these differences, the similar nylon bottom housing in both models assures a consistent underlying sound quality that contributes positively to their overall performance.
Weight
When comparing the actuation and bottom out forces of the HMX 1989 linear switch and the TTC Yunhai linear switch, we see some noteworthy distinctions. The HMX 1989 has an actuation force of 45 grams and a bottom out force of 53 grams, categorizing it as medium-light, while the TTC Yunhai offers a slightly lighter actuation force of 42 grams and a bottom out force of 50 grams, placing it in the light category. This indicates that users who prefer a lighter typing experience may find the Yunhai to be more comfortable for long typing sessions or gaming marathons, as it requires less force to actuate a key. In contrast, the HMX 1989, being heavier, might appeal to those who enjoy a more substantial typing feel. Both switches exhibit a similar gap between actuation and bottom out forces, suggesting that both maintain a consistent typing experience without sudden jumps in resistance. Overall, while both switches provide a good range of force options, the TTC Yunhai is the lighter choice.
Travel distance
When comparing the travel distance of the HMX 1989 linear switch and the TTC Yunhai linear switch, a clear distinction emerges. The HMX 1989 features a travel distance of 4 mm, making it the longer option, while the TTC Yunhai offers a shorter travel distance of 3.6 mm. This difference can impact the typing experience significantly; the HMX 1989's greater depth may appeal to those who enjoy a more satisfying keystroke, providing a hearty feel with each press. On the other hand, the Yunhai's shorter travel distance can cater to gamers and those seeking quicker response times, making it more suitable for fast-paced environments. Thus, individuals should consider their preferences for key depth versus responsiveness when choosing between these two switches.

Typing experience
The HMX 1989 linear switch is celebrated for its deep, thocky sound, which creates a satisfying auditory experience reminiscent of classic mechanical keyboards. This substantial sound profile can be particularly enjoyable for those who appreciate a more resonant typing environment. In comparison, the TTC Yunhai linear switch produces a unique, deep, rounded sound that is less aggressive but equally appealing. While both switches feature distinct sound characteristics, they share a level of depth that enhances the overall auditory feedback during typing. It is important to note that the ultimate sound experience is also influenced by factors such as the keyboard's design and the type of keycaps used.
When it comes to the feel of each switch, the HMX 1989 is known for delivering a robust tactile response that can inspire confidence with each keystroke. This switch’s curvature is designed to provide a well-rounded typing experience that adds to its overall charm. On the other hand, the TTC Yunhai switch offers a significantly lighter actuation force, making it feel effortless to type on, which greatly appeals to users who prefer a gentle touch. The contrast in feel between these two switches can cater to different preferences; the HMX 1989 may suit typists looking for that sturdiness, while the Yunhai is perfect for those who want a smooth and light touch without sacrificing responsiveness.
In conclusion, while the HMX 1989 and TTC Yunhai linear switches each offer distinct sound and feel characteristics, they both deliver a satisfying typing experience with their deep auditory profiles. The HMX 1989 excels in a thocky sound and more substantial tactile feedback, making it ideal for those who enjoy a more pronounced typing environment. Conversely, the TTC Yunhai provides an effortlessly light experience, perfect for typists who favor a softer touch. Ultimately, your choice will depend on whether you prioritize depth and sturdiness or a gentle, smooth actuation. Both options remain compelling choices in the mechanical keyboard space, catering to different preferences and styles of typing.
Conclusion
In summary, when choosing between the HMX 1989 linear switch and the TTC Yunhai linear switch, your preferences for actuation force, sound profile, and overall feel will be critical in determining the best option for you. If you enjoy a medium-light bottom-out force and are seeking a deeper, thocky sound that provides a more pronounced feedback with each keystroke, the HMX 1989 would be the preferable choice. This switch is particularly beneficial for gamers or those who engage in fast-paced typing where you might appreciate the satisfying sound and tactile feedback. On the other hand, if you favor an effortless typing experience with a lighter 50-gram actuation and a unique, rounded acoustic profile, the TTC Yunhai is ideal for you. This switch excels for typists who prioritize a smooth and gentle feel, making it perfect for long typing sessions or for those who prefer a more muted sound. Ultimately, your decision should be based on the specific characteristics that align best with your typing style—whether it's the robust thock of the HMX 1989 or the soft, airy feedback of the Yunhai, both switches have unique advantages that cater to different preferences.
